Winter Injury on Rhododendron

B. Rosie Lerner, Extension Consumer Horticulture Specialist

Even during mild winters, evergreens can show symptoms of winter dessication. Broadleaved evergreens such as rhododendrons have a greater surface area through which to lose water compared to deciduous plants making them particularly susceptible to injury. Broad-leaved evergreens that have suffered from winter dessication typically have beige to brown leaf edges that are curled. Severe drying will be obvious as dead twigs and buds as spring growth fully develops. Some twigs will leaf out in spring only to die back later in summer as heat stress sets in.
