Answer: The traditional time to dig and divide (and replant) peonies is in the fall. However, peony "eyes" may also be planted in the early spring, and container-grown peonies may be planted at any time during the growing season or in fact, at any time the soil can be dug. Mid summer would be the least desirable time to plant, however, due to the potential for heat and drought stress on the newly developing root system. I hope this answers your question.
