Rockrose (Cistus × hybridus): how to prune it?

1. After flowering, shorten this year’s shoots by about a third to keep the shrub compact.
2. Always cut into green, leafy wood and never into old, bare branches.
3. In April, cut back shoots browned by frost to just above healthy green leaves.
4. An old, bare shrub cannot be rejuvenated by hard pruning: replace it with a young plant grown from a cutting instead.

How much to cut, and how often?

• There are 2 pruning periods a year: April 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 April 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.
• Rockrose (Cistus × hybridus) flowers in May–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.
