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. The plant is also great for cut flowers.


  • Plant gladiolus bulbs in the spring once the danger of frost has passed and the soil has warmed. See your local frost dates here.
  • 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.


  • 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.




Storing Gladioli

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

  • Use a space and dig up the 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 in a 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.

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:
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:

Of the adults, see:

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. She asked me when would be the best time to split the bulbs. I gave up on glads years ago and so am no help. Any suggestions?

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.

This is my 1st attempt at

This is my 1st attempt at growing Glads.... they were planted at about 6-8 inches depth.. they have beautiful TALL leaves, but no sign of blooms.... what should I do???

Mine took a full year before

Mine took a full year before they bloomed. I planted thm last year for the first time and had big tall shoots but no blooms. This year they finally did bloom and they were beautiful. I did have to stake them though. I was wondering if they would continue to bloom but they haven't.

Hang in there. Glads bloom in

Hang in there. Glads bloom in mid- to -late summer. We hope it's just a matter of time.

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:

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 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.

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!

We live in Zone 7 and my

We live in Zone 7 and my neighbor has Glads growing in her front yard, she is not a gardener, never tends to them, no weeding or fertilizer and they come back every year.

I live in z5 in michigan and

I live in z5 in michigan and planted glads 5 years ago. I've never dug them up for the winter and they have become prolific bloomers. I tried digging them up to relocate to my sunnier garden so some of the really small corms have come up. There are now almost 20 plants that should start blooming last year. More light has encouraged taller plants and more blooms.

The bulbs may have been moved

The bulbs may have been moved from your garden to hers by squirrels or chipmunks. I have watched the critters relocate bulbs at my house.

I remember an aunt who had

I remember an aunt who had rows of beautiful glads every summer. Every fall she dug them up and every spring she replanted. But I remember her soaking them before she replanted, and I seem to remember my mother saying lye water. I have some stored glad corms, do I need to soak them before re planting?

Soaking corms is a common way

Soaking corms is a common way to control thrips, a challenging pest. As they go into storage, soak for 6 hours in a mixture of 4 teaspoons Lysol ® or other disinfectant and one gallon of water. Allow corms to dry before storing them.

My Glads are in full bloom

My Glads are in full bloom and very beautiful, here in south Texas. Question: Will they continue to produce blooms if I cut the flowers for vases? My plants are currently about 3-1/2 feet tall. I would hate to cut the flowers and have a bare flower bed.

Gladioli usually bloom once a

Gladioli usually bloom once a year. Cut the flower spikes when they have one, two, or possibly three flowers open; the rest will open in order, up the spike. Allow at least four leaves to remain on the plant if you wish to re-use the corms. Then let your plant die back naturally, as it needs to make next year's flower before dying back this year. If you would like continuous flowers, plant more corms subsequently and that way they will keep coming!

How long can the bulbs be stored?

Can they be stored in a refrigerator?
I don't have a well ventilated room of 35-45 temperature, where else can I store them?
Can I store them for more then a year without planting them? How long will they keep?

A refrigerator is too cold

A refrigerator is too cold for the bulbs. If the bulbs are firm and dry you can put them in a paper bag and keep them in your coldest room. Check them regularly for soft spots or rot. If a bulb is soft discard it. They should be OK for a year.

Moved Gladadiolus from pots to ground

Transplanting gladiolus

I started many bulbs in pots. They are doing well and I would like to transplant them, but
we can get light frost through June 10th here. Is it OK to transplant them now or do I need to wait until all danger of frost is past?

You are in USDA hardiness Zone 5b.

How long from planting to blooming?

You can plant them now if the ground is warm. It can take 3 mos. For them to bloom into flowers.

How long do flowers last?

Do the flowers last for days or weeks? As I stated earlier, I'm trying to have them in full bloom for Sept 7th. If I plant now that is 112 days, so I'm afraid they will be done before the wedding. Thanks for your input. It's a challenge to have all of the flowers in full bloom at the right time! :)

I might have a solution to

I might have a solution to your problem. check online to see what the average time to bloom for your variates (usually 90 days avg). Then divide your bulbs into 3 and plant 7-10 days apart starting at 85 days prior lets say. That way you won't have all of them bloom at the same time but you'll be assured that you will have some of them at the peak of their blooms.
Another solution is to plant some of them at different locations (ie:south, west, etc) so that the maturity dates will differ if you plant them at the same time.
Hope this helps! ;-)

Storing bulbs

I know I have to dig my bulbs this fall, but not sure how to store them. My basement is heated, and the garage is VERY cold.

