Phlox are perennials and a favorite choice among wildflowers. These plants sport many star-shaped, colorful flowers when in bloom.

Because there are so many varieties, you can find a type of phlox for almost any garden. Phlox make great ground cover, and you can compliment them with other varieties of ground cover. They are easy to care for and low maintenance. Add some phlox to any bouquet for some nice fragrance, too.


  • Use a garden fork or tiller to prepare your garden bed. Loosen the soil to about 12 to 15 inches deep, then mix in a 2- to 4-inch layer of compost.
  • It is easier to grow phlox from cuttings/transplants than seeds.
  • Plant phlox in the spring and space the plants 1 to 2 feet apart. If you are moving a plant from a pot, dig a hole about twice the size of the pot’s diameter and place the plant so that the top of the root ball is even with the soil’s surface. Fill in around the root ball and remember to water it thoroughly.

There are three different categories for growth requirements:

  1. Woodland species (like Blue phlox and Creeping phlox) like evenly moist, humus-rich soil, and full to partial sun.
  2. Low, mounding phlox (like Sand phlox and Chattahoochee) like average, well-drained, sandy or loamy soil, and full sun.
  3. Border phlox (like Carolina phlox, Meadow phlox, and Garden phlox) like moist, well-drained, and average to rich soil, and full to partial sun.


  • If you receive less than 1 inch of rain a week, remember to regularly water your plants throughout the summer.
  • Each spring, put a thin layer of compost and a 2-inch layer of mulch around the plants to help keep the soil moist and control weeds.
  • Remember to remove the dead/faded flowers so that your plants can rebloom.
  • If you have tall phlox, cut the stems back to about 1 to 2 inches above the soil after the first killing frost. (See local frost dates.) Divide tall garden phlox every 2 to 3 years to ensure healthy and disease-free plants.

Fall planting?

We are moving into a new house in August (Massachusetts) and would like to get a start on landscaping. I see a lot of advice to plant phlox in Spring, but also that you can divide in Fall. Would it be ok to start planting in early fall so that plants can establish before next spring?

Fall Planting

Hi Mary,

Yes, you can transplant phlox plants from a greenhouse from now until early fall. They will establish before the fall frost and continue growing in the spring.

Candy Store Grape Lollipop Phlox

I just bought 3 lollipop Phlox last week Saturday - at a greenhouse ( SE MN) they were even planted the same day. We are currently living on a farm site that we have had to regain control of ...
I water good when planted. Then the next week it rain at least every other day if not daily.
I looked at the three plants planted in a row on the south side of a small shed.. and ONE brown only at the bottom of all the stems right next to the ground... the top leaves still green.. it wasn't completely detached but close. When I looked at the ground, I did see a few ants around it... but i didn't see the ant hill or anything.
Why would one plant die that fast?
what can I do to help the other two?

Phlox bug

Hmm. We can’t be absolutely certain what the problem might be. Some say that overwatering (even if it’s rain) could be harmful to phox. Then we learned about Lopidea davisi—a bug that feeds on phlox and overwinters in dead phlox stems. You might want to contact the nursery and see if they will exchange the plants for you. If this is the problem, you need to cut back and dispose of infested stems and leaves. Apply insecticidal soap to the upper and lower sides of leaves and follow with a light horticultural oil. There is a picture of the bug and a few of infected plants here:

We hope this helps.

Season pictures

Can you pls post pictures of phlox in the seasons? Thank you from Kansas!!!

Best way to plant phlox seeds

I have 1200 seeds should just broadcast them or put them in a seed starting kit?

broadcast or kit?

First, make that kitS, Paul. You’ll need more than one. As to how to move forward, it seems to us that it depends on how much time you have. Kits require preparation and monitoring, then transplanting. Broadcasting … not nearly so much.

Do creeping phlox spread underground?

I have planted my phlox and am not sure how close to the plants I should place the ground cover and mulch. Do the plants spread from the root system or is their growth mainly from the main planting? I don't want to stifle new growth from the roots if that's how they spread.

