Tall fescue is often used to improve a lawn because of its versatility. Tall fescue does best in environments with high rainfall, but it is quite drought tolerant. It can be grown in nearly any type of soil and thrives in clay soils, which can be difficult to plant. When used to reseed a lawn, tall fescue not only thickens turf but adds character and dimension to the landscape.
Mow a third of the grass' height and remove the clippings.
Rake the surface of the soil with a stiff iron rake. By scratching the soil, you give the seed a place to settle.
Aerate the lawn with a spike aerator. Move north to south across the lawn and then make a second pass from east to west.
Spread the tall fescue over the seed by hand (for larger lawns, rent or purchase a seed broadcaster and calibrate it to the desired application rate). The application rate should be 6 to 12 oz. per 100 square feet depending on the amount of bare soil you have to cover in certain areas of your lawn. The best way to hand broadcast is to measure the desired amount per 100 square feet into a small container. Mark off 100 square feet of lawn and evenly sprinkle the seed over the area.
Cover the tall fescue seed with 1/4 inch of potting soil.
Roll a lawn roller over the lawn to make sure the tall fescue seed makes firm contact with the soil.
Water the planting area and keep it moist for the next one to three weeks until the seed germinates. Then gradually reduce the watering frequency until you are following your normal watering schedule.
Use a fertilizer spreader to spread a complete fertilizer over the tall fescue at a rate of 1 lb. of nitrogen per 1,000 square feet.
