My 13 year old son was charged with painting the back porch. I walked him through what he needed to do and how to do it. I did some of it with him until he got the hang of it.
I told him to come and get me when he needed to clean the brushes. He took it upon himself to clean the brushes without contacting me. He did this by hosing them off on the grass. All of the grass in that area died.

My question is: Am I going to have to tear up all of that soil next year and re-soil or will it be ok on it's own and all I have to do is re-seed?
