Darley Dale heath (Erica × darleyensis): how to prune it?

1. Use shears to clip off the spent flower spikes, just below the old flowers.
2. Cut only into the green, leafy part of the shoots.
3. This keeps the plant compact and makes it grow new shoots that will flower next winter.

How much to cut, and how often?

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

What does it mean for wildlife?

• Pruning in April–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.
• Darley Dale heath (Erica × darleyensis) flowers in December–April, 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.
