Inspired by a similar vegetable wall at Big Red Sun nursery in Austin, Texas, gardening editor Stephen Orr created this outdoor garden. To make it, line the inside of cinder blocks with metal mesh, using gardening gloves to protect your skin against the mesh's sharp edges. Pour cactus soil onto the mesh, and place succulents inside the blocks. Set the blocks outside; water only during severe drought conditions.
