Tree pruning – In order to maximise the benefits and minimise the hazards associated with trees in the city, well-developed urban forest and well-planned tree management have become more important. Urban trees should be continuously cared for throughout their life span through measures such as proper irrigation, mulching, fertilisation and appropriate mitigation measures, such as pruning and provision of supporting system. Amongst the various mitigation measures, tree pruning is essential in every tree maintenance and risk management scheme. Tree pruning is a practice of removing specific portions of a tree to achieve long-term maintenance of good tree health, structural integrity, aesthetics and safety of public and properties. Appropriate pruning parameters (e.g. pruning type, pruning time and pruning extent) should be carefully determined according to different pruning objectives, tree species and tree conditions, etc. Given its significance in ensuring good health and structure of trees, thereby, protecting public safety, pruning work should follow a set of good working procedures, standards, and safety guidance, and be performed by registered personnel with adequate knowledge and skills in tree pruning and work supervision.
