|All hydrangeas can be deadheaded. How much you remove when you deadhead depends upon the type of hydrangea you are growing. Some types of hydrangeas produce flowers on new growth which develops on old wood. Other types bloom on both old and new growth. Since you're in a cold winter region I suspect you are growing a hardy hydrangea such as Endless Summer. If so, this plant blooms on both old and new growth. The first blooms appear on the previous years wood, and the later season blooms appear on the new growth of the current season. You can prune as little or as much as necessary to help keep the plant within bounds. Pruning will not affect next year's flowers. Hope this information is helpful.
