CARE WITH PURPOSE

Caring for hazel

Help it thrive

Grows well in fertile, moist but drained soil. Allow a broad base and retain varied stem ages for habitat and nut production.

Pruning advice

Thin selected older stems at the base. Traditional coppicing is a planned rotation; leave some mature growth if nuts and wildlife are priorities.

When can it be pruned?

Highlighted months are an indicative window for the work described, not a reason to prune every year. An unshaded month is not an absolute ban.

Timing must suit the tree's health, weather, wildlife and legal protection. Avoid severe frost, drought and vulnerable new leaf growth. Mature trees, major branches and suspected defects need professional assessment.
