Check Your Dirt Before Planting
While specific soil texture data is unavailable, the high heat and low rain suggests a need for organic matter to improve water retention. Conduct a home soil test to determine if your yard requires specific nutrient amendments.
Focus on Evening Watering
Heavy drought pressure hit the county for 32 weeks this past year, though current conditions show temporary relief. Prioritize evening watering to minimize evaporation during the intense Central Valley summers.
Resilient Grasses for Central Valley

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Overseed with ryegrass for winter color