Growth of Phlox

Hi Vicki,

Good question! Phlox grows from the main planting and can be stimulated to grow new shoots with mild trimming. Mulch up to the roots, but keep in mind that the ground will be covered over time and excessive mulching is not necessary. 

We hope this helps!

Growing Phlox in Hawaii

I moved to the Big Island, Hawaii a few years ago. I have a lot of lava rock exposed in my yard & thought a Phlox of some sort would be a beautiful ground cover & would enhance the beauty of the tropical plants. Unfortunately, I have not been able to find any phlox plants in local area. Our yard gets sun practically all day & where we live we get plenty of rain. Would phlox do well in a tropical climate? If so, which specific type of phlox would work the best here? Would seeds work ok since Hawaii is very strict about plants coming in from the mainland plus it takes so long to get products delivered here. Thank you.

phlox for hawaii

According to the University of Hawaii cooperative extension, Phlox mhnlata which is commonly called Moss Pink is a good choice for warm-weather climates. this is an “evergreen mat-forming perennial that grows to 6 inches high with l-inch-long linear leaves. The .75-inch flowers range in color from red-purple to violet-purple, pink, or white. Easy culture in any garden soil but best with abundant moisture and fertilizer in neutral and alkaline soils, cooler areas with full sun. Rapid cover. Many listed cultivars available.”  I’d ask local nurseries about this phlox or call your local cooperative extension for more on-the-ground advice.


I did not know I was supposed to cut these plants back before winter. Its first of March now and plants look brown and possibly dead. Is it too late/early to cut them back now?

Cutting Back Phlox

At this point/stage, Jimmie, the most important part of the plant/s is underground. You will not hurt them by cutting them back now.

Pink Creeping Phlox for a Day

My son and daughter-in-law are having their wedding reception outdoors in NJ in August. One of her colors is pink, and I would love to have some pink creeping phlox around (in addition to many other pink annuals and perennials). I know you're supposed to plant them in Mar-Apr and they bloom in early summer. Could I put them in my sunny indoor greenhouse so they will stay blooming through early August and I can plant them that week? I want to use them somehow.

Pink Phlox for August

Unfortunately, bringing it into the greenhouse won’t extend the bloom time–its DNA dictates when it blooms, sets seed, and dies back, and there is nothing to be done to change that. But you could try growing a variety that blooms later in the summer, such as Phlox paniculata ‘Pink Flame’, a dwarf cultivar that grows to be 12 to 16 inches tall.

Too late to plant in Vermont?

I had some replacements sent from the nursery, and they just arrived yesterday, even though I had requested them back in early August. I live in Vermont, we are having 70 degrees currently and low 50's at night, no hard frost yet. Is it too late to plant my creeping phlox roots? If so, how can I keep them alive until spring? Thank you! Jess

Planting Phlox

A hard frost is probably not too far off. Go ahead and get them in the ground (that is a better option that trying to keep them indoors), water well, and insulate them with a heavy layer of mulch around the crown. Or you could plant them in a container, water, mulch, and tuck them up against the house or somewhere with a bit of protection; then transplant them into the garden in the spring.


Some of my phlox stems have sprouted babies along its stem--reminds me of the way an airplane plant does. Is this an opportunity to root new starts from each baby? If so, how do I do this? My plants have never done this before.

Phllox babies

Nature’s surprises present wonderful opportunities. Sure, clip off a couple/few of the babies and set them in water to see if they sprout. Or use a bit of root powder (available at almost any nursery/garden store) and set them in dirt (per the directions on the package).

Let us know how this goes!


Hi. Home depot has some really great buys on phlox and I was wondering if it's too late to plant them in Minnesota. August 26, 2016


Should I transfer my phlox which is currently in a pot, into the ground.

Transplanting Phlox

You can transfer potted phlox into the ground any time during the growing season, right up to early autumn. Set the crown of each plant about an inch and a half below the soil surface.

Do deer eat phlox

I have a lot of deer and they already came in (end of July) and ate most of my baby
4 o'clocks. a few survived. If they like the tall phlox that I just bought then can I plant them in shaded area close to my house?

