About Lawn Care in Kings County, California

Overcoming Difficulty in Kings

Kings County earns a lawn difficulty score of 19.4, indicating it is much more challenging than the California average of 51.3. Homeowners in this Zone 9a region must use smart strategies to keep their lawns green.

Intense Valley Sun and Dryness

The county faces 116 extreme heat days each year, coupled with a low annual precipitation of just 7.8 inches. These conditions create 5,373 growing degree days, which translates to high water demand and frequent mowing.

Alkaline and Sandy Soil

The soil pH is 7.50, which is slightly above the ideal 6.0-7.0 range for most turf. With 45.4% sand, the ground drains quickly, meaning you will need to water more frequently to keep the roots hydrated.

Consistent Drought Pressure

With 32 weeks of drought recorded in the past year, your lawn needs a conservation-first approach. To improve resilience, avoid over-fertilizing during dry spells, as this can increase the plant's need for water.

Timing Your Kings County Lawn

Bermuda grass is well-suited for these conditions, providing excellent heat tolerance and durability. Start your seeding after the February 19 frost to take advantage of the spring growing window before November 27.
