Hardy Mum

Hardy mum winter survival care tips

I had saved my  hardy chrysanthemums in their original plastic pots and put the potted plants into the ground to over-winter.  Now, I want to remove the plants from the plastic pots and transplant directly into the soil. When is the best time to do this?

Hardy mums

Not many of the “hardy” potted mums bought in autumn in zone 4 will survive the winter. Even though they are called hardy mums, their hardiness can vary. Cold winters and poor draining soil are some of the factors that have an affect on their survival.  In addition, when growing mums for the market, growers pay more attention to color, shape and abundance of flowers than to cold hardiness.  The result is a beautiful plant with a root system that cannot support it.

Buying mums
When buying mums make sure they are hardy cultivars that fit your climate. In northern climates early blooming mums are more suitable.  In zone 6-7 mid-season mums are better. Choose plants with buds that are just starting to open and show color.

Watering
By the time your potted mum hits the market, the plants are usually pot bound and full of roots. They will have a tendency to dry out much faster and need to be monitored every day for watering.  If allowed to dry out, the lifespan is reduced.

Planting mums
Planting in the fall, doesn’t always work because there may not be enough time to develop a good root system, so for any chance of success plant in early fall or 6 weeks before the first frost.  Plant your mums in an area with good winter drainage.

Best time to plant hardy mums is in the spring. In your case, try transplanting in the spring, when the soil is workable; if any viable roots wintered over, you should see some green shoots emerge when the weather warms up. Otherwise, buy hardy mum plants in the spring and see how big they get by autumn.

To help hardy mums survive the winter outdoors cut them back down to 6″ after they are done blooming leaving some of the stems to trap winter snow for insulation.  Also, mulch your mums after a hard freeze with several inches of straw, pine needles or evergreens, the added insulation will protect the root system.  Avoid using leaves as they tend to mat down and add little insulation.

Save your mums
Too late to plant outdoors? Keep your mums through the winter and plant them in the spring. Bring your mums inside before a hard freeze. Leave the plant in the pot and don’t trim it.  Store your mum in a cool spot such as a garage or a shed. Water occasionally to keep the soil from drying out completely. Check on them periodically during the dormant winter season. In spring, when new growth emerges at the base of the plant, trim the dead stems and plant in the garden.

    I was wondering what the botanical name is for garden mums.

    Garden mums is known as Chrysanthemum X morifolium, it has been currently renamed to Dendrathema X grandiflorum

    I had beautiful mums planted and the deer nibbled the flowers off and more buds are forming. can I spray the plants with deer repellant without hurting the plant?? Also I planted Missouri Primroses in the fall,, which are perennial, will they sprout in the spring?? thanks for your help.. thanks for your help on getting my Peace lily to bloom for me with the right fertilizer you recommemded’ middle number higher then the first’

    Hi Nancy,
    It’s ok to use deer repellant on the mums. It should not hurt the plants. If you planted Missouri Primrose (Oenothera missouriensis) seeds, they will sprout in the spring and bloom the 2nd spring. If you planted the tuber-like root, it should return next spring and bloom. I’m glad your peace lilies are blooming-congratulate yourself !

    Winterize hardy mum
    We have received potted mums as a gift. We are in Connecticut. They are currently in beautiful, large ceramic planters and these are outside on our front patio. We would like to care for them properly over the winter so that we can plant them in the garden in the spring. We have either dark rooms, or rooms windows that the sun comes through so strongly it burns anything we’ve put anywhere near them. Would it be too cold for them to winter in the garage ? There are windows and the garage is attached, so nothing in there actually freezes.
    What else do we need to do? trim them? water ?
    Thank you.

    The best way to winterize your mum is to keep it dormant. A gargage will work as long as it doesn’t get too much below freezing in the dead of winter. Trim back the plant as it will die back anyway. We want to protect the crown and roots of the mum. Use straw/ mulch on top of the plant for additional protection. Wrap the container with some kind of insulation (bubble wrap, plastic)to keep the roots from cold damage. Check on it periodically during the winter and give it just enough water to keep the roots moist.

    I planted some hardy mums in pots with coleus. After a few weeks, the blooms died and I haven’t had any more, but the plant seems to be healthy. How can I get them to bloom again?

    Generally, once your mum is done blooming that’s it for the season but you may still get a few more flowers by deadheading the old flowers. There may be more flower buds under the spent flowers.

    I recently received a potted mum from a garden center – just the spring flower displays of potted plants. Since it has absolutely no information on the pot to identify the mum, is there any way for me to know if the mum is a hardy variety or an annual? I want to plant it outdoors permanently, but if it is an annual it might turn out to be wasted effort.

    Hi Jenny
    If the mum has bright large flowers on it then most likely it’s a greenhouse plant and not hardy. Hardy garden mums usually have smaller flowers not as showy as the greenhouse variety and would be sold(in Northern states) as small green plants with a few blooms or none at this time of year. These would be planted in spring to get a full season’s growth before they bloom in the fall. You can plant the greenhouse mum in the garden and it might rebloom in e. fall but will not winterover.

    My fiance gave me a mum for Mother’s Day. It actually has three plants in the pot: one yellow; one pink; and one light purple — very pretty. We live in southwest Missouri. Can I plant it outside?

    I’m guessing that it is a greenhouse mum that may not winter over but you can plant it outdoors at this time and it should grow all summer long . If you’re lucky, it may rebloom in the fall.

    I have bought 2 mums from a popwarner football fund raiser..can i plant these mums into a pot then into the ground after flowering and hope they’ll come back or will this lessen the chances and they should be directly into the ground first…thank you

    Hi Vickie,
    If you want any chance of them coming back you should plant them in the ground so that they have enough time to establish a good root system before winter. If you want to enjoy them in a container- here’s what you can do. After the mums are finished blooming, instead of planting them in the ground, keep them in the container and move your mums to a cool place such as an unheated garage. Water occasionally, just enough to keep them from drying out completely. When you see new sprouts of growth in spring, remove any dead, dried stems and plant in the garden.

