Hort Zones 4–9, Dappled Light to Full Sun. Rich Soil with Good Drainage, Neutral pH
In zones 4-9. tree peonies thrive. They require great soil drainage and to be planted deeply.
First, tree peony ought to be planted in areas with few competing trees or plants with their roots. Tree peonies should be spaced 5 feet apart. Plan ahead, though, as tree peony dislike being moved. Keep in mind that your plant grows slowly and will take some time to fill in this space. Tree peonies should be spaced 5 feet apart.
Second, tree peonies require neutral pH and compost-rich soil. They should be planted in an area with good drainage because, like all peonies, they cannot tolerate having their feet wet.
Third, although though they can survive in direct sunlight, tree peonies prefer diffused light. Your tree peony would prefer dappled sunlight throughout the day, or morning sun and afternoon shade. This will increase the amount of sunlight reaching your tree peony while also extending the flower’s life. If you choose to plant your tree peonies in full sun, you might want to use wax paper umbrellas to keep the flowers from fading. You should also keep a close eye on the soil’s moisture level to ensure that your tree peony doesn’t dry up. The varieties with more petals will endure more intense sun than the varieties with fewer petals.
All peony require a pH that is neutral, rich soil, and good drainage. You want to mix equal parts sand, clay, and compost to get a sandy loam soil. Wet feet are intolerable to them. Avoid planting in low-lying places where water collects, and exercise caution when growing near sprinkler or irrigation systems.
Which setting is ideal for a tree peony?
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.

How should a tree peony be cared for?
No garden should be without the majestic, long-lasting woody shrubs known as tree peonies. Some types have plants that can produce fragrant flowers up to 10 inches in diameter and grow to heights of 45. Tree peonies are hardy from Zones 4 to 8, do well in the Northeast and Midwest, and flourish in climates with cold winters and hot summers. Tree peonies can be forced into dormancy by gardening in Zone 9: remove all foliage in November, leaving the woody stems, and do not water or fertilize. Hopefully, this will cause the plant to develop blossom buds.
Tree peonies may take three years to develop and begin blooming, so they are not a plant for the impatient gardener. Also keep in mind that it could take several seasons for a new plant’s flowers to bloom to their full potential. Having said that, there is nothing quite like a Tree Peony in full bloom; it is a breathtaking sight.
Before they blossom, Tree Peonies require some time to acclimate; it’s not uncommon for a plant to hold off until its third spring. Additionally, the first spring following planting, Tree Peonies may take longer to emerge from dormancy. Although your plant might appear to be dead while its neighbors are coming to life, it will soon reawaken.
Light/Watering: Flowers need some light protection from the sweltering afternoon sun. In China and Japan, little parasols are used to screen the plants from the sun. Plant tree peonies where they will be shielded from the winter and summer winds that can dry them out. Once established, Tree Peonies are exceptionally drought tolerant. Avoid overwatering plants, and keep them away from automatic irrigation systems. Prior to heavily watering, allow the soil to dry to a pH of 4. The roots will be killed by excessive watering, which is a common cause of failure.
Tree peonies require fertilized soil with a pH that is somewhat above neutral or close to neutral. When planting, add a few handfuls of lime if your soil is acidic. Remove the green plastic ribbon that is wrapped around the stem’s main portion before planting the plant at the depth specified by the ribbon. In order to stimulate the scion to develop its own roots if the ribbon has become dislodged, plant the top of the graft union, which is visible as a bulge on the main stem, approximately 46 below the soil’s surface. In the spring, topdress plants with an inch of aged manure or compost. During the growing season, foliar feeding with fish emulsion is beneficial.
Pests/diseases: On rare cases, you might discover a boring insect-caused hole in the wooden stem. Using a thin wire or by just cutting out the troublesome part, you might be able to kill the larva in the tunnel. Like Herbaceous Peonies, Tree Peonies may contract fungal infections that result in leaf blackening and wilting. As soon as unhealthy foliage is seen, it should be removed. In the fall, make sure to pick up any plant pieces that have fallen. Spray with a fungicide early in the spring and repeat the treatments for a few weeks if fungal diseases start to be an issue. Deadhead flowers regularly and avoid letting dropped petals get stuck in the plant or on the ground.
Companions for Tree Peonies are Hellebores, Alchemilla, Leucojum, Epimedium, and Siberian Irises. Underplant with bulbs that bloom in the spring if your plants have a tendency to be leggy.
