When pruning deciduous shrubs that bloom irregularly, what is a quick guideline to avoid cutting buds for next year's flowers?

• A. In late winter
• B. After flowering
• C. During active growth
• D. At the onset of dormancy

Answer: (B)

Pruning after flowering is the best approach because many deciduous shrubs form the buds for next year’s flowers on the wood that grew this season. If you cut back or shape a shrub while it’s still blooming, you may remove those future flower buds and reduce next year’s display. Waiting until after it has finished blooming lets you tidy up and shape the plant without risking losing the buds that will carry next year’s flowers. This is especially helpful for irregular bloomers, where predicting bloom timing isn’t reliable. Pruning during active growth or before flowering can trim away buds that would have opened next year, and pruning in late winter or at the onset of dormancy can also remove buds formed for next season. So the simple rule is to prune after flowering.
