Warm Season Grasses Defined
Warm-season grasses are originally from sub-tropical regions, which is why they thrive in the hot temperatures of the Southern US. The major grasses in this category are Bermudagrass, centipedegrass, St. Augustinegrass, bahiagrass, and zoysiagrass. Bahiagrass grows primarily along the Gulf Coast. Some warm-season grasses are more cold-tolerant than others, which is why zoysiagrass, centipedegrass, and Bermudagrass are often grown in the Upper South, or Transition zone.
Warm-season grasses grow best when temperatures are between 75-90°F, and do most of their growing in the summer.
