Tree Pruning

Since suburban landscape environments do not mimic natural forest conditions, our trees require a higher level of care in order to preserve their health, safety and aesthetics.  Typically, pruning is the most common aspect of tree maintenance.  This is done to remove dead branches, crowded and rubbing limbs, and to eliminate hazards.  Pruning is also done to increase light and air penetration and to create a more aesthetically balanced tree.


It is important to understand how different types of trees respond differently to pruning.  Therefore, we do not have a single technique that applies to all trees.  Further, we work within the expectations of each customer and adapt to their individual aesthetic preferences.


Proper pruning, with an understanding of tree biology is necessary to maintain tree health, safety and aesthetics.  Trees that are pruned improperly can sustain damage that will last for the life of the tree and even cause its decline.
