Lydian broom (Genista lydia): when to prune it?
Straight after flowering, in June–July.
Lydian broom (Genista lydia): how to prune it?
- Cut the faded shoots back to just above the old wood, where green shoots remain.
- Remove dead or bare branches.
- Keep the pruning light: a third of the new growth is enough.
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.
- Lydian broom (Genista lydia) flowers in May–June, 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: Never cut into old, bare wood: broom will not regrow from it.
