Question
I have some peonies that I transplanted to their present location some 12 years ago. They have done well there but I would like to divide them and  move some to different location in my yard. What is the best time to do this?
I live in south central Pennsylvania about 45 miles north of Baltimore Md.

Hi, Kelly,
 Peonies are about the hardiest plants in the world.  I've been trying to get rid of some for 5 years and little sprouts STILL come up.  I transplanted them but obviously didn't get all the plant.
 Division of large peony clumps. After digging up the peony, shake gently to remove loose soil from the root system. Divide the clump into sections, making sure each division has at least 3 to 5 eyes (buds-or bud stems) and a good portion of the root system.

Peonies grow best in full sunlight 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. (Peonies planted deeper than 2 inches often fail to bloom satisfactorily.) Fill the hole with soil, firming the soilas you backfill, then water thoroughly. Space plants about 3 to 4feet apart. Apply a 2 to 3 inch layer of mulch in late fall.Straw is an excellent mulch. Mulching will prevent repeated freezing and thawing of the soil that could damage the plants.Remove the mulch in early spring before growth begins.

Transplanted peonies will not bloom well the first spring.They should be back to full flower production by the third or fourth year.
