CARE WITH PURPOSE
Caring for lawson cypress
Help it thrive
Choose a cultivar suited to the available space. Provide moisture without stagnant, waterlogged conditions, and avoid burying the base.
Pruning advice
Keep trimming within green growth. Maintain the natural outline of specimen trees; hard cuts into leafless wood generally stay bare.
When can it be pruned?
April–August

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
Widespread browning can indicate root or foliage problems; diagnose before cutting heavily.
