Mature Tree Pruning
Tree pruning in Phoenix,AZ is required on most mature trees, to remove dead and dying branches to maintain plant health and safety.
This pruning type is referred to as cleaning.
Research has now documented that thinning, the removal of live branches to reduce density, significantly reduces wind resistance and subsequent storm damage.
This is particularly important given the severe monsoon storms that sweep through the valley during the months of July-September. Thinning should only be done on trees where the crown is “too dense” and an Arborist has training and experience to evaluate this attribute. Thinning should be concentrated on the outer portions of the canopy, leaving as many branches on the interior crown as possible.
In some instances, the crown or individual branches require a reduction in length to improve the form and shape of the plant, to eliminate interference with objects and structures, and to compensate for structural weaknesses. Lower branches may require pruning for similar reasons. This process, known as raising, also can be used to increase the amount of light for turf grass and ground covers beneath the crown of a tree.
One aspect of pruning that is most frequently overlooked by consumers is the structural pruning of young trees. Trees in forests tend to grow straight and lose lower branches due to competition for light. When planted in full sun in the landscape, many species tend to develop multiple stems/leaders that are more prone to failure. Lower branches tend to grow at the same rate as the terminal leader that results in weak attachments that also are likely to fail later in the life of the plant. So pruning trees when they are young and growing quickly is critical to ensuring a strong framework for future growth. This pruning focuses on maintaining a single dominant stem unless multiple stem “clumps” are specifically desired. Branches are pruned so their size remains proportional to the stem diameter at their point of attachment. As trees grow, some branches are removed to ensure adequate spacing between permanent scaffold limbs. The shape of the tree is maintained to provide a natural open-grown form typical of the species.
