Now is the time to prune tree peonies

Rosie Lerner, Extension Consumer Horticulturist, Dept of Horticulture & Landscape Architecture, Purdue University

Tree peonies are semi-hardy woody shrubs in our area and typically suffer some dieback during the winter. Early spring is an excellent time to assess winter's toll and prune to remove damaged stems. For minor dieback, cut back to just above a healthy bud or branch. Some stems might be best removed low to the ground, particularly following severe winters or if plants are overgrown and crowded.
