There are generally 3 types of grasses.
Cool Season Grasses
On average, these climates have cold winters and warm/hot summers. Usually they also have regular intervals of rain throughout the summer months, but grasses will tolerate some extended periods of draught by going dormant. Typical types of grass types include:
Bent grass, Bluegrass (KY), Bluegrass, Fescue (red), Ryegrass, Ryegrass
Typical Transition Zone Grasses
There is a “transition zone” between northern and southern turf grass regions, which follows the lower elevations of Virginia and North Carolina west through West Virginia, Kentucky, Tennessee and Arkansas and includes parts of southern Ohio, Indiana, Illinois, Missouri and Kansas. In this transition zone, neither Warm Season nor Cool Season type grasses are uniformly successful. However, several of the Cool Season type grasses such as Kentucky bluegrass and perennial ryegrass and tall fescue, do well across Kentucky, Virginia, West Virginia and Missouri. Tall fescue is the best choice in Tennessee, North Carolina, northern Georgia, northern Alabama and the Texas panhandle. In the lower elevations of these latter states Warm Season grasses do well too. Typical grass types suitable for the Transition Zone include:
Bluegrass (KY), Fescue (tall), Ryegrass (per), Thermal Blue, Zoysia
Warm Season Type Grasses
In some ways, growing and maintaining a good-looking lawn in the South is more involved than for northern homeowners. Choosing a grass type is trickier; many turf grass varieties do much better when started as plugs or sod than from seed, as is usually done with Cool Season turf-type grasses. Good soil is critically important for growing a low maintenance lawn in this region. Most all Warm Season grass types will turn brown when cooler temperatures arrive. Some southern gardeners seed their existing lawns with ryegrass each fall to maintain green color during the winter months. Typical Warm Season grass types include:
Bahia, Bermuda, Buffalo, Carpet, Centipede, St. Augustine, Zoysia
Correct Mowing Height
Lawn mowing is simple enough but if you are cutting your lawn too short you are damaging the leaf blade and making it hard for your lawn to develop correctly. On the other hand if you are letting your lawn grow too tall you are probably removing too much of the leaf blade when you cut. A general rule is to not remove more than a 1/3 of the leaf blade at once. This allows the leaf blade to heal correctly and fight off lawn disease. Mowing your lawn often is also an important way to ensure a healthy beautiful lawn. Mowing your lawn frequently helps to keep your lawn healthy and encourages rapid new growth.
