Bluegrass
Bluegrass is a long lived perennial grass, a cool season species that grows best when thetemperature is between 60 and 75 degrees and the precipitation is between 20 and 50 in.per year. It spreads by tillers and rhizomes and produces an extremely dense sod with roots penetrating as deep as 1 1/2'. These characteristics make it the premier lawn grassin our area. Bluegrass is able to withstand hot, dry periods, usually going into dormancy and losing its green color, but it recovers when adequate water is supplied.

Perennial ryegrass
Perennial ryegrass is a cool season bunch type grass that is a quick germinator and can be used as a temporary ground cover while the slower growing bluegrass plants take hold. Fine leafed ryegrasses blend well with bluegrass and are indistinguishable by most people, are best adapted to moist, cool environments where temperatures are not extreme in the winter or summer. The mix of bluegrass and perennial ryegrass has a better response to disease than either grass has alone. 

Tall Fescue
Tall fescue is a coarse textured and deeply rooted perennial bunch grass with a relatively high disease resistance and heat and drought tolerance. Turf types have finer leaves, more dense tillering, and frequently a darker green color than the original tall fescues.

Bentgrass
Bentgrass is a fine leafed, low growing, cool season grass that is considered the preeminent grass of the turf world. Originally meant for golf course greens, not for the typical home lawn because of its high maintenance requirements. It will tolerate very lowmowing 1/4", repeated every 1 to 2 days.
