I just signed a new client, and he wants me to reseed a portion of his lawn for him. I sprayed it with roundup to kill out the few weeds that were in it, and measured it out at 20' x 55' or about 1100 sq. feet. So what do I do now? I've never reseeded someones lawn before, but I couldnt turn down such a big job. The dirt is not too bad, but its also not a good topsoil. Kind of a dark sand, and its already been rototilled. Can anyone please give me some idea on the procedure I should use, and how much I should charge?
