Data Story
About Lawn Care in Newton County, Arkansas
Newton County: An Oasis of Easier Lawn Care
Newton County boasts a lawn difficulty score of 56.4, making it significantly easier to maintain than both the state and national averages. Its location in Zone 7b offers a more temperate environment for a variety of grass types.
Cooler Summers and Moderate Growth
Unlike most of Arkansas, Newton County only sees 9 extreme heat days per year, far below the state average of 64. This cooler climate results in 3,722 growing degree days, allowing for a more manageable mowing schedule compared to southern neighbors.
Addressing High Soil Acidity
Despite the favorable climate, the soil pH of 5.23 is quite low and requires active management. With 41.6% sand, the soil provides decent drainage, but you must monitor nutrient levels closely as they can leach away in the 56.3 inches of annual rain.
Managing 20 Weeks of Drought
The area experienced 20 weeks of drought in the past year, with 72.2% currently in Severe Drought. Even in this cooler climate, installing a rain barrel can help you maintain your lawn during these extended dry periods.
Versatile Options for Zone 7b
The cooler summer allows for transitional grasses like Tall Fescue alongside warm-season varieties. Plan your seeding around the April 7 spring frost date to ensure your lawn takes root before the fall frost arrives in early November.
