For the seed to establish quickly, the site must be properly prepared. Make sure there is a layer of loose topsoil so the germinating grass seed will have an easy time establishing and developing its roots.
Select a seed mix appropriate for your area and one that contains a small percentage of annual grass seed. The annual grass will not come back the following year, but germinates quickly and helps to hold the soil in place while the perennial grasses are establishing.
To hold the seed in place while it is germinating, a covering should be placed over top of it that will allow for light, air, water and nutrients to penetrate while giving the seed some protection form erosion and scavenging birds. A cover of straw or a jute mesh covering can be applied over top of the germinating lawn. Both will decompose over time.
