Our business is built around top-quality tree pruning by trained, skilled professionals. Tree pruning is what we love to do - and it is what we do best.

We will make recommendations for the most appropriate types of pruning based on many criteria, including the species of the tree, the health, age, and size of the tree, and the goals of the property owner.  We strive to retain as much live foliage as possible when pruning, to give the plant the utmost ability to recover from the procedure. It is better to take a small amount of foliage intermittently than a large amount all at once.  Our ultimate goal in pruning is to work with, rather than against, nature.

There are 4 main types of tree pruning as defined by the ANSI A-300 Pruning Standard:

Clean: Selective removal of one or more of the following: dead, diseased, and/or broken branches.  This is the most fundamental of all tree care operations, appealing to any homeowner interested in the long-term health and beauty of their trees. Dead wood can represent a significant hazard in high traffic areas such as backyards where kids play. Diseased or broken branches can provide pathways into the rest of the tree for insects and wood decay fungi. It is best they be removed by proper pruning cuts to allow for natural healing by the tree.

Raise: Selective pruning to provide vertical clearance.  This may involve removal of entire limbs or portions of limbs where the tree is interfering. This is commonly done to provide clearance for people or vehicles, or to allow more ambient light to reach the ground under and around the tree.

Reduce: Selective pruning to decrease height and/or spread. This is commonly used to either pull a tree back from a structure (i.e. house or garage) or to keep an ornamental tree at a prescribed size and shape. Again, we strive to remove as little live foliage as possible to optimize recovery of the plant, balanced with the owner's goals and vision for the landscape. Note that “crown reduction” of mature trees is never recommended and will usually make a tree weaker in the long run.

Thin: Selective pruning to reduce density of live branches. This can provide for increased air flow throughout the entire crown as well as a restoration of natural growth form. Thinning is frequently over-used in dense crowns that have not been maintained in the past, a procedure which can greatly stress a tree. Care must be taken to ensure that trees are not over-thinned.


We will balance stated pruning goals with the health of the tree by removing no more than 25% of the live crown in any one growing season, as per ANSI A300 Best Management Practices.
