I have what supposedly is a fairy ring which no matter what i do including
digging it out completely as per RHS and re turfing it reappears
..........however the recent rains have made it worse and now 2 more sections
6 ft and 12 ft away have appeared

We laid the lawn 32 years ago and its always scarified, and treated with
both spring and autumn feed

I am utterly desperate over the appearance of more bare questionable patches
with recent rains .......have only had 3 small mushrooms appear at one end
though
