what is the difference between kentucky bluegrass and tall fescue?
Fescues grow in bunches that don't form as dense a sod or spread as well as Kentucky bluegrass rhizomes. ... Kentucky bluegrass turf requires more fertilizer and more frequent mowing than fescues. Tall fescue does not require mowing less than 3 inches high, and uses about half as much water as Kentucky bluegrass.
