About Lawn Care in Terry County, Texas
Steep Challenges on the High Plains
Terry County’s lawn difficulty score of 23.9 is well below the national median and the Texas average of 31.7. In Zone 8a, the combination of sandy soil and low rain creates a very demanding environment for homeowners.
Dry Air and Intense Sun
Lawns here struggle with only 18.1 inches of rain per year, though the 94 extreme heat days are slightly better than the state average. This low moisture level requires significant supplemental watering to maintain any type of lawn.
Navigating Highly Sandy Soil
The soil is 61.5% sand with a high pH of 7.81, making it difficult for plants to retain water and nutrients. Regular additions of organic matter are necessary to improve the soil's structure and support healthy grass.
Severe Drought Affects the Region
Nearly 30% of the county is in severe drought, following 22 weeks of dry conditions over the last year. Deep-soak irrigation methods are critical to reaching roots through the sandy soil during these prolonged dry periods.
Seed After the April 3 Frost
Bermudagrass and Buffalograss are the most resilient choices for these sandy, arid conditions in Zone 8a. Wait until after the April 3 frost date to begin planting to ensure the soil is warm enough for growth.
