Fairy Rings

 Hello, neihbours got major fairy rings. Got a couple just starting to show
on my front yard.

I heard that plug aerating can help.

Anyone heard of this?

Thanks in advance, Dave

 
It can't hurt, but the only real cure is to remove whatever
is rotting from your subsoil. Tree stumps and home building
debris are the most common culprits for fairy ring.

 Just a question
If you aerate will you spread the disease to other parts of the lawn or are
we talking just aerating the effected areas
thanks

 No, you won't spread it. Aerate the whole lawn at least once
if you're paying for a rental.

The rings won't change much from your aeration job, but the whole
lawn will thank you for it.

The rings will subside a bit when the weather cools off, don't be
fooled into thinking the aeration helped.

btw...we don't aerate untill Septemer, here in Ohio.

 Fairy rings are formed from fungal mycellial webs (underground) which are
breaking down something under the ground.  You could lift the affected lawn
sodding (including several feet in front of the spreading ring) and remove
the debris.  Or, you could just let the ring run its course.  Unless the
lawn above it is dying (then it's probably brown spot -- treat with a
fungicide), don't worry about it. It won't hurt anything.
