Data Story
About Lawn Care in Hughes County, Oklahoma
A Challenging but Rewarding Lawn Climate
Hughes County holds a lawn difficulty score of 45.7, which is nearly identical to the Oklahoma state average of 46.1. This indicates a moderately difficult environment compared to the national median of 50.0. Homeowners in this Zone 7b area must navigate both high humidity and intense drought cycles.
Ample Rainfall Meets High Thermal Demand
The county receives a generous 41.3 inches of rain annually, which is significantly higher than the state average of 37.2 inches. However, 78 extreme heat days and 5,244 growing degree days mean that lawns stay active and thirsty. This balance of high rain and high heat can lead to increased disease pressure in the turf.
Silt Loam Soil with Acidic Tendencies
The soil pH in Hughes County is 5.50, meaning it is more acidic than the ideal range of 6.0 to 7.0. The texture is a silt loam, containing 45.9% sand and 16.1% clay, which provides a good balance of drainage and water retention. Lime is frequently needed to raise the pH level and ensure fertilizers are effective.
Battling Extreme Severe Drought Coverage
Nearly the entire county—99.4%—is currently under severe drought conditions, creating a high-stress environment for lawns. This follows a year where the county spent 22 weeks in drought. Despite the high annual rainfall of 41.3 inches, the current lack of moisture requires careful, prioritized irrigation.
Maximize Your Growth in Hughes County
Zoysia or Bermuda grasses are excellent choices to handle the heat and silt loam soils of the region. Plan to begin seeding or sodding after the last spring frost on April 6. Your lawn will likely stay green until the first fall frost, which typically occurs on October 31.
