Evergreen climbing hydrangea: when to prune it?
Hardly needed. Trim lightly after flowering, in August, and remove frosted shoots in May.
Evergreen climbing hydrangea: how to prune it?
- After flowering, shorten long, hanging shoots to the desired shape.
- In May, when new growth starts, cut dead or frosted stems back to healthy wood.
- Remove dead and thin stems from the centre.
- Keep it away from gutters and windows.
How much to cut, and how often?
- There are 2 pruning periods a year: May and August. You don’t have to prune in every one.
What does it mean for wildlife?
- Pruning in May and August can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
- Evergreen climbing hydrangea flowers in July–August, when it attracts bees.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
- Prunings can go on a dead hedge or brash pile in a corner of the garden: shelter for hedgehogs, wrens and insects.
Common mistakes
- Clipping without first checking for nesting birds.
Caution: Do not prune hard in winter or early spring: it flowers on older wood, so you would lose flowers.
