CARE WITH PURPOSE
Caring for common juniper
Help it thrive
Give full sun and sharply drained soil. Avoid crowding and damp, stagnant conditions; mature plants need little feeding.
Pruning advice
Trim only small green tips if necessary. Avoid cutting back into bare old wood, which may remain permanently brown.
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.
Tree health: what to watch for
Dieback may indicate disease or poor drainage; check the cause before trimming affected plants.
