Diagnosing Tree Disorders

Diagnosing Tree Disorders provides a practical guide to recognising and interpreting the symptoms and causes of poor tree health. Rather than relying on assumptions, the article promotes a systematic approach that considers species characteristics, site conditions, environmental stresses, pests, diseases, soil properties, mechanical damage, and human activities. It emphasises that many disorders produce similar symptoms, making careful observation and evidence-based diagnosis essential. By combining Visual Tree Assessment with knowledge of tree biology and pathology, arborists can identify underlying problems, recommend appropriate management, and avoid unnecessary treatments or removals. The article is an invaluable resource for consulting arborists, land managers, and horticultural professionals.
