brown circles on lawn
Can someone help me identify what is going on with my front lawn. We have perfect brown circles that are about 6-10" in diameter spreading all over it. In some places they are connected so it looks pretty bad.
We are trying to shift to organic this summer but haven't yet. We did put down a Lesco fertilizer the second week in May but otherwise nothing. The side of the lawn we used the Lesco with crabgrass preventer in it does not look bad at all. That area is also pretty riddled with weeds of various kinds and will be the focus of upcoming projects. These patches look like they are nearly dead. This problem started a week or so ago. We have had a pretty wet spring so I don't think it can be lack of water but we do not have an irrigation system. I have tried to search and thought it may be "brown patch" but does that come in circles. Oh, the area gets full sun from about 10 or 11 on. I'd love help with a diagnosis and how to treat it, please. Thank you!
