Protection from afternoon sun and from harsh winds will help to prolong the lives of the flowers. Peonies will perform best in well-drained, evenly moist, rich soil with a pH near neutral and they are drought-tolerant once established. When planting a Garden Peony, the depth is particularly important. To ensure flowering, the eyes must be planted 1.5 to 2 inches below ground level. An annual topping of compost is recommended each Fall.
