Never underestimate WD40.

I once had a large fairy ring in the front garden, about 12' across. I
sprayed the heads with WD40, and then again after about a week.

In the autumn they made a reappearance, and got the same treatment.
The following spring the survivors got another dose, and that was it.
They disappeared never to return.

It was a*lot* easier than digging up the soil, getting rid of it, and
refilling the hole and replanting.

Never felt the need to kill fairy rings as they don't seem to do any harm.
