Late cotoneaster (Cotoneaster lacteus): how to prune it?

1. Free-standing shrub: in March, cut out only dead, damaged or overlong branches just above a side branch, keeping the natural arching shape.
2. Hedge: in August, trim back the long new shoots and spare the clusters of young berries where you can.
3. Renovate an overgrown shrub in March by sawing a few old branches out at the base, spread over two or three years.
4. Prune in dry weather and disinfect your secateurs to reduce the risk of fireblight.

How much to cut, and how often?

• There are 2 pruning periods a year: March and August. You don’t have to prune in every one.
• Prune in moderation: never remove more than about a third of the shrub at once.

What does it mean for wildlife?

• Pruning in March and August can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
• Late cotoneaster (Cotoneaster lacteus) flowers in June–July, when it attracts bees.
• 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.
