When is the best time to transplant peonies?
September is the best time to transplant peonies. Begin by cutting the peony stems near ground level. Then carefully dig around and under each plant. Try to retain as much of the root system as possible.
If desired, large peony clumps can be divided at this time. Using a sharp knife, divide the clump into sections. Each division should have 3 to 5 buds and a good root system.
When replanting, dig a hole large enough to accommodate the entire root system of the peony. Position the plant/division in the hole so the buds are 1 to 2 inches below the soil surface. Fill the hole with soil and water thoroughly.
