    I have a lawn that is drying out no matter how much water I give it.
    I gave it some Miracle Grow lawn food about four months ago because it was about time to fertilize it. About a week after the fertilzing the grass looked wonderful and it grew like crazy.
    About 2 months later, it started to look like it was drying out again, I gave it Miracle Grow lawn food again and took a iron rake and raked up the thatch in the lawn thinking that the thatch was getting too thick and the water wasn't getting to the roots.
    The lawn was put down as sod. It looked wonderful for the past 3 to 4 years now and its not doing well.
    Do I need lime or something like that? I need to get my beautiful lawn back.
    There is also a patch that turned brown and the grass died and the patch got bigger and bigger until now which is about 2 1/2 feet around and going. Is that a disease that is causing that?

    Any input would be greatly appreciated.

    You may have a fungus problem , as far a PH and adding lime test the lawn first to make sure it needs lime. Only water during morning so the lawn has time to dry out before evening, never water in the evening.

    Try calling a company in your area to get an idea, looks like fungus, Zoysia doesn't like a lot of fertilizer. Good luck

    Too much feed. Got to get them roots growning first before you feed.

    Based upon where you are, it's likely a fungus issue.

    Stop feeding it !
    Feeding turf that is being affected by (certain) turf fungi can worsen the problem !

    Get the problem diagnosed and treated.
    Then reseed / re-sod / 're-plug', or whatever, and learn from the experience, and hopefully have the right chemicals on hand, so you'll know what to do as a preventive measure next time.

    If it is possible, I think I would pull a sample and send it to the University of Florida with the sample form attached below.
    I have found nematodes to be a problem on the handful of zoysia lawns I have seen in our area.
    The damage is very similar looking.

    Do you have a pet? I think you have something soil related going on. If it is a disease, it must have been there for a long time, because you are down to bare dirt. Zoysia patch diseases are very common, but that does not look like Largepatch to me. Generally you will see a reddish ring where the active disease is. What you have looks more like wear or general decline.

    its not a watering issue.. zyoisas lawns require little or no water once established.. You either have a bug or a fungus..
    Up here we experience this type of grass growing so thick that it creates a matt that does not allow it to get the proper Oxygen and it promotes fungus and disease and it .. for lack of a better word chokes itself out...
    However this usually happens with people who have had this grass for ten years or so..

    I would aerate it like crazy... put down some diazinon or dialox spelling??
    If it doesnt come back the fungus may have already gotten it.
