Soil and Preparation:
Peonies prefer well-draining, humus-rich moist soil. Amend heavy or very sandy soil with compost. Additionally, 1 cup of bonemeal can be used to amend the soil prior to planting. Choose a location in full sun, but one that provides ample growing room along with protection from strong winds.
Dig a a hole large enough to accommodate the roots and set the root so the eyes face upward. Fill in the hole, making sure to keep the peony's eyes/buds not deeper than 2" below the soil line. Water thoroughly to settle the soil around the roots.
Fertilization During Growing:
They do not require fertilization other than a yearly addition of compost unless a soil test shows a deficiency in nutrients.
