Special watering techniques can also be helpful. Using a tree root watering wand or punch holes in the soil surface and use a wetting agent to help distribute water through the infected area. The goal of this approach is to stimulate micro-organism populations that are antagonistic or parasitic to the fairy ring fungus. This method also helps overcome the water repellent nature of the fairy ring. Other methods of eradication include soil fumigation, soil replacement, and soil mixing.
Fumigation is an expensive process and involves the use of highly toxic materials.
For these reasons, it is recommended that only a licensed professional conduct the process. Soil mixing and cultivation have also proved effective in getting rid of the fungus. Turf should be removed from the site and the soil tilled or cultivated repeatedly in different directions, using a rototiller if possible. Simply digging or plowing the soil is not considered adequate, the area should be thoroughly soaked to encourage microbial antagonism. Keep the soil bare for a month or two, perhaps an entire winter if possible.