    Hi,

    I bought some mum plants from Lowe’s. They were v.pretty when I bought them but as the days passed they lost their color and they no more look healthy. I have other mums that I planted last year and I managed to keep them alive thru the winter by keeping them in the apt.Today to my horror, I discovered that the plants I got recently have some insects and worms on them. I don’t know what pesticide I shud use… I am worried that it may spread to the other plants I have…I live in CA

    Hi Reema
    How disappointing that must be. Not knowing what type of insects are eating your mums makes it difficult for me to recommend any type of pesticide, especially if it’s used indoors. I would isolate the mums from other plants just to be on the safe side. If you have an extension office nearby, take the insect to them for ID. Your other option is to return the buggy mums to Lowe’s.

    Hi, Thanks for the response… the insects r really tiny… smaller than mustard seeds.I’ve seen such insects on rose plants back home…. and there r some brown worms in them too…The plants r outdoor but I may have to keep them inside during winter. I have a toddler at home and am 8 months pregnant.. Anyways, I am clueless ..I don’t have the receipts either…Reema

    Hi Reema
    Do the tiny insects move-jump? The brown worms may be beet armyworm larva which feed on the flower as well as leaves and can be treated with Bacillus thuringiensis sold as Dipel, Bactur, Thuricide. BT is a biological control which the caterpillars must eat to be effective. Spray the plant when they a feeding. Once the caterpillar chews on the leaves and eats the parasitic bacteria it will die within 24 hours. Its possible that the black mustard seeds can also be caterpillar excrement.

    Pinching Mums
    I want to buy hardy mums to plant in my front yard next year where there is currently grass. 3 questions: When is the best time to buy a hardy mum? When I dig up the grass/dirt to plant the hardy mums, will there be a regrowth of grass? How do you pinch a hardy mum?

    Hi Kenya
    Best time to plant hardy mums is in the spring. Buy small plants and see how large they get by fall. To keep the weeds /grass from regrowing, try laying thick layers of newspaper and then 2″ of wood chips on top of the soil, after you plant your mums. It works great. The newspaper will eventually decompose. Pinch your mums in June or when the plants are 6-8 ” tall and again before July 15 before buds begin to form. To pinch-nip out the growth center. Pinching will stimulate more branching and produce a fuller, stockier plant. If you want larger flowers, remove all but 1-2 buds. This will focus more nutrients to the 2 buds that are left producing bigger but less flowers. If you want to plant hardy mums in the fall, see the article above.

    Hi Linda
    It is late to plant them outdoors in colder regions. If you are in zone 7 there is a chance that your mums may or may not have enough time to produce some roots for the winter. Check with your neighbors. Be sure to mulch them well after the ground freezes. You can try to winterover your hardy mums in an unheated garage. Protect the pots by cover them with some type of insulation. The important thing to remember is to keep the roots from freezing and totally drying out. So check the plants periodically during the winter and add a bit of water.

    HI Susie
    It’s too late to plant them in the ground wait till spring. Store your mums in the garage or protected area to keep it from freezing and water occassionally during the winter. If it survives then there may be a chance that it will come back next season. For more info read the above article.

    In fall of 2007 we planted Hardy mums from pots we purchased at the nursery. They did well and in spring of 2008 we saw green foliage under the deadness (for lack of a better term) and the old plant just sort of pulled out of the ground uncovering the new mums. We allowed them to do their thing and by fall these massive mums were 4 feet in diameter and bloomed like crazy. Beautiful. This year the green growth is appearing, however the old dead plants are so large and rooted that when we tried pulling them up the new growth was attatched and its damaging the plants. I know so little about doing this I am sort of stuck. Also, how do I keep them from becoming so huge and taking over my flower bed? Thank you in advance.

    Hi Colleen
    The new growth is attached to the old plant. It’s better to trim the dead stems down to the ground and let the new growth take over. I had the same problem with some of my perennials and end up accidentally pulling out the new growth. I usually dig a small hole the replace the new growth, hoping it will survive. If your plants are too big, you can divide them. If they get too tall, pinch them back several times during the growing season. Pinch them back in June and again before July 15 to produce bushier plants and more flowers.

    I have a mum from my grandfather’s funeral that I would love to plant and care for properly so it lives on in his memory. Right now it is in a plastic planter, but would like to transplant it to the ground.

    It has dark purple flowers, and three plants that go into the dirt. There are no markers in the plastic tub to identify the mum – is this an annual or a perennial?
    I live near Des Moines, Iowa (which I looked up to be zone 5a).
    If someone could tell me how to best care for this plant, I would greatly appreciate it.

    Hi Julianne,
    Sorry to hear about the loss of your grandfather. The mum you have is most likely a greenhouse mum not hardy in zone 5a. You can plant it this spring and let it grow outside but it will not winter over. Sorry.

    Spring blooming mums

    I have a green house in NC and have been using cuttings (Mums)to get more.
    Some of my mums are flowering now. (daisy and some cushion and Bonsia)
    Will these also bloom in the fall?
    Or will they continue to bloom until winter.??
    Is it a good Idea to plant a mum in the spring when they are at least a foot high or higher??
    Thanks

    Hi Todd
    Enjoy your spring flowering mums and after they are done blooming cut the plants back by 1/2-1/3 to control the height and plant them outdoors for fall bloom which is their natural blooming season. Pinch your mums in June and again before July 15 before buds begin to form. To pinch-nip out the growth center. Pinching will stimulate more branching and produce a fuller, stockier plant.

    I moved at the end of last summer and found that I have hardy mums in my new flower bed. I never had a garden before, but I read somewhere that you could use the cuttings after you’ve pinched back the mums to start new roots. I would like to use them to fill in some gaps from a bush I removed, so I placed them in some water and have them in a window that gets morning sun. Should I be doing something else to get them to root? How long before I know if this is actually working?

    Leaf spot disease
    I have Mums that return each year. This year, many of the leaves are getting lots of dark spots that show through the leaves top and bottom. What could that be?

    Hi Kathy
    It sounds like a leaf spot disease caused by a fungus usually prevalent in rainy weather. The leaves will exhibit transparent , brow or black spots. To control it, remove all infected leaves to keep it from spreading. Any major infection should be removed. Mulch around the soil to keep the spores from splashing up onto the plant. If this is a presistant disease (year after year) then start spraying the plants with a fungicide(wettable sulfur or bordeaux mix). Follow manufacturers directions. The fungus overwinters in soil debris, so be sure to clean-up well in the fall.

