Hydrangea Winter Pruning: The Mid-February Rule

Pruning hydrangeas to the ground in fall risks severe winter kill — the unpruned stems buffer the crown from extreme cold.

Why Leave Stems Standing

• Insulation: Old stems protect crown and basal buds.
• Freeze progression: Hard freezes kill top-down; long stems sacrifice tips, save crown.
• Observation: Fall-pruned plants often lose more wood than unpruned after severe winters.

Correct Pruning Window

• Wait until mid-February (late winter).
• Cut to half height — removes winter-killed tips, shapes plant.
• Side prune as desired for form.

Spring Recovery

Hydrangeas regrow rapidly from basal buds in spring. The mid-February timing balances winter protection with early spring growth initiation.

This conservative approach prevents the "Mother Nature over-pruning" that leaves plants shorter than desired.
