I have a 500 square foot patio that I installed in the back of my house 2 years ago. I've brought it topsoil and seeded it, but it hasn't done very well as even after 2 years, I'm having difficulty getting grass to grow, which is primarily due to dog/foot traffic. Do you have any suggestions for some common landscaping around a rectangular patio? I don't know if I want to put mulch all the way around it with some shrubs or how successful I'd be in putting sod down around the edges. I think going with something like a mulch project would just result in my dog digging into it and I want to do something quickly as it'll be muddy dogs if I don't. Any advice would be greatly appreciated.
