I had the realtor come up this last weekend, and she noticed
mushrooms in my lawn (id never noticed them before), she tells me
thats a sign of healthy soil? If it is I dont know how it became
healthy, I dont hardly fertilize my lawn, and I do nothing special to
it, except douse it with water when I can to try and keep as much of
it green as possible.

But is it really a sign of healthy soil? Or is it an old wives tale?

It's an old Realtor's tale.
