Pruning Oakleaf Hydrangea: Timing Matters

Oakleaf hydrangea (Hydrangea quercifolia) blooms on old wood. Prune immediately after flowering (July), not in winter.

Why Winter Pruning Is Wrong

• Flower buds for next year form in late summer/fall.
• Winter pruning removes them → no blooms next season.

Correct Approach

• Post-bloom (July): Remove spent flowers, shape lightly, remove dead wood.
• Winter: Do nothing. Exfoliating bark provides winter interest.
• Early spring: Only remove winter-killed tips.

Size Control

If too tall, remove 1/3 of oldest stems to ground each year after bloom. This rejuvenates without sacrificing flowers.

Your oakleaf's big blooms are its glory—prune at the right time to keep them coming.
