What Happens If You Don’t Cut Back Hydrangeas?

What happens if you don't cut back hydrangeas? Hydrangeas that bloom on old wood do not need pruning and are better off for it. If you leave them alone, they'll bloom more profusely the next season. Just remember new growth may come, but that new growth will be without blooms next season.

Likewise, When should you not cut back hydrangeas?

Trimming should be done immediately after flowering stops in summer, but no later than August 1. Do not prune in fall, winter, or spring or you could be cutting off new buds. Tip-pruning the branches as leaves emerge in spring can encourage multiple, smaller flower heads rather than fewer larger flower heads.

Similarly, Should hydrangeas be cut back for winter? Hydrangeas bloom either on old wood or new wood, depending on the hydrangea type. New-wood blooming hydrangeas should be cut back in late winter before new growth begins, while old-wood bloomers require pruning right after flowers fade in late summer.