Phlox in Shade

Hi Dejra,

Phlox typically likes full sun. It will tolerate light shade, but it will be less vigorous and won’t bloom as well. There are three species of phlox that are said to be deer-resistant: woodland phlox, garden phlox, and creeping phlox so it doesn’t sound like phlox will lure them away from your 4 o’clocks. Try instead to protect them with netting.

deer and phlox

thank you, i have netting on the 4 o'clocks, now. i don't want the phlox to lure the deer from the 4 o'clocks. just trying to figure where to put them. don't want them to be eaten. so they need sun. I will have to work on this. thank you.


the plant name of mine is phlox paniculata 'Laura' if that helps

Planting Flame Purple Garden Phlox

I live in North Alabama. Can I plant a FlamePurple Garden Phlox or do I need to wait until Spring? I bought it Aug 6th.


Can I take rooted phlox from Middle Indiana to plant in Daytona Beach, Fl, ?? I will do this the first week in Sept. Thank You. Any additional information, will help.

Phlox in Florida

Hi Lennie,

Yes, that is doable. Phlox species grow in Florida. Bear in mind, they prefer moist soil and part shade–their native habitat is deciduous woods and bluffs.


I planted a bare root phlox 2 years ago, I don't remember the variety, but the flowers should be orange. It gets full sun, I water regularly, but last year, and this year, it doesn't flower. the foliage grows great, but no flowers. This is the second year it's grown with no flowers. Does it take a few years to establish before flowering? I'm debating if I want to let it grow another year or so, or take it out and plant something else. Thanks!

Phlox that does not flower

Well, the variety might be the key here. “Bare root” is not a type of plant, it’s simply a descrip of the condition in which you received it, usually shipped, but several types are noted above (see “growth requirements”) and each requires a slightly different moisture level. Based on that, it could be that your moisture/drainage conditions are not suitable. But consider this, too: are your plants getting at least 6 hours of sun? Phlox thrive in full sun; an insufficient amount of sun, even partial shade, will hinder blooms. If this is the case, you should move them. Also, over-fertiliziing, esp giving these plants too much nitrogen, can cause them to grow great stems and leaves but no flowers. A soil test will give you a clue about your soil quality. Does any of that sound like your situation? Phlox do not ask for much. Here’s hoping something here brings these beauties into bloom.

Phlox tall

My stems are either breaking off or something is eating them. When I go to weed/water my phlox this year I have one plant that I find if I barely touch them or even watering a bit of water an them and they fall over and break off.......why is this happening. I have leem oiled it. I purchased a bit stronger bug killer for flowers and put slug killer around all my plants, mostly cause they are just gross! Help me my phlox are my babies.
Thank you for your time!

Reply to Sue

My phlox and blazing star were eaten last year by rabbits or deer. This year I bought the deer and rabbit repellent, so it is a wait and see until they bloom. So far, they have left them alone. This repellent is called Liquid Fence. It has egg and garlic in it and can be purchased at Lowe's or Wal-Mart. As for them falling over, did you check their roots? Could be a gopher problem underground. Good luck Sue!

Did you ever figure out what

Did you ever figure out what was causing the breakage. I have the same problem with mine. There are not animals doing this. This is the plants fourth year. They are gorgeous with beautiful blooms, but they are brittle. I live in northern IL. Thanks!

phlox seeds

i live in central Indiana. Is it too late to plant phlox seeds? I've never had phlox before and I bought the seeds so I could get a specific color.

It’s not too late to plant

It’s not too late to plant the seeds. You may not have as many blooms this year but the plants will have time to grow and get established for next year.

creeping phlox

I planted creeping phlox about a week and a half ago in side bed that gets lots of sun. I live in Louisiana. The plants dry out if I don't water everyday. Do they need to be moved to a bed that doesn't get quite so much sun? A lady who works at a nursery told me creeping phlox does not do well in Louisiana. I have been watering everyday but they look so dry. Please help. Judy Jergins

Creepig phlox in Louisiana

Well, nursery people in your own community usually know best about local conditions…certainly better than we here in New Hampshire might.

