About Lawn Care in Covington County, Mississippi
Covington's Southern Lawn Challenges
Covington County earns a lawn difficulty score of 32.1, making it slightly easier than the state average but still a challenge. Located in Zone 8b, your lawn must endure intense heat and humidity compared to the rest of the nation.
High Humidity and Growing Cycles
The county receives 59.1 inches of rain and 70 extreme heat days, typical of a high-stress Mississippi climate. With 6,289 growing degree days, the growing season is long and fast-paced, requiring diligent mowing and care.
The Need for Soil Amendments
The soil pH is very low at 5.04, which can severely lock up nutrients and stunt your lawn's growth. Because the soil is nearly 48% sand, you will need to add lime and organic matter to help the ground hold onto water and food.
Unusually Stable Moisture Conditions
Covington is currently free of any drought designations and recorded only one week of drought over the past year. This makes it one of the most moisture-stable counties in the state for the current season.
Getting Started in Covington
Centipedegrass and Bermudagrass are your best bets for these acidic, sandy soils. Plan your planting after the March 17th frost to give the grass plenty of time to establish before the first frost in mid-November.

- 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
