Iowa’s AMES — Peonies can live for up to 100 years if they are properly cared for. Iowa State University Extension and Outreach horticulturists respond to inquiries on peony maintenance, including when and how to divide the plant.
When is the best time to transplant peonies?
The ideal month for peony transplants is September. Cut the peony stems at or just above ground level to start. Next, thoroughly excavate each plant’s perimeter and its base. Keep as much of the root system as you can.
Large peony clumps can be separated now if desired. Section off the clump using a sharp knife. A strong root system and three to five buds each division are ideal.
When transplanting, make sure the hole you dig can hold the peony’s whole root system. Put the division or plant in the hole with the buds 1-2 inches below the soil’s surface. Completely saturate the earth in the hole with water.
Is it necessary to periodically divide peonies?
It’s not necessary to divide peonies on a regular basis. Peonies can be left in the garden unattended for up to 50 years. Large peonies can be divided, though, if you want more plants.
When is the best time to divide peonies?
The ideal month to divide peonies is September. Peony plants can store enough food in their roots for the following year by the month of September. In addition, before winter arrives, the newly planted divisions have a few weeks to settle in at their new locations.
What is the proper way to divide peonies?
Cut the peony stems at or just above ground level to start. Dig the plants up with care, then wash or gently shake off the soil. Section off the clump using a sharp knife. Three to five buds (eyes) and a sound root system should be present in each region. It could take two or more years for divisions with fewer than three buds to blossom.
When planting, make a hole big enough to fit the peony’s root system. Put the peony in the hole with the buds 1-2 inches below the surface of the soil. (Plants may struggle to blossom if the buds are deeper than 2 inches.) As you backfill the hole, compact the soil around the plant as you fill it with soil. then thoroughly rinse. Peonies should be spaced 3 to 4 feet apart.
What is a good site for peonies?
The optimal conditions for peonies are full light and well-drained soil. Choose a planting place where there will be at least six hours of direct sunlight each day. Avoid standing in the shade next to big trees and plants. Compost, sphagnum peat moss, or leaf mold used in significant volumes can typically improve poorly drained soils.
When are peony able to be divided?
Herbaceous peonies (Paeonia lactiflora), which are graceful and fragrant, add a charming touch to gardens in U.S. Department of Agriculture zones 3 through 8. Peonies are one of the first perennials to bloom in the early summer, and you can divide them whenever they’re dormant. The optimum time to divide peonies is in the fall, when the plants have gone into dormancy, as working early-spring soils can be challenging in all of these zones due to residual winter cold. However, early spring is also a successful time to divide them.
Can you cut a peony for cuttings?
Before resetting, most roots benefit from a trim. To prevent congestion and encourage new growth, trim roots to lengths of approximately eight inches.
The peony family is diverse. hybrids have some “roots that may be separated from their rhizome and planted to produce new eyes are known as adventitious roots. After two or three years of growth, these root cuttings can be spread out in rows at a depth of two inches and lifted in the fall.
Knives, scissors, and spades used to cut rhizomes, roots, and foliage should all be sterilized. Fungi and viruses can be killed by a 10 percent or 70 percent solution of rubbing alcohol and water.
Utilize a dipping solution of a “Bordeaux mix, an alternative to fungicide dust, is a mixture of copper sulfate and hydrated lime. Both call for the wearing of thick gardening or rubber gloves.
On fresh plants, don’t compact the soil too firmly. You run the risk of breaking or pushing eyeballs deeper than two inches. When in doubt, overfill the hole and place your eyes as close to the surface as possible.
If you cut the stem sufficiently deep, you can use cuttings to spread soft-stemmed perennials like peonies. Peony stems emerge from “eyes that appear from rhizomes just below the soil’s surface. The most dependable methods of propagating these perennials are by rhizome cuttings and seedling growth. Unlike plants developed from seeds, rhizome cuttings typically blossom one to two seasons after planting and always give rise to a plant that is identical to its parent. For flowers in the spring, take cuttings in the fall.
Fill planting holes with a bushel or two of adjusted soil by mixing equal parts garden soil, peat moss, compost, and manure. For every bushel of filler, mix a small amount of bone meal, superphosphate, or another low-nitrogen fertilizer. For each, create a hole that is one foot wide and two feet deep “To determine how many you will have, divide or plant additional plants. Unused holes can always be filled with dirt. On either side, provide each plant about three feet of room.
- If you cut the stem sufficiently deep, you can use cuttings to spread soft-stemmed perennials like peonies.
If peony roots dry out, the plant will be set back and may not bloom the following season, so pick a day when the soil is damp rather than dry to start. In the fall, after removing the summer mulch and trimming back the dead foliage, dig peonies. Lift the entire root ball by making a deep cut underneath the roots with a spade or garden fork all the way around. Once the ball has been raised, use a hand cultivator or trowel to remove as much dirt as you can. If you are excavating more than one peony, focus on one plant at a time.