The Missouri Botanical site (not either of our neighborhoods, but a pretty reliable source: ) suggests on its link in parent that creeping phlox does best in zones 3 to 9 (which appears to include Louisiana; see here: and likes full sun but “generally appreciate[s] some dappled sun in the hot summers of the deep South.”

And that’s without getting into your soil quality etc., see above this page.

The only other thing we would advise is to return to the nursery and see if they can recommend anothe rplant that will accomplish what you want…just in case the creeping phlox becomes sleeping phlox.

All the best—

Talk Phlox

I just ordered tall phlox. They came "bare root. Can I plant them in a container? I'm in Michigan.can I leave them out for winter or bring them indoors?

Hi Theresa,

Hi Theresa,

Phlox is perennial and will survive winters in Michigan. You can plant the phlox in a container and then transplant it out into the garden. Please see our planting advice at top of this page.

Hi, I planted several types

Hi, I planted several types of phlox in my garden probably about 15 years ago. Every year, they have grown tall and beautiful and have been a staple of my flower beds. Last year, they were not as spectacular and this year , they are even less so. Is it possible that they are too old and need to be replaced? I have separated them many times and they are in various places in my yard. Some are doing ok, but still not as spectacular as before.

Is your phlox getting enough

Is your phlox getting enough sunlight? It needs 4 to 6 hours of direct sunlight at minimum. Do you fertilize?  Applying Miracle-Gro one time per month should be ample. If your phlox does not bloom next year, you may want to rip it out and begin anew.

i leave near San Antonio, Texas I am interested in planting some type of pink & white Plox in a wine barrel. Any recommendations and tips on care ?

I have had phlox for years,

I have had phlox for years, always bloomed nicely, some years had a little mildew, no big deal. Last year, however, and it looks like it's going to happen this year too, I had no blooms! "David" and "Sir John Falstaff" and two other varieties just decided to stay green! The amount of sunshine, fertilizer, water, etc., did not change. I don't know what to do--this perennial bed is in front of my house and the phlox are like the backbone of the display.

Hi Connie, If you have not

Hi Connie,
If you have not divided and replanted the phox recently it may be overcrowded. It's recommended that you divide the plants every 2 to 3 years.

Just planted 2 young phylox

Just planted 2 young phylox paniculata. There are only 2 stems (each plant) about 12" tall. Can I cut them back in order to get more shoots?

You can deadhead the phlox

You can deadhead the phlox and you may get some new smaller stems off the main stem and sometimes it will rebloom. In the fall you can dig up the plants and see if you can divide them to create more plants for next year.

Can someone please tell me

Can someone please tell me where the seeds are found on the phlox plant. I've searched the net and can't get an answer. Thank you so much.

The seeds will develop at the

The seeds will develop at the same location as the flowers. Once a phlox flower has been pollinated/fertilized, the petals will fade and dry and that part of the plant then will form a seed capsule (aka seedhead, seedpod), which is the "fruit." Inside this capsule are the seeds. Different phlox species may have different forms of seedheads, but see the photos below to get an idea. Note that phlox have seed capsules that, when the seeds are mature, will split open (sometimes "explosively") to release the seeds, so if you see an open capsule, the seeds may already have been distributed. Hope this helps!

My sister wanted me to plant

My sister wanted me to plant for her some creeping phlox around her mailbox. I was wondering if anybody knows how they hold up against the sand & salt from over the winter? Being right next to the road they'll get a full dose.

Not sure how old this post is

Not sure how old this post is but my phlox got a heavy amount of snow and salt on it and came back just fine. Doesn't lend an answer to your sand question but they'll be fine. They are tough flowers.

Creeping phlox is a hardy

Creeping phlox is a hardy perennial with some salt tolerance. In the early spring use the garden hose to spray the area with water and wash off as much of the salt and sand left after the snow melts.

I planted creeping phlox last

I planted creeping phlox last year expecting pretty blooms thus sorung. Only 1/7 of the phlox bloomed patchy amount of flowers. The area where I planted gets full sun. The phlox appears green and thriving. Any thoughts as to what happened and what I can do to ensure beautiful blooms next year?

I planted 12 phlox plants in

I planted 12 phlox plants in my garden and they seem to be withering away. I am watering them daily. Does anyone have insight as to what could be the problem? What should I do?

