Best fescue for Lexington/Midway area
Tall fescue or a fescue blend with Kentucky bluegrass will work in the Piedmont. However, right now is not the best time to try and establish a cool-season lawn. The more appropriate time would be August/September. You can seed now if you're looking for quick cover, but there is a chance you may lose some of it if the weather gets very hot this summer because it will not have enough time to develop a strong root system.
