Downy oak: how to prune it?
- Young tree: choose one central leader if you want a tall tree, or let it grow multi-stemmed for a natural shape.
- Remove dead, broken and crossing branches just outside the branch collar, without leaving a stub.
- Raise the crown gradually, never more than a quarter of the crown at once.
- Leave dead wood in old trees wherever possible: it is valuable for insects and birds, unless it is a danger.
How much to cut, and how often?
- There are 2 pruning periods a year: January–February and August. You don’t have to prune in every one.
- Never remove more than about a quarter of the crown at once. Better a little every year.
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.
- 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.
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Large pruning wounds heal slowly on oaks. Prune young and lightly rather than sawing off thick branches later.
