How to prune hydrangea 'endless summer'

Late winter to early spring once green buds are visible on stems; after individual flowers fade in summer. Wait until green growth is clearly visible on stems, then remove only dead wood and cut brown, crunchy stems back to the nearest live bud. You can remove up to one-third of the oldest stems to rejuvenate. Deadhead spent blooms individually through summer — never cut back hard after August.

Light annual pruning in spring; individual deadheading as blooms fade through summer. Endless Summer hydrangea (H. macrophylla) blooms on both old and new wood, making timing critical. Prune only lightly in late winter or early spring — wait to see green buds before cutting. Remove dead wood and cut stems with brown, crispy buds back to the first living node. Never prune after August, as fall buds set next season's early blooms.
