    Im trying to figure out what is causing this yard to die. Over the last 3 years the st augustine is slowly dying out and weeds are taking over. it started out as 2 circles, 1 about 4 feet and the other about 10. Now its half the yard. Before the homeowner didnt care but now she is wanting to fix the problem and im not sure where to start. I have fertilized the yard twice this year with Bonus s. its in the mid 90s here and when it rains the grass looks great but without water in 2 days it starts to wilt. If anyone could look at these pics and help identify the problem that would be great.

    Ask the owner if there used to be a tree there. The soil could be highly acidic, have a PH test done on the underlying soil to find out what the soil is doing.

    Looks fungal. Have you done ANY fungicides over the years? Soil harbors fungi; it is not active during the cooler and dryer times of the year. You might get on it with Ensignia at the curative application and then again in 14 days. As mentioned, a soil test to establish where we are as to pH and micros would really help. I would change fertilizers to a liquid diet. Also, take a couple of photographs that are close up and if possible include some root photos and extremely close up of the blades. The genius may weigh in with some tips

    What time of year did it start 3 seasons ago? It could be fungal and is the most logical problem. Start with measuring the patches and remeasure every visit to figure out if you are making any progress.

    It was already ther when i started mowing the lawn its just continued to get worse. I am not licensed to put out fertilizer but agreed to put it out(at no charge) if she bought it. No other chemicals have been applied to my knowledge.I will need to get someone licensed to come out for any further treatment. Here are some close up pics.

    More than likely Necrotic Ring Fungus. Although, the overall color is more snow mold looking, but thinking you're too south for that. Let us know how your company deals with this. I still maintain that Ensignia and surfactant at the curative rate every 14 days.

    Thanks for all the replies and advice. Im going to get a soil sample next week and see what that says. After that i will suggest a fungal treatment and try and find someone to hook her up with. Thanks again. You all have been a big help and I will post what I find.
