I bought a home recently in the Phoenix area and I want to remove what remains of the front lawn and replace it with a desertscape motif using decomposed granite for the substrate. The house sat vacant and abandoned for more than a year and the weeds and crabgrass staked their claim. Can I -- or should I -- install landscape fabric to discourage the persistent weeds prior to laying the granite? Do's and Dont's?
Thank you in advance.
