How to get rid of dry, powdery mildew looking growth in my lawn?
Trying to de-weed and revive my lawn following the "junk" blown in with a hurricane, I'm gradually getting rid of heavy weeds and pasture grass. There are sections around the yard that have a dry, powdery growth on the blades of St. Augustine. It looks almost smutty but it is not smut grass. Please help me identify the growth and give suggestions on how to get rid of the unwanted stuff.
