I guess this could be considered a "how to prune hydrangeas" question... can a Limelight Hydrangea be snipped back to a new set of buds further down on the stem, similar to the way you would do a typical fuchsia or a coleus plant? our limelight hydrangea doesn't branch very much and its not really all that full. i'd like to cut back the tips of the new growth, which is now anywhere from 4-8 inches long, back to the first set of buds to encourage branching and to keep it bushier. does that work on hydrangeas? or is it a mistake?