Pruning: Unlike their herbaceous siblings, Tree Peonies should never be cut back to the ground. After plants have flowered, remove any broken or damaged stems by pruning. Once your plant has matured and is thriving, you might wish to make a small opening in the center to promote flowering on the taller stems and improve airflow. When Tree Peonies are grafted into Herbaceous Peony roots, the rootstock will occasionally send up a shoot from the plant’s base. These need to be taken out right away.
Dividing/Transplanting: Tree Peonies do not require division, and it is impossible to do it with numerous plants. When dormant, young plants can be transplanted; when digging the plant, try to keep as much soil around the roots as you can.
End-of-Season Care: After a deadly frost, remove all leaves, including leaf petioles, and dump it elsewhere, not in the compost pile. Mulched new plants should also have burlap or another material wrapped around them to block winter winds in the coldest climates.
Topdress plants with an inch of old manure or compost in the early spring. Keep an eye out for symptoms of a fungus infection and administer treatment as necessary. Remove any shoots that appear from the rootstock.
Mid-Spring: Due to their heavy blossoms, certain types may require assistance. To increase airflow, thin out any foliage that is too densely packed inside the plant.
Avoid overwatering in the late spring. Deadhead blooming promptly, and take out old flowers and petals from the garden.
In the summer, water plants only when the earth has dried to a depth of four inches. Fish emulsion feeding of the foliage is preferred.
Fall: Tree Peonies are woody shrubs; do not cut them back. After the first frost, remove all foliage; do not compost. Mulch newly planted vegetation and vegetation produced in colder climates, and if brisk winter winds are predicted, wrap vegetation in burlap or another windproof material.
How much sunlight do tree phlox require?
It’s crucial to start with robust nursery stock and place a fresh planting in a location where it will grow because peony of all varieties can be perennials that live for exceptionally extended periods of time while also requiring little maintenance.
Every kind of peony requires:
- pH of 6.5-7 indicates fertile, well-drained soil that is mildly acidic to neutral. Never put in a peony in a wet spot or one where there is long-term standing water.
- Peonies of every variety will flourish in direct sunlight. Herbaceous and intersectional peonies require at least 6 hours of direct sunlight per day to flourish well. Tree peony grow vigorously and do well in full sun, but growing them there has the drawback of having flowers that fade very rapidly.
- In regions with diffused sunlight or an eastern exposure that receives morning sun and afternoon shade, tree peony will also thrive and produce flowers. The flowers will stay longer, but growth will be a little slower than in the full sun.
You can still grow lovely peonies if you garden in an area with heavy clay soils, depleted soils, and/or very acidic (low pH) soils as long as you take the right procedures to amend the soil in the new peony planting area. In order to give the peony with long-term nourishment, this basically means changing the pH of the soil to the proper level, creating looser, more permeable soil in places of thick clay, and adding enough organic material to deficient soils. Spending a little time and effort now can result in years of gorgeous flowers. We hope the video and illustrated step-by-step instructions below will help you establish the best area for planting peony. Send us an email at if you have any queries.
How to create a fresh peony bed for planting in the fall in an unimproved or lawful area, step by step:
If you’re planting peonies in a new garden space, pick a spot that gets six hours of sun per day (tree peonies will also grow well in dappled shade, but if you are planting herbaceous or intersectional ponies, select a full sun location.) Peonies also need a well-drained environment as a basic requirement.
Make sure the soil in the garden bed is deep enough to support the vast root system of a peony. If the soil is rocky, don’t worry about it; just avoid planting where there are only a few inches of soil above a boulder or rocky ledge.
Our soils in New England are frequently sandy and rocky, as well as having low levels of calcium and phosphate. The native soil in our region has a pH between 5.0 and 5.5, which is far too low for good peony production. Fertility can be increased by amending deficient soils. It’s always a good idea to have your soil tested so you can determine the baseline fertility and mineral levels in your soil.
Peonies should be grown in raised beds or mounds in thick clay soils with poor drainage. Making raised beds can enhance many garden areas.

Should peony be planted next to your home?
Is it true that ants are required to open peonies, or is this just an urban legend? Does anyone have a firm response to this? There is a lot of debate on the internet.
According to my own observations, you do require the ants to open the bud, at least until a few petals are visible. Ants are drawn to peony whether or not they are required. So I advise setting your peonies outside of the building. You will get an infestation if your plants are too close together. Not that I have any firsthand knowledge or anything…
Peonies aren’t particularly appealing to deer and rabbits, since we’re on the subject of animals. If those pests are a concern for you, plant without worrying about them getting devoured.
