Our front yard isn't grass, its a type of crushed rock over our septic drain field. We've created a spiral walks using larger rocks collected from nearby beaches and the homes of our friends. Unfortunately, weeds love this so we're constantly battling weed growth. Weedkiller isn't an option, given my animals (cats, ducks, chickens, even a Houdini bunny now and again) move through the area and said chemicals can be hard on the septic system. So instead, we're salting. Should keep down the weeds and provide something interesting for the critters to lick. I'll get pictures today, its gorgeous out!
