I have several varieties of Paniculata Hydrangeas (i.e. Vanilla Strawberry) that have grown out of control. When can I prune these back and still have them bloom the following year?

Hydrangea paniculata, sometimes called Hardy Hydrangea, also blooms on new wood. You should prune it back in late winter or early spring. You can cut it back to the ground or, if you want slightly taller plants, cut it back to one to three feet. For more information check
