Restoring Blooms to Non-Flowering Hydrangeas

Pruning Timing Is Critical

Hydrangea macrophylla blooms on old wood. Fall or spring pruning removes flower buds. Stop pruning after July.

Other Bloom Barriers

• Insufficient sun: Need 4–6 hours (morning ideal). Deep shade prevents flowering.
• Soil depletion: Amend annually with compost/manure.
• Nitrogen excess: Promotes leaves over flowers. Use balanced or bloom-boost fertilizer.

Action Plan

1. Cease all pruning except deadwood removal.
2. Top-dress with 2–3" compost.
3. Apply liquid fish/seaweed fertilizer monthly spring–early summer.
4. Ensure adequate light (thin overhead branches if needed).

Patience: May take a season to rebuild bud set.
