In Midwest landscapes, peonies are a mainstay. They produce consistently well in the garden and are simple to grow. However, those of us in extension are frequently swamped with calls, emails, etc. when they do not blossom well. Failure to bloom could be caused by a number of factors.
Buds Don’t Appear
The following are some potential reasons for the absence of buds, which is typically the case:
1. Too much shade around the plants. To bloom successfully, peonies require a minimum of 4-6 hours of direct sunlight.
2. Recently transplanted or divided. If transplanted or divided in the late summer, peonies rarely, if ever, bloom well the following spring. Sometimes it takes plants 2 to 3 years to reestablish themselves sufficiently in their new location to blossom successfully.
3. inserted roots too deeply. Peony buds should be positioned during planting 1 to 2 inches below the soil’s surface. Nobody can explain how they can tell if something is 2 inches or 4 inches, but they can! A peony may have lovely foliage but few (if any) flowers when it is planted too deeply.
4. Excessive fertilization. No matter the location, peonies that receive too much nitrogen rarely flower effectively. Nitrogen favors foliar growth over floral growth.
5. Too big of clumps? According to some sources, huge, aged clumps might not bloom effectively. Nevertheless, I have observed a number of sizable plants in the Midwest that appear to bloom nicely every year. A clump wouldn’t stop blooming until it was several decades old, in my opinion. In order to rejuvenate a clump that is too enormous or perhaps too old, it is simple to divide the plant in the late summer.
Plants are too young, point six. If a cluster can be too old, then there is a chance that it can also be too young. Despite the fact that most peony sold nowadays are not normally produced from seeds, some dedicated gardeners do succeed in doing so. When planted from seeds, plants mature and eventually flower in roughly 4 to 5 years.
7. Cutting down of foliage too soon. If the plant’s foliage is removed in July or August, the plant will become weaker and produce fewer flowers.
Buds Appear, But Don’t Open
Other potential reasons of buds that emerge but do not open include:
1. An abrupt freeze. The flower buds may be harmed or destroyed by a strong freeze in May (like the one we experienced last year). Fortunately, it doesn’t occur frequently.
2. Additional severe weather situations. Very dry summer weather may damage plants and cause them to produce fewer blossoms the next season.
3. Fungal ailments Rarely, especially in cool and wet conditions, the flower buds are attacked by botrytis blight or other fungi. The best prevention methods are removing the damaged leaves at the conclusion of the growing season and the dead buds in late spring.
4. Pest insects. On rare circumstances, flower buds may be harmed and distorted by thrips or other insect pests, which would reduce flowering. Since the harm is frequently done early in the season, insecticides are typically ineffective.
5. Underweight. In most Iowan soils, this is another another rarity. Poorly growing (weak, spindly, yellowish, or “off-color”) plants lack the strength necessary to bloom (but may set buds). It would be advantageous to transplant into a more advantageous area and apply mild fertilizer after establishment.
I’m done now. The most frequent causes of peony not blooming are cultural (planting in too much shade and planting too deeply). Always keep in mind that peonies are resilient and frequently endure for many years in “not so perfect” settings. However, beware if they don’t bloom one year—everyone will notice!
What happens if peonies fail to bloom?
Your peony could not experience enough cold during the winter if you reside in a warmer location. For peonies to form buds and bloom, a specific quantity of cold weather is required. It’s possible that your peony just receives the slightest amount of cold weather to for the buds to form but not enough to cause the last few flowers to open. Make careful to create an environment that might add a little bit extra cold if you think this is your issue. Do not mulch or cover the area where your peony is growing throughout the winter.
In the winter, make an effort to remove any obstructions that might be keeping the wind from your peony bed. Even though it might seem paradoxical, if you reside on the cusp of how much cold a peony requires to completely flower, this might be the extra bit of cold your peony needs.
Your peony needs your patience. Despite the fact that she is finicky, she is well worth the catering so that she can appreciate her flowers.
How can I make my peony produce more buds?
