It appears from trying to apply what little brain power I have to some of the info available on the web, that there is little one can do(without extreme measure) to 'kill' a fairy ring. I have one that encircles part of my lawn conatining roots from a Silverleaf Maple removed 2 years ago (likely the food source for the fungus) and a 1.5 year old installation of a 30 gallon container sized lacebark Elm. The Elm is doing quite well but lawn grass in the area is practically exterminated. Any suggestions?
thanx
