Pruning

All of our pruning operations are performed to meet or to exceed International Society of Arboriculture Standards. The work is performed by / or supervised by our own I.S.A. Certified Arborists using the safest and most efficient manner possible. The various descriptions of our pruning services are outlined below.

Corrective Pruning: The removal of branches for the purpose of maintaining and promoting tree health and structure. This includes the removal of dead, dying, diseased, interfering/rubbing, structurally weak and hazardous branches; trunk suckers; and excessive water-shoot growth.

Thinning: The selective removal of branches within an overcrowded canopy for the purpose of increasing canopy air circulation and sunlight penetration. During the thinning process, care is taken to maintain an evenly spaced branching system and to retain the tree’s natural shape. No more than 25% of a tree’s leaf bearing canopy shall be removed during a single pruning operation.

Canopy Elevation: The removal of low hanging branches to provide desired and appropriate height clearances from people, vehicles, and/or building structures. By “raising the canopy” this also provides for more light penetration. Please note that canopy elevation is not intended nor should it be interpreted as a means of eliminating the tree’s entire canopy from overhanging roof lines or property lines.

Mature Tree Pruning: Usually is restricted to the removal of deadwood and/or potentially hazardous branches. The removal of large diameter branches in mature trees is strongly discouraged since these trees generally have less stored reserves to quickly seal over pruning cuts. Subsequently, these large diameter pruning cuts over time often develop stem or trunk cavities. These cavities form because the rate of decay has exceeded the tree’s rate to contain the infection caused by its long exposure to an open wound.

Proper Pruning Cuts: Trees do not heal when they are pruned. If pruned properly, they will build a chemical compartment behind the wound to prevent fungi, bacteria and insects from entering the tree. A correct cut leaves the branch collar and the branch bark ridge, behind which, the compartmentalization occurs. An incorrect cut removes the collar and the bark ridge, or leaves a stub, allow¬ing decay to begin and progress systematically through the plant.

Spurs: A spike-like tool worn over a work boot to assist in tree climbing. Because spurs create hundreds of entry points for insects and diseases, they are to be used only for the removal of trees.
