perhaps you are doing too much stuff to the lawn. maybe if you mow it and ignore it, (have some gin) it will be happier. i’m no expert but my dad worked at a golf course for 45yrs and i picked up a few things. sometimes, grass is better if you just leave it alone and stop fooling around trying to have a “perfect” lawn. fire the fertilizers, put down the hose, and have a drink. it may work, it may not but it will be more relaxing than worrying about a bunch of stuff that can generally take care of itself. although i must say i have seen diseased greens look like that too.
I’m wondering if its some sort of fungus. Honestly, this year, I’ve done much less than I’ve ever done. And it looks much worse. The tru green guy only comes every other month too.
Our lawn may not look as pretty as some of the neighbors, but we're just as happy.
