However the plants must be potted in early fall and appropriately winterized. Otherwise they will have the same problem as bare root plants. We have tried some potted Japanese tree peonies in the spring. They died in several weeks after spring planting. Loamy soil with good drainage.
Top soil mixed with compost is the best.
The ideal pH range is 6.5 to 7.5. The Chinese tree peony can be planted under full sun or part sun. It requires at least 4 to 5 hours of sun light daily. In areas where it is very hot in April, during the blooming season, the heat causes the flowers to wilt and drop fast. In this case, it is better to plant it in a semi-shady area.