After being moved or planted from nursery stock, a peony may take a year or two to adapt to its new location and bloom. Plant peonies in full light and at the proper depth for most types. Consider shifting the plants if the location is too shady for your peonies in order to promote blossom output. The best location, however, offers some relief from the heat of the day because a little afternoon shade can assist extend flowers once they have opened.
The garden’s soil fertility is another thing to take into account. In order to boost the likelihood of blossom production, try feeding your peony with a liquid fertilizer in the spring.
For peonies to bloom, cold weather is also necessary. You might observe that your peonies generate flower buds that never open if you reside in a warm area. Don’t mulch or cover peonies over the winter, advises Gardening Know How, to cool them off if they become too warm during the cold weather.
Your peony will repay you with abundant flowers and may live for many generations if given good care.
Why are my peony buds still closed?
In full sun, peonies bloom at their best. Plants that are partially to heavily shaded may not be strong enough to provide the developing buds with enough sustenance. The outcome is that the malnourished buds do not fully mature. Peonies that are growing in light to moderate shade should be moved to a sunny location in September.
Fungal Disease
Peony buds may become infected with fungi-related illnesses such Botrytis blight. Buds that are infected wilt and turn brownish-black. The spring months are when fungus illnesses are most prevalent and chilly and rainy. The best method for preventing Botrytis blight and other peony diseases is sanitation. In the fall, remove foliage from peonies at ground level. Destroy and remove the sick plant material from the region.
Freezing Temperatures
A late freeze may have harmed the blooming buds. Although the plants themselves can withstand a mild frost, the buds are more vulnerable to damage from the cold. Sadly, there isn’t much that can be done to prevent this issue.
Exactly how long does it take a peony to bloom?
Peonies are the ideal plants for Grow-Through Supports. Early in the spring, install them so that stems can develop through the grid.
First-year blooming peonies are uncommon. Three years are frequently needed before you see a profusion of blossoms. However, as the plants begin to bloom, you may anticipate a lifetime of lovely flowers. Rarely do peony plants need to be divided. Fall is the best season for separating clumps if they grow too big for a place or if you want to share the plant with a friend. Trim the plant’s foliage, then carefully dig it up from the ground. Cut portion of the plant into pieces with a sharp knife, being careful to leave behind ample clumps of roots with at least three to five eyes per clump. Replant the original plant in its original location, being careful not to damage any of the very brittle roots or leave any significant air spaces in the planting hole. Water until you are certain that the earth around the roots has settled and the moisture has reached the bottom of the hole. Plants divided in the fall may not bloom the next spring, but they will resume their typical behavior the following year.
All that a peony needs for health is an annual dose of organic all-purpose fertilizer and a top-dressing of compost. If you mulch your flower beds, make cautious not to get mulch on the peonies’ bases. Mulch causes the plant to act as though it has been planted too deeply and will result in few, if any, blossoms.

There are several peony types available today, ranging from time-honored ancestral favorites to novel hues (peach, coral, and yellow), intriguing flower shapes (spiders, singles, and semi-doubles), and various heights and blooming periods. Tree peonies, which bloom earlier than herbaceous peonies, have larger flowers, and may grow up to 6 feet tall, might also be something you want to try cultivating.
A special reminder for gardeners in hotter climates: If peonies receive some shade during the hottest portion of the day, the plants will be more resilient and their blooms will stay longer. In warm climates, peonies are questionable and maybe difficult to grow. Consult a reputable local gardener or your nearest garden center to learn if they may be grown in your area.
The ideal types for luring pollinators have just one or two rows of petals.
How can you ensure that peonies bloom all summer long?
You’re hosting a dinner party and have purchased or cut a number of peonies that are still in the bud stage. What do you do when the buds haven’t bloomed the day before your party? Trim the stems and place them immediately into warm water to hasten the process. Place the flowers in a warm area with direct sunlight, vase and all, and check on them occasionally. You can move them to the desired location after they begin to open.
With our suggestions, you can put off wilting flowers as long as you can. These five suggestions should each help your cut peonies thrive for a few extra days. Additionally, if you want them to endure even longer, plant peonies in your garden this year so you may take advantage of them all season long!
