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 peony be grown from a cutting?
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.

- 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.

Yes, peonies can be multiplied by cuttings if the stem is cut sufficiently deep.
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.
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.
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.
Can leaf cuttings be used to grow peonies?
Pick healthy peony cuttings that are five to six inches long to begin with.
Only the top two leaves should be included in each cutting, and any unwanted foliage should be removed.
Once winter has passed, bring them inside for propagation or store them in a cool greenhouse until spring.
Dig a hole about a foot deep and stretch the roots out when it’s time to plant your peony cuttings.
What is the time required for cuttings to root?
Take cuttings of hardwood in the winter or early spring. At this time of year, deciduous plants—those that shed their leaves every winter—have none. Therefore, unless the buds open, water loss is not a severe issue with these cuttings. It may take two to four months for roots to grow on hardwood cuttings, which are more challenging to root than softwood cuttings. Some shrubs, such forsythia, privet, and willow, respond well to the procedure. Hardwood cuttings can also be used to propagate needled evergreens, but water loss must be minimized.
Preparing Deciduous Hardwood Cuttings
- Pick a sturdy stem.
- Remove a portion of the stem that has grown throughout the summer (depending on species, it may be 1-2 feet long).
- The cutting should be trimmed as follows:
- Start at the stem’s base and make a cut right below a node (Figure 4).
- Draw a line 2 inches above this cut using a pencil. In the rooting mix will be the stem’s section between the cut and the line (Figure 5).
- Make a second cut 2 to 6 inches above the first one, ensuring sure that at least two buds are present in this section.
- To prevent them from expanding throughout the roots process, remove the buds from the bottom 2 inches of the stem.
- By slicing two 1-inch pieces of bark from the stem’s base on the opposing sides, you can injure the cut. Make a deep enough cut to reveal the green layer underneath the bark, but not so deep that the stem is severed in half (Figure 6).
- The stem’s lowest inch should be treated with rooting hormone before being inserted into damp rooting mixture up to the pencil line. Wrap it in the rooting mixture firmly.
- From each stem, two to five cuttings might be possible. If the stem is still long enough, repeat steps three through six. The base and top ends of the cutting should always be kept separate in your memory. The end of the cutting that goes into the rooting mix should always be the base, not the top.
- Depending on the facilities and equipment available, there are presently two possibilities.
- Put the pot in a plastic bag like you would with herbaceous cuttings and place it in a warm area if you don’t have a cold garage with a heating system. The buds will open in two to three weeks, but the plastic bag should maintain a high level of humidity around the leaves and stop excessive water loss. Ensure the rooting mix is moist but not soggy, that the pot is in a sunny location, and that it does not overheat.
- Every two to three weeks, look for roots.
- As with softwood cuttings (Step #8), acclimate rooted cuttings to warmer, less humid circumstances.
Preparing Needled Evergreen Cuttings
Hardwood cuttings are a common method of propagating needled evergreens. These cuttings are handled differently from hardwood cuttings of deciduous plants since they still contain leaves (needles).
- Use only the shoot tips, and lengthen the cutting to 6 to 8 inches.
- The bottom 3 to 4 inches of the cutting should be free of needles. Trim the remaining needles so that they barely cover the palm of your hand to prevent water loss (Figure 7).
- Drawn a knife along the stem’s bottom inch on both sides, wounding the base of the cutting (Figure 8). Don’t split the stem; just cut into it. Apply rooting hormone to the stem’s bottom inch, then insert the stem’s remaining two inches into the rooting mix, being careful not to let any needles touch the mix’s surface. the mixture around it firmly.
If the room is well illuminated, the potted cuttings may be placed in an unheated space with a heating element to warm the rooting mix. If not, place the pot and cuttings in a warm, well-lit area, just as you would with cuttings from deciduous hardwoods. For these cuttings to successfully root, light must be provided. Once every month, check for roots. The growth of roots may take three or four months. Adapt rooted cuttings as previously mentioned.
