Chinese elm: how to prune it?

  1. Tolerates pruning well. Train a young tree on a single leader or into an attractive multi-stemmed shape, and remove crossing branches.
  2. As a bonsai, cut new shoots back to 1–2 leaves once they have 4–6.
  3. Cut diseased branches well back into healthy wood and disinfect your tools.

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 saw a garden tree in spring or summer: fresh wounds attract the elm bark beetle, which spreads Dutch elm disease.
