We just purchased a foreclosure here in Birmingham, AL that has a decent sized backyard...unfortunately it's almost completely covered in weeds or just has huge spots with no growth (just dirt). So, I'm trying to figure out the best way to get rid of the weeds and grow a healthy lawn in its place. Attached below are some pictures of my "situation." My goal here is to have as much usable lawn space as possible, but I understand I may need to get creative with some flower beds at the base of some of the trees (suggestions welcomed there as well). So, any suggestions on what I should do to start addressing this?
