Gladiolus is a perennial favored for its beautiful, showy flowers. Its flowers grow on tall spikes and are often found in cutting gardens or in the back along the border (because they are tall). Gladioli have many different colored flowers, and grow between 2 to 6 feet in height. It’s good for cut flowers.

Planting

  • Plant gladiolus bulbs in the spring once danger of frost has passed and the soil has warmed.
  • Ready your garden by using a garden fork or tiller and loosen the soil to about 12 to 15 inches deep. After loosening the soil, mix in a 2– to 4–inch layer of compost.
  • Set the corm in the hole about 4 inches deep with the pointed end facing up. Cover with soil and press firmly.
  • Space the corms 3 to 6 inches apart. Water the corms thoroughly.
  • Gladioli like well-drained, light soil and full sun.
  • If you’re planting tall varieties, be sure to stake them at planting time. Be careful not to damage the corms with the stakes.
  • It takes about 90 days from the time gladioli are planted to root, grow, bloom, and store enough energy for the next season.

Care

  • Put a 2– to 4–inch layer of mulch around your gladioli to keep your soil moist and help prevent weeds.
  • If you get less than 1 inch of rain a week, water your plants regularly throughout the summer. Otherwise, water them moderately when in growth to keep the soil moist.
  • Remove the faded/dead flowers to ensure continuous growth. Once all the flowers on a stalk have gone, cut off the stalk.
  • Be sure to leave the plant intact so it can mature and rejuvenate the corms for the next season.
  • If you live in zones 7 or 8, put down a layer of hay or straw for winter protection.
  • Corms should be dug before the first frost if you live in zone 7 or ones colder. See instructions below.

Pests/Diseases

Harvest/Storage

Before the first frost, you can dig up glads to store over the winter.

  • Use a space and dig up cothe entire plant, grasping the top to pull it out of the soil. Avoid bruising or injuring corms while digging. Shake off all loose soil and discard damaged corms. Cut the stalk within 1 inch above the corm. Save the small cormels separately if you so desire.
  • Allow the corms to dry in the Sun for 1 or 2 days if the weather agrees. Sift out excess soil and place corms in wooden flats or trays. Cure ina warm and airy location for 2 weeks (at a temperature of 80-85°F). Remove and throw away the oldest bottom corms (from the base of the new one).
  • Dust freshly dug, clean corms with a fungicide (“bulb dust”) to avoid disease problems. Place dust and bulbs or other structures in a paper sack and shake vigorously.
  • Store the large, new corms in paper boxes, open paper bags, cloth bags, wooden trays with screen bottoms, or old onion sacks. Stack or hang the containers so air can move among them. Store the corms at 35 to 45°F in low humidity. A cool basement is quite suitable. Do not
    allow corms to freeze.
  • Replant these corms in the spring for another year of beautiful blooms.

No Glad Flowers

I live on the coast of Washington State. In April or May, (can't remember exactly when) I planted about 30 corms, in individual holes, along the sunny edge of my back deck. Each hole was filled with Miracle Grow planting soil and about a teaspoon of bone meal. Its now the middle of July and all I have are leaves, varying from 12-24" high. no evidence of stalks or flowers. Any ideas?

Gladiolus Not Blooming

Hi Ted,

I wonder if they were planted too deep and/or the corms are too wet. Once the foliage dies back this year, dig and reset them for next year. They should be 3 to 5 inches deep.

Glads - to plant or to wait until next year

Hello:

I have three dozen glad bulbs that were intended for planting this spring. We needed to dig up a water line and so garden planting in this location was put on hold. We are located in Hardiness zone 5b.

Should I try to plant these now in mid-July or can I just keep them and plant them next spring? If this is the better option, please advise how best to store the corns/bulbs between now and spring 2017.

Thank you.

I have EXACTLY the same

I have EXACTLY the same question!

Midsummer Bulb Planting

Hi Jean (and JB),

At this point in the season, it would probably be best to store them for planting next spring. Cut off any remaining foliage and make sure corms are good and dry. Cure them for two weeks in a warm, airy location. Then, remove the small cormels, keeping the largest of the corms. Tie them into a mesh sack in a well-ventilated room kept at a consistent temperature somewhere between 35 and 50 degrees Fahrenheit. They should be good to go next year!

When/how to transplant gladiola?

We want to dig up a few of our plants to share with a friend, who will share some theirs (different colors than we have). When/how do we do this?

Digging Gladiolus

Hi Ginny,

Wait about six weeks after the plants are done blooming. Then, use a spade fork to gently loosen and lift the soil around the corms (be mindful not to puncture them). Pull them out, give them a rinse, let them dry in the sun, and swap away!

gladiolus flowers

why are my flowers dying as soon as they bloom,and why are the stalks leaning over and breaking,is there a certain way to plant,mine are at the end of my yard in a straight line ,should they be planted more of a bush like plant

Planting Gladiolus

Hi Debora,

The best way to plant gladiolus is to space the corms about 4 to 6 inches apart (whether in a grouping or in a line formation). What is key is staking tall varieties at planting time (making sure not to damage corms when installing the stakes). If your flower spikes are unsupported and breaking, it makes sense the flowers are dying, as damaged stalks disrupt the flow of water and nutrients. The plant is in survival mode, which means flower production is last on its list of priorities!

 

 

1st TIME PLANTING GLADIOLUS

I PLANTED GLADIOLUS IN LARGE POTS , W/DRAINAGE HOLES 3 MONTHS AGO ,ALL I HAVE IS 30'' GREEN STALKS,NO FLOWERS, WILL THEY NOT GET FLOWERS THE 1st YEAR?I LIVE IN DE AND EVERYTHING ELSE HAS ALREADY BLOOMED EXCEPT THEM WHAT'S UP?

when will gladiolus bloom

Your glads should bloom this year. It takes about 90 to 100 days from the time gladioli are planted to root, grow, bloom, and store enough energy for the next season. You may want to try adding some compost or aged manure to your pots.

Gladiolus Pretty Pinks

I do not have a green thumb! But I did get some Gladiolus Pretty Pinks. I was so amazed when they started coming up!! They are now almost 2 1/2 feet tall. I was worried about planting them outdoors. The Texas soil is like Mud!!! So I bought a big 14 inch pot and planted the bulbs in that, they are indoors. I spaced the bulbs apart like it said. ( 4 ) of them. There are no flowers yet, but the green leaves are so long they are drooping over!! Are they suppose to droop? They don't look at all like they are dying. But still No flowers. What can I do to avoid them drooping over. Thank you. Diane

Moving in June

I'm moving its June in Ohio. Can I dig and replant them now or will it kill them ?

transplanting gladiolus

Hi, Melissa, As noted above, it’s important to leave the foliage intact/attached, after the flower fades, to enable the plant to thrive. You should be able to transplant if you use a little extra TLC: lift the glad bulb (corm) with a lot of the soil it is planted it. Go deep for the roots, as far as you are able. Set the into a container or box. When you get to your new place, rather than replant—because you will be lifting again in fall—maintain the bulbs in the container/s. In fall, procede to store them as described above.

strange pods

Just out of curiosity, what are the strange pods that form where each blossom has been?

gladiolus

how do I trim the flower from the plant?

cutting the flower

David, do you mean to cut the stem and display the flower? If so, cut it in such a way that you have a length of stem below the last bud—you want to plant the stem into a vase with the last stem out of water. Take a sharp knife and slice the stem.

Tiny immature bulbs

Can you tell me how tiny pea- sized baby bulbs -that are separated from the mother bulb -continue to grow without roots of their own?I continue to plant and store every year but don't how they continue to mature if they have fallen off the mother bulb.

There are a few causes for color change, older corms sometimes change color over time and a couple of viruses can also cause the change. Some gardeners suggest that change in light and soil pH values also can cause color change.

Gladiolus

I am planning to plant Gladiolus corns this weekend. Will they yield blooms this year?
Also how do I stake them?

Thanks, LaNita Willis

bloom time

Your glads should bloom this year. (Nothing is guaranteed in life and in the garden—but these are relatively fail-safe.)

Stake when you plant. You do not want to do it later and risk damage to the corm or growth of the plant.

Left stalks on over winter

I got the wrong advice and left the glad stAlks on over winter. Now the main bulbs are soft and less in mass but they have many small bulbs. Can I still try planting main bulbs ???

Moving sprouted glads

Much to my dismay, I mixed up my bulbs and now my glads are sprouting in a six inch deep container where it is mostly shady...a container in which I thought I had put caladium bulbs. Now that they have sprouted and are eight inches high I am tempted to move them to a more suitable place. Can this be done?

