St. Augustine (Stenotaphrum secundatum) turfgrass is native to tropical regions and is found throughout the southern United States. This warm-season grass has a poor tolerance for heavily trafficked lawn areas and is generally used in home lawns with low usage. St. Augustine grass is usually planted as sod and requires regular mowing and fertilization.
Texture and Density
St. Augustine grass produces a dense, course, dark green turfgrass when properly maintained at a height of 3 to 4 inches. The rich, full appearance of St. Augustine grass makes it a popular choice for home lawns.
St. Augustine grass has a deep root system that enables the turfgrass to survive periods of prolonged drought conditions. However, weekly watering is recommended for optimal color and health.
St. Augustine grass can tolerate shady lawn environments but will have a thinner, less dense appearance. Like most warm-season grasses, St. Augustine prefers direct sunlight.
As long as the topsoil is well-drained, St. Augustine grass is widely tolerant of pH conditions ranging from 5 to 8.5. Additionally, St. Augustine grass is highly tolerant of saline soil conditions.
Lots of Varieties
St. Augustine grass has many specialized varieties that are better adapted to specific lawn environments. Many varieties are more tolerant of cold weather, shade and infertile soil conditions.
