For instance, you can have a very shady landscape or a high quality lawn, but not both. Grass does not grow well in the shade. A good lawn is possible when you plant a proper mix of grasses. Most lawns are combinations of Kentucky bluegrass, creeping red fescue, and perennial ryegrass. A mixture of three different grass species provides the maximum amount of pest resistance and environmental adaptability.
Kentucky bluegrass is the most common lawn grass.
Blends of Kentucky bluegrass cultivars can provide a very high quality lawn, but such lawns usually require above average maintenance levels. The spreading growth habit helps fill in bare spots, but the grass goes dormant during hot, dry, summer weather. This does not mean the grass grows only in shade or that it will tolerate total shade. It grows well in full sun and, in fact, requires some sun during the day. Only named cultivars of perennial ryegrass should be used in lawns.
