Cheshire Tree Surgeons have been providing innovative and efficient tree care since 1985. Throughout that time we have been developing a way to manage trees that is the most sympathetic, the most intuitive and understandable way to manage the size or storm prepare your trees. The research and principles comprising Reduction Via Thinning (which is Simulated Wind Pruning, based on how trees are designed to grow and then in maturity, how they are designed to progressively fail from the edges) is delivered in a book by David Lloyd-Jones titled Tree Morphogenesis book 1 Reduction Via Thinning Theory. Cheshire Tree Surgeons clients get a free copy with any tree works, alternatively you can buy the Kindle version or the printed version (see www.TreeMorphogenesis.com ) and claim the costs off the price of any CTS contract.
