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.
How should tree peonies be cared for over the winter?
The plant’s stems will be safeguarded if you wrap it in burlap in the late fall if you reside in a chilly environment. Don’t remove the roots of tree peony. If this does occur, there shouldn’t be any long-term harm, and the plant will quickly recover.
Are leaves lost by tree peonies?
Perennial peonies called herbaceous peonies fade back to the ground every year. The plant stems push up in the spring while the roots remain dormant beneath the dirt. Woody, deciduous shrub peonies are called tree peony. They shed their foliage in the fall, but unlike herbaceous peony, their woody branches do not die back to the ground. Itoh peonies are a hybrid cross between herbaceous and tree peonies; while they do die down to the ground in the fall like herbaceous peonies, they exhibit tree peony-like growth and flowering traits.
Before they became beloved ornamentals, tree peony, which are native to China, were prized as a therapeutic plant. A tree peony can reach a height and width of up to five feet (1.5 meters) in around ten years and is a larger, woodier relative of the ordinary herbaceous peony. They are widely coveted for their huge, prodigious blooms, which can reach a diameter of up to 10 inches (25+ cm).
These blooms occur in single or double shapes and bloom from late spring to early summer. They are great cut flowers. Tree peony do not produce the sweet honeydew sap that herbaceous peonies do, which is what draws ants to their flower buds.
How come my peony tree is dying?
The peony plant may have bud-blast, a condition when the flower buds don’t open, as a result of anything that stresses the plant. This problem is brought on by infertile soil, planting too deeply, young plants, excessive shadow, dryness, and cold weather damage, which is usually brought on by late spring frosts.
Should I prune a peony tree?
Especially if planted in the spring or later in the season, water often during dry periods throughout the first year to aid establishment. Deep-rooted established tree peony shouldn’t require routine watering after the first year because of this.
Feeding
Apply a general-purpose fertilizer, such as Growmore, at a rate of 70gm per sq m each spring to encourage healthy growth and flowering (2oz per sq yd). Then, to maintain moisture and control weeds, mulch the area with a 10cm (4in) layer of garden compost or well-rotted manure. However, avoid piling mulch up against stems as this could cause them to rot.
Deadheading
Since the majority of tree peony are hybrids and frequently fail to produce viable seed, dead blooms can be removed with secateurs after flowering. Any seed set would in any case not reproduce accurately, and the offspring would have various bloom colors.
Caring for older plants
Tree peony have a very long lifespan and typically grow into larger clumps over time. However, the red and yellow variants of the small-flowered Paeonia delavayi are rather vigorous, and the stems might need to be thinned (see Pruning tree peonies).
Minimal pruning is necessary for tree peony. Simply clip off any flowering shoots in the summer or, if preferred, in the fall after the seeds have been collected, just above the new growth on the stem.
Over many years, stems may become lanky. In order to promote bushier growth, trim them back by a third in the fall after the leaves have fallen.
Paeonia delavayi f. lutea and P. delavayi are two tree peonies that often grow more robust, erect stems. Once the plants are established, trimming back some of the oldest stems at ground level in the fall helps to regulate their size (i.e. they are flowering freely each spring).
Growing from seed
Both hybrids and species, such as Paeonia delavayi, can be grown from seeds, but the latter will not reproduce itself. Although you might produce some intriguing new hybrids, they frequently fall short of the quality of their identified variety (cultivar) parent. However, starting from scratch can still be exciting, and every now and then, you’ll come upon a self-sown seedling that you might want to continue developing on.
- Once the seed pods start to separate in the late summer and early fall, gather the ripe seed. The seed is black and fertile. Red seed should be rejected because it hasn’t been fertilized and won’t sprout.
- As soon as the seed is collected, plant it 2.5 cm (1 in) deep in containers with John Innes seed compost.
- Place the compost in a cold frame or other protected area outside, such as at the foot of a house wall, and lightly cover with grit.
- Make sure the compost is not allowed to dry out over the summer and keep rats out.
- Two cold periods are required for peony seeds, followed by a warm phase. The seeds are doubly dormant, which means that after the first winter of cooling, the root emerges the following spring, but the stem and leaves do not sprout until the second winter.
- Up to five years may pass before the seedlings reach flowering size.
Other propagation options
If a flexible stem can be bent over, layering is rather simple. Before the stem produces a strong enough independent root system to be detached from the parent plant, it often takes two to three years.
The majority of tree peony are propagated commercially through grafting, but this method is not frequently employed by home gardeners because it requires a lot of skill to achieve good success rates.