I have transplanted glads at

I have transplanted glads at different times with varying results, but go ahead and water them freely.

Hi my Gladiolas stem is

Hi my Gladiolas stem is turning yellow. They haven't bloomed yet and u live in the high desert part of California. I'm wondering if that plant is becoming diseased? They are already in the ground.

It could be a disease but it

It could be a disease but it could also be problems with your soil and/or moisture. Glads grow best in loamy soil with good drainage. Compacted soil hampers root growth. Glads also need lots of water to develop a good root system. Make sure your plants get at least 1 inch of water per week.

Hi. I just bought some daygl Mix gladiolus and i live in west virginia w is it safe to plant them now and if so when could xpect blooming to start

Gladiolas.

I planted some a few years back along the fence and when they grew the blooms were facing the fence and not the yard. I just bought more bulbs. What's the secret to getting them to bloom in the right direction?

gladiolas

I am in northern California. I have glads that just started blooming and I want to know how to cut them to bring indoors to enjoy. do I cut just the bloomed ones and let the others on the stalk continue to grow? or will the others on stalk open up indoors?

Cut the stalk at the bottom.

Cut the stalk at the bottom. The buds open from the bottom & work their way up. The unopened buds will bloom inside. The bottom ones will die as the otgers start to open.Remove the wilted, dead ones.

Cut the stalks when a couple

Cut the stalks when a couple of lower buds have opened. The other buds will open indoors and you’ll be able to enjoy them for a long time.

gladioli in pots!! Why not

can I plant my glads in large pots

Sure, you can plant them in

Sure, you can plant them in pots. Just make sure the containers have drainage holes and use a good quality potting soil mix. Choose short to medium tall varieties and select container sizes accordingly.

Gladiolus

Planted several a month ago. Most look good but some are turning brown and falling over. Don't know if it is a water problem or disease

gladiolus mix

when saving them where can i put them when i dig them up. i only have a car shed to put things in. i don't have a basement. or can i just leave them in the ground until after winter then dig them up . put and trans plant the little ones if i get any next spring in February . and I also read that its ok to plant them in clumps close together then to have then apart in 6'' I have a small garden space and it looks better to have things close together or i'll get butter cut growing in between every thing. would this be ok

I want to plant gladioli

I want to plant gladioli along the fence line but only where the posts are. How many bulbs would you suggest that I plant per post so that it looks neat but not too bare?

how many glads?

If depends on the width/breadth/size of posts, but with that in mind three or five would be nice. Odd numbers eliminate evenness.

I have a gladiolus garden

I have a gladiolus garden that I leave planted all year, even during the winter. In southern middle Tennessee the winters are mild. I was going to move some of them this weekend but they are all growing, about 6 inches tall now, can I still move them?

Hi Susan,

Hi Susan,

You can move them if you dig carefully and get as much soil with the corms as possible. Plant them in the new spot and keep the soil nice and moist.

We dug up, moved & gave away

We dug up, moved & gave away aprox. 200 bulbs! So far all that were replanted are doing great! Can't wait for them to bloom! :-)

baby corms

When i dug up the glads last fall, I separated the new large corm from the old corm that had bloomed and stored them for winter. But I also have 100's of baby corms as well. They are about the size of a large pea. What do I do with them? Do I plant them the same way as I do the large ones or just put them in a large plot and hope they will grow into larger corms this year or next year? I don't know what to do with them. Will they grow bigger over the next year or two and then plant them in the garden and hope they will produce flowers at some point in time?

The baby corms are called

The baby corms are called cormlets and will grow into a plant. Plant the small corms in a separate area of your garden. You can space them pretty close. They will grow into small plants but will not flower this year. Dig them up in the fall again and replant the next year. Usually they will bloom the second year.

color change

Years ago I planted several colors and they were beautiful, but now they have all turned white. None are colored, what is going on?

Gladioli by a different name

I have a difficult problem that up until now, no-one seems to know answer. My grandfather used to grow what looked like common/typical gladioli. They were in the typical colors of yellow, pink, red etc. I remember him telling me that they were NOT real gladioli but had a different name - although to the uninitiated they were typical gladioli. Any ideas of what they may have been? I haven't heard the name for 40 years so I hope you may be able to help to jog my memory? Thanks!

Hello, I did a little

Hello, I did a little research as I used to work in a nursery & this question rang a bell. Unfortunately at the moment I can't think what the name of the flower is that we sold which looked like a small gladioli. I've found a small article which I've taken a part of & attached below. Good luck remembering, cheers, Shiree. Most of these hybrids are long gone, however more recent hybrids have been produced including the so-called Homoglads; a cross between Homoglossum watsonius (recently reclassified as Gladiolus watsonius) and Gladiolus tristis. Based on descriptions of some of these older hybrids, there is great potential for producing useful garden plants from these species.

gladiolus flower color

Hello. I have planted about a dozen new corms every Spring for three years without digging them up (PeeDee of SC)... just covered the ground with a few inches of pine straw that I raked up from the trees in the yard. Now that I decided to dig, I have 100's !!! of little baby corms.
Here's the question... This last Spring I cross pollinated (by hand) a white glad with salmon-pink glad. Also, I cross pollinated a white with a dark (almost black) purple. What color flowers will the seeds grow to have? Thanks!

Baby corms or cormels are

Baby corms or cormels are offshoots of the mother corm and produce clones of the mother plant. To create new cultivars and colors, you must collect seed from the seed pods remaining after the flowers have withered away. Read more at http://www.gladworld.org/Chapter%20Eleven.pdf

 

Gladiolus

I would like to grow gladiolus for my daughters wedding on Sept 3rd 2016. Is it possible to have them this late in the summer? If so, when should have plant the bulbs to ensure that that will be in bloom for the wedding?

Thank You

Hi John,It takes about 90 to

Hi John,It takes about 90 to 100 days from planting the bulbs to bloom. Glads grow best in warm weather so depending on where you live you may want to grow some in containers so that you can make sure that they get the best growing conditions as possible.

Hello. My Gladiolus were a

Hello. My Gladiolus were a Mothers Day gift from my boyfriend this year. I've had them from bulbs, and have 75 of them..They have boomed but im wondering if I just cut the stalk the flowers grow on or all the leaves as well?

Please wait and allow the

Please wait and allow the stalks to turn to the color amd consistency of the brown paper bags before removing. If removed to early, it has a tendency to effect the feeding that nature gives to the bulbs/corms during a time we believe is the ugly time. If you are concerned with the appearance, I recommend planted something that may over-shadow that until each is ready for discard. I enjoy the varying degrees of red gladioli and love adding single colors to the bunch to create different effects. Currently, I have Buck-red celosia camoflouging my glads.

This is the first year I put

This is the first year I put glads in pots on my deck. I noticed that after the flower dies a small seed pod like growth occurs where the flower was. Is this something I can use to grow new ones or is this something that should be discarded?

These are little seed pods.

These are little seed pods. Wait until they turn brown before taking them off the plant. In early spring plant the seeds in pots inside and wait until they are a few inches tall before plating them outdoors. It may take a couple of years before they will flower.

I love the gladiola flowers

I love the gladiola flowers and decided to grow them first time myself. I live in Colorado. Stalks came up and got many stems with buds but they dry up and don't open up or bloom. I have all these stocks and it's a shame the flowers don't open up. Any ideas?

Perhaps you need to put plant

Perhaps you need to put plant food in when you water them, or you need to water them more frequently?

Can you put the corms in the refrigerator over the winter?

They should be fine in a

They should be fine in a paper bag kept in the vegetable drawer of your fridge. Check them occasionally for rot and throw out any that get mushy.

I planted 30 Blue Glads this

I planted 30 Blue Glads this spring along with 30 white and 30 red. What stumped me was the fact that all 30 blue DIDNT bloom blue at all but bloomed a purplish pink color instead. My question is, could soil ph cause the color difference? If I recall with Hydrangea changing the ph will change color from blue to pink or pink to blue.

There are very few flowers

There are very few flowers that are a true blue color. Many varieties that are called blue have purple or pink hues mixed in. We don't think that the pH of your soil has anything to do with the color change. There are a few causes for color change, older corms sometimes change color over time and a couple of viruses can also cause color change in glads.

Soil ph levels for glads

In May of this year (2016), the response to this question indicates that ph level may indeed affect bloom color.

