The Art and Science of Proper Pruning

While trimming small trees in the yard may seem like a simple DIY project, pruning is much more than simply sawing off limbs or giving the tree a "haircut" by removing outer foliage. If too much live tissue is removed, an otherwise healthy tree can become stressed or decline.


Proper pruning is based on the scientific principles of plant physiology. It promotes beneficial growth, improves plant health, removes damaged limbs and can increase flower and fruit production (if desired). Together, these benefits enhance the aesthetic appeal of your tree and add value to your property.

At Tree133, we use scientifically sound practices to improve tree structure and promote long-term health. We follow best practices from the American National Standards Institute (ANSI A300) regarding pruning methods, techniques and even the tools we use.

Our Certified Arborists follow ANSI standards in all aspects of our work. We are careful to...

  • Retain foliage to protect tree health

  • Preserve branching structure to promote strength and resilience

  • Protect other parts of the tree during pruning

  • Use only non-invasive climbing techniques (no spikes) for pruning

Effective pruning requires combination of scientific knowledge and practical experience. It can feel overwhelming to those not familiar with the techniques.
