Pulled a boner over the winter. Made a batch of home made ice cream and without thinking dumped 2-3 gallons of leftover salty ice water in the yard. Now I have a 20-30 square foot dead area in my lawn.

My neighbors think it's my dog's fault. I'm letting her take the rap for now. She's OK with that.

I thought it might clear itself up but it's July and still nothing.

Questions:

What's the best option? Dig it up, replace the topsoil and seed it? How deep? How about transplanting shovels of scooped up grass from the back yard?
