in my back yard prior to laying sod My back yard is full of wild grasses and a lot of different types of weeds. I have thought about spraying the yard with Round Up to try and kill everything. What is the best way to get rid of all this crap? Do I need to pull everything out or can I just lay sod down on top of evrything? Should I take a tiller and til it all up and then rake it all out?

Dogs urine. If u have one make your dog urine in the backyard;;
