I see you recommend iron sulfate to kill moss. I see brands out there but not sure which is correct one to purchase. Can you provide me amount of iron sulfate required per 1000 sq ft. I know you can not recommend brands but if you also know several brands that contain that I would appreciate.

I would just use the amount recommended on the package. Do keep in mind that even if the moss is killed, you would need to rake or dig it up. It would probably just be easier to rake the moss up when it is green then to kill it and rake it up when it is brown.
