Then carefully dig around and under each plant. Try to retain as much of the root system as possible. Promptly plant 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.
Peonies grow best in full sun and well-drained soils.
Dig a hole large enough for the entire root system. Place the peony plant in the hole so the eyes are 1 to 2 inches below the soil surface. Fill the hole with soil, firming the soil as you backfill, then water thoroughly. Space plants about 3 to 4 feet apart. Apply a 2 to 4 inch layer of mulch in late fall.
