Hydrangea Recovery After Severe Pruning

Hydrangea Recovery After Severe Pruning

A hydrangea was chewed to 3-inch nubs by a puppy in 2005. It regrew foliage in 2006 but produced no flowers. The owner asked if it would bloom again.

Bloom Timeline by Type

• Hydrangea arborescens (e.g., 'Annabelle') and H. macrophylla (bigleaf): Bloom on new wood. Will almost certainly flower the next year (2007).
• Panicle hydrangeas (e.g., 'Peegee'): Bloom on old wood. May take 2–3 years to recover flowering wood.

Care During Recovery

• Do not prune further; let all growth remain.
• Fertilize in spring with a balanced, slow-release fertilizer.
• Ensure consistent moisture and mulch.
• For macrophylla, soil pH affects flower color (acidic = blue, alkaline = pink).

Patience is key—the plant is rebuilding its framework.