    Hardy mum wilt disease
    I live in Zone 7 and have had several hardy mum plants in my bed out front for a couple years. This summer I noticed one of them was beginning to look a little funny…the underneath started to die and the tips of the stems were wilting. The whole plant ended up dying. Now another mum plant is doing the same thing. They were both perfectly healthy. The only thing I noticed was an excessive amount of (I think) flies inside of them. Could this have killed my plant and be affecting my other one?

    Hi Jennifer
    It doesn’t sound like the flies would kill the mum. Hardy mums can get Verticillium, Fusarium, Pythium or Rhizoctonia, fungal disease. Symptoms are similar in that they attack the vascular system of the plant interfering with water uptake causing the plant to wilt. If your plant is watered well and remains wilted, then it may have a fungal disease. There’s no treatment for an established plant. Do not replant a hardy mum in the same spot.http://ag.udel.edu/EXTENSION/horticulture/pdf/hyg/hyg-87.pdf

    I planted several mums in my yard about a week ago(I live in NC). They’re in partial shade and a mixture of about 3/4 topsoil, and 1/4 of our local clay soil, with plenty of fertilizer. On some, the flowers are turning brown and the leaves don’t look so great either. Some of the other mums are doing well. They’ve been watered/rained on every other day. Do you know why some are struggling and some are not? Thank you.

    Hi Sabrina
    Sometimes it depends on the variety and color of the mum as to how well they “weather”. Also, at what stage of bloom you bought the mum. One may have been in a more advanced stage than the others. They do need well drained soil and if there is too much water, your mums will have root rot problems. Avoid getting the flowers and leaves wet especially in the afternoon, that can cause some of the browning. You mentioned plenty of fertilizer-did you fertilize the mums? When in bloom, mums should not be fertilized.

    I planted a mum and it died very quikly (in 4 days). I planted it near my sidewalk and an evergreen. The soil looked like clay.What would have caused this.

    Hi JT
    I can’t tell you why your mum died within 4 days. The clay soil would be a major factor. If the soil remained too wet (clay soils hold moisture) then it could cause the roots to rot and the plant to wilt and die. Blooming plants are alway in a more sensitive stage as the roots have to supply not only the leaves with moisture as well as the flowers. So anytime a plant is in stress, the flowers will be the first to go.

    Bugs on mums
    I successfully got my purple mums to come back this year. The one at the end of the driveway is covered in flies. Every time you walk by they swarm everywhere. I am trying to sell my house and am pretty sure that will be a deterrant. I hate to destroy the plant, I have sprayed wasp spray on it, that didn’t work. Any suggestions?

    Hi Allison
    There are several bugs that can infest chrysanthemums; Lace bug, Four-lined plant bug, harlequin bugs and tarnished plant bug. They feed on the foliage causing it to deform and discolor. You can try handpicking the insects, if the infestation isn’t too big. Otherwise, spray the plants with insecticidal soap every 3-5 days for 2 weeks. Be sure to spray the underside of the leaves. Another remedy is to spray with a pyrethrum spray. Spray your plants in the morning and on overcast days.

    How long will they last
    I live in zone 4 (Western WI) and just purchased some mums today. They’re beginning to flower now. I’d like to use them for a portion of wedding flowers for Oct. 24. Do you know how long they’ll last in the pots? Will they continue to flower if I leave them outside and keep them watered until October 24? Any suggestions? I’ve only purchased 2 pots, but planning on getting more. Thank you.

    Hi KK
    Six+ weeks is a long time to keep your mums fresh looking. Buy the rest at a later date and make sure the flower buds are not fully opened-just enough to show color. Store them in a shaded area outside, so they get enough light to continue to grow- no direct sun. Don’t forget to water. Keep them cool, warm temperatures will make them bloom faster. Protect your mums from frost. If cold weather is eminent move them into the garage.

    Hi MJS
    Not much you can do at this time. Some cultivars have a tendency to get taller than others. If you trim them now, you will loose the flowers. Give your plants some support, by tying the stems to stakes. Next season pinch your mums in the spring when the plants are 6-8″ tall and at least one more time before July 15.

    I live in South Jersey and I have a question about buying mums that are already bloomed this early. I was told that if I remove the wilted flowers that new ones will come back, is this true ? I am planting them in the ground in their pots and want to see the blooms when they are planted. I don’t like to buy the ones with closed buds and I’m worried that they won’t make it until Halloween. I could wait and buy ones that are bloomed in October (which is when I usually buy them) but chances are they will be the same ones that are there now. Please help, ths is driving me crazy !

    Hi Michelle
    Once you remove the wilted flowers you can get a few more but don’t expect much. The only blooms that you will get are from the buds underneath the old flower or some of the smaller buds along the stem. These will develop only if the have the right growing conditions-light, moisture, etc. I wouldn’t count on it. When picking a hardy mum, I usually look for healthy plants with half opened buds or buds with some color, this assures me that they will open. Don’t buy plants that are wilted or with brown tips on foliage or flowers. After you purchase your mums make sure that they don’t dry out and keep them out of direct hot sun. This shortens their lifespan significantly.
    I can’t tell you when to buy your mums but I would think you could expect at least one month of bloom from a healthy plant. Hope this helps your sanity.

    Propagate mums from cuttings
    How can you make a sprout off a live mum? I would like to spread mums around and I don’t know how to spread them.

    Hi Tammie
    Cutting are taken in the spring. Take a 3-4 ” piece of tip growth, remove lower leaves and plant in a pan filled with moist perlite. You can also dip the cutting in rootone to promote faster root growth. Place the container in a plastic bag to maintain humidity and keep the container out of direct sun. Cuttings should roots in 4-8 weeks. Once rooted replant in potting mix.

    Hello
    I just bought a few mums today. I live in the Northeast and its the 1st of October.
    Is it too late to transfer them into the flower bed ??
    Do i need to water them in winter ??
    Any other advice and tips are greatly appreciated .
    Thanks a lot.

    HI SB
    Transferring them into a flower bed is a 50/50 chance. See article above. Instead of throwing them out, it is worth a try to plant them to see if they survive. They may not have enough time to establish a good root system to winterover with. Be sure to mulch the plant after the ground freezes to protect the roots.

    MY MUM IS IN A POT. JUST GOT IT YESTERDAY. HOW OFTEN DO I WATER?

    Hi Ramona
    By the time they get to the market, hardy mums are usually pot bound and will dry out faster because much of the soil is used up. When the top inch feels dry, water your mum so that the water drains from the bottom. You can also test for watering by lifting the pot, if it is light, then it needs water. Watering frequency will also depend on weather conditions-on sunny, warm days you will have to water more often.

