Tree Care in Larkspur, CA

If you're looking at the trees in your Larkspur yard and feeling a bit uneasy, you're not alone. Many of the problems we see here, from cracked driveways to sudden limb failure, started decades ago when your home was built. Builders in the 1970s often planted fast-growing trees for quick shade and curb appeal, without considering their long-term behavior in our specific Marin County climate. Two classic examples are the Blue Gum Eucalyptus, which drops massive limbs and is highly flammable, and the Monterey Pine, which is prone to catastrophic failure from pine pitch canker and our occasional strong winds. These trees are now 50-plus years old and entering a high-risk phase.

Why Tree Care Matters in Larkspur

Professional tree care here is about protecting a major asset and managing real risk. A mature, healthy Coast Live Oak or a well-placed redwood isn't just beautiful; it has a calculable property value using the industry-standard CTLA appraisal method. More urgently, we must actively manage the pests that define our region. Sudden Oak Death is a constant threat to our native oaks, and the invasive Goldspotted Oak Borer has been found in Marin. Proactive inspection and care are the only defenses. A failing tree isn't just a loss; it's a direct liability to your home and family.

Your Tree's History

The era your home was built, roughly 1971, is the single biggest clue to your tree issues. The landscaping choices of that time favored exotic, fast-growing species that are now ill-suited to their mature size. The Acacias and Monterey Pines planted back then are declining on schedule. Furthermore, the understanding of native ecosystems and water-wise planting was minimal. This means you're likely dealing with trees that are either structurally unsound, invasive, or overly thirsty, all while being at the peak age for major failures. Your tree's history is written in its species and its rings.

Active Tree Threats in Marin County

Sudden Oak Death (SOD) critical in coastal areas

Sudden Oak Death (SOD)

Affects: Tanoak (most lethal), coast live oak, California black oak, Shreve oak, and 100+ other species as carriers

Water mold (Phytophthora ramorum) that causes cankers on oak trunks, leading to rapid death. Spread by rain splash from infected bay laurel leaves. Has killed millions of oaks and tanoaks since 1990s.

What to do: Remove bay laurel trees within 30 feet of valued oaks (reduces spore load). Preventive phosphonate trunk injection on high-value oaks. Do not move infected plant material or soil.

Invasive Shot Hole Borers (ISHB/KSHB) high

Invasive Shot Hole Borers (ISHB/KSHB)

Affects: 100+ species - sycamores, box elder, coast live oak, avocado, willows, maples most affected

Tiny ambrosia beetles that bore into trees and introduce a Fusarium fungus they farm for food. The fungus clogs the tree's vascular system (Fusarium dieback). Entry holes are tiny (< 1mm) but staining on bark is visible.

What to do: Look for staining/gumming on bark (sugar volcano on sycamores, dark staining on avocado). Prune and destroy infested branches. Do not chip infested wood - beetles survive in chips. Contact local ISHB detection program.

Goldspotted Oak Borer high in San Diego

Goldspotted Oak Borer  -  active in Marin County, CA

Affects: Coast live oak, California black oak, canyon live oak

Beetle native to Arizona/Mexico that has established in Southern California. Larvae bore under bark of oaks, killing branches and eventually the tree. First detected 2004, has killed >80,000 oaks in San Diego.

What to do: Do not transport oak firewood. Monitor oaks for crown thinning and D-shaped exit holes. Report to county agriculture department.