Hello! I have planted I would

Hello! I have planted I would say at least 100 Gladioli bulbs this spring! I am happy to say almost all of the bulbs flourished, flowered and are doing wonderfully! I noticed that once the flower has gone, a kind of bulgy pod starts to grow where the flower was on the stalk. What are these little pods? Do Gladioli also produce seeds? I live in Illinois. I do not know what the USDA zone is for my area. I have read that you do not need to dig up the Gladioli as long as they are protected from the frost with a layer of mulch. Should I dig them all up? Your responses are so appreciated!! Thank you!

It is handy to know what zone

It is handy to know what zone you live in when purchasing plants. Illinois is a big state and the plant hardiness zones range from 5a in the very northwest corner to 7a at the southernmost tip. Unless you live along the Kentucky border your winters would probably be too cold for your glads to successfully winter over in the garden.
Glads do produce seeds in those pods. Save the seeds and try planting them next spring. It will take several years of digging and replanting the corms before they produce a corm large enough to blossom.

Thank you! It was a

Thank you! It was a beginner's mistake not to know my own hardiness zone. Now it is something I MUST check before purchasing. I am a novice gardener, this being my second actual year of gardening. I live in Zone 5a, so now I realize how much work is involved with the amount of Gladioli I have. I have to dig them all up. I will most likely end up selling them because they are healthy and robust but cannot survive the winter in the ground in my zone. It's a little too much work for me. Ive purchased some new bulbs for fall planting to replace the Glads and made sure they were hardy to my zone. I bought some Lycoris Squamigera, the most cold-hardy of the Amaryllis family! So excited for these so called "naked ladies". Thank you for the advice! I appreciate it.

I bought a lot of spring

I bought a lot of spring bulbs this year. However, I never got around to planting them. I have glads, calla lillies, lilly of the valley and spring mix bulbs. Have I lost them all. Can I plant them now? Help! What should I do??

If you live in a region with

If you live in a region with cold winters you can plant the lily of the valley and any spring-flowering bulbs (tulip, daffodil, crocus etc.) in the fall. The glads and calla lily bulbs will not survive freezing temperatures. If the bulbs look OK you can save them and plant in the spring. The calla lily bulbs can be planted in pots and kept indoors during the cold months.

Hi everyone im wondering if

Hi everyone im wondering if someone can help. Ive grown a around thirty gladioli this year and many have grown really well, most around 4.5ft high. Ive just recently cut the flower stalks and all is well,however ive come across 3 seperate ones that have grown 2 flower stalks. A pink one has a small secondary sstalk consisting of 3 flower buds, a green one with 5 flower buds which is much thicker/longer and a pure white one that has 6flower buds. I suppose im wondering is this normal as i havent read anywhere suggesting it is or could be. And could i take some special measures to take extra care of these 3 once pulled? Thanks for any help guys.

A few of my Gladioli had 2

A few of my Gladioli had 2 flower stalks also!! I found one orange and yellow one that produced 3 stalks!! I would say it should mean our plants are healthy and doing well. The flowers, produce the plant's pollen which allows them to reproduce. It could be that these Gladioli of ours will make tons of baby bulbs this year. Also, pruning is healthy for the plant. I was cutting the stalks off once the flowers faded. Pruning promotes new growth with most plants. Maybe this is why some of them grew extra stalks?

Thanks for the info. Ive

Thanks for the info. Ive found with mine that the secondary stalks had already grown an inch or so by the time the first flower had bloomed, either way im happy :) my partner has already dug some up as theyve started to go brown and weve a solid 40 babys already, only another 20 more to pull up (healthiest ones to)

Awww, 40 babies already! That

Awww, 40 babies already! That sounds great! I made the mistake of not knowing about "hardiness zones" before purchasing the 100+ Gladioli bulbs I planted this past spring. I have to dig them all up in a few days because I live in Zone 5a. I think I will be selling them online because they are too much work for the quantity that I have. They made tons of babies that I haven't even counted yet! I can see them popping up through the soil. They were absolutely Gorgeous Glads! They attracted butterflies, hummingbirds and an array of Moths but I cannot keep all of them. Plus the North side of our house is very shady and AGAIN, I made the novice mistake of planting bulbs there that need full sun (the Glads) so either way I have to dig them up. I am replacing them with Hosta bulbs I purchased on ebay. Now I feel much more informed and educated about the different sun requirements, soil requirements and hardiness zones! Thanks Kristy!

Hi. Zone 9 Phoenix, AZ. My

Hi. Zone 9 Phoenix, AZ. My Glads bloomed well in late spring/early summer in containers. I'm wondering if I can plant some annual, summer blooming plants in the same containers like Vinca after the Glads have died back--my concern is if watering the summer blooming Vinca would rot the Glad corms or the new plants would damage the Glad corms lying below in the container?

Should I just dig up the Glad corms to be safe before putting in other summer annuals even though the Glad corms can last in the containers in this zone?

You can plant some

You can plant some shallow-rooted annuals on top of the corms if your containers are deep enough and have good drainage. If you water only when the soil is dry the corms will be fine. Don't remove the glad foliage until it has turned brown.

Luanne, you should remove the flower spike after the blooms fade but leave the plant's foliage. Continue to water and weed. When the foliage fades and dies (turns yellow), lift the corm for starage and cut the stem/foliage back to about 1/2 inch from the corm.

Hi, sorry if this is

Hi, sorry if this is redundant!! I live in Southeast Idaho & I'm very new to gardening. My landlords are what I call 'Flower Nazi's' so ALL of my flowers are in containers. Do I need to remove the corms from the containers or just simply put the containers in the basement? Thank you!!

Hi, Raven, You would normally

Hi, Raven, You would normally lift the glads from the ground in autumn, so lift the glads from the container soil. Procede with storage as directed above.

I bought some glad bulbs two

I bought some glad bulbs two years ago and forgot to plant them. Last year I found them and planted them (so they were a year old), but they have not come up at all. They had been stored in the mesh bag that they came in, but had been in a cupboard above the washer and dryer in the laundry room for the year after I bought them. Should I just dig them up and forget them? Or should I wait and see if they come up this year? The glads I had previously planted are already up and I am just waiting for them to get flowers. This usually happens after my lilies bloom, which is happening now. Plus everything has bloomed earlier than normal this year. I live in Washington State.

I also found some bulbs that

I also found some bulbs that I forgot I had that I put away. They were in a mesh bag as well as being in a box. When I opened the box the bulbs were very dry. I placed them in some water thinking that perhaps this might help to put moisture back into the bulb. I did this & went back to them & found that they were not going to be able to grow. So I went & purchased more bulbs that were planted & grew with some beautiful flowers. Now the flowers are going away & I can hardly wait for next year. Toss those other ones & try with a new purchase of bulbs. The results will be a purchase you will be glad you did.

I like to say that I plant

I like to say that I plant Gladiola 2 years ago and I still have my Gladiolas The blossom every year rain,snow and I have them every year ,but one think I do I pray for my Gladiolas to come outevery year,I am bless.I put mulch every year and water.thank you for the info I leaner that I need to take out the dry flore to be come more,THANK YOU.

Good question. Glad grow from corms--which are bulb-like structures. So I guess you could say that corms and bulbs are one and the same for gladiolus. Corms need to be at least 1 1/2 inch in diameter to produce blooms, no smaller. If you plant between mid-May and mid-June, you'll have flowers blooms July to August.

I live in South Florida and

I live in South Florida and our summers are pretty wet. If I do not dig up my glad corms will I have issues with them coming up next spring? Will the damp, wet soil contribute to disease or some other malady?

I saw your comment/question, but don't a reply. I live in the Tampa area and I am brand new to Glads. I grew mine from the bulbs I bought in a store and they have done well!!! I just don't know what am I supposed to do after they have finished blooming their first time?!?!?!?

I live in SC. I planted my bulbs about 3 week's ago. The sprouts were 8 to 12 inches tall. The dog dug in my flower bed and broke off a good many of the sprouts. The bulbs and roots were undisturbed and are still rooted well. Will the bulbs sprout again?

Hi! Newby gardener here. I

Hi! Newby gardener here. I have some gladiolus bulbs that I plan on putting in a flower bed pretty soon here. I have a few questions:

Can I lay mulch down once the bulbs are planted? Meaning, will the plant be strong enough to push through the mulch (1-2" of mulch)? The bed where I will be planting them had quite a bit of weeds in it already so I have gone through and gotten those out. My concern with planting the bulbs and waiting to lay much until they're above ground is that the weeds will come back.

Second, what other flowers pair nicely in a bed with gladiolus? Again, newby here, so I'm not sure what to plant with them.

Thanks all!!

Add a thin layer of mulch

Add a thin layer of mulch after planting the bulbs and then when you see new growth add some more mulch. Any low growing or medium height annual flowers will grow well with glads. You could also plant some herbs among the glads.

