When to Prune Hydrangeas: Complete Guide by Variety

Hydrangea pruning timing varies by type. All benefit from spent bloom and dead stem removal, but incorrect timing sacrifices flowers.

By Variety Pruning Schedule

Florist Hydrangea (H. macrophylla / Mophead / Bigleaf)

• Blue flowers in acidic soil; pink in alkaline; some white
• Dark glossy leaves with serrated edges
• Prune after flowers fade
• Remove old/dead branches timely but retain some for new growth support
• Never prune spring or late fall—loses buds/blooms

Climbing Hydrangea (Vine form)

• Minimal summer pruning only
• Wait until established with vigorous growth

Peegee Hydrangea

• Large snowball clusters: white → pink maturity
• Blooms mid-late summer
• Prune late winter to early spring—promotes flower buds
• Clear dead flowers for shape

Oakleaf Hydrangea (H. quercifolia)

• Distinctive oak-shaped leaves
• Prune late winter to early spring
• Remove dead wood during this window

Regular, variety-appropriate pruning ensures healthy growth and abundant blooms.
