Hydrangea

Question

Our Hydrangea bushes have grown to their size last year. We pruned them in the spring, and two of the bushes have their blooms inside of the bush instead of outside. The third was pruned at the same time, but its blooms are all outside of the bush. The bushes are so big they are overtaking our windows. When should we trim them down (we live in southern New Jersey) and how far down should we trim them?