After planting my Glad corms

After planting my Glad corms and water them for first time do I keep watering them or wait for them to sprout up before watering them again. Don't want to water them so much they rot.

Water immediately after

Water immediately after planting, but then not again until you see growth. :)

Hi
Try to remove the bulbs well after the flowers will be gone. Store in a cardboard box as any other location. At the same time - plant second batch to have flowers after the first one is gone. If needed - try third batch etc.
This way you can have steady supply of flowers and healthy bulbs for next seasons, Good lack

Hi, John, These minis,

Hi, John,
These minis, identical to the mother in color and flower type, are also called "cormels." The most promising ones are the zie of a dime or larger. Before planting, soak them in water for one day. Plant them 2 to 3 inches deep, and keep the soil most until plants emerge.

There were beautiful glads

There were beautiful glads planted in the flower beds when we bought this house in May- 2014. They bloomed all summer, and because I live in SETX I left them in the ground. They are coming up like crazy, I have nice foliage but no flower stems yet, so my question is... They are planted just here and there, (a total of about 30) and I would like them all in one place for a better show... Can I dig up the ones I want to move now, (Im the kind of person that likes instant gratification) or should I just purchase some new bulbs and plant them where I want them? Thanks for any suggestions!!!

Hi Rebecca, Don't transplant

Hi Rebecca,
Don't transplant the growing glads now. Wait until later this summer or early fall to dig up and divide the bulbs and then replant them where you want them to grow. You can buy new bulbs now to plant in the new garden spot.

Hi, Len: 1. No ... er, well,

Hi, Len: 1. No ... er, well, maybe ... sometimes darker corms indicate upcoming blooms in darker shades (same for lighter/lighter). Note: Sometimes. 2. No. Well, soil conditions and disease can sometimes affect color, but it would be tough to do this in a predictable way. "Glad" you asked!

I have planted some gladiolus flowers and I noticed that there is red bulb looking things and what do i do with them do i preserve them?

These are little seed pods.

These are little seed pods. Wait until they turn brown before taking them off the plant. In early spring plant the seeds in pots inside and wait until they are a few inches tall before plating them outdoors. It will take 2 to 3 years before they will flower.

Thank You

Good question. We have never

Good question. We have never had problems with our glads and have planted them in the same garden year after year. However, according to some experts: To avoid gladiolus diseases, you should practice "crop rotation" if possible, planting glads in different locations from one year to the next.

I planted glad bulbs in pots

I planted glad bulbs in pots this year and the leaves were straight as an arrow and very tall but they did not flower. I did some last year as well in a flower bed with iris and hostas but some of them only flowered small flowers. I was wondering what I could do to get these to flower next year. I was not going to dig them up just leave them in the ground this year so they could multiply. I live in Maryland close to the Chesapeake Bay.

Hi, Mark: Seven years. :) ...

Hi, Mark: Seven years. :) ... But seriously: Glads reproduce underground. If you have been pulling out your corms each fall, you should have been gradually discarding old corms for newer ones. But it sounds like you have been leaving them in the ground, so assuming that they somehow have not been subject to some new killer frosts, what most likely has happened is that they are now just overcrowded down there. Dig up the corms at the end of the season and keep only a reasonable number of newer ones for next year. Thanks for asking!

My glads are only on second season and this year NO flowers!
Any ideas?

Make sure your glads get enough sun and are well watered. You may also want to add a little compost to the soil for extra nurishment. Don't cut the leaves at the end of the season. Let them turn brown and then remove them.

i love the looks of glads when you stake them. What is the best way to do this? What should I use for the stakes?

Hi, Perry: We're "glad" you

Hi, Perry: We're "glad" you asked! Use just about anything that's tall enough and cheap! Tomato stakes, driveway marker stakes (such as to show where to plow), PVC pipe, sections of volleyball net poles, sections of other poles (such as roof rakes), or just plain ol' strong straight sticks/branches -- we've used them all (and more)! (And tastefully, too... or so we've been told.) Tie the glads gently with string or fabric strips. Remember that you can "stake" a small clump by lassoing it with string tied to one or two stakes. For a straight row, one string between two stakes. Beautiful!

hello, I thought I would

hello, I thought I would share with you a trick that I learned. I grow Maximilian perennial sunflowers and Hardy Hibiscus. Both leave tall, straight, dry stems throughout the winter. In the spring I cut them and save them for staking my dahlias, delphiniums, and gladiolus. They are free and tough. My stakes range from 4 to 6 feet in length. They are perfect. sincerely, constance

After overwintering, will the

After overwintering, will the blooms be simultaneous?

I planted several batches about three to four weeks apart, and I intend to overwinter them in the ground (8b with Texas heat). I'm concerned that staggering my planting will not do me any good when they rebloom next season. I wanted a continual show each season - will they bloom staggered or all at once, in ideal conditions?

If you stagger your plantings

If you stagger your plantings through late spring and early summer, you can have glads in bloom from June through September. It's a good idea as the plants only stay in bloom up to two weeks.

I was given some glads bulbs.

I was given some glads bulbs. Is it to late to plant? I live in West Texas. Thank you

In Texas, many people plant

Is Digging Up Necessary? I

Is Digging Up Necessary?

I never dig up the corms and they spread prolifically. But I do cover them with oak leaves from a nearby tree over the winter, to protect them from winter snow, ice and any salt used on the nearby sidewalk. These are removed in early spring. Last winter (2013-14) was the worst winter we've had in 20 years. But this spring my glads are going crazy. The only other thing I did was add lime to the soil to balance the pH prior to adding annuals.

I second this comment. I live

I second this comment. I live in central Indiana (zone 5) and have been growing glads without digging them in the winter for years. I thought last winter might set them back but they are doing better than ever this year. And I don't even mulch them. Granted, they are not the newest varieties, but they are also not any of the ones that I have seen listed as "hardy". They are normal looking glads with colors ranging from white to pink to striking magenta.

I live in Michigan (zone 5)

I live in Michigan (zone 5) and I don't dig my glads up either. They are in a raised bed and even after our harsh winter they are going crazy, making "babies". I want to dig and sell some of the bulbs through my nursery but not sure when to dig them. Can I do it after they are done flowering and just not cut the stalks. Then should the customer let them dry over the winter and plant next spring or go ahead and plant this fall? Thanks!

Hi Natalie, It's better to

Hi Natalie,
It's better to plant the corms in the spring. Dig the glads after the tops have started to turn brown and before the cold weather sets in. Don't remove the stalks and store them in cool dry place over the winter. In early spring remove the stalks and sell the corms.

I live in Austin which is not

I live in Austin which is not nearly as cold as Michigan. Do you cover your plants if it comes a hard freeze? I'm reading that you should plant after frost but what does that do for the bulbs that are overwintered?
thanks...carla

My gladiolus flower buds are dying. I live in Ga, zone 8. The flower buds have turned black and died before they started blooming. Any idea? Could it be that I applied some humus fertilizer around them and watered? I bought the humus fertilizer from Walmart, at < $2 for a 25 pound bag.

Hi, I am in North Carolina,

Hi,

I am in North Carolina, and planted a row of Gladiolus in a front bed that receives plenty of sun. I planted about 5 - 6 inches deep as per instructions. Now that they are starting to bloom, I see that the flower step gets really wilty during the hot days. I find myself watering a lot because of this and am afraid I may be overwatering. Is the wilting normal, and should I water daily?

Regards,
LRoyal

If the plants look healthy

If the plants look healthy otherwise (no discolored or pale leaves, stunted growth, curled leaves, evidence of insects along the stem or under leaf or flower surfaces, etc.), then likely it is just the hot weather. Provide an inch of water per week in normal temperatures, more when it is hot. Check the soil each time you plan to water--if it is soggy, do not add more; it the top inch of the soil is dry, then provide more water. You might also try giving the glads temporary filtered shade (such as via a burlap screen) during the hottest part of the day if it is especially warm.

How long does it take for

How long does it take for glads to come when planted by seed? The seed was to be planted like radishes,, I did that,will they form a glad bulb first to take out in the fall? will they show any sign of a growth on top of the ground, or do they only form a bulb to be dug up in the fall and planted the following year?

It will take 2-3 years before

It will take 2-3 years before they will be big enough to flower. You will see some green tops growing this year and you need to dig them up this fall if you live in a cold region. Keep them indoors over the winter months then bring outside next spring. It's recommended to start seeds in trays or pots for easier germination.

