Roof Cleaning Best Practices

Very informative. Thanks for that!

I know old farmers use it or at least use to here in the midwest but I think that was going off the outdated info about it lowering soil ph. Gypsum is part of my lawn maintenance regime as per my soil test recommendations to help with the “tightness”. I just started the gypsum this spring so can’t say what any overall effects are. I’m sure it’s nothing I’ll notice but assume it will help the overall look and health of the lawn. It’s a newer lawn just seeded last fall after killing off the old.
