Why Deadhead Lacecap Hydrangea? Energy for Blooms, Not Seeds

Deadheading lacecap hydrangea (Hydrangea macrophylla normalis) redirects energy from seed production to next year's flower buds.

The Logic

• Seed production is metabolically expensive—like pregnancy.
• Every ounce spent on seeds is an ounce not spent on flower buds forming in late summer.
• You don't want the seeds (hybrids don't come true; 20-year wait for bloom).

Correct Method

• Cut spent blooms off just below the flower head when they fade (late summer).
• Do NOT prune to "second set of buds" in fall/winter—that removes next year's flowers.
• General pruning: Only remove dead wood in spring. Shape after bloom if needed.

Bigleaf Hydrangea Bud Timing

Flower buds set at branch tips in late summer/early fall. Pruning after that = no flowers.

Deadhead for more blooms. Leave the structural pruning for post-bloom summer.
