Peony roots should be handled delicately because the roots are brittle, and the buds may pop off. The buds are located at the top of the root. The buds should be planted 1-2 inches deep depending upon the settling and packing of the soil as you plant.
The site for planting should have 3/4 to full sun every day. A shady site will stop a peony from blooming.
Select a well-drained site away from overhanging roof eaves.
The hole should be at least 16 inches wide by 16 inches deep. A larger hole is better if your soil is compacted or very rocky. Add soil amendments as needed. Lightly mulch in cold climates. Remove mulch in the spring. Weed grass from around the peony plant.
Water thoroughly after planting. Fertilize lightly.
Space plants 3-4 feet apart in rows or mass landscape plantings.
