CARE WITH PURPOSE
Caring for wych elm
Help it thrive
Prefers fertile, moist but drained soil. Retain healthy trees and seek prompt advice if foliage yellows or wilts suddenly in summer.
Pruning advice
Avoid unnecessary wounds. Suspected Dutch elm disease needs diagnosis and a specific management plan, rather than routine crown trimming.
When can it be pruned?
December–February, after local disease advice

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
Sudden summer wilting can indicate Dutch elm disease; do not move suspect elm wood without advice.