I live in Massachusetts & have been gardening for which seems like forever, May question is how do you boost your gladiolas to bloom? Im having a hard time this year. Open for a suggestions.... thank you

Glads need at least 6 to 8

Glads need at least 6 to 8 hours of sun and well drained soil. Adding compost or aged manure to the soil will help the bulbs grow bigger and produce more flowers.

Yesterday (06/19/2014) I dug

Yesterday (06/19/2014) I dug up several of the Gladiolas that my Grandmother had set out 25-30 years ago. There were some blooms and several old blooms on the stalks. I tried to get the whole area of plants so that my chances would be better of getting a stand of Grandma's heirlooms.

Her farm was in Alabama (clay soil) and I am in Florida (sandy soil). What do I need to know about helping these plants to survive now? Prune the stalks when transplanting? Divide the corms (?) to propagate?

Any advice would be appreciated.

Before you plant the glads

Before you plant the glads amend your sandy soil with some compost or aged manure. You can cut the flower stalks but leave all the leaves intact when transplanting. This is a good time to divide the corms. After 25-30 years in the ground you'll find that many of the corms have mulitplied.

I live in mid Atlantic. This is my first year of planting it. Only about 65% seem to grow up now. But the biggest problem for me is some of the leaves (corm?) seem to fall down and bent as they grow taller. (And frankly, I don't see any sign of it to bloom.) Any suggestion or advice? Thanks in advance.

I live in Houston, Texas and

I live in Houston, Texas and planted my bulbs late february/ early march and they are doing great! They bloomed last week but the flowers on the lower part of the stalk are already withering and dying. Do I dead head them or leave them? Will they bloom again or after they all wither up, will they be done for the year? This is my first attempt at flowers altogether but so I don't know what I should be expecting. Thanks!

Usually glads have one stalk

Usually glads have one stalk with flowers and as each flower fades you can remove them. When all the flowers have faded you can cut the stalk. Leave the leaves on the plant until they turn yellow. Sometimes a corm, if it is big enough, can send up another stalk.

You need to water when the

You need to water when the soil feels dry. Glads don't like to sit in wet ground. You may have a blight issue or corm rot. See the link below for more information about diseases.

I don't understand this. I've had these flowers for the last years. Never a problem. I never ever dig them up and they do multiply each year.

The are carefree plants. I think most people put too much emphasis on digging them up in the fall. I also plant new bulbs as late as June and they will still bloom. I live in Cincinnati Ohio and the ground does freeze here. Same thing with Lilly's and iris here. Carefree!

Hello! I live in Illinois.

Hello!
I live in Illinois. Zone 5 and 6 I do believe. I planted Gladiouls in April (2nd to the last week of) and they are growing. The stems are long but are drooping over. They get full sun, well drained. Some stems are turning like a whitish brownish color. Does this mean they are dying? I am going to replant them in the ground when we move in June. They are in pots well drained now inside. I do set them outside in the daytime south facing where the sun comes in the most.

Thanks

It sounds like your gladiolus

It sounds like your gladiolus may have botrytis. Immediately remove the infected stem/leaves. To avoid this fungus from spreading, do not water from overhead, rather, water it at the base.

Can I plant small corms and get flowers

If the corms are tiny plant

If the corms are tiny plant them in containers to grow bigger. It may take a couple of years before these flower.

I planted my gladiolus bulbs

I planted my gladiolus bulbs 12 inches deep before reading it should be about 6 inches. Will it still bloom properly or should I replant them?

If you just planted, we'd

If you just planted, we'd re-set the corms 4 inches deep. Otherwise, we've never tried 12 inches so it's an experiment! 

In NY I always plant my glads

In NY I always plant my glads 12" at a minimum in well draining soil. They grow 6'+ tall on average and need this depth to support the plant in addition to staking support. Additionally, this protects them from the frost / freezing. At this depth I also till the upper 4 to 6" each year by hand to loosen up the soil, carefully though as I have found new bulbs a few inches above the original ones planted. Mine reproduce like rabbits ... or potatoes ... and the average new bulb size is 3 to 4" in diameter. After tending the soil in the spring, I cover with another 2-3" of mulch to keep the weeds down and the soil moist. This works for my area where we have hot and humid summer months.

I live in Belize, Central

I live in Belize, Central America and I have planted Gladiolas for the first time. I planted them three to a pot and set them in my fridge since Belize is so hot all the time. They have sprouted already so how soon can I put them in the ground, and will I have to take them up after they bloom and perhaps store them in the fridge until next year or could I just leave them in the ground all year long?

I doubt you need to keep them

I doubt you need to keep them in the fridge. I live in Georgia and my Gladiolas live outside all year around. It gets very hot and humid here.

I would plant them outside in an area where the soil drains well.

The corms (that is the seed) stay in the ground here in Georgia over the winter because it doesn't usually freeze. If the ground 'Hard' freezes it will kill them.

They don't like to sit it wet soil. They will rot. So, if you have a lot of rain make sure the area you plant them is not heavy clay type soil and that the area doesn't stay 'sopping wet' because it drains well.

It gets to be over 100 degrees here and my Gladiolas are in full sun most of the day. I do have to water them sometimes if it hasn't rained.

The winter weather here is generally cool with some freezing days (not long enough to freeze through the ground.) I do cover the ground above the Gladiola corms with a heavy layer of mulch after I cut back the leaves yellow. Leave the leaves alone until they yellow because they are storing energy for next year's crop.

I hope that helps you. Gladiolas are beautiful! I love to cut the flowers and show them off in a gorgeous vase.

In Texas, many people plant

In Texas, many people plant gladiolus as early as mid-February but you can usually plant through the end of April. 

Hi Carol, I would plant them!

Hi Carol,

I would plant them! They may need to be staked later when they are tall and heavy from the buds/blooms.

It can be really windy in TX so finding a less-windy spot in your yard would help.

If you have clay soil be sure to prepare the soil with compost, manure, top soil, bone meal; something to enrich it and loosen it. Gladiolas prefer to be well drained.

It takes about 90 days from planting until they bloom. You can plant some each week to stagger the blooms so you can enjoy them longer.

I love Gladiolas! Apparently they are an 'old' flower and aren't the 'in' thing ... buy oh my goodness... They are GORGEOUS!

I remember seeing Gladiolas

I remember seeing Gladiolas on my grandfather's farm in Iowa. My mother showed me how you could pull off the blooms and make a little doll. We just tilled up an area and put in miracle grow garden soil and lava sand.

Thanks so much for your information!!

There are a couple of

There are a couple of heirloom glads that you can leave in the ground and grown as perennials in Texas, but most gladiolus corms should be dug up after the foliage has dried in late summer or fall if you wish to save them for next year. See above information.

I live in arlingron tx. you will need some patient to see your first flower on the glads. the stem itself will reach about 2 to 3 ft before you begin to see the actual stem for the flower shoots. you shouls see then bloom in about may or early summer.enjoy!

Vino, I wonder how your Glads

Vino,

I wonder how your Glads are looking now? Mine have grown a lot in the last week! I sprinkled them with some fertilizer and I really think they like it!

It may sound crazy - but I am looking forward to the fall so I can dig them up and separate out the new corms! I will take that opportunity to really improve the soil as well.

We have Georgia 'Red Clay.' I am planning to add in manure, bonemeal and maybe some compost soil to enrich the beds. I am hoping for a 'bumper' crop of Glads next year!

Also ~ If I want the baby

Also ~ If I want the baby corms to multiply ... When should I dig up the bulbs to separate the baby corms, spread them about, and replant them?

I planted Gladiolas and this

I planted Gladiolas and this is their third blooming year. I expected them to multiply ... but there are fewer than last year all ready. I live in GA so I don't have to lift them. It seems odd to me.

Should I dig them up and see if there are any baby corms? If there are baby corms ... should I move them around? Should I add peat moss or other items to the soil to loosen it up or feed?

I had Glads when I lived in the Pacific Northwest and they just do great on their own. So I thought for sure they would love it here!

Wait to dig the gladiolas

Wait to dig the gladiolas until they have bloomed and the leaves start turning yellow. Fertilize your gladiolus three times a year for bigger corms, when planting, when the stems are about six inches tall, and when the flowers begin to fade.
Each glad will produce one or two large corms and several small corms. Break the new corms off the old corms and plant the ones that are larger than 1/4 inch in diameter. These may bloom the first year. Add some compost or aged manure to the soil. Plant the tiny corms in pots until they are big enough to go into the garden.

I live in florida, and i was

I live in florida, and i was wondering if i have to dig up the gladiolus before every winter it usually doesnt freeze around here.