What to plant with glads

What are good choices of other blooming plants or even showy plants to plant with glads to highlight all in the garden? Annuals and/or .

I have asian lilies planted

I have asian lilies planted in front of my glads. They grow half the size and bloom while the glads grow to bloom. I also have a couple of rose bushes including a JFK rose bush. Daylilies are also a good option. They're blooms will be in full swing just before the glads begin to bloom.

There are lots of daisy-type

There are lots of daisy-type flowers that grow into a low bush with lots of blooms all summer. In Georgia I've seen both the 'traditional' yellow and white daisies but also some lovely purple varieties as well. I am going to get some this weekend for the same purpose ... to hide the wilting greenery after the gorgeous Glad blooms are gone.

Gladioli start

Can I plant Gladiolas in Atlanta GA in May?

I bought a bag of 70 gladiolas from BJ's wholesale club because they were really inexpensive and I got the gardening bug this year. Can I plant them the first week in May and have them bloom by the end of summer or should I store them per your earlier posts and wait to plant before the first frost? If I can plant them, should I stagger planting them so I have blooms throughout the summer?

Now is a good time to plant

Now is a good time to plant bulbs for summer bloom. It's a good idea to stagger the planting to prolong the bloom time. 70 glads will make your garden smile!!

Can I transplant while blooming.

I live in East TX. I found some glads in the woods behind my house. They are full bloom right now. When is the best time to dig them up to move? Is it ok now, or should I wait til the blooms fall off.

Transplant advice

I planted glads in a few spots last year they were beautiful! I decided to get rid of two of the flower beds I would like to move the corms, but I'm not sure if I can right now it's the end of April, in massachusetts south of boston we have had a cold winter and spring this year, there has been no growth yet. I have friends who leave theirs in the ground and they come back each year so I left mine. I'm just asking if I can try to move them or is it a bad time of year to do so

You can move them now. Just

You can move them now. Just be careful when you lift them so that you don't damage the corms.

No flowers

I planted the bulbs last year and they all came up with thin leaves, which in time just fell over - no flower stalks came up at all. They all came up again this year, but once again, it's just the leaves, no hint of a flower stalk again. What's wrong?

If your glads are close to a

If your glads are close to a lawn they may have been getting too much nitrogen from lawn fertilizers. Nitrogen promotes leaf growth. Add bone meal to the soil and in a few weeks add a bloom booster fertilizer. Also make sure that the bulbs are not planted too deep in the soil.

what zone am i?

i live in utah what zone is that?

Depends on where in Utah

Utah varies depending on which part you live in. It ranges from 7B-7A-6B

should I cover ?

It's April 18th here in Missouri, & I have a lot of glads coming up, but its suppose to be near freezing tonight, should I cover them ..........

Glads should be lifted in

Glads should be lifted in places that freeze (zone 7 and lower). If yours are in the ground, try to protect them with a greenhouse plastic covering. It will heat up the soil and speed the plant along while protecting from frost. If the corms are planted too soon in cold soil, they will rot.

To dig up or not

Hi, what zone is MA. And do the corms get dug up each winter or not?

Folks, see map page:

Folks, see map page:
MA has more than one zone.
It's recommended to lift the bulbs in the fall in zones 7 and lower.

whats the zone

I live in Modesto, California so what zone do I live in?

Modesto, California is USDA zone 9a.

How to I transplant Glads?

I forced some Glads in a large vase filled with rocks and water following some directions I found on the internet. It is now mid April and they are not calling for anymore really cold weather here in GA. The stems are getting really tall and starting to fall over. However, I do not know how to transplant them. Will this damage their roots? Where should I plant them? I don't want them to die because they seem to be doing so well. I would really like for them to bloom and flourish.

You can plant the glads

You can plant the glads outside if you carefully take them out of the vase without damaging the roots. Plant them in full sun. Dig a deep hole, add some compost and put the bulbs with the roots in the hole. Fill with soil. See above for planting and care information. Put stakes next to the tallest glads.


Last Spring I planted (zone 6) 75 glads as per the instructions on the package exactly. Not one came up. Do they bloom in year 2 normally?

Most glads are tender bulbs

Most glads are tender bulbs that can't freeze--and Zone 6 is iffy. They don't always come back if it's a cold winter. I've made that mistake, but the bulbs are fairly inexpensive. If you plant some new glads now, you should have blooms in 90 days!

