Quick tips on lawn overseeding:
1) Cut the grass first - mowing the lawn shorter than normal makes it easier for the seed to get to the soil. Ideally, you want to wait two to three weeks after seeding to mow the lawn again. This allows the new grass time to establish roots
2) Rake bare areas - loosening the top layer of soil makes it easier for new grass to take hold. A very thin layer of soil to cover seed also helps (keeps new seed from drying out).
3) Water - the most important step is to water the lawn. Water two to three times a day until new grass is about an inch tall. you do not need to use a lot of water, just enough to keep the seed moist.
4) Know what type of seed you use - Rye grass usually sprouts in 4 to 9 days. Fescue grass in 7 to 14 days. Bluegrass can take anywhere from 10 to 28 days. This will give you a good indication of how long you will need to water.
5) Starter fertilizer - Phosphorus helps the roots grow and is the most important nutrient in starter fertilizer, so the middle number should be the highest ( ie 5-10-5, 20-24-4).
