Establishing a lawn is labor-intensive and often an expensive process. You should seriously consider having a soil test as it is impossible to determine what the existing fertility level of a soil is by looking at it. Once you have established the appropriate fertility and seeded the lawn area, you will want to mulch the area with a light layer of straw to help conserve moisture. After germination, do not attempt to immediately remove the straw. Until seeds germinate and emerge, it is necessary to keep the top half inch of the soil moist. This may require watering every day. After emergence reduce the watering but maintain adequate moisture in the top six inches of soil. Begin mowing the grass as soon as it is high enough to be mowed, and do not remove more than one third of the top growth in a single cutting. Do not cut cool-season grasses lower than three inches.
