Knowing when to prune spirea helps maintain its shape, encourage healthy growth, and support beautiful flowering. The best time depends on the variety you grow. Spring-flowering spirea should generally be pruned after its flowers fade, while summer-flowering varieties are best pruned in late winter or early spring before new growth begins. Avoid heavy pruning at the wrong time, as it may remove flower buds and reduce blooming. Remove dead, damaged, or crossing branches whenever necessary. With the right timing and proper care, spirea can remain attractive throughout the growing season. Gardyna shares practical gardening tips to help you care for your plants.