Hi! I planted 3 phlox

I planted 3 phlox paniculata last year, they bloomed they were beautiful. I live in Mintreal so we have hot summer and pretty cold winter. I read some where, that for winter you cut them 2 inches above ground. So I did it. Now, I don't see anything new growing back, they look like dead. What should I do? Are they coming back? Did I kill them?

Hi Mercedes, Most phlox

Hi Mercedes,
Most phlox paniculata varieties are cold hardy in US zones 3 to 8, but there are a few varieties that are tender. It's good practice to cut the stems back before winter like you did. Don't give up yet. The plants may still be OK and surprise you with new growth.

I have woodland phlox "blue

I have woodland phlox "blue moon" just beautiful when they bloom. After, it's a nightmare long brown stalks, leaves are ruff looking and it's mingled w/ weeds.Thought it would be a nice ground cover after it bloomed. I've cut it down to the leaves still in bad shape. Any suggestions would be welcomed.

I live in India where present

I live in India where present temp is around 17°C at night n 24°C during the day. I hve planted few seedlings of phlox which are very small and yet to grow to full size. However a few buds have appeared already which will probably hamper its growth. What should I do? Please advise.

I bought 4 of the David's

I bought 4 of the David's Lavender Phlox and when I received them all the leaves were dead and the stems are dead but the roots are black, tan, and white!!! Are my Phlox dead??? Please help as I don't know what to do. I live in Zone 7 and the company I bought them from said I should plant them now as it is late in October and to put mulch over the top. Do I plant them with the dead stems or take the dead stems off as it seems to me that some of the roots are still fine.

Sounds as if you ordered

Sounds as if you ordered bare-root plants--and yes, they will look dried out and perk up in the growing season. Phlox is usually planted in the spring. It can be planted in fall in early autumn. Fall-planted phlox are more subject to frost heaving, though it's not unusual to receive mail-order plants too late in fall to be planted safely. If you plant them, be sure to add 4 to 6 inches of mulch (hay, pine needles, chipped leaves) as soon as the soil freezes to protect your plants and give them the best chance.

I also have David's Lavender

I also have David's Lavender flock and they get very tall and stringy before they bloom. I am wondering if I can cut them back in late Spring and perhaps they will be bushier and bloom as well?

With phlox, you may pinch or

With phlox, you may pinch or cut back half way -- no later than early June. Note that legginess before bloom often comes from overfertilization, especially use of nitrogen, so avoid this.

I planted a border of

I planted a border of creeping phlox last spring. They bloomed and everything was beautiful. Since then some of the plants have some stems that turn brown and turn to "stickers." There are these brown splotches (about 5% of the total) throughout the border. Is this normal? I keep cutting out the dead pieces, but it keeps happening. Help.5

Hi, Aubrey, This all sounds

Hi, Aubrey, This all sounds normal... It's fall: Phlox is a perennial, it will die back in autumn (as daylight lessens and cooler temps set in). Cut the plants back to about 3 inches (too much more might damage the crown). Remove debris from the bed to discourage diseases. When it's clear that the warm days are behind us, lay on a protective pillow of mulch. (Doing this too soon, while the soil is still relatively warm, might trigger regrowth.) Since this is the plants' first year, leave them intact, but in future consider that autumn is a good time to divide plants.
Hope this helps!

Maybe I missed it but do not see anything on transplanting Phlox. What time of year and how to go about it. Mine are white grow about 5 feet tall and been in place for about 3 years.

The leaves on my Phlox have

The leaves on my Phlox have dropped what can i do,we have had alot of rain would that have coursed the problem.

Do the leaves of your phlox

Do the leaves of your phlox appear to have a whitish dust on them? Phlox is quite hardy but also prone to powdery mildew if it's been humid or wet. It's fairly normal and doesn't usually hurt the plant. You can throw away the affected foliage and pinch off any other affected leaves; spray the rest of the plant with fungicidal soap.
If your phlox doesn't have powdery mildew, sometimes leave drop can happen with older phlox as the summer progresses. This is a signal that you may need to divide your phlox and and replant in compost-rich soil.

