Hiring a qualified tree doctor is important to keep your trees healthy. Incorrect tree pruning can reduce tree health and cause long term damage to your trees. To assure you are hiring a qualified tree doctor look for a tree doctor that is an ISA Certified Arborist or find a tree service that employs ISA Certified Arborists.
Passing the ISA Certified Arborist exam and becoming an ISA Certified Arborist takes time, study, and a commitment to provide quality tree care. An individual that works for a tree service could be considered tree doctor, but a much smaller percentage of tree doctors become ISA Certified Arborists.
ISA Certified Arborists don’t just learn the names of trees that grow in the Tucson area. ISA Certified Arborists learn to identify tree diseases, tree insect pests, how to diagnosis tree problems, how to do cabling and bracing of trees, how soils interact with tree health, and other tree care related topics. These are important qualifications when correct diagnosis of a tree problem is required.
ISA Certified Arborists know that the various species of trees that grow in Tucson should not necessarily be trimmed in the same way. Not only are different tree species trimmed differently, but ISA Certified Arborists take into account the tree structure of individual trees when trimming trees of the same species.
When inspecting your landscape trees most tree doctors and ISA Certified Arborists in Tucson perform a detailed tree diagnosis and many will provide you with a written report on your trees upon request. Tree doctors and ISA Certified Arborists look for tree diseases, tree insect pests, tree structure, tree decay, and if possible, will evaluate the root system of a landscape tree. A detailed tree diagnosis allows the tree doctor or ISA Certified Arborist to make proper suggestions to maintain the health of your landscape trees. The tree diagnosis will also allow the tree doctor to identify hazardous trees and to suggest when tree removal might be necessary.
