Data Story
About Lawn Care in Neosho County, Kansas
Supportive conditions in southeast Kansas
Neosho County earns a 62.9 lawn difficulty score, outperforming both the state average of 59.1 and the national median. As part of USDA Zone 7a, the county offers a slightly longer and warmer growing season than northern neighbors. This allows for a wider variety of grass species to thrive with moderate effort.
Abundant rainfall and long seasons
With 43.4 inches of annual precipitation, the county is among the wettest in the state, often meeting all a lawn's water needs naturally. The 4383 growing degree days signify a robust season, though 48 extreme heat days still require monitoring. Proper drainage is essential to handle the heavy rainfall typical of this region.
Acidic soil and clay textures
The soil pH averages 6.27, which is excellent for grass health and falls within the ideal 6.0-7.0 range. A clay content of 26.7% provides good water retention but can become compacted over time. Regular aeration helps maintain the soil structure and ensures nutrients reach the root zone efficiently.
Watching for late summer dryness
Despite high annual rainfall, 100% of the county is currently classified as abnormally dry. Neosho County experienced 20 weeks of drought over the last year, proving that even wet regions face water stress. Focus on building organic matter in the soil to act as a sponge during these fluctuating periods.
A long window for planting
Zone 7a allows for successful cultivation of both cool-season fescues and warm-season grasses like Zoysia. The growing season stretches from the last frost on April 10 to the first frost on October 29. Start your lawn projects in early spring to take full advantage of the generous 43.4 inches of rain.
