Kentucky coffeetree: when to prune it?

As little as possible. If needed: in January–February, on a frost-free day, while the tree is dormant.

What else to prune in those months? January · February

Kentucky coffeetree: how to prune it?

  1. Young trees: choose one central leader and remove competing tops.
  2. Take out dead, damaged and crossing branches.
  3. Do not cut back the top: the tree has few branches and recovers slowly from hard pruning.
  4. Do not leave stubs; cut just outside the branch collar.

How much to cut, and how often?

  • One pruning period a year: January–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.
  • 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: Do not cut the tree back: it branches sparingly by nature and hard pruning ruins its rugged shape. Kentucky coffeetree is poisonous: wear gloves and keep clippings away from children, pets and livestock.
