Herbaceous peonies need to be severely pruned back to the ground in the fall. Pruning is unnecessary for tree peony. In the fall, all that is required is the removal of the faded seed heads. In the autumn, resist the urge to remove the withered leaves; instead, let it fall off naturally. Tree peony should not be severely pruned because they are sometimes grafted onto herbaceous peonies.
Try to avoid walking on the herbaceous types’ newly emerging buds when weeding borders.
Peonies occasionally develop suckers at the plant’s base. David Hurrion discusses what to do with them in this passage:
How to propagate peonies
Herbaceous peonies can be multiplied in the fall through division. Lift the plant with a garden fork after trimming back the wilted foliage. Cut off pieces of the crown with a knife after removing as much of the garden soil as you can. There should be plenty of root in each part and at least three buds. Replant as soon as possible in the garden.
Try not to split tree peonies. Alternatively, you might be able to attempt sowing seed or stacking a flexible stem.
Growing peonies: problem solving
Ants are drawn to the peony buds. It’s common to witness ants swarming around the buds. They won’t harm the plant, so don’t be concerned.
Peony wilt is by far the most prevalent issue. The stems decay as a result of this botrytis. Planting peonies too closely together is best avoided. Remove any leaves with dark spots on them to help stop the fungus from spreading. To prevent reinfection in spring, remove all the foliage before trimming back herbaceous plants in the fall.
In this Gardeners’ World video clip, Carol Klein provides a practical guide on identifying and treating peony wilt as well as advice on how to clean secateurs to prevent reinfection:
Can peonies 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 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.
- 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.
- Lift the entire root ball by making a deep cut underneath the roots with a spade or garden fork all the way around.
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.

Most Frequently Asked Questions
Peony stems can be multiplied by cuttings if the stem is cut sufficiently deep.
To lift the entire root ball, use a spade or garden fork all the way around.
Within a season or two of planting, peonies blossom, and each plant is identical to the parent.
Yes, cuttings can be used to reproduce soft-stemmed perennials like peonies as long as the stem is cut sufficiently deep.
Yes, peonies can be multiplied by cuttings if the stem is cut sufficiently deep.
Can you root peonies 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.
Can a broken stem be used to grow a peony?
Since peony plants are notoriously picky, you can’t just go out and buy another one. A newly planted peony plant may not bloom for many years. Therefore, you are at best attempting to revive a peony plant that has already perished due to peony damage.
The plant’s stalks should be examined first while rescuing peony plants. Any stalks on the plant with broken stems should be removed. These can be composted or discarded. You cannot start a new plant from a peony plant’s stalks since they cannot be rooted. You can leave intact any stalks that merely have harmed leaves on the plant.
Do not become alarmed if all the stalks need to be removed or were eliminated as a result of the incident. This will have an impact on your peony plant, but it doesn’t mean the plant can’t recover.
Checking the tubers is necessary after you have evaluated and fixed any stalk issues with the peony plant. You should be concerned about the tubers that peony plants grow from. The tubers will survive as long as the damage is not severe. Rebury any tubers that have come loose from the soil. But since peony tubers need to be close to the surface, take careful not to bury them too deeply. The tubers should self-heal and totally recover for the following year if they are replanted correctly.
The only significant peony damage that can happen is that the plant might not bloom for a year or two. It won’t automatically forgive you for allowing major issues like this to arise in the first place just because it totally recovers.
Peonies are actually highly robust despite their petty nature and unpredictable behavior. Fixing damaged peonies shouldn’t be a source of stress if your peony plants have sustained damage due to an accident because there is a good probability they will recover.
Peony plant issues do arise, but once they do, learning how to repair the damage will make recovering peony plants simple.
Do my peonies need deadheading?
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.
Do peony proliferate?
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.
Do peonies prefer shade or the sun?
- Keep plants neat by deadheading and prune as needed (herbaceous only).
- When peonies become congested and produce fewer blooms, divide the plants.
- When the blossoms feel like soft marshmallows, cut the stems for bouquets. Water should contain Miracle-Gro for Fresh Cut Flowers.
When the peonies blossom, you can finally start to feel the arrival of summer. Around Memorial Day, when spring bulb flowers are starting to fade and summer blooms are beginning to emerge, these stunning perennials bloom profusely. Peonies are resistant to deer and rabbits, which is useful for gardeners who frequently experience issues with animals eating their plants. Peonies are frequently seen blooming despite years of neglect if you drive through old cemeteries or abandoned farmsteads. That is because to how simple peony are to grow!
How to Choose Peonies
Peonies come in four different varieties. They are forest peonies, tree peonies, herbaceous peonies, and intersectional peonies, in the order of blooming time. Herbaceous peonies, which thrive in zones 3–7, and tree peonies, which flourish in zones 3–9, are the two most popular varieties. Herbaceous plants often reach heights of two to three feet and spreads of two to four feet. With some types reaching heights of 7 feet, tree peony are more closely related to tiny shrubs. The type of peony you plant will depend on where you live and the style you’re going for because all peonies require similar maintenance. The focus of this paper will be on tree and herbaceous peony.
