What Is Tree Trimming?

Tree trimming is the selective removal of branches from a tree in order to improve its health and appearance. It is a key part of tree maintenance, often performed in order to prevent branches from interfering with power lines, obstructing views or creating hazards on property. It also helps to promote balanced growth and healthy trees in the landscape, as well as ensuring that they remain structurally sound.

When and how often to prune a tree varies based on species, personal preference, and the goals of the owner. Young trees require more frequent pruning to establish their structure and canopy size, but this will reduce as they mature. Most mature trees can be trimmed every 3-5 years.

A thorough pre-trimming assessment is conducted to determine the health and structure of a tree before any cuts are made. This ensures that the correct cuts are made to achieve the desired outcome. It is important to note that pruning should only be done by qualified professionals as improper cutting techniques can lead to serious consequences.

The most common pruning goals include removing diseased, dead or broken branches, thinning overcrowded areas of the crown, reducing branch lengths to eliminate limb interference with buildings or traffic, and promoting good air circulation and light penetration through the tree. Other objectives may be to open vistas, repair storm damage, and provide clearance for structures and traffic.

Ideally, the pruning of all trees and shrubs should be performed in a manner that is consistent with their natural form. It is important to avoid trying to shape a round-topped or ascending tree into a formal upright style, as this will likely result in long-term problems. Other undesirable forms of pruning can be reduced by removing inward-growing branches, crossing or rubbing branches, water sprouts from limbs, narrow V-shaped crotches, and the excessive lowering of crowns.

When and where to prune a tree varies based upon season and species. In general, it is best to prune spring-flowering trees and fruit trees right after they finish blooming. This allows the tree to set new buds for the following year without sacrificing the beautiful blossoms. Summer-flowering and fruit trees should be trimmed in late winter or early spring while they are dormant to encourage new growth before the growing season begins.

Topping, or cutting main branches back to stubs, is discouraged as it disrupts the natural form of the tree, forces weak new growth that is prone to breakage, and can lead to decay and insect infestation. A good rule of thumb is to only remove one-fourth of a branches total leaf-bearing capacity per season.

The heaviest limbs of a tree are best removed with a saw, but for branches above 20 feet it is recommended to have an arborist perform the trimming. Properly pruning a tree will help to maintain its health and beauty and increase the value of your property. A professional tree care company will have the knowledge and equipment to safely trim trees and shrubs in the landscape and can provide a full range of services for your home or business.
