Irish heath (Erica erigena): when to prune it?
After flowering, in May.
What else to prune in those months? May
Irish heath (Erica erigena): how to prune it?
- Lightly trim the faded tips with secateurs or shears.
- Do not cut into old, bare wood: the plant regrows from it poorly.
- A light trim every year keeps the shrub dense and stops it opening up in the middle.
How much to cut, and how often?
- One pruning period a year: May.
- Prune in moderation: never remove more than about a third of the shrub at once.
What does it mean for wildlife?
- Pruning in May can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
- Irish heath (Erica erigena) flowers in February–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: Do not prune in autumn or winter: you would remove the flower buds for spring.
