If Ortho "Ground Clear" is any kind of sterilent, it could leach under and along the edge of your patio and kill grass roots.

'Could call your local nursery to see what they offer given your situation.

I could almost care less. Most of my grass is "overgrowing" the paito anyways. If it doesn't kill my entire yard with a small dose then I would try it.....
