This score indicates a moderately difficult environment that is tougher than the national median of 50.0. Homeowners in this Zone 7b area must contend with significant heat stress to keep grass green.
High Heat and Moderate Rainfall Patterns
The county experiences 88 extreme heat days per year, significantly higher than the state average of 76 days. Annual precipitation of 35.2 inches falls slightly short of the state’s 37.2-inch benchmark. With 5,388 growing degree days, the metabolic rate for turf is high, requiring attentive hydration.
Ideal pH Balanced with Sandy Soil
The soil pH in Grady County is a near-perfect 6.01, fitting right at the threshold of the 6.0-7.0 ideal range. The texture is dominated by 44.1% sand and 15.1% clay, which often leads to fast drainage and nutrient leaching. Frequent, light fertilization often yields better results in these sandy Oklahoma soils.
Combatting Widespread Severe Drought
Severe drought conditions currently cover 65.4% of the county, making irrigation management a top priority. Grady County endured 22 weeks of drought over the last year, taxing even established root systems. Mulching and maintaining higher mowing heights can help retain precious soil moisture during these dry spells.
