Tree Health Evaluation


Regular tree health evaluations can catch changes in a tree’s health and vigor before a disease, insect, or environmental problem becomes too serious to address.  Ideally, mature trees should be inspected at least once a year to assess tree health and vigor looking at leaf size, twig growth, growth of reaction wood and presence of crown dieback.  Reduction of normal growth is a fairly reliable cue that the tree’s health has recently changed, and an experienced arborist can look at twig growth from past years to determine whether there is a reduction in the tree’s growth pattern.   Loose bark, deformed growths, and conks (mushrooms) are common signs of stem decay and should be inspected further to determine the extent of decay.  Any abnormalities found during Tree Health Evaluations, such as insect activity and/or spotted, deformed, discolored, or dead leaves and twigs, should be noted and monitored closely.  As part of a Tree Health Evaluation, a plan detailing tree care practices will be developed to maintain or increase health of the tree.
