As a cool-season grass, fescue grass ranks high on the list of popular grasses, largely because it is so easy to maintain. Once a fescue lawn is established, homeowners should bear in mind, however, that a low-maintenance regimen is required to keep the lawn healthy and growing.
Water established fescue grass when moisture problems---like wilting, rolling leaves or discoloration---are evident. Wet the lawn with a garden hose or sprinkler. Apply one inch of water, which will penetrate four to eight inches deep in the soil. Continue to water fescue every seven to ten days, preferably during the early morning.
Fertilize fescue annually with 2 ½ to 3 pounds of nitrogen for every 1,000 square feet. Apply fertilizer in the fall, as fescue is a cool-season grass, and applying a fertilizer in the summer will encourage excessive growth, pests, diseases and drought stress.
Mow fescue lawns to a height of between 3 and 3 ½ inches. Cut the grass with a rotary lawn mower. Inspect the lawn for pest damage or infestation following a mowing.
Reseed a fescue lawn when it becomes too thin---usually caused by improper watering, too much fertilizer or improper mowing. Inspect the lawn and estimate the amount of fescue that needs to be replaced. Use five pounds of seed for every 1,000 square feet. Apply the seed to freshly mowed grass and follow with fertilizer, one pound for every 1,000 square feet. Water daily to the depth of about 1/8 of an inch for the next three weeks.
