Non-Flowering Hydrangea: Pruning Timing and Shade Issues

Primary Cause: Wrong Pruning Time

Pruning to 3 inches from ground in fall/winter removes flower buds on old-wood hydrangeas (macrophylla, serrata). Prune only after flowering in summer.

Secondary Cause: Excessive Shade

North-side planting may be too shady for bud formation. Hydrangeas need morning sun / afternoon shade.

Remedial Steps

• Stop hard pruning. Remove only dead wood in spring.
• Apply low-nitrogen fertilizer in fall.
• Protect from harsh winter (burlap screen).
• If shade is heavy, consider transplanting to brighter spot.