    My mother brought home a pot of mums only 6 nights ago from Home Depot. I’m in New York, and I was surprised to see that almost every single blossom was in full bloom. They were a lovely dark yellow tinged with orange. I put them on a south-facing window sill that night, and the next morning at about 10am I went to water them, but half of the blossoms had died and the rest of the plant began wilting (in one night!). I watered them and moved them to another window sill, this time on an east-facing window, fearing that the building across the street was limiting sun from the first window. The next day the plants condition had gotten worse. Since, I have rotated it to windows around the house and nothing has helped. We haven’t turned our heat on yet, so days have been reaching 70F degrees maximum inside, with nights creeping to 50 at lowest. I have almost no experience dealing with flowering potted plants. Can you tell me what I have done wrong, and if they can be saved, what I should do? I’ve read through the comments and realized that I should remove the dead material, so I have just done that.

    Hi Claire
    Here is my guess as to what happened to your mum. When you buy them in full bloom, you don’t know how long they have been that way. They could be at the end of their blooming cylce and any little stress will push them right over the edge. These fully bloomed mums have a big root system that doesn’t have enough soil to help support the moisture they require to maintain all those flowers. If you pop out one of the plants out of the pot and look at the roots you will see lots of roots and hardly any soil. It’s been used up. (This also happens with potted hanging baskets). Watering is important is this case. When you water and it immediately drains out, then the roots are not getting enough water, so you need to soak the plant for 1/2 hr. to be sure that they are watered enough. A cool, humid environment is best. You can keep them outside as long as there is no frost, they can tolerate temperatures in the upper 40’s. Indoors, keep the mum away from direct sun, this will also shorten their life span.
    The best way to care for a blooming plant is give them bright indirect light, cool temperatures and adequate moisture. Of course, this varies with certain plants.

    Growing mums pruning tip
    I live in the Shenandoah Valley and, for two years, have bought “starter” mums and grown them in plastic pots. I transplant them in September and they all are doing beautifully. The Mennonites in the area (some own the greenhouse I buy from) have a rule of thumb for cutting back mums: Mother’s Day, Father’s day and the 4th of July. This works like a charm, keeping the mums from getting two leggy and helping them produce an abundance of flowers.

    Sounds like good advice! Thanks!

    My orange mums or turning yellowish a drying out. If I pinch off the dying blooms. Will this make the plant look better or will it kill it.

    Thanks in advance to all.

    Hi Antoinette
    Pinching off the dying blooms will improve the looks of the plant, it certainly will not harm it.

    Hi,
    I live by Denver co. and i just bought 2 beautiful mums for Berlin OH (no tag of what kind) how do i know what zone they are for or what kind they are (hardy?). I guess I will try to winter them in my garage over the winter. Someone told me that they will not come back next year no matter what I do.. Is this correct.

    Hi Edie
    It is a gamble. If you winter your mums in the garage make sure the soil doesn’t dry out completely and the pots are not exposed to freezing temperatures. The article above on hardy mums explains why wintering mums doesn’t always work.

    We received two mums as gifts yesterday. One is a cherry color; the other a “golden color”. We live in the Piedmont of NC. How do we take care of these plants through the winter? Thank you for your help.

    Hi Sue
    I would think you could plant them outdoors and they would survive the winter. Make sure they get enough moisture during the winter. Enjoy them now and plant them after they are done blooming. Remove any dead flowers and place 1-2 inches of mulch around the base of the plant. To further protect them, apply a loose mulch such as straw, evergreen boughs or shredded leaves after several hard frosts. (If you don’t get a frost then skip that step.) In spring remove the mulch and trim any dead foliage back to 2-4 inches above the ground.

    The pot mum, “Point Pelee” is it a perennal or annual flower? Should I plant it now or keep it indoors until spring if it is a perennal.
    Thanks,
    Aces

    Hi Aces
    It depends on where you live. Pelee Mum is hardy in zone 7-10 and can be grown there as a perennial. Otherwise, you need to protect it from freezing temperatures and keep it indoors. In colder climates it is usually treated like an annual and tossed after it is done blooming.

    Florist Mum
    Hi,
    My fiance gave me a potted mum on the day he proposed to me, back on Nov. 23rd. We live in the NW of Montana and in an apartment so I won’t be planting it outside. It’s very pretty with dark purple or burgundy daisy-like blooms. I was just wondering how to take care of it, to keep it as long as possible since it has sentimental value now. I water it about every four days when the soil looks dry. All the blooms have been gone for a long time (which I removed when they died) and the stems and leaves started to turn brown so I cut them back a bit and picked all the dying leaves. It’s still green and starting to get new, bright green leaves around the base. Should I put it in a new pot at some point, maybe with rocks in the bottom for drainage? Should I quit watering it at some point and how do I tell it is going dormant? Thanks, anything helps!

    Hi Dani
    It will be difficult to rebloom this mum indoors. I’m presuming that it is a florist mum which is not hardy(will not winterover) but can be grown outdoors during the summer. Florist mums are usually thought of as being enjoyed and then tossed. Being in an apartment makes it an extra challenge.
    For the plant to go dormant, it needs to be stored in a cool, dark place until spring. Since you have new growth, I would leave it on a window sill and let it grow. Water moderately just to keep it from drying out. You can repot in the spring and when it starts to put on a lot of growth start fertilizing the plant. Chances of it blooming are slim.

    I bought three plants, ester plant (white lily flower), potted-mum Chrysanthemums (yellow-orange flower) and another plant.

    Two of my plants are dying, i guess. Can you please tell me why? I am new to this plant growing.

    The potted mum (Chrysanthemums) gave me lots of flowers and suddenly all the leaves started browning and drying. I cut lot of those brown leaves yet no use. No regrowth. soil is moist and it is kept near window but the plant doesnt look healthy. It has two branches of greeny leaves one branch full of brown-died leaves. another independent plant stem has all the leaves brown except only one leaf. 🙁

    Easter plant (white lily) is also giving me trouble. It gives brown leaves in the bottom of the plant (stem). This one also gave five beautiful white flowers and I cut those flowers off after few days. Why does the leaf become dry and brown.? Will another leaf grow if i cut these brown -dying leaves? Will it give more flowers? Soil is moist and it is kept little bit inside the window (7 ft) but it does get window brightness all day.
    Please help me.

