Pruning Rose of Sharon: Timing for Shape Control

When to Prune Rose of Sharon (Hibiscus syriacus)

Ohio homeowner transplanted Rose of Sharon 1.5 years ago. It died back but returned vigorously with summer flowers. Wants to trim for width over height.

Advice

Prune in winter or early spring while dormant. "When the pruners are sharp" is the old gardener's rule. Enjoy flowers until frost. Hibiscus syriacus naturally branches well; pruning mainly for shape/size control.
