About Lawn Care in Coahoma County, Mississippi
Coahoma's Average State Difficulty Score
Coahoma County scores 34.2 on the difficulty scale, placing it near the Mississippi state average but well below the national median of 50.0. Maintaining a lawn here in Zone 8a is a moderate challenge for the region.
Lower Rain and High Heat
Annual precipitation of 55.9 inches is lower than the state average, which can help reduce fungal pressure if managed well. However, 67 extreme heat days and 5,457 growing degree days mean your turf will still require a lot of water and attention.
The Region's Most Balanced Soil
Coahoma features a soil pH of 6.07, which is the closest in this group to the ideal 6.0-7.0 range. While the 31.2% clay content provides great nutrient retention, it can lead to drainage issues during heavy rainfall events.
Managing Severe Drought Conditions
The county is currently facing a crisis with 46.2% of the area in severe drought and 100% classified as abnormally dry. After 31 weeks of drought in the past year, strict water conservation is essential for lawn survival.
Success with Zoysia and Bermuda
Zoysia grass is an excellent choice for these clay-heavy soils and warm temperatures. Start your planting after the March 16th frost to give your grass the best chance to mature before the summer drought intensifies.
