Data Story
About Lawn Care in Fayette County, Tennessee
Challenging Conditions in Deep Southwest Tennessee
Fayette County is a difficult environment for lawns, scoring just 34.6 on the ease-of-growth scale. As the only county in this group in zone 8a, it faces more intense southern heat than its neighbors.
Combating 61 Days of Summer Heat
The county experiences 61 extreme heat days, far exceeding the state average of 36. High heat and 5152 growing degree days mean lawns can quickly become overgrown or heat-stressed without constant care.
Treating Acidic Silt Loam Soil
A soil pH of 5.28 means the ground is naturally too acidic for many grass types to thrive. This silt loam is moderately well-drained, but the low sand content (17.7%) suggests that compaction can still be an issue.
Irrigating Through 19 Weeks of Drought
Lawns faced 19 weeks of drought last year, and 100% of the county is currently abnormally dry. Maintaining a taller mowing height can help shade the soil and reduce water loss during these intense dry periods.
Best Grasses for the 8a Zone
St. Augustine or Centipede grass are strong options for this warmer climate zone. Ensure your lawn is established after the April 1 frost and remains healthy through the first fall frost on November 3.

- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