Hello there, I'm creating my

Hello there,

I'm creating my own backyard garden this year. I have chosen particular plants for my garden. One of those particular plants is a David Garden Phlox. Before I got it planted into my garden disaster happened. My white phlox broke off at the bottom of the stem. Is is possible to put it into a vase with water to re-route? I was hoping if I could get it re-routed then I could replant in the garden? I hate to think I killed my poor white phlox. Please advise what I can do to save it?

You can still plant your

You can still plant your phlox. It will likely grow new stems from the roots.
You can also try to root the broken stem. Shorten the stem to about 3 to 6 inches long with 2 to 6 leaf nodes. Cut the stem with a sharp knife at an angle just below a leaf node. Remove flowers, buds and lower leaves. Plant the cutting in a pot with equal parts moist coarse sand and vermiculite or perlite. Make sure the lowest leaf node just above the surface.

I had multiple perennials

I had multiple perennials professionally planted in a rock bed in early fall. I have the taller phlox. The came up beautifully the spring, but after awhile they almost look as if they had been nipped by frost, one stem at a time, then within a week or 2 the whole plant was affected and died. This has happened to 4 plants now. Healthy to dead in about 2 weeks. What's going on?

It's hard to tell what caused

It's hard to tell what caused the plants to die. There are three common diseases of phlox. Oedema causes rusty blisters on leaves and petals. Parasitic nematodes (roundworms) turn foliage and stems brown and mottled. Powdery mildew creates a dusty white covering on leaves, stems and flowers.

I have the tall phlox and it always collapses and looks sloppy when it starts to flower. Id prefer not to put a wire cage around it. Is it possible to prune it before it starts to form buds?

You can cut the phlox back

You can cut the phlox back for bushier growth. Early in the season May/early June cut about half off. If you want to experiment cut some less and some more to see how high they will grow.

I am going to be planting

I am going to be planting Phlox for the first time this year. The spot were I am putting it is surrounding by sidewalk. When winter comes our maintenance men will be shoveling and salting the sidewalks. Will the salt effect the plants? Thanks.

Good for you! Phlox are so

Good for you! Phlox are so pretty! A lot of this has to do with what type of phlox, where you are, and how much salt we are actually talking about, but in general most phloxes are at least moderately salt tolerant. We have about 15 feet of creeping phlox along our New Hampshire uphill (well, from the bottom) driveway, the bottom end of which is about 8 feet from the road. Over the course of the winter, we shovel and/or snow blow at least a moderate amount of road salt on the lower part of the phlox bed, and it never seems to be any the worse for wear. Give your plants some help. Make sure the bed is well drained to make it easier for any salt to leach through and not hang around. Ask the maintenance men to shovel in the other direction if there’s salt around—maybe bribe them with a muffin a month or whatever? If you foresee a period of above-freezing temps with at least some sun, you can wash salt off your phlox, too—that can be of help. Finally, consider doing a little test: Cover a small part for the winter and see if it makes any difference. Then you’ll know what to do the next year. Good luck!

I have a small, rock lined,

I have a small, rock lined, flower bed in the front yard..I usually plant impatiens in it but have to replant yearly. I was thinking of adding creeping phlox. Today is April 21st and I'm wondering, since I saw them in pots at my local garden center, if I plant them now will we see a lot of flowers this spring? It's been cold here. Also, I would say the flower bed is about 4ftx4ft, the pots were about 6inch pots. Don't want to over crowd and wondering how many I should pick up? thanks

It's best to plant phlox in

It's best to plant phlox in the spring as soon as the soil is workable. As your area gets very cold in the winter, be sure to add 4 to 6 inches of mulch in the fall as the soil freezes. 

My creeping phlox have

My creeping phlox have bloomed beautifully for 2 Springs and I have not trimmed them. After an unusually long winter (with lots of snow), the plants all look brown and dead. The only new shoots I'm seeing are either at the ends of the long dry sections, or deep in the center. Should I cut off all the brown?

