Mississippi is warm-season lawn country with a long, hot, very humid growing season, and the calendar runs opposite the cool-season North. Centipede is hugely popular here — it's the low-maintenance favorite on Mississippi's acidic, sandy soils — alongside Bermuda on sunny lawns, St. Augustine in shade and along the Gulf Coast, and zoysia for a dense look. All of them go dormant tan over winter and do their growing and feeding from late spring through summer.
Two things define a Mississippi lawn. The first is humidity and disease. The state's muggy, wet summers make it one of the most fungal-disease-prone lawn climates in the country — large patch (brown patch) in spring and fall, plus dollar spot and gray leaf spot in summer. Watering in the early morning, easing off nitrogen at the wrong times, and keeping a sharp blade are the everyday defenses. The second is centipede's special status: it thrives on neglect and the state's acidic soils but is easily killed by over-fertilizing or over-liming — 'centipede decline' is a classic Mississippi mistake.
The calendar inverts the Northern one: a late-winter pre-emergent to stop summer weeds before green-up, a spring scalp to clear the dead canopy, heavy feeding and frequent mowing through the long summer, and a hard stop on nitrogen in early fall so the grass hardens off before frost. Fall pre-emergent handles winter weeds. Time it to the grass's dormancy and the soil temperature, go light on centipede, and stay ahead of the humidity-driven disease.

Mississippi is in the warm-season south group. These states follow similar seasonal logic, though local soil, elevation, and weather still matter.
