Good Morning,
Before pruning your hydrangea, you must know which species it is and flowering habit it has. Bigleaf (both mophead and lacecap), oakleaf, and mountain cultivars bloom on “old wood,” or stems formed the previous year. Usually these species require very little pruning. When necessary, these cultivars should be pruned shortly after flowering to avoid removing developing buds. The next year’s flower buds begin forming in August.
