Diseases of Paeona sp. (Peony)

Paeona sp. (Peony) get botrytis and anthracnose. Both diseases cause buds, flowers, leaves, and stems to die. These two diseases often cause similar damage. Culturing is usually necessary for proper identification. Grow in full sun and good air circulation. Fungicides and sanitation are helpful.