Remove any remaining dirt from the roots, fleshy root, and rhizome with care. On the top part of the rhizomes, look for the tiny eyeballs. Avoid breaking any buds at any costs. These stem bases serve as the foundation for fresh peony growth, and once broken, they cannot regrow.

Use a sharp knife to cut each rhizome into numerous pieces. Each component needs a set of roots and three to five eyes. Apply an anti-fungal powder, which is readily available at most garden centers, to each portion of the rhizome. If the peony you are dividing is particularly huge or old, use a spray bottle to keep the roots moist as you cut the rhizome.
Trim older or damaged roots on divisions and discard any pieces that are rotted or discolored. Eliminate soggy roots; they can contain nematodes or root rot. Spread roots while suspending the rhizome over the hole and amending the soil in the holes. When the hole is filled, position the rhizome so that the eyes are only a few inches below the surface. More than two inches of eye burying will probably prevent blooming. In southern growth zones, plants should be placed no deeper than 1.5 inches. Water the new plant thoroughly once the hole has been filled.

Yes, peonies can be multiplied by cuttings if the stem is cut sufficiently deep.
Does the peony spread?
No, peony won’t naturally grow more plants or spread out. One day you may realize that your peonies have grown rather large and have spread out quite a distance.
If you want to grow more peony plants in this situation, dividing them is your best option. This is the finest approach to propagate herbaceous peonies and a way that you may aid in it.
Peonies can’t actually be encouraged to grow or anything like that. Simply put, it’s better to hold off on taking any action until the peony plant has grown larger.
Dividing peony plants is the only way to produce more of them. Although this method isn’t inherently difficult, you’ll want to become familiar with it so that you can carry it out correctly.
To get more peony plants, read on to find out how to divide existing ones. This will enable you to plant peonies in several garden locations if you so want.
What happens if peonies aren’t pruned back?
In the winter, you don’t really need to do anything to or for your herbaceous bush peony plants. However, if you discover that you neglected to remove the stems in the fall, you still have time to do so.
Herbaceous (bush) peony, such as the intersectional Itoh peonies, eventually lose their leaves and stems when the plants hibernate for the winter. The stems will tumble to the ground and turn “mushy,” and the leaves will begin to decay. That is normal. The plant’s roots are not perishing; instead, new shoots and stems will appear in the spring. People may panic and believe their peony has perished, but this is simply the bush peony’s natural development cycle.
Be careful not to cut any exposed peony ‘eyes,’ which are typically pink or crimson buds and serve as the stems for the following year, while cutting off peony stems that are close to the ground. Put the stems and leaves in the trash after disposal. Peony stems and leaves shouldn’t be composted since they can harbor botrytis, a fungal disease, especially in moist environments. Each peony plant’s surrounding area should be cleaned up.
Most places don’t require mulching peonies. If you mulch your herbaceous bush peony plants, make sure to take it off in the early spring to avoid burying the roots too far. Years of mulching or applying bark dust around bush peony will eventually cause the roots to be buried too deeply, which could lead to fewer spring blooms. Just an inch or two of soil should remain above the roots of herbaceous bush peony after you remove that.
Additionally, it is normal for a mature peony’s crown to gradually heave up through the ground and display some exposed “eyes” in the winter. Don’t worry, peony plants enjoy the harsh winters.
Tree peony leaves must be removed from the ground and branches when they start to degrade. A tree peony’s branches are left hanging, barren and naked for the winter, rather of being chopped down in the fall. Don’t worry too much if you or a helper cuts a tree peony down to the ground and you panic or feel dejected. It’s likely that the roots have grown deeply enough to support spring branch growth. It might grow into a magnificent, revitalized tree peony in two or three years. I’ve seen it happen, so I know. In contrast to bush peony, tree peonies prefer more soil on top of the roots. Try adding a few inches of soil around the base of the trunk of a tree peony if it has lost its vigor. Yes, it is exactly the reverse of what is suggested for bush peony.
You can go outside again after the snow melts and it’s nice out to work on any “lost” stems.
Are peonies to be pruned back?
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.
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!
Can peony be rooted in water?
No, the fragments in water won’t grow roots; they will instead perish. For herbaceous peonies, the tuberous roots are the only part I am aware of that can grow from root divisions. I believe that all tree peonies are grafted or rooted cuttings. But they don’t simply have roots in the winter; they also have woody stems all year.
Best places to grow peonies?
The peony has the fattest, most delicious petals and rich green foliage, making it outrageously attractive when it is in bloom. From spring to summer, savor stunning floral displays. Learn how to care for, grow, and plant peony.
About Peonies
Peonies are a perennial that will steal your breath away every year. The plants may even outlive you—some have been reported to survive for at least a century.
When Is Peony Season? When Do Peonies Bloom?
Depending on your location and the kind you are planting, peonies bloom from late spring to early summer.
You may extend the peony season across several weeks and take use of those magnificent blossoms for as long as possible thanks to the abundance of nurseries that provide early, midseason, and late blooming types.
