Gum rockrose (Cistus ladanifer): how to prune it?

1. Trim the faded tips and seed capsules back to just above the foliage.
2. Never cut into old, bare wood: it will not reshoot from there.
3. Dead branches can be removed at any time.
4. An old, bare shrub cannot be renovated: replace it with a young plant or a cutting.

How much to cut, and how often?

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

What does it mean for wildlife?

• Pruning in July–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.
• Gum rockrose (Cistus ladanifer) flowers in June–July, 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.
