Warm-Season grasses tend to grow well and flourish in warmer climates, hence the name. Most Warm-Season grasses are grown in the southern region of the United States and various tropical areas. These grasses tend to grow hardiest and best when temperatures exceed 80 degrees F. During the winter months, Warm-Season grasses will usually turn brown and go dormant depending on the drop in temperature. A common reaction to the browning of Warm-Season grasses is to reseed your lawn during the winter months with a Cool-Season grass such as a ryegrass and/or fescue to keep a green looking lawn year-round. In general, Warm-Season grasses are known for being rather tough and durable grasses that require less watering then their Cool-Season counterparts. The potential draw-backs to Warm-Season grasses are their tendency to develop thatch and weeds. With some "creeping" varieties, problems can arise when the grasses grow out of your established yard boundaries and require constant trimming and edging if not properly maintained.
