Peonies produce blooms in a variety of colors and often live up to 100 years. They require at least six hours of full sun per day. Two types of peonies that grace landscapes across the United States are tree peonies and herbaceous peonies. Tree peonies produce permanent growth and do not require pruning. Herbaceous peonies benefit from pruning, and continue to produce beautiful flowers as a result.
Use garden shears to remove dead or dying branches from the peonies each fall.
Cut the stems down within 3 inches of the soil's surface. Discard stems away from the peony's soil to prevent disease transfer.
Gently remove faded, dying or wilted peony blooms with your hands during the growing season. Removing these flowers promotes growth for continuous blooms.
Use the "disbudding" technique when pruning peony flower buds. Prune the side buds with garden shears, while leaving the top (or terminal) buds alone. Disbudding helps peonies produce larger flowers than only pruning peony branches and blooms.
Insert garden stakes in the ground after pruning. Garden stakes act as a support for peony flowers as they mature.
