Tree Care in Sebastopol, CA
Why Tree Care Matters in Sebastopol
Professional tree care here is about protecting a major asset. A mature, healthy Coast Live Oak or a well-placed redwood isn't just beautiful; it has a quantifiable property value assessed by industry standards like the CTLA method. More urgently, our specific pest threats, like Sudden Oak Death and the invasive Goldspotted Oak Borer, require proactive management to protect our native oaks. With our 39 inches of annual rain and occasional wind events, proper pruning for structure and health is not an aesthetic luxury. It's a necessary step to prevent storm damage to your home.
Your Tree's History
The landscaping boom of the 1960s to 1980s, when most Sebastopol homes were developed, introduced many non-native, problem species. Fast-growing trees like Acacia and Eucalyptus were planted for quick screening and shade. Now, decades later, these trees are at the age where their inherent weaknesses are showing. They're often too large for their urban lots, with root systems that damage foundations and pavements, or brittle wood that fails in our occasional high winds. This era directly explains why we're now dealing with so many oversized, high-risk specimens.
