Tree Trimming & Pruning

Why Trim/Prune Your Trees?

There are numerous benefits. Regular preventative tree care is less costly than postponed treatments for fully developed problems or taking the risk of awaiting a tree hazard to occur. Trimming / pruning helps maintain and promote health and vitality which will add to the aesthetic value of your tree. This is done by using modern equipment, well trained personnel with state of the art techniques. Trimming / pruning is a process of maintaining the desired density of foliage, shape and size of the tree which involves the removing of branches that are dead, damaged, overcrowded, or rub together, branches that are also infected with disease or insect infestation. Managed Trimming / pruning helps prevent injuries and property damage due to limb failure by improving the branch structure and removing weak tree limbs. In closing properly trimmed / pruned trees are pleasing to the eye, healthier, and equity to your landscape or property.

trimmingThere are four basic terms of tree pruning techniques through the ISA (international society of arbor culture).

Cleaning: which is removal of dead, dying, diseased, crowded, weakly attached, and low vigor branches from the crown of the tree.

Thinning: is selective removal of branches to increase light penetration and air movement through the crown. Thinning opens the foliage of a tree, reduces weight on heavy limbs, and helps retain the trees natural shape.

Raising: removes the lower branches from a tree in order to provide clearance for buildings vehicles, pedestrians, and vistas.

Reduction: reduces the size of the tree often for clearance of utility lines or vistas. Reducing the height or spread of a tree is best accomplished by pruning back the leaders and branch terminals to lateral branches that are large enough to assume terminal roles( at least one third the diameter of the cut stem.) Compared to topping, reduction helps maintain the form and structural integrity.


However, if you would like to get really technical, here are the four pruning classifications adhered by the TCIA (tree care industry association).

Class 1: Fine Pruning

Fine pruning is recommended for premium quality work with an emphasis on aesthetic considerations in addition to structural enhancement. Fine pruning consists of the removal of dead, dying, diseased, decayed, interfering, objectionable, obstructing, and weak branches, as well as selective thinning to lessen wind resistance. The removal of such described branches is to include those on the main trunks, as well as those inside the leaf area.

Class 2: Standard Pruning

Standard pruning is recommended where aesthetic considerations are secondary to structural enhancement and tree health concerns. Standard tree pruning consists of the removal of dead, dying, diseased, decaying, interfering, objectionable, and weak branches, as well as selective thinning to lessen wind resistance.

Class 3: Hazard Pruning

Hazard pruning is recommended where safety considerations are paramount. Hazard pruning consists of the removal of dead diseased, decayed, and obviosly weak branches, two inches in diameter or greater.

Class 4: Crown Reduction

Crown reduction consists of the reduction of the tops, sides or individual limbs. This practice is to be undertaken only for the following reasons:

A. In situations where branches interfere with utility lines.
B. When there has been significant crown dieback.
C. When it is necessary to achieve specific topiary training or dwarfing.
D. In cases where, due to storm damage or prior incorrect pruning, it is appropriate to trim for safety and aesthetic reasons.