When to Plant Peonies
Fall is the ideal season to plant peonies. This is often when peonies purchased from a catalog will be delivered. It’s okay to plant peonies when you see them flowering and for sale in containers in the spring.
Where to Plant Peonies
Peonies require at least 6 to 8 hours of sunlight every day, though in zones 8 and 9, some shade from the sweltering afternoon sun is beneficial. Additionally, picking a location with sufficient air circulation is crucial to avoiding fungal illnesses.
How to Plant Peonies
In somewhat damp, well-drained soil, peonies thrive. Dig a hole, take the plant from the pot, and plant container-grown herbaceous peonies (the kind you buy in pots) so that the top of the root ball is level with the earth (any deeper and the peonies will not bloom). Fill up the area surrounding the plant by combining the discarded soil with an equal amount of Miracle-Gro Garden Soil for Flowers.
Before planting bare root herbaceous peonies, give them a brief dip in a basin of water to rehydrate them. Create a planting hole that is big enough to fit the roots, mix the soil as previously mentioned, and place a mound of the blended soil in the middle of the planting hole. Place the roots atop the mound and let them fan out and descend. Using the remaining blended soil, fill in the remaining portion of the hole, making sure that the “No more than 1 to 2 inches of soil should be present around the plant’s eyes (or growth buds) in order for it to bloom.
Deeper planting is required for tree peony. Unless they are grafted, peonies should be planted in the same soil combination as above, 2 to 4 inches deep at the crown (where the roots meet the stem). Check the label to see if the plant has been grafted, and then plant it such that the “The plant’s graft union, where the grafted top and rootstock are united, is located 4 to 6 inches below the soil line.
How to Stake Peonies
Peony stems are prone to toppling over after it rains, and the blossoms can become big and heavy. For herbaceous peonies, the best approach is to cover each plant in a peony cage in the spring, before the leaves begin to sprout (picture metal supports with rings for the flowers to grow up through). This is far more effective than attempting to hold each flower stalk separately, and it also looks nicer than wrapping the entire plant in string and cinching it in like a belt.
One stake can be used to stake tree peonies. Place the stake next to the stem in the ground, and then use a piece of twine to loosely secure the plant to the stake.
How to Water Peonies
When planting, give everything plenty of water. When the spring foliage begins to emerge and the flower buds start to show, give the plants another drink. Although peonies do not have a thirst, they will benefit from watering during dry spells for a year following the first planting.
How to Feed Peonies
Your peony will benefit from a powerful combination of care that includes excellent soil and the ideal plant food. Give peonies the nutrition they require by feeding them Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in addition to the soil improvements indicated above for stunning color and more flowers than unfed plants. Peonies should be fed twice a year: the first time, right after they emerge in the spring (when the new shoots are 2 to 3 inches tall but before the flower buds are pea-sized), and the second time, in the middle of the growing season (about three months after the first feeding), to help them develop sturdy roots before the arrival of winter. Make sure you adhere to label instructions.
How to Help Prevent Problems with Peonies
Although mostly fuss-free, peonies occasionally experience fungal issues. Browning and failure to open flower buds are symptoms of botrytis. Brown patches on leaves are a symptom of some fungus illnesses. Infected blooms and leaves should be simply pruned off and disposed of (do not compost) in order to control these problems. Additionally, keep the plants neat, remove old foliage at the end of the season, and deadhead spent blooms. Peony blooms occasionally draw ants, but they won’t hurt the plants, so you can ignore them. (Contrary to popular belief, peonies do not require ants to blossom.)
How to Prune Peonies
Cut back each flower stalk on herbaceous peonies once all of the blooms have faded to just above a leaf, low enough so that the stem doesn’t protrude above the rest of the leaves. Unruly tree peony can be trimmed either in the spring or the fall (right before plants go dormant). However, any stems you trim back in the fall will not blossom the following spring (as you will be cutting off the flower buds). After blossoming in the spring, you can prune. Anytime you choose to prune, be careful not to take more than one-third of the plant with you.
How to Divide Peonies
It is ideal to leave tree peony alone (undivided) so they can flourish for many generations in the garden. If the clumps have become too large or the flowering has slowed, herbaceous peonies can be divided. Herbaceous peonies can be divided by digging up the entire clump and rinsing it off to reveal the plant’s numerous roots and eyes (or buds). Leave as least one large root and three to four eyes per clump after cutting the plant apart with clean, sharp pruners. Replant, adhering to the bare root peony planting directions above. The plants might or might not flower the first year after dividing, so keep that in mind.
How to Cut Peonies for Bouquets
Timing is crucial. Buds should feel roughly as firm as a soft marshmallow when squeezed, which is known as the “soft marshmallow stage.” Examining the bud’s coloration is another method for determining when to cut. The majority of the bud’s exterior should remain green, but you should be able to make out approximately half an inch of the flower’s vibrant petals. Although cutting the flowers at this point lessens the possibility of bringing ants inside with them, it is still advisable to inspect the flowers before bringing them inside. Plants should open up when stems are placed in a vase of water. For longer-lasting blooms, change the water every few days and apply Miracle-Gro for Fresh Cut Flowers (vs. water only).
