How to Support Climbing Hydrangeas

Overview

Climbing hydrangea (Hydrangea anomala petiolaris) is a flowering vine that climbs up brick, masonry or wood. The vines climb 20 to 75 feet, holding on with root-like aerial tendrils that do not harm the support. The vines are slow to get started, but once established, they grow quickly and need plenty of room. In the spring and summer, climbing hydrangea produce an abundance of showy flowers and foliage. In the fall, the leaves drop, revealing a beautiful cinnamon-colored peeling bark and stems. When established, these plants create an effect that is hard to match.

Step 1

Grow climbing hydrangea on an established tree. They grow quite well on mature trees, encircling the trunk and branches without harming the tree. The vines are quite heavy and will swamp an immature tree.

Step 2

Grow climbing hydrangea on large wood, brick and masonry walls. The vines grow densely on walls and can cover structures. They will not grow on cement walls.

Step 3

Support climbing hydrangea on sturdy arbors. The heavy vines require a sturdy support that is well anchored.

Step 4

Support climbing hydrangeas on a pole such as a telephone pole or power pole. Hydrangeas will climb straight up, attaching to the wood and covering the pole.

Step 5

Allow climbing hydrangea to grow as a ground cover. The vines will cover the ground if no vertical support is available or can be mounded into a small bush form. Prune to keep the vines contained.
