    St. Augustine Problem

    Dry Weather Lately, However healthy grass surounding area seems plenty watered.

    Does not seem to be the common circular brown patch that occurs in wet areas.

    "Bald" green & healthy looking runners exist amongst a dry hay type thatch of the dry, dead, and fallen off leaves.
    So, though the hay thatch is dry and crisp, the runners that remain are green and juicy, there are simply no leaves on them.

    Grass Fed quarterly, Shows no sign of under-water. Yet no sign over the over water that usually causes brown patch.

    Do you have photos? Close up and far away is best.

    We are dealing with this here in n Fl right now. It has been a mild winter for us and the lawns were nice and green through end of February. But, the last week has produced some below freezing temps and frost which has browned out the more exposed areas of lawns. As long as the stolons are still green and juicy, i can confidently tell my clients that the lawn is not dead and it will just have to flush out new growth with application of fertilizer.
    If there is excessive foot traffic over the brown foliage, it will quickly expose the stolons.

    We dealt with a lot of Brown Patch this fall also because it stayed so mild and humid through January. The soils could not dry out from a wet summer.

    Go out to that area and pull up some Stolons [runners]. Try and pull several, one at a time, with some length to them. If you pull them and they come out easily without any roots there is a good chance you had some pretty good Grub damage last Fall. If you pull them up and they transition from healthy to dead and the roots go from healthy to hard and dark then you probably have Take All.

    Thanks for the tips yall! I'll spare you the boring info, but im glad of your answers.

    The grass in general is extremely tough to uproot, its really clamping the soil. And to think....people say St.augustine doesnt like clay :)


    How is everything is gainesville?
