Judas tree: how to prune it?

  1. Prune as little as possible: large wounds heal poorly.
  2. Leave old branches and the trunk alone: flowers appear there too in spring.
  3. For a multi-stemmed tree, choose three to five well-spaced stems on a young plant and remove the rest.

How much to cut, and how often?

  • One pruning period a year: June–July.
  • Grows best when left alone. Only remove dead, diseased or awkward branches.

What does it mean for wildlife?

  • Pruning in June–July can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
  • Judas tree flowers in April–May, 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

  • Clipping without first checking for nesting birds.
  • 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: Dislikes being moved: choose the right spot from the start.
