Why do I need an ISA Certified Arborist rather than a standard tree service?

Hiring an ISA Certified Arborist ensures your trees are evaluated by a formally trained professional who understands the biology and biomechanics of the canopy. We provide science-based pruning, advanced disease diagnosis, and structural risk assessments. Standard landscaping crews often use harmful practices like topping or climbing spikes on live trunks, causing irreversible damage.

Do I need a permit to remove a tree on my property in San Jose?

It depends on the size, species, and location of the tree. San Jose and surrounding Santa Clara County municipalities have ordinances protecting Heritage and Ordinance-size trees, even on private property. We provide the official arborist reports and risk assessments cities require to approve protected tree removals.

What are the most common tree diseases and pests affecting the South Bay?

Sudden Oak Death is a major concern for native oak populations across the valley and Peninsula. We also see severe seasonal outbreaks of Western Tussock Moth caterpillars, which defoliate and stress mature shade trees. Early diagnosis and targeted treatment are critical.

Is it safe to prune or remove trees during the winter months?

Yes. Winter is the dormant season for many local species and ideal for heavy structural pruning. However, winter brings high winds and saturated clay soils, which is when most root failures and branch breaks occur. A structural assessment before heavy storms is the safest course of action.

FAQ

Hiring an ISA Certified Arborist ensures your trees are evaluated by a formally trained professional who understands the complex biology and biomechanics of the canopy. We provide science-based pruning, advanced disease diagnosis, and structural risk assessments. Standard landscaping crews often use outdated, harmful practices—like "topping" a tree or using climbing spikes on live trunks—which causes irreversible damage and makes the tree a future hazard.
It depends entirely on the size, species, and location of the tree. San Jose and surrounding Santa Clara County municipalities have strict ordinance codes protecting "Heritage" and "Ordinance-size" trees, even on private residential property. We are highly familiar with local municipal tree regulations and can help you navigate the process. If a permit is required, we provide the official arborist reports and risk assessments the city needs to approve the removal.
Our local microclimates host a few aggressive, fast-moving issues. Sudden Oak Death is a major concern for our native oak populations across the valley and the Peninsula, causing rapid canopy decline if not properly managed. We also see severe seasonal outbreaks of pests like Western Tussock Moth caterpillars, which can quickly defoliate and severely stress mature shade trees. Early diagnosis and targeted treatment are critical for saving the canopy.
Absolutely. In fact, winter is the dormant season for many local species, making it the ideal time for heavy structural pruning without overly stressing the tree. However, our winter season also brings high winds and heavily saturated clay soils, which is exactly when the highest number of root failures and branch breaks occur. If you suspect a mature tree is leaning or has a compromised canopy, getting a structural assessment before the heavy storms hit is the safest course of action.

Tree care is an investment in your home's value and safety. It takes rigorous training to understand how a single cut impacts the complex biology of a tree years down the line.
