Tree pruning is very much a science and an art. Pruning branches without proper knowledge and preparation can cause significant damage to the tree. Cutting the wrong branch could cause serious deformation or even the death of the tree. If done properly, however, pruning can improve not only the look of your tree but also the tree's overall health. Additionally, pruning is crucial for removing dangerous branches that are at risk of falling. Falling branches can cause property damage as well as serious injury to people and animals.