I live in RI, if I put hay on

I live in RI, if I put hay on the top of my flower beds in the fall will the bulbs be ok for the winter

Most of RI is too cold to

Most of RI is too cold to cover with hay. In hardiness zones 7 or colder, corms should be dug before the first frost, stored, and replanted in spring.

I Live In RI

I have way to many Glads in my flower beds. They have started to come up and have the green stems on them, can I transplant them now before the flowers open up to other areas in my yard?

Yes, you can transplant them

Yes, you can transplant them now. Dig carefully so that you don't disturb the bulbs and roots. Plant in new spot and keep watering to prevent transplant shock. You may loose a few flowers but most should be just fine.

I live in Middletown,RI

Where I live, I have never had to dig up my bulbs,(gladilous,tulips,cana,daffodils,columbine, etc;). All I do is put the Fall leaves on my flower beds before the 1st frost. Hope this helps you. Happy Gardening!

When to plant in ZONE 7

I live in Oklahoma and am planting a few gladiolus as well as a few other things for the first time this season, and I am not quite sure when exactly I should plant them? I know they say last frost, but that's sometimes hard to determine here.

You can plant the glads now.

You can plant the glads now. See our frost chart at with last spring frost dates shown for Oklahoma.

Corms too old?

I bought corms last November and I would like to plant them this coming April. Thing is is that they were on clearance from last summer - would it be okay to plant them after they've never been in soil for this long? How long can the corms last without being planted? I kept them cool & dry all winter. Thanks!

As long as the corms are dry

As long as the corms are dry and there is no visible rot they are fine.

Planting gladiolus!

So Im planting gladiolus this spring :) been wanting to for awhile. Just wondering if I should lift the bulbs in winter? I live in paso robles, California, zone 8 :)

You can leave the bulbs in

You can leave the bulbs in the ground. It's recommended to lift the bulbs in the fall in zones 7 and lower.

wild gladiolus

I saw one blooming in the woods next to me, went over and pulled up a bunch of bulbs and planted them in my yard. Now a couple years later they pop up everywhere in my yard. Is there any reasoning to this? Also why do some bloom and others don't? Thanks

The corms multiply by

The corms multiply by producing new corms on the top of the mother corm. You can dig them up in the fall and replant them where you want them to grow. The ones that don't bloom are probably the newer smaller corms.

I live in Fresno, CA and have

I live in Fresno, CA and have left my bulbs in the ground for the last three years. I noticed there is a lot of leafy (almost looks like tall grass) growing around the plant. When I dug it up to see what it was it looked liked little mini corms. What do I do with this? and will they grow to be full size gladiola plants?

They are mini corms and will

They are mini corms and will grow into big corms. Leave them where they are or you can transplant them.



cold corms

What's the weather forecast now??
With that in mind, if more cold days are likely, or worse, frost, you should probably just leave the foliage alone until all threat of cold weather has passed.
Glad corms should be lifted before cold weather sets in. Since you did not do that, consider whether or not they are deep enough in the ground to avoid the effects of any surface frost. If so, they may survive. Lifting them now may not make any difference.
We hope this helps.

Indoor Gladiolus Help!

My daughter brought home a bulb from school. I planted it in a pot 11 1/2 inches in diameter. She had no idea what the bulb was. The only place I could put the pot was next to the heater. I usually keep the house at around 64 degrees. Now the gladiolus is about 1 1/2 feet tall! Is the placement of the flower in an adequate area? If so how moist do I keep the soil? How often do I water it? I don't want to disappoint my daughter by having the flower die. Please help. I don't have a green thumb and plants often die on me for some reason.

Your plant will need lots of

Your plant will need lots of sunshine and moist soil. Do not over water it, as this will drown the plant.


I live in Zone 8-9 in Folsom, CA. Can I plant Gladadiolus every 30 days beginning now? Can I store them in my garage until March, 2013 without causing them to rot or become too dry? Any advice? Thanks! Al Figone

Wait to plant in March. Then

Wait to plant in March. Then plant the bulbs every 2 weeks to get a longer flowering period.
Store the bulbs in a box or paper bag with sawdust. They should be fine in your garage if it doesn't get really cold in there.

mold on corms

A successful gardener gave me some of her corms after digging. They have some mold on them, but no soft spots. Maybe she put them in a plastic bag before they has dried much after being dug? Are they worth storing and planting next spring?

Gently brush off the mold and

Gently brush off the mold and wrap the individual corms in newspaper. Store them in mesh bags in a well–ventilated room or put them in a paper bag and store them in a dry cool place. Check the corms a few times during the winter months and remove any that are soft.