Trim back the plant(s) it

Trim back the plant(s) it finishes flowers. Then, fertilize with a general (e.g., Miracle-Gro) fertilizer. A bit of fertilzer every year would not hurt, and some sources suggest shearing the stems one-third to one-half after flowering every year to encourage new foliage—and possibly a second flower display.



Cut out the woody stems in

Cut out the woody stems in the middle that no longer produce flowers. Tender new stems will replace the old ones. It's a good practice to cut off any spent flowers in the summer to encourage new growth and prolonged bloom.

I bought three phlox but

I bought three phlox but could only keep one alive by taking it out of the ground and keeping it in a large pot. It's growing great, but I don't know what to do with it during the winter. Can I bring it in? Should I plant it now? Or should I just leave it in the pot until next spring? I can't find any information on this dilemma. Thanks

It all depends on what type

It all depends on what type of phlox you have. Most phlox varieties are cold hardy and tolerate winter chills. Find out what kind of phlox you have and see if it is cold hardy in your zone. If the plant is doing well you can plant it in the ground in the spring.

I have beautiful phlox which

I have beautiful phlox which I did not deadhead this summer when the blooms were done; Now for the first time in all the years I have had these plants they have bloomed again, as beautifully as the first time. This seems to go against all the advice given here. What gives?

Our guess is that your phlox

Our guess is that your phlox bloomed, went to seed and dropped the seeds in the soil. The new plants grew fast enough to start blooming before the end of the season. You can check to see if the phlox bloomed on the old stems or new stems.

Y'all keep saying phlox is a

Y'all keep saying phlox is a perennial, then how come I keep reading about how it "comes back next year" and " . . "had plant for over 3 years", and "if your phlox does not bloom next year, do so-and-so", etc. Well I've reached the conclusion that if I cover it over with deep mulch maybe it'll stay alive through the winter and COME BACK IN THE SPRING . . . . RIGHT? ? ? ? (I'm in Colorado)

I spent the first part of the

I spent the first part of the summer pulling out phlox from around my house and picking the little green seeds off my cats. Is all phlox like this? It's pretty but the seeds are a pain in the butt.

To avoid this issue, just

To avoid this issue, just deadhead your phlox before they go to seed. This is good practice (not just because of your cat); the little seedlings tend to crowd out the mother plant over time.

there is an annual phlox one can purchase often in multi colored mix seed packs. They grow to about 12-18" tall and if trimmed of flowers going to seed will continue flowering all summer.

Is your phlox getting enough

Is your phlox getting enough sunlight? It needs 4 to 6 hours of DIRECT sunlight at minimum. As you mentioned, you can also fertilize. Applying Miracle-Gro one time per month should be ample. If your phlox does not bloom next year, you may want to rip it out and begin anew.

Hi, when you say remove the

Hi, when you say remove the dead flowers so it will re-bloom, do you mean just pick off the dead flowers or do I cut the small flower stems that the dead flowers are on.

Deadhead the dead bloom a

Deadhead the dead bloom a quarter-inch above the next bud. You can use a pair of snip with sharp scissors or hand pruners. 

I live in MN and planted 3

I live in MN and planted 3 creeping phlox this spring to go over a retaining wall. They aren't blooming at all and they aren't creeping. What should I do?

We live in Plano TX, have

We live in Plano TX, have planted two shades of lavender creeping phlox last year and early this spring but none are flowering! Any ideas on how to encourage them to flower? They get some shade in the morning and afternoon sun, and are usually watered once a day when the weather is dry. Thank you!

Sprinkle 10-10-10 fertilizer

Sprinkle 10-10-10 fertilizer around the plants and mulch with compost or other organic mulch to keep the soil moist and weeds down.

Creeping Phlox

It says phlox likes sun, but it says creeping phlox enjoys shade. Which is true?

Mowing phlox

If I plant them in my yard...after they bloom can I just mow over them with the rest of the yard grass?


I planted my phlox Sunday and it was 70 degrees but today it's snowing... In late April! Is my phlox going to be ok?

yes, they are a spring

yes, they are a spring blooming plant. Mine was all bloomed 70 degrees one week, snow the next, still perfect. Dont worry too much about them, once they start to grow they grow pretty rapidly.
