Are we talking about gardens or lawns here?? If we're talking lawns, before you do anything, get a soil test. In Oklahoma, Oklahoma State University will do a pretty inexpensive soil test and give you good recommendations for what you might want to amend your soil with or what kinds of lawn grass would thrive.

There are some pretty great local FB groups on lawns and gardens for Oklahoma. I'm sure central TN is the same.
