I live in Arlington, TX and laid new St Augustine down this summer. I have had great results and this seems to be the first problem??? I have noticed with the grass so far. We have had warm and cool weather changing alot lately. I showed to my father who used to do irrigation and he thought it was a fungus and recommended I put down a fungus control product. I put down Scotts Lawn Fungus Control two days ago, but really thought it would be a great idea to post some pics on here and get some ideas of what you all think about the yard what your thoughts might be...I am open to ideas...thanks ahead of time. Is this a fungus or appear to be a fungus...seems kind of wierd to just brown up in some patches around the yard. This is the corner on a corner lot. Thanks!
