When do I prune my hydrangeas?
When to prune depends on the type of hydrangeas you have. Pink and blue hydrangeas (Hydrangea macrophylla) and oakleaf hydrangea (Hydrangea quercifolia) bloom on last year’s wood. They should only be pruned just after flowering. Pruning them in late summer, fall or in spring before they bloom will remove the flower buds for next year’s blooms. PeeGee, Annabelle, and tardiva hydrangeas (Hydrangea paniculata and H. arborescens) bloom on the current season’s growth and can be pruned in fall, winter or early spring.
