2. SPREAD YOUR SEED
Use a broadcast or drop spreader to spread seed over the entire lawn according to the product label. There’s no need to overdo it. Only about six seeds per square inch will germinate. Sow the seed too thickly and you’re simply wasting seed.

3. FEED THE SEED
Spread a starter fertilizer over the entire area. They typically contain more phosphorous which helps new seed develop roots.

4. WATER THE LAWN
Lightly mist the overseeded area. Keep it moist with light watering if dew or rainfall doesn’t do it for you. Keep the soil moist by spraying it with a light mist two or three times a day until the grass is about 1" high. Continue to water about once a week until the new grass is about 3" tall.
Why overseed your lawn? It can help thicken your turf and keep weeds from filling in thin or bare spots.
When to do it? This is a great early Fall project. The season’s higher moisture and cooler temperatures helps new turf start strong. 4 Steps