    Hi Hari
    Your mum probably needs to go outside and get more sun. The forced potted mum usually do not last very long once they are done blooming. It may also be suffering from too much water. If you left it in the foil wrapping that doesn’t drain water then the roots are sitting in water and rotting. Best you can do is cut back any dying foliage and plant it outdoors. It probably is not hardy and will not survive winters with temp. below freezing.
    Your Easter lily is done blooming. It only blooms once a year. Now the leaves will slowly start to die back. Make sure it also gets good drainage or the roots will rot and the plant will die prematurely which will result in no flowers next year. You need to plant it outdoors so it will rebloom next year. See article on Saving your Easter lily.

    Wintered mums
    I purchased mums from Lowes in the fall and planted them. I am wondering if they survived the winter? So far they are still completely brown and are not greening up at all. I am in SE Michigan. If they survived when should I expect them to green up? or are they just dead? Thanks.

    Hi Tammy
    If your mums survived, you will see new growth at the base of the plant. In the meantime, cut off all the brown, dead stems. They will not green up. You should see new growth in the next month when the soil warms up.

    We have had hardy mums in our flower bed for about eight years. Each year they get larger and taller. We have only been cutting them back in the spring. We live in Central Indiana. Is it too late to cut them back? How late can I cut them, and how far back is safe?
    Thanks,

    Hi Mike
    No its not too late. Pinch your mums in June or when the plants are 6-8 †tall and then again before July 15 before buds begin to form. Pinch 2-3 inches, no more than 1/3 of the plant. You can then propagate the clippings.

    Pinching mums
    I planted several mums in early May this year, they already start to be very tall and one of them started blooming. Will they grow out of control? I am worried that they may take over my garden. Can I move them in the summer when they bloom?

    Hi Vivian
    I’m not sure which mums you are referring to. You may have something that looks like a mum plant. To get compact, bushy mum plants, pinch them when the plants are 6-8 †tall and again before July 15 when buds generally begin to form. To pinch-nip out the growth center. It’s not a good idea to move them now- wait until the fall.

  49. vivian - June 26, 2010 at 7:09 pm

    Thanks for the comments. The mums are Helen Yoder Garden Mum. When they were planted in early May, they were only a few inches tall. Now they are more than 18″ tall and wide. I did not pinch them as I thought they were new plants. But I probably should have. A few flowers showed up and lots of buds formed. I guess it is too late to pinch them. I will wait until fall to move some of them.

    I read it somewhere that these mums are very aggressive. So I am worried that they may take over the rest of the garden bed. Thanks for your advice.

    Hi Vivian
    Be sure to deadhead the flowers, to extend the bloom season.

    I planted some “hardy” mums last fall in my garden. Most came back this spring but as the summer progresses they are getting very spindly not short and bushy. What can I do?

    Hi Jim
    You need to pinch your mums in June or when the plants are 6-8 †tall and again before July 15 before buds begin to form. To pinch-nip out the growth center. Pinching will stimulate more branching and produce a fuller, stockier plant. Are the plants in full sun? Low light conditions will also make them leggy.

    Heat stress
    Will mums (in Pots) weather the warm summers outside in AZ. I have taken them out of the direct HOT sun and placed them on my covered patio. They seem to be struggling. I am wondering if it is better to over water or under water. I get worried that they are getting hot and i give them more water. It has been explained to me that if I under water it will be to late to recover them but if I over water them I will show brown leaves at the bottom of the plant first, giving me time to recover and back off the watering. Your thoughts. thanks

    Hi Norm
    Your mum plant is struggling in the heat of summer. It is best to keep the soil evenly moist-not too wet or too dry. Keep it in semi-shade area so that it can thrive until you get a cool spell. Make sure the plants are not pot bound or they will dry out faster. Also, avoid black pots as they absorb more heat than a lighter color. Warm night temperatures will also delay bud formation.
    Another option is to plant them in the ground in semi-shaded area and add 2-3 inches of mulch around the plants to keep the soil cool.

    Our dog Maggie pasted away in Sep. 2008. To remember her I planted a dark red mum next to her grave. It’s going on 2 years now and the mum is very small and green. I live in upper Michigan, in the woods,in a marshy area. What can I do to make the plant bigger and flower? The soil is good with no clay. I’ve never fertilized it. It is in a shaddy spot, I’m thinking this is the problem. Thank you for your time and suggestions.

    Hi Sabrina
    Sorry to hear about your dog. You may want to feed the mum with a balanced fertilizer, in addition the shaddy spot is the problem. Mums need full sun the grow and bloom well. If it doesn’t improve after this bloom season, move it to a new location with more sun next spring .

I pinched 8 mums in early July, but left one un-pinched as there are many flower buds. This one mum is now blooming beautifully with dard red flowers. They other pnes start to develop buds. My mums are in a mostly sun location.

    I planted several large mums next to each other last fall and they all grew back beautifully. The only weird thing is that one plant in particular bloomed several weeks ago, and now that those blooms have all turned brown, the others are just beginning to bloom. All of the plants look healthy – no rot or spots on the leaves. Should I pinch off the dead blooms and hope that new buds grow? Is it normal for one plant to bloom/die that quickly before the others have come out?? I’m in upstate NY. Thanks!

    The one mum must be an early bloomer. I would trim off all brown flowers, check under the flowers to see if there are any buds, if so you may get more flowers if not then its done for the season.

    I live in Massachussetts. I bought 6 mums (don’t know if they are hardy or not) from Home Depot to decorate for Fall. I planted 4 of them and left 2 in pots. The planted ones lost their flowers and the potted ones are still vibrant with flowers. I’m going to put the potted plants in the garage for the winter and plant them in the spring.
    Should I trim back the ones in the ground and mulch them now?

    Hi Alex
    You can cut off the dead flowers but wait until spring to trim the stems on the mums. The stems will help capture leaves and snow during the winter which will help insulate/protect the crown of the plant. Keep the plant watered through the fall and mulch 2-3″ around the plant after the ground freezes. With a little luck they may return next year.

    Some perennials will seperate when they have a vigorous growing season. The stems grow tall and a bit weaker tending to fall over when the flowers arive. To avoid this problem, you need to pinch your mums in June or when the plants are 6-8 †tall and again 4 weeks later before July 15 before buds begin to form.

