Fescue is a cool season perennial grass that is good for lawns in the cooler regions of the U.S. and the transition regions, like Oklahoma, Arkansas, Missouri, Tennessee, Kentucky and Virginia, according to Texas A&M University. It has deep roots and grows rapidly in the spring and fall. While it grows in moist conditions it can handle drought well for some time by going dormant. According to Colorado State University, Fescue needs about half the water of Kentucky bluegrass.
Water your fescue lawn once a week in the spring with about 1 inch of water for loamy or clay soils and ½ inch of water every three to four days for sandy soils.
Water the fescue with 1 inch of water in the summer every time you water. Only water the fescue when it needs water, such as when the grass is wilting. If there is too much water run off, turn the sprinklers off for a few hours and then turn them back on for another few minutes so the grass absorbs the water properly.
Water the fescue in the fall with 1 inch to 1 ¼ inch of water as it shows signs of wilting. Water sandy soil with ¾ inches of water every three to four days.
Water fescue in the winter with 1 inch of water each time the lawn dries out.
