Winter hazel: when to prune it?
After flowering (April–May).
Winter hazel: how to prune it?
- Little needed: only remove dead or awkward branches, to keep its graceful shape.
- If an old shrub becomes too dense, cut one or two of the oldest branches off at the base after flowering.
How much to cut, and how often?
- One pruning period a year: April–May.
- Grows best when left alone. Only remove dead, diseased or awkward branches.
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.
- 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: Late frost can damage the flowers: plant it out of the morning sun.
