    Hi Everyone,

    New to the site and, and what a great resource it is! I have some circular spots on my lawn that the grass is not growing correctly like the rest of my lawn. The area is between 2 hoses and gets less sun than the rest of the lawn. After the first spring fertilizing application the rest of my lawn looks great except this area. The circular spots are about 10"-12" in diameter and cover about a 7-8 square foot area. Grubs? Insects? Any Suggestions?:confused:

    Take some pics, but it sounds like you may have Necrotic ring spot, a nasty fungus.

    I will get some pics tonight. I know my neighbor doesn't take care of there lawn like i do, and it is not as healthy, and it may have migrated over. Thanks for the help!

    I've seen more ring spot around here so far this spring than I've seen in a very long time.
    I guess it's because of the type of spring we're having.

    The problem could be simply fairy ring, too.

    Just click on the website on my signature line, that will take you to our website, hit the "contact us" and send away, pics are easy to post here to, just click on the paperclip and you can browse out to where ever you have pics on your computer. If the rings are 10-12 inches in overlapping patterns, I would suspect necrotic ring spot. Especially if the rings are depressed, feel them with your hand. If you just have one or two rings in the lawn, it very well may be fairy ring.

    Was there a treee or shrub planted in those spots before?
    Could there possible be some kind of wood under the turf, new wood or rotting roots will pull lots of nutrients out of the surrounding soil.
