Answer: After you broadcast the seed, spread a thin layer of peat moss over the the planted area. The peat moss will help keep the seed bed from drying out too fast and it will decompose on its own so you won't need to remove it. In fact, as it decomposes it will release nutrients to the roots of your new lawn.
It's difficult to predict just how often you'll need to water the seedbed. It really depends upon the weather. The important thing is to try to keep it from drying out. You may have to water several times a day (every 3-4 hours if it's windy or the weather is hot). Once the seed has germinated and the blades are actively growing, you can reduce watering to twice a day (again, depending upon weather). Hope this information helps you get your new lawn off to a good start.
