No pruning is needed. If something has to go, cut it straight after flowering, in late April or May.

What else to prune in those months? April · May

Buttercup winter hazel (Corylopsis pauciflora): how to prune it?

1. Cut out dead, damaged and crossing branches, back to a healthy side branch.
2. On an older shrub, remove one of the oldest branches at the base now and then to keep it open.
3. Never clip it into shape: that destroys its graceful, natural habit.

How much to cut, and how often?

• One pruning period a year: April–May.
• 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.
• Buttercup winter hazel (Corylopsis pauciflora) flowers in March–April, when it attracts bees.
• If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
• 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.