You only need to dig up glads

You only need to dig up glads in the north of Florida where you get frost. According to University of Florida Extension, corms should be dug up, dried and stored at 40 to 50 degrees F for next season when foliage begins to yellow.

I planted gladiolus bulbs for

I planted gladiolus bulbs for the first time this year - live in northern Minnesota zone 3. The leaves have come up, but no blooms. Does it take a few years before blooms will come? I was so disappointed and also we were disappointed that we have to dig up the bulbs and replant again next spring! Especially since we had no blooms this year after planting 60+ bulbs! (or I guess from reading your info above, I should call them corms) As you can probably tell, I am a novice gardener as far as gladiolus flowers are concerned. Thanks for any suggestions you can provide!

Hi Jan, Your gladiolus may

Hi Jan,
Your gladiolus may still bloom this year. When did you plant the corms? If you plant the corms in late spring when temps have warmed up a bit they usually bloom in mid-summer.  If you planted them later they will bloom later. Also make sure that they get enough sun.
 
 

I live in Lubbock, TX, Zone

I live in Lubbock, TX, Zone 7B. When flowers, such as Glads, say full sun, how much heat can they usually stand? I realize that it probably a difficult question, but my west facing garden would be a beautiful place for my Glads but I'm afraid the heat from the brick would be too hot. Please advise. I am new at Glads in Texas. Beautiful in Florida but.......

Don’t confuse sunlight with

Don’t confuse sunlight with heat. Gladiolus need about 6 hours of direct sunlight. Assuming you’ve got that and other proper conditions—rich, well-draining soil into which you set the corms 4 to 5 inches deep and 5 to 6 inches apart, water well when necessary, and stake against the wind, if necessary—you should have no problem.
A west-facing spot does not typically get the direct sunlight of a south-facing spot, and so is usually not as hot, certainly not for as long as a south face might be. Be sure that your plants get the amount of sunlight they need.

Why do my glads grow well

Why do my glads grow well with buds but do not blossom, they turn brown and dry up.

i have 3 colours of glads

i have 3 colours of glads under my living room window facing west. the 6ft purple variety usually blooms first followed by the 4ft pinks and finally the 4ft orangey yellows. I didnt realise they grew quite so tall & would fall over but staking is difficult as the soil near the house is quite shallow. So i have resorted to propping the base of the stalks with bits of broken bricks. It works for me ! =)

Kindly advise how to speed up

Kindly advise how to speed up blossoming.

I live in the Sikkim

I live in the Sikkim Himalayas. I planted around 30 corms of gladsearly this year in February. They ALL gave me some pretty lush foliage but only 13 flowering stems. "Lots of sunshine" is a bit of a problem because March onwards we have lots of rain and very little sun. they did give me some really pretty blooms though. What can I do to get all y corms to flower? and is there any way I can know what colour the flowers will be from the bulbs? Most of the bulbs I have are all purchased from the local gardener.

Will gladiolus grow inside

Will gladiolus grow inside during winter months?

Yes an option here would to

Yes an option here would to plant in the dry season when you do have lots of UV and sunlight. As they take three months to bloom you need to time it correctly. Start planting one or two month before the beginning of the dry season. This will give you plenty of sunshine. Gladiolus can be planted at anytime in warmer climates in yours you need to time it so its not overcast all the time or too cold. Cool weather is fine around about 23- 25 is optimal for their growth and flowering in fact. Find those optimum months of sunshine and you are away. (:

I've been replanting my glads

I've been replanting my glads for years and have always had really good luck with them. This year the flowers formed and started to open but when I would bring them in they didn't open further. Could my bulbs be diseased? I'm wondering if I should bother digging the bulbs up this fall or just purchase new bulbs in the spring and start over. They are planted on different ground each year although the same side of the garden. Do I need an entirely new spot or is this enough rotation? Thank you for your help.

If the flowers aren't

If the flowers aren't opening, it's probably thrips, tiny insects that overwinter on stored corms. Those affected may not survive at this point.
When you store your corms over the winter, make sure the temperatures are between 35° and 40° F so that thrips will not survive.
Try dusting stored corms with carbaryl, shaking them in a bag with a small amount of the dust (just 2 teaspoons per hundred corms).

this is my first time at

this is my first time at growing Gladioli I have deep red purple with freckles of white on the bottom petal they are so beautiful and now 2 whites are flowering so I'm hooked.. now I know the beauty of the flower I'm looking to next year..... Desman Rare.. port lincoln .. south australia 5606

I have gladiolus. I live in

I have gladiolus. I live in western Maryland, my gladiolus were planted by the person who lived here before me and I've never dug them up. Can I cut the leaves back in fall? The jumbles of leaves everywhere look messy.

It is advised to dig them up

It is advised to dig them up in your area or the winter will eventually do them in. See this page for more information.

Hi, I want to know when is

Hi, I want to know when is the best dates to dig up gladiolus. I live in Unicoi, Tn. That is in East , Tn. I am wanting to dig them up. But I am not sure when. I know in the fall.

You are correct to dig up

You are correct to dig up glad in the fall if the ground in your yard freezes. There are some folks in your area who will leave them in, but dig them up if you do not want to  take risks.  Lift any time that you are 4 weeks past the bloom but before the tops turn brown. Cut the tops off the bulb and dry in a warm well ventilated place for a few weeks.

Howdy neighbor, I live near

Howdy neighbor, I live near Alcoa, about 128 road miles from you, but much closer as the crow flies. I am in Plant Hardiness Zone 7a and the average first frost for me is Nov 1-10, but since Unicoi is in Zone 6b yours seems to come earlier, around Oct 11-20. After the glads foliage turns brown and becomes dormant, but before your first frost, you need to get those glads (and any other tender roots such as cannas, elephant ears and caladiums) dug up, dried out, packed away in something like peat moss and stored in the basement. Set them back out after the last frost, which for Unicoi is about May 1-10. Last winter (2012-2013) I left my glads in the grown with the intention of sowing wildflowers in that spot in the spring. I counted on the glads just dying and going away, but to my surprise the arose and bloom the following summer. What worked for me may not work for you. Unicoi is pretty close to Roane Mtn while my home is across the road from Ft Loudon Lake backwaters ... quite different topographies. Good luck, lenewoo. Warren

I live in southern MI and was wondering what happens if I do not dig them up and just leave them in the ground during the winter. I do trim the corm off in autumn before frost and freeze. Will they come back up in the spring? Will they be ok during the winter?

In your zone (6): unless they

In your zone (6): unless they are an especially hardy variety, the average glad will freeze and won't survive. If they do, they'll be spindly and small and winter will eventually do them in. Dig 'em up! See this page for instructions.

I live in Nova Scotia. In

I live in Nova Scotia. In the spring I planted 50 glads. Most of them grew leaves that look healthy and a few produced buds but only one produced flowers and they were small, brownish and deformed. They were in full sun, I watered them regularly. My Dad grew glads for years and they were trouble free - what have I done wrong?

Gladiolus are late

Gladiolus are late bloomers--often September.  Are the stalks thick when you run your hands up them; if so, that a good sign. Are they getting lots of sun and warmth? Is the soil nice and light and not too compact or heavy? Do you see insect damage? There are some diseases that would cause glads not to bloom. It always helps to apply fungicidal sprays during the summer to protect your glads; speak to your garden store.

Hi Nan, I also live in NS and

Hi Nan, I also live in NS and have had the same issue in the past, I think from the heavy clay in the natural soil here. Any bulb hates too much water and clay retains alot of water. I replaced our soil with triple mix and haven't had this issue since. :) Good luck.

what are the buds that appear

what are the buds that appear after the flower drops ?

The buds that appear after

The buds that appear after the flower drops of are little seed pods if you leave them on there wait until they turn brown then take them off. In Feb plant the seeds in side and wait until they are a few inches tall and there is no danger of frost then plant out side. They will take 2-3 years before they will flower.

I pulled up some glad bulbs

I pulled up some glad bulbs that had been in the ground for several years. Some bloomed, some did not. Some of the bulbs have small white "attachments" on the bulbs. Are these new bulbs or a problem. How do I handle them? I want to transplant the bulbs. Thanks,CLaire

New gladiolus corms form

New gladiolus corms form immediately above the
old corm. You may see small corms called cormels form around the base of the new corm. Follow our instructions on this page for digging up the glads.

We moved to Costa Rica, the glads are big and beautiful, can I leave them in year round or should I dig them up after they bloom, also do they bloom more than once ?

I live in zone 6 and wandered

I live in zone 6 and wandered if I have to pull my Glads. They are planted on the south side,against the home, and in full sun.

According to the U.S.

