Why Althea (Rose of Sharon) Branches Droop

Heavy Blooms Cause Natural Arching

Mature Althea (Hibiscus syriacus) often droops under the weight of prolific summer flowers. This is a normal growth habit, not a disease or pest issue. The plant in the photo shows healthy leaves and no pest signs.

Management

• Shape shrubs annually to build stronger framework.
• Prune after flowering to reduce future limb weight.
• Accept some arching as characteristic of the species.

Similar drooping occurs in hydrangeas and snowball bushes during heavy bloom years.
