Pruning and Fertilizing Lacecap Hydrangeas for Better Blooms

Pruning and Fertilizing Lacecap Hydrangeas for Better Blooms

A gardener has healthy lacecap hydrangeas but few, small blooms. They ask about fall pruning.

Pruning Timing

Lacecaps (H. macrophylla normalis) bloom on old wood. Pruning in fall or spring removes next year's flower buds.

Correct Approach

• Only remove dead wood in late spring.
• Trim remaining stems to the first strong pair of buds.
• Thin weak stems to improve air flow.

Fertilizing

Apply fertilizer for acid-loving plants (e.g., Holly-tone) in spring. This, plus proper pruning, should increase bloom size and quantity.
