American hornbeam: when to prune it?
It needs little pruning; if needed, in winter, in January–February, when the tree is bare.
What else to prune in those months? February
American hornbeam: how to prune it?
- Remove dead, damaged and crossing branches.
- Cut small branches just outside the branch collar, never flush with the trunk.
- On a young tree, remove competing leaders and keep a single main leader.
- Never remove more than a fifth of the crown in one year.
How much to cut, and how often?
- One pruning period a year: February.
- 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.
