I just put in a sexy new septic tank & leach bed and need to do some serious seeding. We used the surplus soil to level out irregularities on the surface... so I have much seeding to do. It's all pretty much full sun, and by ISU extension recommendations, looks like there are some good Kentucky Bluegrass cultivars to pick from. We are in S.E. Iowa and under extreme drought conditions. The soil surface is rough and looks like it would be a good time to seed, so that when in rains... the seed will work in and the water would settle the soil around it. Should I: 1) go ahead and put seed out now, 2) wait until there is rain in the forecast, 3) Wait until it actually rains or 4) Other suggestions?
