Kentucky bluegrass can be used for home lawns, recreational areas and is an excellent turf for athletic fields and golf courses. Depending on variety, it can have a low to high maintenance requirement but does make an attractive lawn. Kentucky bluegrass can be grown alone or in combination with other turfgrasses. The most commonly used turfgrasses in mixtures with Kentucky bluegrass are perennial ryegrass, tall fescue and fine fescue. Because of the ability to form a dense sod, it is commonly used in sod mixtures with tall fescue.
Kentucky bluegrass, Poa pratensis L., is a cool season, perennial turfgrass. Kentucky bluegrass spreads by rhizomes and tillers, which allow it to form a dense sod. It will grow in full sun to partial shade and has excellent mowing quality. With a dark green color and a fine leaf texture, Kentucky bluegrass has excellent wear and cold tolerance and moderate resistance to heat and drought. In extreme periods of heat and drought, Kentucky bluegrass will go dormant with growth continuing when moisture becomes available and temperatures subside.
Kentucky bluegrass is adapted throughout Canada down though the transition zone and into higher elevations in the southern United States.
