Sweet osmanthus (Osmanthus fragrans): how to prune it?

1. Cut frosted or brown stems back to healthy wood.
2. Lightly shorten stray shoots to keep the shrub dense and shapely.
3. Never prune hard: it grows slowly and recovers slowly.

How much to cut, and how often?

• One pruning period a year: April.
• Prune in moderation: never remove more than about a third of the shrub at once.

What does it mean for wildlife?

• Pruning in April 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.
• Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
