Landscapers San Jose CA | Call Mahan and Sons Inc

In San Jose, dead patches are often a sign of either severe drought stress from underwatering or, ironically, root rot from overwatering. Our first step is a thorough inspection of your irrigation system's coverage and schedule, combined with a simple soil probe test. We'll check for compacted soil, thatch buildup, and signs of common local pests or fungi. This diagnostic approach allows us to pinpoint the exact cause—whether it's an irrigation issue, soil problem, or disease—so our solution is targeted and effective, not just a guess.

Not always. For overwatered lawns in our area, we start by auditing and adjusting your irrigation system to align with San Jose's climate and your soil type. We then implement core aeration to relieve soil compaction and improve oxygen flow to the roots. Often, this is combined with targeted fungicide applications if disease is present and overseeding with resilient grass varieties suited to our region. A full lawn replacement is typically a last resort. Our goal is to rehabilitate your existing lawn to save you time and money.

The most frequent mistake is watering on a fixed schedule without adjusting for the season. Running the same minutes per cycle in cool, rainy spring as in the peak summer heat can quickly lead to overwatering and disease. Conversely, not increasing water in a heatwave causes drought stress. We help homeowners understand their specific soil's drainage and set their controllers to follow evapotranspiration (ET) rates for our zip code, ensuring the lawn gets the precise amount of water it needs, no more and no less.
