We live in Central Indiana and just purchased our home last November. At the time we closed, the hydroseed did not take and the weeds were taking over. We have been told on 5 occasions that the subcontractor was going to regrade our back lawn and hydroseed. This still has not happened. It is now getting so hot. I know it is not the best time of the year to seed. What I need to know is how to take care of the seeding if and when they ever get it done. We also want to overseed and can wait until fall for this. What should we do to help the hydroseed take?