I just moved to WA state from CA, and have 3 acres of gardens, trees and lawns. I know nothing about gardening, and I want to keep these gardens alive. I have Glads, Hydrangeas, fruit trees and more. How can I learn to take care of these gardens?

Sounds exciting, though a tad

Sounds exciting, though a tad overwhelming! If you look at our Gardening center, you'll find plant pages on glads, hydrangeas fruit tree, and more. See: That might be a good place to start.

Glads every year

I live in NJ and leave my glads right where they are and they come up every year. I usually don't touch them.Will that continue to work?
Is there something I can cover the ground with ( mulch burlap ) to keep the ground warmer if a very cold winter develops?

Glad for glads

Far be it from us to change a course of success, but this may be the time. Our weather prediction is for colder than normal temps in NJ, and depending on how deep your bulbs are and how much rain/snow falls (and then seeps down and freezes and, say, melts and freezes again), you might wish you lifted them. You could try adding a few extra inches of mulch (the chunky stuff, bagged or loose, used to line garden beds); that would effectively make the bulbs deeper underground. If you have a lot of glads, maybe split the difference and lift some of them and mulch some of them. We hope this helps!


hi i live in christchurch new zealand ive been growing and showing glads for about five years i dig my glads up every year so i can clean them and check them that they dont have any disease or rotten christine

I live in the Willamette

I live in the Willamette Valley, in Oregon. Will I need to dig up the bulbs in the winter?

Glads are not hardy below

Glads are not hardy below USDA Zone 6. In your area they may over-winter with a thick layer of mulch.

still blooming

I planted about 50 glad bulbs at the same time last year. They all bloomed over a period of 6 weeks. Left them in the ground (KY) and this year (after a mild winter, summer drought, and excessive heat) they have been blooming since June...and we are still getting some blooms and it's nearly Oct. I love it, but is this normal?

Yes, it's normal. Gladiolus

Yes, it's normal. Gladiolus bulbs (corms) grow and multiply in the first year. Every 3-4 years you need to lift and divide the corms so that they don't get too crowded. Dividing is best done in the fall after the blooms fade.

i live in North Central

i live in North Central I need to dig up for winter?

According to your UofA

According to your UofA extension office, "Gladiolus can be left in the garden year round in most parts of the state, but hard winters which freeze the soil to the depth of the corm will kill them. Most people that grow gladiolus for cut flowers dig their plants each fall and store the corms in a dry, frost free area over winter."

Newcomer to Glads

I live in Missouri, will I have to dig Glads up during winter, never grew them, they are just now ready to bloom. How do you store and is a garage ok?


Yes, you need to dig the bulbs after your first frost. Place the bulbs in a warm dry area for a week or two. Cut the stalks and put the bulbs in a paper bag. Store in a cool, dry area. Garage is OK if it doesn't get too cold in the winter months.

im in zone 8b is it ok to

im in zone 8b is it ok to leave tha cone in winter time...and i want to change the plase .when can i dig it and plant?

Zone 8b

Yes, you can leave the bulbs in the ground if you add mulch to the top of the soil. In early spring dig the bulbs before they start growing and move them to the new location.

Help please

In March I planted over 8 bulbs they bloomed so beautifully by May. After one set bloomed the flowers died within two days. The rest bloomed and all the flowers died within a week. I pulled the dead flowers off in hopes more would bloom but it didn't. Soon the stalks started to die. Now the stalk are a yellow green with no life in them. What can I do now. I would like those flowers in my garden again. What to do?

Gladiolus only bloom once per

Gladiolus only bloom once per season. They need a dormant period of 2-3 months while they produce new corms. When the flowers die, you can cut off the stalk. Let the foliage turn yellow and die back. If you live in a warm climate (zone 7-9) you can leave them in the ground. If you live in zone 6 or less, then you need to dig the corms up and store them indoors for the winter. If you wish to prolong your blooming season next year, plant the bulbs at 2-week intervals in the spring.

Zone 3

I live in Montana and I have successfully arrived at the flowering period almost at September. I saw that you wrote it needs a dormant period of 2-3 months after flowering. So does that mean I dig them up in November- December? And just cover with mulch until then? Or do I dig them at the last frost? Which might happen in a month and a half maybe. We've already had one frost in the last week of August.

Zone 3

You need to remove the bulbs before the ground freezes. We suggest that you dig them after you have had a couple of frosts. Put the bulbs in a dry protected area to dry for a week or two. Then put them in a paper bag and store in cool, dry area over winter.


