Hey all, I bought a brand new house 2 months ago and want some advice on landscaping the back yard. Colorado is really dry and the ground is hard as hell. Anyway, would like to put in a deck, maybe a guesthouse with a hot tub. So with this arid climate what's a good way to fill the rest of the space, I know rocks.... that's pretty much every house in Colorado. Want something different, got time to save money and plan. Any ideas???
