St. Augustine Lawns

St. Augustinegrass lawn

St. Augustine grass is a warm-season grass with medium density and medium to dark green color. Of all the warm season grasses, it is the least cold tolerant and has the coarsest leaf texture. St. Augustine grass grows best in warm, humid areas that are not exposed to long periods of cold weather. In fact, its lack of cold tolerance is the major limiting factor in determining its use in North Carolina.
