I want to experiment with my lawn. It has a variety of grasses and weeds. My hope (dream) would be to get a seed that I could consistantly overseed with until I eventually have a nice and consistant stand. I'm in E.Tn. at 1000ft. Another hope (fantasy) is to conduct this experiment with no aeration, sprays, etc., just seed and water and a mulching mower. Any suggestions on seed type to try?
