How may Fairy Ring appear in turf grass?

Fairy Ring typically presents itself in turf grass as either a ring of mushrooms or a dark-green ring in the grass. This phenomenon occurs as a result of a fungal growth beneath the surface of the soil, with the mycelium (the vegetative part of the fungus) spreading outward from a central point. As this happens, the nutrients in the soil can become depleted, causing the grass just outside the fungal growth to appear darker and more lush. This creates the characteristic ring shape, often accompanied by visible mushrooms that emerge at certain times.

The presence of a dark-green ring and mushrooms is indicative of the biological activity associated with the fungus, which alters the soil and nutrient availability around it. Other symptoms, such as yellow blades, bare soil patches, or wilted grass, do not accurately represent the typical fairy ring phenomenon, as these issues can arise from other stresses or diseases unrelated to the specific characteristics of fairy rings. Understanding these visual signs is crucial for proper identification and subsequent management of turf grass conditions.