How often should peony be pruned?
Fall is the time to trim the plants to the ground after they begin to turn yellow or brown. The best time to prune the plants is in the early fall or after the first frost. Cutting peonies in the fall aids in eradicating foliar diseases and lowering infection the following season. Simply remove and discard all of the growth at the soil level.

Do I need to prune my peony?
Peonies actually don’t require much pruning, but like any shrub, trimming can help to maintain overall health and the management of pests and diseases. Peony pruning can assist in keeping the plant in form.
Why won’t my flower buds bloom?
When a disease called flower balling occurs, flower buds typically grow but never open. But why is this happening? The outer petals become saturated by the cool, rainy weather, which is followed by the sun’s drying and fusing of them into a hard, papery shell that stops the bud from opening.
Will peonies bloom if ants are absent?
Do ants actually aid in the blooming of peonies? Ants “tickle the buds to assist the flowers open,” according to myth about gardens. There is a beneficial relationship between peonies and ants, but it’s not what you may imagine. The tale of peony and ants is presented here, along with advice on how to bring peonies indoors without attracting ants.
We celebrate the breathtakingly gorgeous peony blossoms in the late spring. But those of us who have peonies in our gardens might also note the ants’ appearance, particularly in or near the base of the flower or on unopened buds.
Are Ants Harmful to Peonies?
Let’s answer this initial query first. No. Without a doubt. Avoid sweeping those ants under the rug or, even worse, using insecticide!
Ants are not only NOT dangerous, but they are also a prime illustration of biological mutualism. The ants guard the peony from aphids, thrips, and other harmful insect pests while the peonies supply nectar (food) for the ants.
Do Peonies Need Ants to Bloom?
The persistent misconception is that ants are necessary for peonies’ buds to open. You may have heard that for peonies to blossom, ants must “tickle the buds” or “lick the sugar.”
As with most mythology, this claim may have once had a glimmer of reality, but we haven’t yet seen proof of it. (We also appreciate that this legend keeps ants and peonies alive while letting nature run its course.)
Why Ants Are Attracted to Peonies
Simply put, the sugary drops (nectar) that are present at the base of the green sepals that encircle a peony bud are what attract ants. Due to the presence of amino acids, lipids, and other organic substances in addition to sugars, this is an excellent food source for ants.
The peonies ARE NOT being eaten by the ants. A scout ant leaves a pheromone or odor trail on her journey back to her colony after finding nectar on a peony. The scout informs other ants at the nest of the food supply. The recruited ants then return to the nectar-filled peony blossoms by following the olfactory trail.
In return, the ants offer some defense for the plant! The ants attack other bud-eating pests while they are consuming the nectar by stinging, biting, or acid-spraying them before tossing them off the plant in order to preserve their food source.
The ants are also transient. The ants will leave the peony flower once it has bloomed and move on to look for other food sources.
Again, even if there are ants present (for example, if you live on a rooftop), the peony blossoms would still open.
How to Get Rid of Ants on Peonies Before Bringing Indoors
While we appreciate our garden’s pink, crimson, and traditional white peonies, we also like bringing their beauty and smell inside. But how can we prevent bringing ants inside as well?
There are several approaches:
- When the dew is still thick and most of the ants are not yet present, cut the peony early in the morning. Turn the peonies upside down while holding them by the stem just below the flower (to prevent their heads from breaking off). Give the stems directly above the flowers a few solid taps. This aids in removing insects and spiders. Apply the correct amount of force for the stem.
- Watch the ants emerge after dipping each peony bloom in a large dish of chilly water outside. They won’t be able to crawl out if the dish is overfilled. To avoid picking up more ants, gently shake/tap the water off the flower and place the stem in a prepared vase. The water in the dish can then be returned to nature, along with the ants.
Cutting the peony flowers before the buds fully open is yet another technique used by expert growers. To get the peony’s buds to open indoors, you must clip it while they are at the “marshmallow stage” (see photo above).
