Getting Rid of Moss in Your Lawn?

Thanks for your non-metalic solution. I am not in Seattle, but have moss in my back garden too. I applied it once. but it didn't kill my moss. At least it didn't kill grass as lawn sand or ferrous sulfate did to my lawn. I think I didn't apply enough. How big is the small area you mentioned about? If my lawn is about 250m2 (about 100sqft), how many gallons of the solution should I use?

Thanks.