Why don’t these people tell us that when we buy them. I have been buying them for 20 years (well not every year, I’m sure I missed 10 years )and this year I decided I really want to try to take care of my mums, so that they come back every year. If anyone has any tips for me, it will be appreciated. But none the less, I am reading up on them, hoping I can get them to survive this winter.

    Hi Rita
    Mums sold in the Fall are mainly used for decorative purposes. It is best to plant mums in spring, so that they have a whole season to establish a good root system. As for the Fall season, get your mums into the ground asap, to give them a chance to grow some roots so that they can survive the winter. In addition, add 2 inches of mulch around the plants after the ground freezes. Once your plant looses all its leaves, allow the stems remain during the winter. They will capture snow and leaves which will help insulate and protect the crown of the plant. Trim the dried stems in the spring.

      Yes, spring is a better time to plant mums. Most of the mums on the market are sold for decorative purposes, although they can be planted in warmer climates and even in cooler climates, if you get them in the ground early.
      Get your mums in the ground asap and make sure they are watered in well. Leave the stems during the winter so that leaves and snow can accumulate and insulate the crown of the plant. Once the ground is frozen add 2-3 inches of mulch around the plant. Hopefully, it will winterover and return next year.

Any advice how and where you did the transplant here in Minnesota would be so nice. I have been thinking just to maybe cut them back and put them in the garage with a window exposure. And water as needed. My cabin also stays fairly cool downstairs with good light available. How cool do they need to remain? I also have some potting soil available. Location is mid-northern Minnesota west of Duluth for a weather reference. Ground not frozen yet, but I think it would be best to keep them in the pot until Spring. Just because – you know?

Give the soil and bit of water it once a month just to keep the roots slightly moist. Kris

    HI Connie
    It sounds like you’re doing just fine with your mums. I recommend to leave the stems so that leaves and snow can accumulate inside/around the crown of the plant to help insulate it, then cut back in spring. This is important the first year of planting. Once the plant is well-established it may not make much difference either way except is there is a severe cold winter with no snow cover.

    Hi Sam
    Remove the mum from the pot and place it in a hole large enough to accomodate the root ball. Make sure it is planted at the same level as in the pot and water. After they are done blooming cut them back down to 6″ leaving some of the stems to trap winter snow for insulation. Also mulch your mums after a hard freeze with several inches of straw, pine needles or evergreens, the added insulation will protect the root system.

    A friend of mine bought 5 potted mums from Lowes to decorate for a Halloween party. She was going to get rid of them but I ended up taking them in. She cut back two of them with scissors. They are full and have green leaves but the parts she cut seem to be drying out. Two others are full, have a few flowers alive and a lot of dead brown flowers. The last one looks bad. It does not have the fullness like the others thick stems with a few flowers and brown leaves. They are in good pots but they will slide out with lots of roots showing. So I know I will need to do something about that. I live in an apartment in south Texas (near the beach) with a large porch that gets morning and some mid-day sun. I have never taken care of plants like this mostly ferns and palms. Help!! Do they have a chance or am I in over my head. I really want to keep them alive but I don’t know were to begin. Thanks

    Hi Shanel
    Usually, mums are planted into the garden so that they have room to grow. You can try to grow them as potted plants but it may not be worth the effort. If so, repot them in fresh soil. It sounds as if they are root bound-so cut off some of the roots before you repot or place in a larger pot.

    It depends on if your plants survived the winter. Wait a few more weeks and check at the base of the plant and see if there is any new growth. If so, repot them or plant them in the garden. If not then it probably did not make it.

Even though I live in Washington state and it rains quite a bit the mums were dry and in desperate need of some care. I live in zone 7 and would like to plant them in the ground. I gave them a good watering of miracle grow. Should they come back and what else could I do to get them healthy before I plant them?

    Hi Shawna
    Well the miracle grow will not help-that’s the last thing you should do. Stressed and dried out plant cannot use fertilizer, in fact it may burn the roots. The best thing you can do is plant your mum in the ground and water. Make sure the soil is loose and well drained. Once they respond with new growth, then give them a dose of fertilizer.

If I transplant these mums to another location in my yard will they grow back again next year or not? They were made for outside and they are perennial mums. Please let me know if it was wrong to transfer them from one place to the other. Thank You

    Bloom to early
    I have had numerous hardy mums which come back and bloom every year and are so beautiful. I do cut them back in early or mid June so they will not bloom until fall but this year I did the same thing and now have one of my largest plants starting to bloom already. If I cut anything back now will it rebloom or is it too late. What happened to the one plant?

    Hi Linda
    You should have cut them again before July 15th. Sometimes they require two trimmings. The crazy hot weather must have started them to bloom. see heat delay Q&A. I think you might have enough time to cut them back and go for later bloom in the fall-but that is your option and depends on where you live. Here’s what you can do, cut of 1/3 of the plant so that you will get more lateral growth from which new buds will form. It should then bloom later in the fall. Your other option is to let them bloom.

If the plants are growing in temperatures above 90F or night temperatures above 73F, then the mum’s flowering can be affected by heat delay. The heat buds form but will not develop until temperatures cool.
    The flowers may also die from being too dry, botrytis or some kind of stress on the plant.

    I have hardy mums (facing east) along the front of my home in Amarillo, Texas. They are huge and some have already bloomed (I think because of the extremely hot summer speeding up the blooming cycle). The remaining are all full of buds but when you look inside the bush, the leaves are brown or gone altogether. I have sprayed for leafhoppers and treated for snails. However, I now believe I am fighting some sort of fungus. Some of the bushes are separating and sections of the bush are dying. These are established mums (3rd year in place). I have watered every morning because of the 100+ weather nearly all summer. Have I killed them with kindness. Suggestions would be greatly appreciated.

    Hi Irene
    I don’t think you killed them with kindness. The hot and humid environment is ideal for fungal disease. Mums grow in a tight pattern and there is little room for air flow. You can spray the mums with a fungicide to help control the spread of the disease.

    Pruning mums
    August 28th, hottest summer ever in Kansas. I have had beautiful mums on the south side of my home for a number of years. I cut they back Memorial Day Weekend, but now they look tall, scrawny, with brown dying stems and leaves. Afraid the over 100 degrees hot days of summer may have done them in. Is it okay to cut them back now? Will they have time to bloom for October and November. Just heart sickening.
    Thank you for any advice.

