Try to retain as much of the root system as possible. Promptly replant the peony in a sunny, well-drained site. Division of large peony clumps requires a few additional steps. After digging up the plant, gently shake the clump to remove loose soil from the root system. Using a sharp knife, divide the clump into sections.
Peonies perform best in full sun and well-drained soils.
When selecting a planting site, choose an area that receives full sun. Avoid shady areas near large trees and shrubs. Poorly drained soils can often be improved by working in large amounts of compost or peat. When planting peonies, dig a hole large enough for the entire root system. Place the peony plant in the hole so the buds are 1 to 2 inches below the soil surface.
