When is the best time to plant peonies?
Peonies are available as potted and bare-root plants. Potted peonies are often available at garden centers and can be planted anytime during the growing season. Bare-root peonies are typically purchased from mail-order nurseries. Bare-root peonies are planted in late summer/early fall (September in Iowa). When planting bare-root peonies, position the “eyes” (buds) 1 to 2 inches below the soil surface.
