Field elm: how to prune it?
- Prune or coppice in winter, never in spring or summer: fresh wounds attract the elm bark beetle.
- Trim a hedge into shape in winter; coppice is cut back to the ground every few years and regrows well.
- Remove diseased branches from the site and disinfect your tools.
How much to cut, and how often?
- One pruning period a year: November–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.
- As a native plant, it feeds more insects than a non-native species.
- 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: Mow or cut root suckers in lawns or borders regularly.
