What is it?

  • It is one of the most annoying problems in lawns.
  • Fairy Ring first appears as a circle of dark green, lush, fast growing grass. A brown dead ring of grass surrounds the lush area.
  • Rings or crescents commonly vary from 3’ - 49’ (1 to 15 m).

  • The fungus can show various symptoms such as:
    • circular stunted or dead grass zones

Fairy Ring in a Lawn


  • The turf can be removed and the underlying soil can be replaced. This method is very expensive, difficult and not always effective due to re-infestation.
  • A more practical method for controlling Fairy Ring is to poke a garden fork into the ring and water the areas heavily. The water floods the disease and carries the Fairy Ring spores away from the grass plants.
  • Fairy Rings are less noticeable in a well maintained lawn.
