When to Prune Hydrangeas: Winter vs. Summer Timing

Critical Pruning Window

For Hydrangea macrophylla (bigleaf):

• Prune AFTER flowering (mid-July to August).
• NEVER prune in winter or early spring—removes next year's buds.

Current Situation

If unpruned all winter, leave alone. Prune only dead tips. Shape in July after bloom.

Other Types

• Panicle (H. paniculata) / Smooth (H. arborescens): Bloom on new wood—prune late winter.
• Oakleaf (H. quercifolia): Bloom on old wood—prune after flowering.

Rule: Know your hydrangea type before cutting.
