Any ideas how I can cheaply transform my very ugly back yard? It's quite large - c. 10m x 5m of crumbling old concrete. I've done what I can with planting - I have big raised beds and pots, but there's still SO MUCH CONCRETE! I guess I'm looking for a cheap way that I can landscape it somehow. I rent, and the landlord isn't going to pay to dig it up and put in a lovely lawn, I don't have much of a budget myself, but if there's a cheap way I could put something on top of it, I'd do it, as it would really cheer me up.
