About Lawn Care in Jackson County, Arkansas

Challenging Conditions in Hardiness Zone 8a

Jackson County's lawn difficulty score of 36.5 is nearly identical to the Arkansas state average but falls well below the national median of 50.0. This zone 8a environment requires more intensive management to keep grass green and healthy throughout the year.

High Growing Degrees Mean Frequent Mowing

With 5,007 growing degree days, lawns here grow rapidly, necessitating a consistent and frequent mowing schedule. The area receives 51.1 inches of rain annually, though 57 extreme heat days often evaporate that moisture quickly.

Well-Drained Stony Silt Loam Foundation

The soil is characterized as well-drained stony silt loam with an average pH of 5.59. This acidic profile requires regular testing and pH adjustments to reach the 6.0 threshold preferred by most turfgrass species.

Adapting to Extreme Drought Cycles

Currently, 100% of the county is in a severe drought state, having endured 30 drought-affected weeks over the past year. Maintaining a higher mowing height can help shade the soil and retain what little moisture is available.

Bermuda and Zoysia Thrive Here

Heat-tolerant varieties like Bermuda or Zoysia are best suited for these 57 annual heat days. Wait for the final spring frost around March 23 to begin your seeding or sodding for the most successful results.
