How to grow Common Garden Peony

Written by the GardenDecoded editorial team · Last reviewed 21 July 2026 · Written for UK gardens · How we research our guidance

Planting

Plant in autumn, and get the depth right: the pink buds on the crown should sit no more than 3-5 cm below the surface. Planted deeper, the plant grows leaves and never flowers. Prepare the ground properly with compost first, because peonies dislike being moved and can stay put for decades.

Pruning

Deadhead after flowering to stop energy going into seed. Cut the foliage down to ground level in late autumn and clear it away rather than composting it, which reduces carry-over of leaf disease.

Propagation

Divide in early autumn, cutting the fleshy crown so each piece has three to five buds and some root. Divisions often take two or three years to flower properly, so it is worth doing only when necessary.

Pests and diseases

Peony wilt is the significant disease: shoots blacken and collapse at the base, usually in a wet spring. Cut affected stems out below the damage and dispose of them; good air movement and autumn clearance reduce recurrence.

Value to wildlife

Single-flowered forms give bees access to the pollen and are worked heavily. Fully double flowers are largely useless to insects.

Notes

Heavy double flowers flatten in rain, so put supports in place in spring before the growth is tall. A newly planted or newly divided peony sulking for a season is normal, not a fault.