    Hi Deb
    Mums can be pruned twice a season if needed sometimes even 3 times. The last prune date is usually mid-July. Your growing season is a bit longer. Since your plants are tall and lanky, cut them back and feed with a balanced fertilizer around the plant to encourage new growth. Hopefully, they have enough energy to grow and bloom.

    I have an event scheduled for September 13 and I need the mums to be in full bloom and look great.
    If I buy them now and they are just buds – how do I care for them. Keep them in the shade or sunshine , water – no water,
    thank you

    Hi Cindy
    Are the mums in a tight bud or are they starting to show color? Keep them in part sun and watered. If they are not showing any color keep them in some sun. Make sure the soil doesn’t dry out. If you let the plant dry out then it will reduce the plants longevity.

    Cut off flower buds
    My overzealous spouse got carried away and cut the tops off of all our well-established hardy mums which were covered in buds and blooms. These were bushy plants a few feet wide and a few feet tall; now they are sorry green stems with very hacked-off tops. And fall is upon us here in Zone 5b.

    Is there hope? Can these plants recover for next year? Is there anything I can do?

    Hi G. Mom
    The plants will recover for next year but I’m not sure if you will have any flowers this year. Give it a dose of 10-10-10 fertilizer to stimulate new growth. Let me know if it blooms this fall.

    Save mums for wedding
    Hello! We live in Iowa and we just purchased 4 large beautiful mums from Costco hoping to use them for our daughter’s wedding on Oct. 15th. They have many buds but show no color yet. What would be the best way to keep them in good shape for the wedding? Can we keep them outside during the day and bring them into the garage at night? Also do we need to fertilize them or just water? Thank you so much!

    Hi Mark
    Six weeks is a long time to keep your mums fresh looking but should work since they are in tight bud. Keep your mums in a slightly shaded area outside, so they get enough light (bright indirect light) to continue to grow.If cold weather is eminent, protect your mums from frost by moving them into the garage. They should not be allowed to dry out to the point of wilting, that will reduce the life span. The plants should be moist but not wet and excess water should drain out from the bottom of the pot. Also, keep them cool( 70’sF )as warm temperatures will make them bloom faster. No need to fertilize the plants.

    Best time to plant mums
    I just purchased 10 pots of hardy mums. They have buds that aren’t out yet. I thought I could plant them now but in reading your blog you are saying not a good time to plant. I live in Flint Mi and will not be here to water for the winter should I return them or put them in the ground

    Hi Linda
    The best time to plant hardy mums is in the spring but you can plant them now. It’s early enough-before frost gets them. Make sure you water and mulch around the plants so they have a chance to establish their roots before winter. There’s a 50/50 chance that they will come back next year.

    Flower buds drying out
    Hi,
    I bought mums 2weeks ago. They had many flowers and few flowers then. but after 10days the buds are drying out. drying is from bud to below. the leaves are good. Though some buds did flower. I kept them in the same pot I bought. They are inside my apartment. get sun for short time in the morning. How should I save them from drying. Pl help me. thank you

    Hi Hari
    Put it outside. Most likely, the mums are not getting enough light inside the apartment to continue to bloom. The buds need bright light to open. Make sure the plant stays evenly moist and does not dry out.
    Diseases such as botrytis, bud rot as well as insects will also turn the buds and leaf tips brown but that doesn’t sound like your case.

    Winterover mums
    My questions are regarding potted mums purchased in September in Zone 4a/3b (located north of the Twin Cities): 1) When should the mums be brought inside to overwinter? Before the first hard freeze? 2) Can they be kept in their pots the following year or will they need to be planted in the ground?

    Thank you!

    HI Gerard
    Bring your mums inside before a hard freeze. You can keep them in the pots just make sure the soil doesn’t dry out completely during winter storage. Check on them periodically during the dormant season.

    Also, as a follow-up question: Since I’m planning on overwintering my mums and my uninsulated attached garage can get below zero on extremely cold nights, I was planning on wintering the mums in the unheated crawl space under the stairs of our split-level house. Temperatures there are probably in the 50s…is that cool enough for the mums to stay dormant? Thanks again!

    Hi Gerard
    Temperatures in the low 50’s should be cool enough, 40’s would be better. Wait until they drop their leaves before you put them in storage.

    i have several hardy mums that i transplanted this spring from pots that overwintered. they all are huge this fall and putting out tons of blooms. the problem is that most of them are blooming deep burgundy and i’m pretty sure that only one or two of them at the most were burgundy the year before. has anyone come across this problem and and suggestions as to why this might be happening?

    Hi Miscooma
    It’s possible that only the deep burgundy mums were hardier and survived.

    Die too quickly
    Good Day,
    I just purchased two beautiful rust colored potted mums for either side of our front door. I love mums. Love Love Love mums. Sadly every year, they die on me pretty soon after I get them. It makes me so sad. I know they require full sun, and on either side of our front porch, they don’t get that full 8 hours of sun they evidently like. Heck, I don’t know if they get even 1 hour! Will they live in my partly/mostly shady spot, or must I move them?

    Happy Fall!

    Hi Ronda
    If your mums are in bloom then the location should be fine. One thing you should keep in mind is that when you buy mums, they are usually pot bound (full of roots) and have little soil to keep the roots moist. So be sure to check them for moisture everyday so that they don’t dry out. Their lifespan is shortened when allowed to dry and wilt. Also if a frost is eminent move them to a protected area for the night.

    I purchased some beautiful yellow hardy mums a few weeks ago. I decided to keep them in doors until the spring to be able to transplant them. They were doing great. However, the bloom has started to look very dull and dried out. I keep them next to a very sunny window. I’m not sure what to do. I live in Arizona. Any help would be greatly appreciated!

    Hi Jenny
    If you have 6 weeks before your first frost date in AZ. then you can plant them outdoors now. It may be worth a try-otherwise they will dry up and die.

    I don’t think it’s the street lights that are affecting the bloom. They need warm temperatures, even moisture and sunlight to open.

    Winterover indoors
    I got a small Ursula Lavender potted mum for a gift, will it survive in the house, do I need to water it any and will it come back in the spring and do I need to transfer it to a bigger pot, it is in a small pot.?

