Also, the full sun promotes growth. Therefore, Bermuda grass can be cultivated in warm climates. 

What is St. Augustine Grass

St. Augustine grass is another type of turfgrass that is also known as buffalo turf in Australia and buffalo grass in South Africa. The family of the grass is Poaceae. It is popular as a warm-season lawn grass in tropical and subtropical regions. The color of the grass is dark green, and the blades are flat and broad. Runners form a dense layer of the grass. Both sides of the Atlantic Ocean grow St. Augustin grass. The propagation of the grass is by plugs, sprigs, or sod. It can propagate on its own or can be cultivated.
