The Care of Peonies in Minnesota


Peonies are herbaceous perennials native to Asia, Europe and North America. They typically grow up to 3 feet in height and 3 feet in diameter. Peonies are hardy in USDA hardiness zones 4 through 9, making them ideal for use in lawns and gardens throughout Minnesota. They produce flowers during late spring and early summer that can be pink, red or white in color. Peonies require regular care and maintenance to survive in Minnesota, but they'll thrive if the correct growing conditions are provided.

Step 1

Plant peonies in Minnesota during late spring after all danger of frost has passed. Choose a planting site that receives four to six hours of direct sunlight each day. Space peonies at least 3 feet apart.

Step 2

Spread a 2-inch layer of mulch over the soil surrounding peonies to insulate the soil, improve moisture retention and suppress weeds. Replenish the mulch as often as necessary to keep the layer 2 inches deep.

Step 3

Water peonies in Minnesota once every five days during the first two months of growth. Reduce the frequency of watering to once per week thereafter, keeping the soil consistently moist.

Step 4

Feed peonies once every three months using a balanced 10-10-10 NPK fertilizer. Water both before and after applying to release the nutrients into the soil and prevent root burn. Apply following the manufacturer's directions found on the product.

Step 5

Prune peonies during late winter, just before new growth begins in the spring. Use pruning shears to remove branches damaged by the cold Minnesota winter to improve the aesthetic appeal and health of the plant.
