If the fairy ring consists only of mushrooms or puffballs, with no stimulated grass growth, simply rake off and dispose of these fungal fruiting structures. If handling the mushrooms, wash your hands when done.

As serious injury to the turf does not occur often with fairy rings, the most practical method of dealing with them in lawns is through a cosmetic approach. Disguise the symptoms by providing adequate water deep into the root zone, and by applying moderate rates of fertilizers. This will increase the vigor of the surrounding grass to the level more like that of the grass in the fairy ring. Excessive application of water or fertilzer should be avoided as either may contribute to other turf diseases or stimulate fairy ring development. More frequent mowing may make the difference in height between grass of the fairy ring and adjacent grass less conspicuous.

In rare cases where complete eradication of a fairy ring is necessary, the sod and underlying soil in a band 12-15 inches in front of and in back of the ring can be removed to a depth of 8-10 inches, depending on the extent of the development of the ring. The resulting hole should be replaced with clean, preferably sterilized, topsoil or soil mix. New sod or seed can then be established where the fairy ring was removed. Soil fumigants are sometimes effective for eliminating fairy rings, but this treatment must only be done by a licensed pest control applicator who is qualified to safely use toxic fumigants.
