Pearlbush: when to prune it?
Straight after flowering, from late May into June. It flowers on the previous year’s wood.
Pearlbush: how to prune it?
- Cut the flowered shoots back to just above a strong young shoot.
- Each year remove one or two of the oldest branches at the base, to make room for young ones.
- Remove thin, weak or crossing branches.
How much to cut, and how often?
- One pruning period a year: May–June.
- Prune in moderation: never remove more than about a third of the shrub at once.
What does it mean for wildlife?
- Pruning in May–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.
- Pearlbush flowers in April–May, 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.
Caution: If you prune in winter or early spring, you cut off the flower buds.
