We currently have a yard at the back of our house. No grass or plants whatsoever. It was used by the previous owner to store his cars so it is a decent size. We have a toddler and would love to make the space more useable with spring on the horizon. We don't have much to spend so we can't afford to dig up the concrete and have it made into a proper garden yet. But it's a cracking Sun trap with high walls for privacy. We are complete novices but we were thinking of some nice bright stuff in tubs? No idea what though. Could we grow any fruit or veggies? Also is there any way we could get a covering to make the floor a little more forgiving if ds falls?
