Tree Health in Palomar Mountain, CA.

Tree Health for Palomar Mountain homes, done by licensed San Diego County arborists.

Mountain diagnosis focuses on pine beetle (bark beetle complex) in conifers and oak borer in hardwoods.

Can you save a tree with beetle damage?

Depends on the beetle and the stage. Early-stage invasive shot-hole borer in willow, sycamore, or box elder can sometimes be managed with systemic injection and cultural changes. Advanced ISHB with extensive galleries is usually terminal. Gold-spotted oak borer in mature oaks is harder, by the time symptoms show, damage is often too advanced. Early diagnosis is everything.

My tree's leaves look bad. Is it dying?

Not necessarily. San Diego trees often show heat and drought stress in late summer, curled leaves, yellowing, early drop. Deep watering and mulching usually turn it around. Real trouble looks different: branch dieback from the tips, canopy thinning, bark slipping. A short site visit tells you which category you're in.