Thanks! Do I cut all foliage and just leave the bulb? I'm new to this.

Zone 3

Leave about an inch or two of foliage. Good luck!

No flowers:(

I Live in Massachusetts and planted bulbs in April. I have tall green stalks but no sign of flowers or buds and it is August. Any idea what's happening?

Gladiolus flowers usually do

Gladiolus flowers usually do not have a problem blooming. Here are tips that might suggest the problem: 1) Gladilus corms need to be lifted in the fall. Did you lift them? And did you store correctly? 2) The soil needs to be well-drained so they don't have corm rot; dig one up to inspect. 3) If you buy small corms, they may not bloom; buy big, health corms. I hope that this helps!

Might yet arrive

I planted in March, April and May. Some of the ones planted latest flowered first. Some of the ones planted early are just coming into flower now (August). A good many are still growing and I'm expecting them to flower in September.

The flower buds on some of mine looked just like a tight clump of leaves until two weeks before blooming started, deceiving me into thinking no flowers were coming this year.


I planted in March and gave up seeing any flowers but last week they bloomed over night,i could not believe it they are beautiful

Yes, they are dead, dead,

Yes, they are dead, dead, dead. Try again next year.

dead dead dead

I live in northern New Brunswick, Canada and most of the glads only came into bud in late august,they are now in full bloom the middle of september. Dont give up hope

Late planting?

I purchased 10 bulbs in July and live in zone 6. Can I still plant them this year or will the bulbs survive un-planted until next spring for planting?

Since it takes about 90 days

Since it takes about 90 days from planting to root, bloom, grow, and store enough energy for next year, it isn’t advisable to plant glads now in your area, since the frost will come before then. (About the latest you should plant is early July.) You can, however, try to save the corms for next spring. With proper care, they should come through the winter fine, as long as they are healthy. See the directions under “Harvesting” above for guidelines about overwintering the corms.

Gladiola rot

i planted 7 gladiola corms in a large plant potter made for the porch made sure they were 4" deep and i watered them and had them sitting in the sun, but the problem was instead of seeing anything growing they rotted in the soil what can i do to avoid this from happening again.

It could be that they had a

It could be that they had a disease that caused them to rot. For example, Fusarium corm rot, also called yellows, is a common problem with gladiolas. Before planting corms, check to see if there are mushy spots, discolorations (such as brown areas), etc. If so, throw them out so that they don’t infect other corms.


After the flower dies I'm left with what looks like a seed pack , is this another blossom coming out ?


Those are seeds and can be harvested and started in pots. But if you want to save the existing corm you should remove the spent flower and not allow the seeds to set as this takes energy away from the corm in the ground.


What happens if you just leave the corms in the ground over the winter after you cut the stalk back?


If the soil freezes you will loose the corms. In a warm climate you can leave the corms in the ground.


After I plated some last summer it seems like 100 baby bulbs have sprouted up next to the original bulbs but the are now not growing well, what can I do? Is it to late to have beautiful flowers his season?


The baby bulbs need time (ususally 2 years) to mature before they bloom. In the fall dig up the bulbs and replant them in a larger area so that they have more space to grow. if you live in a cold climate store the bulbs and replant in the spring.


I planted 10 bulbs, 7 in a rather shallow plastic shadow box. The other three are in a pail. I have a patio garden. They are all producing leaves and one in deeper soil is starting a flower stock. Can I re-pot these into other pots without damaging the growth or do I need to wait until next year?


For best results gladiolus corms need to be planted about four times as deep as they are wide. The shadow box may be too shallow for healthy growth. You can carefully repot the glads with only leaves to bigger pots. Don't move the glads with flower stocks.

gladiolus in maryland

I live in Maryland, can you please let me know if I need to take the bulbs out for the winter.

Glad for advice

I moved into a place that have gladiolus. The garden had not been taken care of for years. Only a few blossomed and they did not look that great. Is there a way of reviving them for next year or should I did them up and plant new bulbs?

Glad for Advice

I live in Massachusetts and do not dig them up for the winter. I have grown glads for years and every other year, in the fall, I dig them up and replant the healthy corms. This will keep them at the right planting depth and ensure healthy corms. A little plant food in the whole when planting is also a good idea. Your corms are just fine, by now they are probably at the wrong planting depth which inhibits bloom.

Thank you for the

Thank you for the information. This is the first year I've had glads in my garden and wasn't sure how to prepare them for winter.
