Pruning japanese spirea — FAQ
When should I prune japanese spirea?
Early spring before new growth, just as buds begin to swell. Cut all stems back to 6–12 inches from the ground using sharp secateurs or loppers in early spring. After the first summer flowering flush, shear off faded flower heads to just above a set of leaves to encourage a second bloom later in summer.
How often does japanese spirea need pruning?
Annually in early spring; deadhead after flowering. Japanese Spirea (Spiraea japonica) flowers on new wood and benefits from hard pruning each spring to keep it compact and flowering vigorously. Cut the entire shrub back to 6–12 inches in early spring before growth starts. Deadhead after the first flush for a potential second bloom. Without pruning, plants become woody and flower poorly.
