Question
I live in Dothan, Alabama and my question is why do I have white mushrooms popping up everywhere in my yard and my neighbors do not?  What is causing this?

Answer
I'll tell you something about Mushrooms.  Think of them as Flowers, Angelia.

That's right.  Fungus Flowers.  They grow from spores.  They need certain things to grow.  When they 'bloom', and you see those Mushroom Caps on your Lawn, it tells you there is a Fungus down there.

It's not the Mushrooms that are the problem.  It's the Fungus. Way down under.  Fungi are practically the ONLY microbes -- yes, these are microbes -- they are almost the ONLY ones that have the equipment to rot wood.  Wood is made of Lignin.  Bacteria CANNOT break down Lignin.  But a Fungus can.  You have Lignin down there underground.  There's Fungi down there breaking it down.  And with your Fungus-friendly watering program, you are growing Mushrooms that are blooming in your Grass.

Let me tell you the good news quickly here:  Mushrooms are ugly, but temporary, and not harmful to your Grass.

In fact, whatever wood is down there being decomposed is sucking up tons of Nitrogen, away from your Grass, to do the decomposing.  This is an exercise that needs Nitrogen to happen.

We'll worry about those later.

My next guess is that your pH is probably low.  A soil test would give you a lot of great information, but if you don't want to be bothered with one of those, get out the Pelletized Lime.  Pelletized will solve the problem on the surface and bit by bit will penetrate the top inch layer of your Lawn.  It will also make life uncomfortable for the Fungi.  While your other Good Fungi are recovering.  Which they will.  If you don't keep wiping them out.

I am trying hard not to get to complicated here.  Please let me know if I have failed at that.  It is hard to make a point without explaining to educated people the legitimate facts behind the point.  But it is easy to get too complicated and confuse people with the facts.

If you water watering daily, please stop.  Mushrooms and Fungi thrive on moisture and darkness.  You can pick up some PELLETIZED LIME at the garden center between BBQs next weekend.  Rake up those Mushrooms every morning, to keep it pretty.

Any trees way down there that you had removed a few years ago?  Have you been putting down any wood chips for some reason on your soil?  Are tree twigs landing on your Lawn, ending up underground, waiting for a hungry Fungus looking for Lignin to move into?  That would explain your Mushrooms.

Mushrooms usually need a higher level of moisture.  Is your Lawn shadier and/or wetter than your neighboring Lawns?  Do what you need to to keep your Lawn happy and healthy.  Rake the Mushrooms up daily.  Eventually, they will 'bloom' themselves out of existence.  Maybe your neighbors are next!
