Three-Year-Old Hydrangeas Not Blooming: Pruning Timing, Sun, and Soil Fixes

Hydrangea Bloom Failure in Zone 5

• Pruning: Only in fall after bloom. Spring pruning removes flower buds.
• Sun: Morning sun, afternoon shade if summers are hot.
• Soil: Moist, well-drained, acidic (Miracid).
• Fertilizer: Low N, high P/K.

Correct these, and blooms will return.
