Japanese hydrangea vine: when to prune it?

What else to prune in those months? August
Japanese hydrangea vine: how to prune it?
- Cut shoots growing away from the wall back to two or three buds above the permanent framework.
- Keep windows, gutters and roof tiles clear by removing the tips that reach them.
- Remove dead and damaged branches.
- You can leave the faded flower heads; they still look good in autumn.
How much to cut, and how often?
- One pruning period a year: August.
What does it mean for wildlife?
- Pruning in 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.
- Japanese hydrangea vine flowers in July, when it attracts bees.
- 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: it flowers on short side shoots, and a hard prune costs a few years of flowering.
