Tree Care in San Carlos, CA
Why Tree Care Matters in San Carlos
Professional tree care in San Carlos is about managing risk and preserving value. Our warm-marine climate with 10-month growing seasons and periodic drought stresses trees, making them targets for local pests like the invasive Shot Hole Borer or Sudden Oak Death. A common mistake is using a lawn sprinkler system that runs for 15 minutes daily. This encourages shallow roots, which is the worst thing for a tree's stability and drought resilience. Trees need deep, infrequent watering to develop strong root systems. An arborist assesses the whole picture, from soil moisture to structural soundness, to keep your property safe and your trees healthy for decades to come.
Your Tree's History
The era your home was built directly influences your tree issues. San Carlos saw its major growth from the 1960s through the 1980s. Landscapers and builders of that time frequently planted Monterey Pines for quick screening and Eucalyptus for fast growth. These species are now at an age where their inherent weaknesses are exposed. Monterey pines are prone to sudden failure, and eucalyptus trees drop heavy limbs. The 19 inches of annual rainfall isn't enough for these water-hungry non-natives without proper care, compounding the stress. You are likely dealing with the consequences of 60-year-old decisions made for a landscape that looked very different.
