Data Story
About Lawn Care in Tishomingo County, Mississippi
The State's Cooler Corner
Tishomingo County matches the state difficulty average with a score of 30.1. Located in the northeastern tip in Zone 7b, this area experiences the mildest summers in Mississippi, offering a unique climate for lawn care.
Ample Rain and Mild Summers
The county receives 62.3 inches of rain, well above the state average of 59.5 inches. With only 41 extreme heat days—the lowest in this group—and 4,547 growing degree days, lawns face less thermal stress than anywhere else in the state.
Highly Acidic and Sandy Soil
At a pH of 4.93, Tishomingo has some of the most acidic soil in the region, falling far short of the 6.0-7.0 ideal. The 49.7% sand content ensures fast drainage, but the extreme acidity must be addressed with lime to support healthy root growth.
Monitoring Moisture Levels
The county spent 25 weeks in drought last year, though currently only 62.2% of the area is abnormally dry. Given the high sand content, lawns can dry out quickly despite high annual rainfall, making consistent soil monitoring essential.
Best Window for North Mississippi
Zone 7b allows for a wider range of grasses, including transition-zone species like Tall Fescue in shaded areas. Wait for the final frost on April 9 to start your spring lawn care before the season ends on October 28.
