For our St. Augustineturf, we de-thatched and aerated today (big-time), followed-up by cow manure compost. After applying so much bifenthrin to thwart sod webworms a month ago, we needed to get some life back in the soil - hence cow manure compost.

Wanted to ask - when I walk the dogs I noticed a lot of lawns have either of the following 2 problems: large spots with mostly thatch and green shoots, or the entire lawn a mixture of green, yellow, and dead grass blades. Are yellow blades a root problem or iron problem?
