    Sounds like fairy ring, it really can get going after rain and a shot of warmth.

    It's caused by fungii in the soil breaking down organic matter such as a piece of old tree root or wood buried in grading. The fungus rarely kills grass but does look unsightly. You can try to fertilize the lawn to try and mask the apperance.

    Maybe I misunderstood the question when she said BRIGHT green cicles...that are growing. Are they a darker color than your lawn? Is THAT what you mean? One key to them being Ferry rings, is that they are never a closed loop. There is always an opening. Let us know....:)

    Not true, for a picture of contiguious ferry ring, see "Diseases of Turfgrass by Houstan B. Couch, 3rd addition" plate 29 A-C.

    Want to know if it's a true fairy ring? Go take some core samples. You'll know right away if there's white stuff in the core. Also, send it off for testing seperate from your other cores.

    YES YOU PROBABLY HAVE FAIRY RINGS. THEY ARE VERTUALLY IMPOSSIBLE TO GET RID OF. THEY WILL EVENTUALLY GROW OUT OF YOUR LAWN AND BECOME SEEN BY AIRPLANES ALIKE.:angel:

    Also, a characteristic of fairy ring is the presence of mushrooms in the effected area during rainy periods
