Hydrangea All Leaves, No Flowers: Fertilizer, Soil, and Pruning

Your hydrangea grows lush foliage but no blooms. Three common causes:

1. Fertilizer Imbalance

• Too much nitrogen (lawn fertilizer runoff?) → leaves, no flowers.
• Feed every 2 weeks with bloom-boosting fertilizer (high phosphorus, e.g., 10-30-10).

2. Soil pH

Hydrangeas need acidic, lime-free soil. Use ericaceous compost and fertilizer for azaleas/rhododendrons.

3. Pruning Timing

• Cut stems back to half after flowering season.
• Don't prune in spring—you'll remove flower buds.

Other Needs

• Frequent watering (large leaves transpire fast).
• Bright light, no hot midday sun.
• Summer outdoors, winter in cool room (sparingly watered).

Adjust these, and next spring/summer should bring flowers.
