We are often asked about tree peony care for UK gardens – what is the best aspect? When is the best time to plant tree peonies and how to look after them. Below we share our knowledge and experience of caring for these stunning plants.

Tree Peony Care UK – When to Plant
Autumn is the key time for planting new trees and shrubs in your garden.  The soil is moist, making it easy to dig. It is also warm below the surface and will give your plants the best possible start. The weather in autumn tends to be more consistent than other times of year – wet and gradually turning cold, which is ideal for plants going into dormancy over winter.

Perfect for Japanese gardens, tree peonies are royalty in the flower world.

Flamboyant Flowers are produced given the right conditions

If planted in autumn it means by the following spring your plants will already have put down a root system and have established themselves before the more stressful changeable hot/cold/dry weather conditions in early summer. Soon enough the days will be getting shorter and pumpkins will be in the shops and your garden will go through a transition phase along with the season.

Tree Peony Care – Plant now for best results next spring

Tree Peonies are a classic example of a plant best planted in autumn. Plants planted in autumn gradually establish and settle their roots before the ground freezes solid generally in late December/January. Here at Paramount Plants we are delighted to have sourced an impressive selection of these rare to find large tree peony shrubs. All are of flowering age with flamboyant blooms in spring and they are all looking to go to a fantastic new home.

The Tree Peony (despite its name) is not actually a tree but a deciduous shrub originating from China where it is known as Moutan. Distinct from the more common herbaceous peony that dies back in winter, the Tree Peony is a larger version that retains its elegant woody stem or bark throughout the winter.

Tree Peonies may look delicate but they are surprisingly hardy and will keep blooming for 50 to 80 years. These mighty plants have a remarkable history; first grown 2,000 years ago in China and exposed to harsh extremes of temperature, they are surprisingly hardy shrubs.

At Paramount Plants, our selection this year includes more mature specimens than you will usually find in the UK, with some already 80cm in height.

Tree Peony Care UK – Planting Guidelines:
Follow our simple guidelines when planting your Tree Peony and you will be rewarded with a long-standing shrub that will add a glamorous flourish to your garden!

The Tree Peony Temerament – Notoriously not liking to be moved around much, get your tree peonies settled in & acclimatised before the winter frosts and cold. As Tree Peonies get their nutrition from the roots, planting in the autumn gives the Tree Peony enough time to grow its roots before the ground freezes. This will help encourage new growth in the spring.
Tree peonies are long lived, hardy plants with spectacular spring blooms but are slow growing until well established. Tree Peonies will grow in full sun or partial shade.
When planting your tree peony, make sure to give it plenty of space and don’t plant it too close to other plants and don’t move it once it’s planted. Tree Peonies become quite large (retaining its stem throughout the winter) some up to 2 metres. You must however give it time to get established once you plant it.

Location, location, locationTree Peonies do best in sun to partial shade in a well-drained sheltered location. Soil must be deep and loose. Once planted, mulching of the soil is recommended to keep up moisture levels and prevent the soil from drying out.

In our own garden, we grow Tree Peonies in rich /fertile soil beneath Japanese Acers. Allow enough space for the air to circulate around the Tree Peony without it being too exposed and battered by strong prevailing winds.

Primping and preening – Tree Peonies are pretty low-maintenance and require minimal pruning. You can remove flowered shoots by cutting back just above the new growth in summer or in the autumn if seeds are desired. Removing old stems down to their base in the autumn after leaf-fall will encourage bushier growth. Feed the peonies in early autumn and again in late Spring to encourage new flowers.

Two-tone flowers are common.