According to the U.S. Department of Agriculture, you do want to lift gladiolus in zones 7 and below. This is our recommendation, too. However, we've had readers in zones 7 and 6 who did not lift them and found that their glads returned and bloomed! It really depends on how much insulating snow cover they get and how warm the winter is. (This year, our prediction is colder-than-normal.) If you don't lift them, be sure to use lots of fluffy mulch such as straw, hay, oak leaves, etc.

After moving into our new

After moving into our new home and working in my garden, I discovered a group of glads suffering to grow in a very shady area under a big tree. They had plenty of green but struggled to bloom (just got some bud-looking flowers on them.) I dug them up and want to replant them, but it is July; we are in zone 10 (so Cal.) I have prepared a bed for them, but don't know if I need to store them like in other zones or can I plant them? Store them? Please advise and thanks in advance. Donna

Your glads may suffer from a

Your glads may suffer from a fungus called Botrytis gladiolorum. Have you had a wet warm summer?
To treat this  fungus you may need to use a fungicide and discard any corms that are infected. It's also important to plant any new corms in a different area of you garden.

Hi in warm and wet summer

Hi in warm and wet summer type climates you could try the following that works. Never let the bulb come in contact with organic material compost or organic fert like bone meal. When this rots it damages the bulbs. Instead dig your beds and add the organics and fert then plant in a six inch or more layer of pure heavy garden soil on top of this., sandy soil is fine too just nothing that can break down. This keeps the bulbs clean and they won't rot. Even a layer of crumbled clay will work? In the growing season it's not so much moisture that is the problem but fungus and pathogens in rotting material. In the wild these grow in seasonally wet areas often in heavy soil however it dries up bone dry during the cool season. So out of growing season keep the soil as dry as possible don't water by mistake they need a good long dry season. Wet and cold soil will cause rot and pathogens making for diseased shoots in the wet season as will rotting organic material in contact with the bulb in the growing season.

I live in Indianapolis (zone

I live in Indianapolis (zone 6a). I have 300 glads that bloom every year. I always dig up and overwinter the corms in beds with northern exposure. Those with southern exposure usually come back on their own in the ground. I just purchased a deeply discounted bag of corms (late July). They appear to be in good condition. I know it is too late to plant them. Will they be ok next spring if I just put them in the refrigerator NOW, much like I do in early November with those in my garden?

The corms should be fine for

The corms should be fine for next year. Just store them in a dark cool place.

I live in west central Florida. When should I plant? How far down should I cut the stalk when I want to harvest the flowers?

You can plant glads any time

You can plant glads any time during the year in Florida. Cut the glad stem as long as you want for your vase but leave the leaves on the plant.

Yes leave at least three

Yes leave at least three leaves, this will ensure the plant continues to grow roots and feed the bulb to make a nice plump one for next year. If you want a very long stem on your cut flowers this will mean you set back the bulb considerably and need to buy more for next year.

It is almost August here in

It is almost August here in Central PA - Zone 6 - and I still haven't had time to put my glads in the ground. They are still in the basement from being dug up last fall. Is it too late for this year? Will they survive another winter in the basement and perhaps be fine next year?

It is a bit late to plant the

It is a bit late to plant the bulbs now. Save them for next year. Check the bulbs to make sure they are nice and dry. Throw away any that are soft or moldy.

I live in zone 8/9. My Glads were beautiful and very tall. They bloomed early summer and now are just dying stalks. Should I cut the stalks now? Or should I pull the corms and put them in the fridge till next spring?

I live in zone 7 and never

I live in zone 7 and never lift my glads. Yes, you can cut the stalks back now if you wish. I wouldn't bother lifting them at all, but if you insist, wait until fall. They might actually fool you and rebloom this season.

If I cower bulbs from frost

If I cower bulbs from frost by putting green house sheet.it can be safe then ?

We're not sure what material

We're not sure what material you are considering as a greenhouse sheet. Ideally, a breathable fabric is best, such as burlap, bedsheets, row covers, newspapers, a light blanket, etc.; remove the fabric during the day when temperatures warm up enough (most fabrics don't allow enough light in, so you'll need to remove them during daytime.)
 
 You can use clear, flexible plastic, but it will encourage condensation inside, which might freeze during the night, and any plant part that is touching it (use stakes etc. to prop up the plastic so that it doesn't touch the plants); you must remember to remove it during the day or temperatures inside can get too hot for the plant. The same goes for a cold frame or similar--open it periodically during the day to allow air circulation and condensation to escape.
 
Frost protection is needed for an unexpected late spring frost, or an unexpected early fall frost. However, if you live in USDA hardiness plant zones 6 and colder, you should dig up the corms in fall for winter storage; gardeners in Zones 7 or warmer can instead cover the area with a thick layer of straw or similar to provide winter protection, leaving the corms in the soil over winter.

my plants come up every

my plants come up every year...leaves are great, but the flowers are small...look deformed..what can I do

Hmm. There are insects, such

Hmm. There are insects, such as thrips, or diseases that can cause deformed flowers, but usually there are symptoms on the leaves as well. Do you think it might be a nutrient deficiency, such as calcium? For more information, you might be interested in this report:
 
http://ufdc.ufl.edu/UF00067646...
 
It says that a calcium deficiency, which doesn't often show up in leaves unless severe, can affect the flowers, and in certain cases, the petals may curve in, and there might be water-soaked spots on them. The flower spikes may look twisted and, if used as a cut flower in a vase, may fall over once all flowers on the spike are in bloom. If you think this is the case, you might try adding a little ground limestone to the soil.

Our glads are flowering but

Our glads are flowering but there is brown on the flowers edge
Its been very hot in the 90s and humid is it from the heat?

Although there are several

Although there are several reasons for browning flowers (including pests and diseases), if the edges are brittle, not mushy, then our best guess is that it is likely heat damage--especially if the leaves are showing similar symptoms. (Symptoms of heat stress can appear in several ways, depending on the plant, growth stage, and circumstance.) In high heat, water more than the average 1 inch per week. Mulch will help keep the soil moist. You might provide a temporary screen to filter out some direct sun during excessive heat. Some varieties of glads are more heat tolerant than others.

VERY CONCERNED!!!!!! with our

VERY CONCERNED!!!!!! with our gladiola crop this year. We have 150 bulbs planted and it has been very rainy here in Indiana. I was worried about the amount of time it was taking them to bloom, well that is the least of my worries now. I have 5 gladiola blooms that look horrible. After investigation, I noticed microscopic black insects and yellow larvae on the blooms and stalks. HELP!!!! I don't want to lose my whole crop!!!!!!!

Although without a photo we

Although without a photo we can't be positive, it sounds like you might have an infestation of gladiolus thrips, which is a common pest of this flower, and can cause serious damage if not controlled. These are tiny black insects with gray wings; the nymphs are yellowish. They suck sap from leaves, causing silvery speckling, and can also damage the flowers. They can overwinter in the corms. For a photo of the larvae, see:

http://www.corbisimages.com/im...

Of the adults, see:
http://www.lindagilkeson.ca/Bo...

For control, in light infestations, you can hang blue or yellow sticky traps--these lure the adults. You can also knock off the insects by spraying the plants with water from a hose (morning is best)--be sure to set it on fine spray, and do the leaf undersides; repeat a few times each day. Several beneficial insects help to control thrips; you can order these, such as green lacewings, from mailorder sources.

When storing the corms in winter, keep them at about 40 degrees F, which will kill any thrips (do not freeze the corms).

For heavy infestations, you might have to resort to chemicals. Ask your local garden nursery about suggested controls, such as insecticidal soap (in general, this can be applied about every 3 days for 2 weeks, but follow manufacturer's directions). Pyrethrin (pyrethrum) is used for more serious infestations.

Good luck!

I've been growing glads for

I've been growing glads for years and have had nothing less than the usual pests(white flies, tiny catepillars), but this year some kind a pest bit the flower at the tiny stem portion of the flower, and the flowers were left behind in the dirt. This happened with one flower at first, and then the next day about 5 more flowers were gone, eventually all flowers were gone, including buds! The leaves were bent and I saw tiny scratch marks(like a cat's claws) on them. I sprayed the plant and what was left of the buds, but they all vanished. This particular glad had twins and the pest was able to chew the stems, so the twins vanished, too.
My garden is fenced with bamboo and each plant has mini-wire mesh circular fortress around the bottom to prevent chewing of leaves at the base(a method learned from past damage). Never saw any catepillars or larvae in the dirt. We have squirrels, gophers and mice; no deer. I found ants the first day, sprayed them and never saw them again. Squirrels are too heavy to climb the stem without noticeable damage, so I omitted them from being the possible pests; the main stem is very tall(5 feet+), and the highest stolen bud was on the very thin green tip of the stem. I thought mice might be too heavy, as well...but they are my best guess! I read somewhere to place foil discs around the stems, so I've done that for my last 2 glads that are flowering. The green leaf structures holding the buds and flowers were somewhat frayed. Have you heard of mice climbing glads and eating them all the way to the top? Are there any other pests that might do this type of damage?

