Grey willow: how to prune it?

  1. Tolerates hard pruning: you can cut it back low down every few years.
  2. In a hedge or hedgerow, don’t cut the whole shrub back at once: do part of it each time, so there is always some cover.
  3. In between, remove dead and broken branches.

How much to cut, and how often?

  • One pruning period a year: April–May.
  • Can be cut back to just above the ground every few years and will then regrow.
  • Prune in moderation: never remove more than about a third of the shrub at once.

What does it mean for wildlife?

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

  • Clipping without first checking for nesting birds.
  • Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.

Caution: In spring, check first that no birds are nesting in the shrub.
