St Augustine Grass - damage - help
I have a 2 year old St Augustine grass lawn. Through most of the summer it looked pretty good. However, over the last few weeks - areas are turning yellow (they are very random with no pattern) and some are have even died out. I have fertilized twice this year with milogranite and have applied corn meal as a fungicide. I have not been watering this year - but we have had plenty of rain, so I donÂt believe I need to. I have looked for gray spot and brown patch - but it doesn't appear to be that (I had that last year). I did the soap water test for cinch bugs and didnÂt see any (just hundreds of worms). I am looking for help trying to figure out what is causing the lawn to die, so I can figure out how to treat it. I was wondering if I should treat with more cornmeal - just in case it is a fungus - can I put on too much cornmeal. I appreciate any assistance you can provide.
