When and how to prune climbing hydrangea ( Hydrangea petiolaris). A climbing hydrangea flowers on the previous year’s growth. If necessary, you can control its growth. Cut back outward-growing stems to a healthy bud, after flowering in late summer. Severe pruning may result in less flowers the following year.
Hydrangea petiolaris is excellent for clothing a wall. Although it’s self-clinging, a young plant needs support to help it on its way. This vigorous climber can become quite large over time, so give it plenty of room.
Water a young plant thoroughly if conditions are dry.