    Hi Martha
    Yes, you do need to water it and keep the soil moist or it will dry up. Your mum will survive for a few weeks indoors. It’s best to grow them outdoors as there is never sufficient light and moisture indoors. They will dry up very quickly, esp when the heat comes on. Best to keep it in a cool spot such as a basement, garage that stays above freezing over the winter.You want to keep the roots from freezing. You can transplant it in a bigger pot because they usually are potbound by this time. If it survives, plant it outdoors in the spring. It may not be worth the effort.

      I bought mums from my daughters school fundraiser in mid september. They were beautiful with many buds. I kept them in their pots outdoors for a month and watered occasionally…they also got alot of rain. Now some have started to shrivel and die…others are wilty. When I took them out of the pots to check, it turns out the roots took up everything and the pots had not been holding water. I have now planted them (october 11th) and watered hoping they will “come back”to their original beauty. Will this happen? If not will they root and come back next spring? I live in northeastern new jersey.

      Hi Julie

      No the mums will not come back to their original beauty. They may perk up a bit. If the winter is mild and roots are mulched at protected they may sprout next spring. It’s really hard to say what will happen.

    Pelee mum is hardy in zone 7-10. You may be able to plant it outdoors in Tennessee (zone 7). Be sure to mulch it well after a freeze to protect any roots.

    I live in Pennsylvania near Philadelphia I purchased a few large beautiful “hardy’ mums and asters at the Home depot.In my zeal to plant these beautiful fall bloomers I didn’t test my soil. My assumption is “hardy ” meant hearty! Within 6 weeks my blooms stopped and all but two straglers have withered up and died. I’m soooo disappointed I wanted them to be gorgeous for fall. My soil is quite poor it has a lot of clay I believe. Home depot will take them back in exchange for new ones. I don’t want a repeat of dead plants. What should I do? The asters are kaput too. Any help is great!

    Hi Leesa
    Sorry you had so much problems with the mums. Unfortunately, it happens a lot. If the soil doesn’t drain well then the plant will not be able to send out new roots to establish itself. Most people leave them in the containers and enjoy them during the fall and discard them. The above article will give you some info on hardy mum care.

      HI Martha
      It’s difficult to say if it survived. Place the plant in a sunny warm spot and continue to water. If you see new growth then it survived. Then transplant it outdoors when the soil warms up.

    Hi all,

    My landscaper just came by, cleared off the cut-down stalks I was using for winter cover and dropped 1-2″ of cedar mulch on top of my just sprouting mums. Will the mums be able to push through or do I need to dig them out?
    Regards,

    Hi Andrew
    It depends on how thick the mulch is. If there is a heavy layer of 2″ or more then, I would move the mulch from where the new growth is emerging to make it easier for the mums.

    Hi Gerri
    Hardy mums are usually pruned twice a season, once in June and then no later than July 15. This is done to control the height and make bushier plants. Since yours have early flower buds, you can either trim them or let them bloom early and then cut them back by July 15 for an additional fall bloom.

    I’m so glad to find your site! I’m a mum murderer. I never pay more than 50 cents for a mum because I know I’m gonna kill it, so I just enjoy it for a few short weeks. That’s sad, isn’t it?

    We just moved to Modesto, CA. I think the heat and being root bound has been the problem. I’m more hopeful since I started reading your posts. My cheap little mum plants look all dried up and dead in their pots. I don’t know how to give them another chance here. I don’t know which varieties I have or if they’re greenhouse grown because I bought them from the hardware store last fall. Should I just trim them and plant them in my yard’s sunny, sandy soil to see if they get new growth in fall? I’ve really got nothing to lose at this point.

    I want to stop murdering these innocent little plants. Help me, Obi Wan.

    Early blooming mum
    I have been googling an answer to this and you seem very knowledgeable. I have a mum, I think the kind is beryl. It really took off this spring and got over 6 inches tall so I cut it all the way to the ground in May. It grew back nice and bushy. Now it already had buds on it and one of them opened yesterday. It has always been an earlier bloomer, usually late July or early August but never this early.

    If I let it bloom now will it rebloom again later in the summer/fall or should I pinch off the blooms now? Thank you for your advice!

    HI Christine
    A lot of plants are blooming early due to the “unusual” weather. Instead of cutting off the buds, I would let it bloom. After it is done cut off the dead flowers, fertilize around the plant and it may bloom again in the fall.

    Mum flower buds not opening
    All of my mums were beautiful when I purchased them. Full of blooms and buds. Some I kept in pots and some I planted in the ground. All get morning and early afternoon sun.

    On all of the plants, both planted and in pots, the buds are dying before they open. Some of the buds open a bit and there are few petals that emerge but they die before they are fully open.

    The foliage is beautiful – very lush. What is happening to the buds? Thank you.

    Hi Jabba
    When a plant is in a stressful environment the flower/bu damage are the first indicators. They could have been overwatered, kept too dry, too much heat or sun. When purchasing mums, look for plants that have slightly opened flower buds; that way you are assured of them opening and lasting longer.

    Hello,

    I live in northern Illinois, on the border of Wisconsin. I bought a bunch of mums from the various home and garden venues around my home. I’ve transferred all of them to large pots–I’m not sure these pots have holes in them, which may be the problem. Come to think of it, the ones that are doing the best are in the brown hanging sacks.

    My white and yellow mums are turned purple and then some of the flowers shriveled up and died. They bloomed beautifully for about 6 weeks–so I’m not sure it’s the pots that matter (or perhaps, they do). I’ve taken off all of the dead flowers (and left the discolored ones). My largest plants still has a ton of unopened buds. Will these still bloom or should I call it is season? We haven’t had a frost yet, but temperatures drops to the 40s overnight. Many of my neighbors still have blooming mums, so I’m wondering what I’m doing wrong.

    i live in a zone 6 planting zone and i had purchased a quite a few hardy mums last fall between the beginning of sept to the end and planted them in the ground in numerous flower beds. i mulched around them for winter and added straw around the base not so much on top of the plants we did not have a really bad winter i don’t think we even had a day below zero. what do you think the plants survival rate of the plants would be good or a total loss?

    Hi Ray
    If you had a mild winter, there’s a good chance that some of the mums will survive esp. in zone 6. As the weather warms up, make sure you remove the mulch and straw. You should see green grown at the base of the plant. Remove/cut off any dead, old stems from the previous season.

    You can try to grow it indoors in a sunny place, not sure how well it will grow. Another option is to give it a rest, let it go dormant and store it in a cool place without freezing temperatures.
