Manna ash: when to prune it?

Dead, diseased and broken branches can be removed at any time of year. If pruning is needed, do it during winter dormancy (November–March).

Prune while dormant, from November to March, but not in freezing weather.

Manna ash: how to prune it?

  1. Little pruning needed. Formative pruning of a young tree in winter.
  2. Remove crossing and dead branches; cut large branches in three stages, just outside the branch collar.

How much to cut, and how often?

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

What does it mean for wildlife?

  • Pruning in March 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: Don’t prune a healthy tree in spring or summer: that is when it flowers and birds are nesting.
