What else to prune in those months? June

Paleleaf barberry (Berberis candidula): how to prune it?

1. Cut shoots that stick out back inside the cushion, just above a leaf.
2. Remove dead or damaged twigs back to healthy wood.
3. Rejuvenate an old, bare shrub by removing a few of the oldest stems at the base.

How much to cut, and how often?

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

What does it mean for wildlife?

• Pruning in June can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
• Paleleaf barberry (Berberis candidula) flowers in May, 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.
