The Q&A Archives: Peonies turn brown and wilt

Question: My peonies grew to about a foot tall and then the leaves turned brown and the plant wilted. Why?

Answer: Peonies suffer from several blight, rot, and wilt diseases, often in combination. Most of these diseases are soil-borne and are often aggravated by drainage, watering, and cultural practices. Young plants can suffer from these diseases as well as from planting too deeply, insufficient watering, air pockets left in the soil after planting, or attack from rodents.
