Basically, a tree surgeon looks after trees to improve their life and help them live longer.
You can become a tree surgeon by following various routes; working towards the role, college course or apprenticeship, or via university. A couple of examples of the courses offered at college are Level 2 Certificate in Forestry and Arboriculture or Level 3 Diploma in Work-based Trees and Timber. Maths, English Language and Science skills are also important school qualifications to have; English for communicating well, Maths for measuring and working out prices, and Science for knowing about photosynthesis as well as other related issues.
You can expect to work a full week with some unusual hours, and in some cases the hours vary due to the seasons. You will need to be both mentally and physically fit and have good communication and teamwork skills.
