Bog rosemary: how to prune it?

  1. Lightly trim spent flower clusters and overlong shoots.
  2. Remove dead or brown shoots in spring.
  3. Never cut hard into old wood.

How much to cut, and how often?

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

What does it mean for wildlife?

  • Pruning in June–July can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
  • As a native plant, it feeds more insects than a non-native species.
  • 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.

Caution: Wear gloves and clear up the clippings: all parts are poisonous.
