Katsura tree: how to prune it?

  1. It grows into a fine shape on its own, often multi-stemmed: let it keep its natural form.
  2. Want a single trunk? Then only remove double leaders on a young tree. On a multi-stemmed tree, keep three to five well-spaced stems.
  3. Don’t saw off thick branches: large wounds heal slowly.

How much to cut, and how often?

  • There are 2 pruning periods a year: July–August and November–February. You don’t have to prune in every one.
  • Grows best when left alone. Only remove dead, diseased or awkward branches.

What does it mean for wildlife?

  • Pruning in July–August can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
  • 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: Needs moist soil and won’t tolerate long dry spells: water it for the first few years.
