Paperbark maple: when to prune it?
As little as possible. If you must, do it in November or December, when the tree is dormant.
Paperbark maple: how to prune it?
- Remove only dead, damaged or crossing branches.
- Cut just outside the swollen collar at the base of the branch, without leaving a stub.
- To show more of the trunk, gradually remove the lowest branches over a few years.
- Use sharp, clean tools so the wounds close quickly.
How much to cut, and how often?
- One pruning period a year: November–December.
- Never remove more than about a quarter of the crown at once. Better a little every year.
What does it mean for wildlife?
- The pruning months fall outside the nesting season (15 March–15 August), so you won’t disturb nesting birds.
- Prunings can go on a dead hedge or brash pile in a corner of the garden: shelter for hedgehogs, wrens and insects.
Common mistakes
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Never prune in late winter or spring: the tree then bleeds heavily from the pruning cuts.
