Peonies are hardy, long-lived perennials grown commercially and privately for their large, showy flowers. Peonies are typically considered relatively easy to grow; however, there are a number of pathogens and pests that affect peony health. Many of the disease issues on peonies can be mitigated with the implementation of general cultural management strategies while other diseases require more specific approaches. The purpose of this publication is to provide a basic introduction to plant diseases and plant disease management and also to familiarize growers and homeowners with the most common diseases of peony in the United States, including how to identify and manage them.
