Prune while dormant, from November to March, but not in freezing weather.

Hop-hornbeam: how to prune it?
- Little pruning needed. Formative pruning of young trees in winter.
- Remove crossing and low-hanging branches; cut large branches in three stages, just outside the branch collar.
How much to cut, and how often?
- One pruning period a year: November–February.
- Grows best when left alone. Only remove dead, diseased or awkward branches.
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
- Pruning too much: it grows best when left alone.
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Don’t prune during the nesting season, and leave large trees to a tree surgeon.
