• <br /> COSTS ESTIMATES AND DESCRIPTIONS OF REMEDIES: <br /> It is impossible to provide cost calculations per tree without first knowing <br /> the scope and frequency of treatments desired. When several different kinds <br /> of treatments are provided for the same tree, the cost goes down. As to the <br /> frequency of treatments, we recommend a minimum of every three years. If <br /> you decide to treat once every five years, naturally the cost will also be <br /> different. <br /> The estimated average costs per tree by type of treatment are as follows: <br /> Cabling $ 980. <br /> Pruning $ 850. <br /> Shaping & Balancing .....$785. <br /> Crown Reduction $850. <br /> Aphids .$850. <br /> + Tree Root Nutrients $485. <br /> + <br /> Cabling - -- This means structurally securing limbs, trunks, or scaffolds to <br /> other tree members for the purpose of stabilizing, holding together, and <br /> decreasing the potential for structural failure of the tree. On this project, we <br /> suggest the use of Cobra system cabling, (the most installed cabling system <br /> in Europe), because it is adjustable over time and can be reused. <br /> 1 <br /> Pruning - -- For these trees, pruning consists of reducing the tip loading (end <br /> weight) of potentially hazardous lateral scaffolding and branches, which <br /> might also affect the structural stability and integrity of the trunk. Pruning is <br /> also used for the reduction of windsail and weight. <br /> Shaping & Balancing - -- This technique balances the structure of the tree <br /> through correct pruning techniques by bringing the center of gravity of the <br /> tree closer to its center and shaping the tree so it would not look like a <br /> wishbone. We recommend allowing the sprouts, epicormic shoots (suckers) <br /> to grow within reason, and not stripping them from the keeper trees from <br /> now on. Within reason, leave all branches that grow parallel to the road <br /> (that were unnecessarily removed in the past), to allow more natural shapes <br /> to form. <br /> ) Crown reduction (recentralization) - -- This allows the branches, <br /> epicormic shouts, and sprouts to grow and photosynthesize within the central <br /> i) <br /> I) 7 <br /> I) <br />
