When pruning flowering shrubs that bloom on last year’s wood, when should pruning occur to preserve next year’s buds?

• A. Prune in winter after frost.
• B. Prune just after flowering to preserve next year’s flower buds.
• C. Prune in early spring before buds open.
• D. Prune during summer heat.

Answer: (C)

When a shrub flowers on last year's wood, the buds that will bloom next year are already set on that old wood. Pruning right after flowering finishes lets you remove spent blooms and shape the plant without knocking off those next-year flower buds. This timing supports new growth that will carry future blooms while keeping the old wood that bears the next year’s flowers intact. Pruning in winter after frost can remove wood that already holds next year’s buds, weakening next season’s display. Pruning before buds open in early spring risks cutting into developing flower buds, and pruning in hot summer weather adds stress without benefiting bloom production.
