Panicle Hydrangeas

Panicle hydrangeas should also be pruned in the late winter or early spring before new growth appears.

Oakleaf Hydrangeas

Endless Summer Hydrangeas

Endless Summer hydrangeas bloom on both old and new wood, which means they can be pruned at any time.

The Best Time to Prune Your Hydrangeas
