About
St. Augustine grass (Stenotaphrum secundatum), also known as buffalo turf in Australia and buffalo grass in South Africa, is a species of grass in the family Poaceae. It is a warm-season lawn grass that is popular for cultivation in tropical and subtropical regions. It is a medium- to high-maintenance grass that forms a thick, carpetlike sod, crowding out most weeds and other grasses.
How to grow it
Only recently has commercially valuable and viable seed for St. Augustine become available, so it has typically been propagated by plugs, sprigs, or sod. Once the grass is cultivated, it can propagate on its own.
St. Augustine can grow in a wide range of soil types with a pH between 5.0 and 8.5. It usually blooms in spring and summer.
Uses
St. Augustine grass is commonly used in pastures and on ranches. It is a popular lawn grass, rivalling bermudagrass, though St. Augustine is somewhat less drought-tolerant.
