I have sown this yard twice without much success. The house is for sale and I need to do something to help the front yard. Its about 60% covered in a nice grass/weed mixture and about 40% bare dirt. I am trying to get this done as cheaply as possible. Should I just try and rough up the soil and overseed or till it all and resow? Assuming I till and resow when is the optimum time to do so in west Tn, if one is wanting to do it in spring instead of fall? The soil here typically requires lime, so I intend to spread lime, sow, fertilize and water. Anybody have some tips on how I can maximize growth while minimizing cost?