Hmm. We're stumped! Rabbits

Hmm. We're stumped! Rabbits can sometimes clip flowers or buds off and just leave them, but at 5 feet, that's unlikely without bending the plant; they normally feed up to about 2 feet high. Do you think it might be a bird? We haven't come across any gladiolus pest that would do this at that height (without major damage). Voles aren't good climbers, but can sometimes climb trees a tiny bit if there are low-hanging branches. Mice are good climbers, but their damage in the garden is usually just a few inches aboveground or belowground (although, there are some mice, such as the harvest mouse in England, that can use their tail to help climb tall stems of plants such as cereal grains or reeds). Squirrels can do the damage you describe--do you think a young squirrel, or, if they are in your area, a smaller type of squirrel such as a red squirrel, would be able to climb the gladiolus without bending it too much? Are there chipmunks in your area? Perhaps you can call your county's Cooperative Extension (if you are in the United States); they would know what pests are likely in your area, and perhaps can suggest some possibilities.

I live in zone 5 (I think, east-central Iowa). This year is the 4th blooming season for my glads. The first year, a friend told me when I planted them that before the first frost to cut the stalks and dig them up for winter storage. I forgot, then it snowed and I just left them in the ground, well covered with the seasons mulch. The next summer, to my surprise, the glads poked out of the ground and grew big and strong and bloomed beatifully (though I didnt realize until now to keep them blooming to oull out the dead petals)!! Since then, I do nothing with the glads in the fall, just let them go naturally. In the spring I gently remove dead stalks, and watch again as my glads grow strong and beautifully!! Is it possible that because I have the glads planted on the south side of my house they do so well? Also, when I originally planted them, I didnt realize their height and planted in haphazard way. When is the best time to move them into a better formation, if you will, such as closer to the house as a backdrop for my other flower (day lilies and tiger lilies)? Thanks for your response!!

It is possible that the south

It is possible that the south side of the house has created a microclimate that is warm enough for them to survive the winter. Also, you might have a variety that is a little more cold tolerant than others. You might add some winter protection, such as a thick layer of straw in fall, just in case, if you prefer not to dig them up for winter storage. As to when to transplant, the best time is in early spring.

My daughter-in-law planted

My daughter-in-law planted Glads in NE PA (zone 4-5) a few years ago and has never dug them They are blooming beautifully. They burn wood in the basement and the glads are planted on the other side of the wall. It is also a W exposure. Crazy I know but it is working.

My Gladiolus bloomed good and

My Gladiolus bloomed good and everything. But when they bloomed, the flower bent over all the way. I tried placing it up right, but it came fully out! It wasnt yellow, it just came right out for no reason. Then I noticed another one was bending. So I tried placing it up right, I heard a tiny snap, and I put dirt on it. The next day it started yellowing! All my other Gladiolus I placed upright with dirt are yellowing and im afraid it will end up like the first one. Please help!

I've been having the problem!

I've been having the problem! I read that tall varieties need staking or a grid with stakes and string. I'm hoping mine will come back next year and I can catch them before they start to bend.

Stake glads first thing to

Stake glads first thing to avoid the likelihood of damaging their roots with the stakes. Otherwise, they will easily blow over and snap. Once they die, they will yellow. If plants are yellow or stunted before their natural end, there is a virus infection and there is no cure; you need to pull them out.

Help! My gladious are doing

Help! My gladious are doing well, up to last week. They were growing up beautifully, as I opened up a new area in my garden for them this early spring. Got them planted in good mircle grow soil, and all green and well. 2 weeks ago, I notice some yellowing of one of stalks' leaves, and a few days go by, the whole stalk went yellow, dried up and died. I pull it out. Thought it was just lacking water. Out of the 20 planted in the same location, this is just one that died. I didn't think much of it. Since then, I've watered all the rest of the glads at least once per day, and everything looks good. Then this morning, I notice some other glads are yellowing too. They're getting plenty of sun and water. Yellowing?! I don't know why! Virus? How do I know? What should I treat the soil with so that the rest of the corms planted don't get infected,too? I have tomatoes and other veggies planted nearby and don't want to use dangerous pesticides on the soil.

Any help appreciated. Thanks in advance.

Yellowing leaves could

Yellowing leaves could indicate several things, from overwatering to pests or diseases. Glads like it moist, but not waterlogged; provide about 1 inch of water per week and make sure the soil is well-drained.

Dry rot is a fungal disease that causes corky, dry, brown or black spots on corms; leaves may show black fungi spots at the bases; red-brown lesions may appear on leaves. The plants may turn yellow and die early. With this disease, destroy infected plants and replant next year in a different area that is well-drained; harvest corms in fall in dry weather. With several diseases, it is best not to plant in the same area the next time, because the new plants might contract the disease if it lives in the soil.

Check for signs of insects, under leaves or in the areas where the leaves attached to the main stem. Mites can cause yellowing leaves as they feed on plant juices.

To better diagnose the problem, you might want to bring in a sample to a local nursery or your county's Cooperative Extension. For the Cooperative Extension information for your area, see:

Hi Can I use Peat Moss or a

Hi Can I use Peat Moss or a Lawn Fertilizer when planting my Gladiolus Bubs? Thank you

Add organic materials such as

Add organic materials such as compost and peatmoss when planting glads. Aged cow manure is also beneficial. A 5-10-5 fertilizer can also me used.

I usally have good luck with

I usally have good luck with my glads.I put a small pile of bone meal under each corm,when planting,but wonder if there is some other fertilizer I can use to make corms grow bigger for the next year?

Add compost or aged cow

Add compost or aged cow manure to the soil.

My glads came up and growth

My glads came up and growth was about 3" above ground. The person trimming, weed whipped them in error to about 1". What can I, should I do, if anything. BIG MISTAKE!

This hasn't happened to us

This hasn't happened to us but it should be OK. As long as the top of the corm and growing point is intact, we hope your glads will keep growing!

I will be receiving about 50

I will be receiving about 50 bulbs in a few days. I live in zone 8. Is it too late to plant them?

In your area, gladiolus bulbs

In your area, gladiolus bulbs are planted mid-February until the last of April--so it's just past the traditional planting season. However, you could try the glads and see how it goes. Make sure you feed them for blooms--and stake for Texas winds!

In was given some gladiolus

In was given some gladiolus bulbs and they told me they did good in shade. I planted them along my deck under a late tree, they're coming up now pretty quickly but they won't get any direct sun, should I dig up and move or will the filtered sunlight be ok for them?

They will grow in part shade

They will grow in part shade but may grow tall and require staking. Dig the bulbs in the fall and plant them in a sunny location for better blooms.

I planted about 300 Gladiolus

I planted about 300 Gladiolus corms in the last year. Last year they did great in blooming, this year, they start to bloom, then they dry-up, what gives. I have had only 4 plants bloom, the rest have dried up. I've kept the soil moist.

I'm having the same problem!

I'm having the same problem! Would love advice - this is my first season with glads in bloom.

Can I plant glads among a

Can I plant glads among a rose bed? Are they compatible?

I planted several with pink

I planted several with pink knockout roses and here in Texas they are starting to bloom! Both the Glads and the roses are healthy and blooming.

I planted glad bulb last

I planted glad bulb last year. Due to my health, I did not take up the bulbs. This spring I have all the bulbs growing again, and they have multiple shoots (up to seven per bulb) coming up. I don't know what to do with all the shoots. Leave them, thin them or...

My neighbor has what appears

My neighbor has what appears to be glads coming up in her flower bed, she hasn't ever planted any but I have. Is there anyway they could have migrated to her bed? We're baffled.
Thanks

Hmmm..Glads grow from planted

Hmmm..Glads grow from planted corms (bulb-like structures) that are intentionally planted. Most glads do not come back north of zone 8 because they are not winter-hardy.
Update: Clearly, we are hearing other readers mention that their glads are coming back in zones 7, 6 and even 5.
The reason? Perhaps this change is due to shorter, warmer winters. The ground just isn't freezing as deeply. Other factors might be: heavy mulching in wintertime, deeper planting, and good snow cover. The only way to find out? Leave some glads in the ground and see what happens in your area!
