Is your lawn sunny or shady? Warm-season grasses grow best in southwest Mississippi. All warm-season grasses tend to turn brown in cold weather. (Many homeowners and commercial lawn care firms overseed the warm-season grasses with ryegrass over winter to get a good green color.)
Types of warm-season grasses adapted to your area are Bermudagrass, centipedegrass, and St. Augustinegrass.
