The amount of grass seed you need depends on the size of your lawn and the specific grass type. For example, a new tall fescue lawn requires about eight to 10 pounds per 1,000 square feet, while colonial and creeping bentgrasses need only 1/2 to one pound per 1,000 square feet. Accurately measuring your lawn or hiring a lawn care professional ensures you buy the right amount.

It takes between seven and 30 days to reseed a lawn, depending on your local climate and the grass species you use. Proper soil preparation, seeding techniques, and a good watering schedule help ensure your lawn grows healthy and strong within this timeframe. If you require additional prep work, the process may take longer.

Without proper measurements, you can put down too much grass seed. Putting down too much grass seed can harm your lawn by leading to clumping and uneven growth, which may cause disease and nutrient imbalances. Stick to the recommended seeding rates and spread the seed evenly for the best results.

The difference between overseeding and reseeding is that overseeding involves spreading new seeds over an existing lawn to improve its thickness, while reseeding means planting new seeds to replace significant portions of a damaged or dead lawn. Knowing the difference helps you choose the best approach for your lawn's needs.

You should avoid walking on grass seed until the new grass has been mowed three to four times, indicating a strong root system has developed. Early foot traffic can damage seedlings and hinder growth, so limiting access helps your lawn grow healthy and strong. If you must walk on your lawn, try to stick to stepping on stones, boards, or designated pathways.

The best time to reseed your lawn depends on your grass type and local climate. Warm-season grasses should be reseeded in spring or summer, while cool-season grasses do best when reseeded in early spring or early fall. Seeding at the right time helps ensure robust growth and a healthy lawn.
