Pruning can help with the health and longevity of your tree.
A thinning prune is beneficial to your tree’s health because if the canopy of the tree is over dense it can lead to a lot of problems for the tree in the future. Some of the problems being disease as bacteria and fungi thrive in moist environments which dense canopies can be from lack of airflow. An over dense canopy can consequently be overloaded which increases potential for failure. Perhaps you would like to allow more light into your backyard this can also be achieved through a thinning prune.
Dropping and horizontal branches can cause problems for trees. These branches are often weakly attached and have the highest potential for failure with the forces that mother nature places against the tree’s canopy. Maybe the branches are so low that the branches hit you in the head as you walk by or as you are mowing the lawn or that branch is ruining your perfect view out the window. These problems can be fixed by elevating the canopy for an upright growth form.
For the longevity of the tree it is good arboriculture practice to prune trees when they are younger. Removing problem branches or codominant stems when the tree is young will greatly improve the lifespan of your tree.
Is part of your tree touching or encroaching upon your house or another structure? It is beneficial for both the structure and the tree to create space.
This type of trimming includes any dead, diseased or damaged branches to revitalize the tree. It is good arboriculture practice to trim trees every three to five years depending on species and age.
