About Lawn Care in Coffee County, Tennessee
Steady Growth Conditions in Coffee County
Coffee County holds a lawn difficulty score of 54.1, indicating it is slightly easier to maintain a yard here than in the rest of Tennessee. This score outperforms the national median of 50.0 as well.
Coping with Heavy Southern Rains
The county receives a high 60.1 inches of precipitation annually, which is well above the ideal range. However, with only 19 extreme heat days, lawns are less likely to suffer from the mid-summer burnout seen elsewhere in the state.
Well-Drained Silt Loam Foundation
The gravelly silt loam soil is classified as well-drained, which helps manage the high annual rainfall. You may still need lime to address the 5.37 pH, as most turf thrives closer to a neutral 6.0 or 7.0.
Resilient Turfs and Drought Cycles
The county only spent 9 weeks in drought over the last year, despite 100% currently being abnormally dry. This relatively short drought history helps established lawns recover quickly without permanent damage.
Plan Your Seeding for Mid-April
Tall Fescue is a durable choice for this 7b zone, handling the 4,099 growing degree days with ease. Aim to get your seeds in the ground after the April 6th frost date to ensure strong germination.

- 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
- Mow at recommended height weekly
- 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
