Tree Trimming

Regular tree pruning, also commonly referred to as trimming, does more than keep your property looking sharp. It supports long-term tree health by improving airflow and sunlight through the branches, reducing decay and pests, and helping the tree put its energy toward strong growth.

Timing matters, and it's different for every tree. Trim at the right time and you protect the tree's health and keep it growing strong; trim at the wrong time and you can do more harm than good. Not sure when to cut yours? Our arborists can recommend the right timing for its species and condition.

Pruning is also a preventative maintenance measure, clearing weak or overhanging limbs before they become a hazard to your roof, power lines, walkways, or even people. Our arborists can spot warning signs long before they become a real problem.

Below is a quick reference guide including some of the Bay Area's most common trees, including San Francisco's most-planted street trees, with the best season to trim each one and why.