- poorly budged Even if the plant was purchased in bloom, tree peony might take up to four years to establish itself and blossom. In a shady location, tree peony have a tendency to flower less frequently. To make the plant receive more light, trim any overhanging branches, or think about moving it. Although established plants may withstand brief episodes of dryness, extended droughts can have an impact on the following season’s flowering. When there are extended dry spells, cover the plant’s base with mulch and provide water.
- Frost injury
- Late frosts have the potential to harm flower buds and developing foliage. Buds and leaves that have been damaged may become dark and not open. Use a fleece during chilly evenings.
- Shallow planting might promote the rootstock’s suckering. The rootstock is typically P. lactiflora, which has bright reddish shoots as opposed to the drab light red color of tree peonies’ shoots. If you’re unsure, look at if the shoots are coming from below the graft union (visible as a slight bulge close to the base of stem). Use a sharp knife to remove the suckers as soon as they emerge at the point of origin.
- The only significant illness affecting peonies is peony wilt (grey mould), which causes drooping and dieback of the leaves as well as buds and blooms.

What distinguishes peonies from tree peonies?
Tree peony are actually small bushes, not trees, and they bloom in May and June with stunning goblet-shaped flowers. Tree peonies are higher and maintain a constant framework throughout the year, in contrast to herbaceous peonies, which die back every year.
How to grow tree peonies
In the fall, plant tree peonies in wet, well-drained soil in a location that receives some to all of the shade. Except for those that remain quite moist over the winter or are on the acidic side, most soils are good. When buying, plant them somewhat deeper than the soil level in their container.
Cut off any suckers that you notice at the base of your tree peonies because they are growing from the rootstock and will look different from the rest of the plant.
Is tree peony a perennial plant?
Inquiries concerning tree peony maintenance in UK gardens are frequent.
What makes it the best? When should tree peonies be planted, and how should they be cared for? Below, we share our wisdom and expertise on how to take care of these magnificent plants.
The UK Tree Peony Care
Date of Planting The best time to plant new trees and shrubs in your yard is in the fall. It is simple to dig because the dirt is damp. Additionally, it is warm below the surface, which will provide the greatest possible start for your seedlings. Autumn weather, which is typically wetter and gradually turns colder than other seasons, is best for plants entering into dormancy for the winter.
If plants are planted in the autumn, they will have built a root system by the following spring and will be ready for the more challenging variable hot, cold, and dry weather conditions in early summer. The seasons will soon change, the days will get shorter, pumpkins will be available in stores, and your garden will experience a period of transition.
A common illustration of a plant that grows best in the fall is Tree Peonies. Before the ground freezes solid, usually in late December or early January, plants planted in the autumn gradually grow and settle their roots.
The Tree Peony, also known as Moutan, is a deciduous shrub that originated in China and is not, despite its name, a tree. The Tree Peony is a bigger variety that keeps its exquisite wooden stem or bark throughout the winter, in contrast to the more typical herbaceous peony that dies back in the winter.
Despite having a delicate appearance, Tree Peonies are remarkably tough and bloom for 50 to 80 years. These powerful plants have a remarkable past; they were initially cultivated in China 2,000 years ago and have survived tremendous climate variations.
Tree peonies are prized for their exquisite flowers, and for the finest blooms, they should be planted in full light.

The Tree Peony Attitude
Get your tree peony settled and acclimated before the winter frosts and cold because they are notorious for not wanting to be moved about much. Planting in the fall allows the Tree Peony ample time to grow roots before the ground freezes, which is important because Tree Peonies acquire their nutrients from the roots. This will assist in promoting springtime development. Although tree peony are robust, long-living plants with stunning spring blooms, they grow slowly until they are well-established. Tree peonies can thrive in either direct sunlight or light shade. Give your tree peony plenty of room to grow, don’t place it too close to other plants, and don’t move it once you’ve planted it. Tree peonies can grow up to 2 meters in length and keep their stems through the winter. However, after planting it, you must give it some time to grow.
Location, place, place
In a protected area with good drainage and full sun to moderate shade, tree peonies thrive. The soil must be loose and deep. Mulching the soil after planting is advised to maintain moisture levels and stop soil from drying up.
We grow Tree Peonies in our own yard beneath Japanese Acers in lush, healthy soil. Give the Tree Peony some room so that air may flow around it without being overly exposed and subjecting it to harsh prevailing winds.
Vanity and grooming
Pruning is not very necessary for Tree Peonies. If seeds are wanted, cut back just above the new growth in the summer or the fall to remove flowering shoots. After the leaves have fallen in the autumn, cutting old stems off at the base will promote bushier growth. To promote new flowers, feed the peony in early autumn and once more in late spring.
