I went through that phase down here as well when we first moved here. I battled against it until the summer of 2012 where I finally threw my hands up and naturalized my lawn. Now I have oaks and loblolly pines 30-40ft tall covering most of my yard and what grass remains is mostly replaced by moss that stays green all summer, doesn't need mowing or watering. Plus it's a lot cooler with all the shade.
