Prune hydrangeas based on their type. For bigleaf and oakleaf varieties, prune right after they bloom in summer as they flower on old wood. Panicle and smooth hydrangeas should be pruned in late winter or early spring as they bloom on new wood. This timing ensures they have enough time to establish new growth for blooms. Avoid pruning in late fall or mid-winter to prevent damaging new budding flowers.
