About Lawn Care in King County, Texas
King's Challenging Turf Environment
With a difficulty score of 24.7, King County is one of the more difficult places in Texas for a traditional lawn. This falls well below the national median score of 50.0.
Intense Heat, Sparse Rain
The county receives just 23.6 inches of rain annually while enduring 114 days of extreme heat. These conditions create 5,565 growing degree days that can quickly scorch sensitive grass varieties.
Sandy Soil and High pH
The soil features a high sand content of 46.2%, which allows for fast drainage but poor water retention. A pH level of 7.54 means homeowners may need to add organic matter to improve soil health.
Severe Drought Persistence
Severe drought currently impacts 57.1% of the county, and residents dealt with 28 weeks of drought last year. Water conservation is essential, as 100% of the county remains abnormally dry.
Resilient Grasses for Zone 8a
Buffalo grass is ideally suited for these sandy, dry conditions. To ensure the best start for your lawn, wait to plant until after the final frost on April 5.
