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.
How are peony divided and replanted?
Peonies can be left in the garden unattended for a long time. But on occasion, it’s important to relocate established plants. To improve flowering, move peonies that are sheltered by tall trees or shrubs to a sunny location. The peony may need to be relocated in order to redesign a perennial bed or border. Plants that are large and robust can be dug up and divided for further growth.
The ideal month for transplanting established peonies 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. Replant the peony right away in a sunny, well-drained area.
Large peony clumps must be divided in a number different ways. Shake the clump carefully to remove any loose soil from the root system after you’ve dug up the plant. Section off the cluster using a big knife. Each division needs to establish a strong root system and at least three to five buds (eyes). Smaller divisions will take longer to mature into beautiful plants.
The optimal conditions for peonies are full light and well-drained soil. Choose an area that receives at least six to eight hours of direct sun each day when choosing a planting site. Avoid standing in the shade next to big trees and plants. Compost, peat moss, or leaf mold used in significant quantities can typically improve poorly drained soils.
When planting a peony, make sure the hole is big enough to fit the plant’s root system comfortably. With the buds one to two inches below the soil’s surface, place the peony plant in the hole. (Peonies frequently don’t bloom successfully if the buds are deeper than two 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 three to four feet apart.
Apply a four to six inch layer of mulch over the newly planted peonies in the late fall (mid-November to early December). Pine needles and weed-free straw are great mulching materials. Mulching keeps the soil from repeatedly freezing and thawing in the winter, which could lift the plants out of the ground. Early in the spring, before growth starts, remove the mulch.
Peonies that were transplanted might not bloom well the first spring. However, by the third or fourth year, the number of flowers should increase quickly.
Can peony plants be divided?
Whenever the plant is dormant, peonies can be divided or moved. In the early spring, if robust growth hasn’t yet taken hold, they can be separated. Even if leaves haven’t started to form on branches that have emerged above the soil, doing so won’t hurt the plant. Keep the fresh divisions of peony moist after transplanting them in the spring to help the plants establish themselves before the summer heat.
When should peony be transplanted?
The optimum time to transplant peonies is in September, when they have finished growing for the summer and are beginning to hibernate. However, you may also dig out the entire root ball in the spring and plant it before the plants begin to sprout new growth for the year. Peonies will probably be too stressed out to survive if disturbed at any other time of the year.
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.
When peonies blossom, should they be pruned back?
After peonies blossom, you shouldn’t prune them because the leaves work hard all growing season to gather energy for the plant. However, Pangborn advises deadheading peonies after they bloom.
To reduce the chance of disease transmission, always prune spent flower blossoms with clean, sharp pruners.
Pangborn continues, “Letting the old flowers stay can lead to fungal growth on the plant, in addition to being ugly.” In an effort to prevent disease from spreading, it is also preferable to remove any stems that are deteriorating during the course of the season.
How frequently can peony be split?
What time of year is ideal for transplanting and dividing peonies? Peonies hardly ever need to be divided, so you can leave a healthy clump of plants alone for ten or more years. Peonies only need to be divided if you wish to add more plants to your landscape.
After division, they take a while to recover, and they might not flower for an entire year. Divide peonies in the fall, when the foliage starts to naturally die back but before it gets too cold. Peonies have clumps of tuberous roots that can be divided into individual plants. It’s not a good idea to divide peonies in the spring because it could stunt the fragile development.
Peonies should be deadheaded, right?
One gardening activity that has several advantages is deadheading peonies. Look at these!
- Increasing Plant Quality These hardy perennials may concentrate their energy on growing the plant itself as they don’t have seed heads or discarded blooms to worry about. This might comprise:
- expanding the tuber
- storing up energy for the coming year
- Putting down stronger roots
- Cleaning the Garden
- Once the peony plant has finished blooming, the unattractive part can be removed by simply snipping away the spent flower heads. Keep the greenery to help you conserve energy for the following season.
- Simple, quick, and satisfying
- Peony deadheading is a quick, simple, and satisfying yard task. When you next just have five or ten minutes to spend in the garden, this project is ideal.
- Future Blooms will be larger
- Do it even though it’s unlikely you’ll see more peony flowers this year. Peonies will produce more and better flowers in the future if deadheading is done.
- Increasing the Plants’ Compactness
- Our peonies are allowed to grow until they die back in the fall, so removing the deadheads helps the plants become a little more compact. This gives us some room in the garden to grow other flowers in front of or behind them, such as hyacinths, sunflowers, or zinnias.
Do you know of any more advantages to deadheading peonies? These are my favorites and make spending a bit more time with these plants worthwhile.
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 grown from 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 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.
