Dig a hole large enough for the entire root system. Place thepeony plant in the hole so the eyes are 1 to 2 inches below thesoil surface. 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 repeatedfreezing 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 orfourth year. Iowa State University , Ames, Iowa.
