Should I Cut Back Peonies In The Fall?
Cutting back herbaceous peonies in the fall makes sense once the foliage has yellowed and died back naturally, especially if you want to reduce disease pressure. Tree peonies and Itoh peonies need different treatment, so identifying your peony type is the first step. The choice mainly depends on your plant variety, local climate, and whether the foliage showed signs of disease during the growing season.
