Dorset heath (Erica ciliaris): when to prune it?
In spring, in March–April, before new growth starts.
Dorset heath (Erica ciliaris): how to prune it?
- Lightly shear off last year’s faded flower stems with shears.
- Do not cut into old, bare wood: heathers regrow from it poorly.
- A light trim every year keeps the plants compact and stops them going bare in the middle.
How much to cut, and how often?
- One pruning period a year: March–April.
- Prune in moderation: never remove more than about a third of the shrub at once.
What does it mean for wildlife?
- Pruning in March–April can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
- Dorset heath (Erica ciliaris) flowers in July–October, 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.
Caution: Do not prune in autumn: the faded stems protect the plant in winter.
