How To Identify Fairy Ring
Fairy Ring develop in areas that were previously forested or where stumps or other organic material was used as fill. It develops during the spring and early summer as circles of dark-green, fast growing grass. The reason a circle of green grass grows is because of the chemicals produced by the fungus. A clear sign that you have fairy ring is when mushrooms start to grow in the dark green grass after rain. The grass will normally die which will cause a yellow circle to appear in your grass.
