If you are renovating or reseeding your lawn, it's important to pick the right kind of grass for your situation. Consider the following before you choose which grass will work best for different areas of your lawn.
Grasses are sun-loving plants.
They need an absolute minimum of 4 hours of direct sun a day. Areas that get much traffic require at least 6 hours. If your light is marginal, fescues tolerate shade better than bluegrass or ryegrass. If you don't plan to water during summer droughts, or your soil does't retain much water, fescues again are your best choice. Fine fescue doesn't stand up well to traffic.
