Actually, you got it on the cement idea Wheedwhacker- one area I need to do this with is the side of our yard where bedroom windows are and neighbors are right next to that so there's nothing it can be used for. Planning on having cement put in but can't afford it yet. And yep- I'm going to look into (eco-friendly) herbicides if I get a reasonable amt of weeds popping thru!
Thanks for your input!
