Spirea Pruning Depends on Bloom Time

Spring vs. Summer Bloomers

Spring-blooming (e.g., 'Bridal Wreath'): Prune after flowering (late April).
Summer-blooming (Japanese, bumalda types): Prune early spring—they flower on new growth.

Identify your spirea type before cutting. Severe pruning at the wrong time removes the current season's flower buds.
