Peonies are a staple flower in gardens worldwide. They are easy to grow and offer lovely blooms. Plus, most varieties are hardy though zones 3 to 8, so they can handle a large range of weather. However, sometimes a peony plant is either too large for its bounds or it starts getting too much shade from other plants. In these cases transplanting peonies to a more favorable location in your garden is the best idea.
Transplant peonies in the late summer, around September, as the weather starts to cool. If you live in a warmer climate you can transplant them in the early fall.
Choose a new spot in your garden for your peonies. Peonies like full sun and well drained soil in order to produce their best blooms.
Cut off the foliage of the peonies you wish to transplant to about 5 or 6 inches from the base of the plant. Remove all flowers and leaves.
Dig a hole around your mature peonies. Dig far enough from the base of the plant to avoid cutting any of the peonies' roots, about 6 or 7 inches. Dig in a circle around the base of the plant until soil is loose enough that the peonies can be easily lifted.
Remove the peonies from the ground and place them on the tarp.
Dig a hole for the peonies in the new spot. Make sure the hole is deep enough to accommodate the peonies' roots and about twice as wide.
Place the peonies in the hole so the buds are an inch or two below the surface of the soil.
Fill the hole with soil and pat it down firmly. Water the peonies well for several minutes.
Mulch over transplanted peonies in the fall after the ground freezes.
