American basswood: how to prune it?
- In the first years train a straight trunk with a single leader and remove competing leaders.
- Take out dead, crossing and damaged branches; cut just outside the branch collar, leaving no stubs.
- Remove low branches gradually if you want a taller clear trunk.
- Suckers and water shoots at the base can be cut away at any time of year.
How much to cut, and how often?
- One pruning period a year: December–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.
- American basswood flowers in June–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
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Have major pruning of a mature tree done by a qualified arborist, and never prune during flowering in June–July.