Peonies may thrive as far south as Zones 7 and 8, and they are hardy to Zone 3. The key to success in the majority of the United States is to provide full light and well-drained soil. Peonies even enjoy the winter’s coldness because it helps their buds grow.
Types of Peony Flowers
You can pick from six different varieties of peony flowers: anemone, single, Japanese, semi-double, double, and bomb. The odors of different plants also differ; some, like “Festiva Maxima” and “Duchesse de Nemours,” have seductive rose-like aromas, while others have a lemony scent or none at all.
Where to Plant Peonies
When planted as a low hedge or along sidewalks, peonies make excellent sentinels. As majestic and dignified as any flowering shrub, the peony’s bushy cluster of attractive glossy green leaves lasts all summer before turning purplish-red or gold in the fall.
Peonies work nicely with irises and roses in mixed borders and blossom alongside columbines, baptisias, and veronicas. Plant pink peonies with blue Nepeta or violets, then surround white peonies with yellow irises and a froth of forget-me-nots.
Peonies are not overly picky, but you should pick your place carefully because they dislike disruption and do not transplant well.
Although they can survive in partial shade, peonies like full sun, and they flower at their best in an area that receives 6 to 8 hours of sunlight per day.
Because of its huge flowers, peonies can become top-heavy in severe winds. Therefore, provide shelter. (If necessary, stakes can be used to hold them up.) Planting too close to trees or bushes will cause peony to compete with them for nutrients, sunlight, and moisture.
Grow peony in rich, wet, humus-rich soil that is deep, fertile, and well-draining. pH in the soil should be neutral.
When to Plant Peonies
As long as they are planted correctly and become established, peony plants require minimal upkeep. However, keep in mind that they do not adapt well to transplanting, so you should consider this when choosing your planting location.
- Plant peony in the fall: in the majority of the United States, in late September or early October, and even later in the fall in Zones 7 and 8. Your planting zone can be found here.
- If you need to move an established plant, the fall is the ideal season because the plant will be dormant.
- About six weeks before the ground freezes, peonies should be planted.
- While planting peonies in the spring is absolutely a possibility, the results aren’t always favorable. They often trail behind plants planted in the fall by roughly a year, according to experts.
How to Plant Peonies
- Peonies are typically offered as divisions of a 3- or 4-year-old plant, bare-root tubers with 3 to 5 eyes (buds).
- Peonies should be placed 3 to 4 feet apart to allow for enough air circulation. The development of disease can be facilitated by stagnant, damp air.
- In a sunny area, dig a generously sized hole that is about 2 feet deep and 2 feet wide. The inclusion of organic matter in the planting hole will improve the soil. Add additional compost to the soil to improve it if it’s sandy or heavy. Add about a cup of bonemeal to the ground. Find out more about soil improvements and getting the soil ready for planting.
- The roots should be positioned in the hole just 2 inches below the soil’s surface, with the root’s eyes facing upward on top of a mound of soil. Avoid planting too deeply! Choose early-blooming species, put them approximately 1 inch deep, and provide some shade in southern states.
- Backfill the hole after that, being careful to prevent soil settlement and a 2-inch root burying. Gently tamp the ground.
- Plant a container-grown peony no deeper than it was when it was in the pot.
- When planting, give everything plenty of water.
How to Care for Peonies
Young peony take time to develop, just like children. In order to establish themselves, blossom, and flourish, they typically require a few years. They eventually leave home on their own, fully grown and adjusted… No, that’s just kids, I suppose.
Peonies benefit from gentle neglect. They don’t require digging and dividing every few years like the majority of perennials do.
- Don’t use any fertilizer. Before planting, till the soil thoroughly while adding compost and a small amount of fertilizer.
- Early summer, after the peonies have flowered and you have deadheaded the blooms, is the ideal time to apply fertilizer (such as bonemeal, compost, or well-rotted manure) to a soil that is deficient in nutrients. Keep fertilizing to a few years at most.
- assist the stems Peonies’ stems, which occasionally are not strong enough to hold their enormous blossoms, are the only part of their structure that may be considered weak. Think of structures that allow the plant to grow through the middle of the support, like three-legged metal peony rings or wire tomato cages.
- Peony blossoms should be deadheaded as soon as they start to fade, cutting to a sturdy leaf so that the stem doesn’t protrude through the foliage. To prevent any infections from overwintering, trim the foliage to the ground in the fall.
- Avoid covering peonies with mulch. For the first winter following planting, you can VERY LOOSELY mulch with pine needles or shredded bark when the winters are bitterly cold. In the spring, get rid of the mulch.
Peonies bloom between late spring and early summer, but by planting a variety of cultivars, you may arrange your garden for a succession of blooms from mid-May to late June. Here are a few options:
- ‘Early Scout’ has red solitary flowers that open incredibly early.
- “Firelight”: very early-blooming, single, pale-pink flowers
- ‘Karl Rosenfield’: double, midseason bloomer with substantial crimson blooms
