Pruning Limelight Hydrangeas: Timing and Technique

When to Prune 'Limelight' Hydrangea

It's not too late to prune your 'Limelight' hydrangeas, but you should act soon. This popular panicle hydrangea blooms in late summer on flower buds that form in late spring. Pruning in early spring keeps the shrub compact and vigorous without sacrificing the coming season's flowers.

How to Prune for Best Results

1. Remove any dead, damaged, or crossing branches first.
2. Cut back the previous year's growth by about one-third to one-half to encourage strong new stems.
3. Shape the plant to maintain an open, airy habit that promotes good air circulation.

Even a hard pruning won't harm 'Limelight'—it responds with robust regrowth and plentiful blooms. Just be sure to finish before new growth elongates significantly in late spring.
