Q: My husband wants to prune our spirea. But he doesn’t believe me when I insist it blooms twice! Our landscaper used to severely prune it this time of year.

A: Scheduling spirea pruning depends on which kind you have. Spring-blooming spirea shrubs, like ‘Bridal Wreath’, should be pruned after they flower. Late April is a good time. Summer-blooming spirea, such as the Japanese and bumalda types, can be pruned in early spring because they will make flowers on the vigorous new growth that results from spring pruning.
