Question
Hello, Thanks for your help.  Just to add a little bit from the last time I wrote,  Here in the great state of Wisconsin (ha ha)  It has been really rainy.  Before I had some mushrooms  but now (wow!!!)  My yard is full of the disgusting things.  Is this a confirmation of the fungus?  If so how do I treat it?  Is it something I can do or is it something I need to hire a professional for? The light green rings are still there.  The mushrooms are not in the circles and are of all different kinds and sizes.

Question -
HELP!!!!!  My lawn (my baby) has developed light green circles in it. The light green cicles look healthy but are almost perfect cicles and stand out.  I live in Franklin WI.  They seem to devolope after it was dry out.  I was watering durring the dry weather.  please help.  I hope I gave you enough information, if i didn't please e-mail me  thanks Mark Hernon

Answer -
Mark, my friend, Wisconsin is a far, far ways from Long Island New Yawk, and your climate and grass may be different enough from our East Coast lawns that I have to say this is only guesswork for me.

So please keep that in mind as you read.

I take it there are no mushrooms/toadstools in those lovely circles you are cultivating?  Or you would have mentioned that, correct?  Please just confirm.

I am a bit confused about what kind of moisture your grass was getting.  You mentioned the weather was dry.  But you also mentioned watering the grass.  Makes perfect sense - exactly what a responsible homeowner would do when the weather is dry, you water the grass.

But did you water the grass A LOT?  As in, did it dry out between waterings?  Or did you love it so much, you just could not help but give it too much of a good thing (water)?

Because too much of a good thing at this stage of the game, when the air is getting cool, and the nights are getting longer, and the water just keeps on coming, is the perfect way to enter into the grass fungus business.

Now, there might be a good explanation for green circles.  I understand some people in the West are known to carve circles in the fields at night as a joke, suggesting these are aliens from another planet - or it could be you just fertilized without realizing it in a circular fashion, hard to imagine how you would manage to do that... Or it could be fungus amongus.

Just clarify for me the moisture situation.  And if you know what the name of your grass is, that would of course help.  And finally, I have a feeling you have been putting Weed and Feed/Grubkiller/WeedBGone etc on the grass, perhaps you don't know these innocent looking powders destroy beneficial stuff in the soil that protects your grass from bad things like fungus?

rsvp - we have lots to talk about!

Answer
Mark, I am so glad you wrote - before calling Professionals - because these Professionals are almost always responsible for creating the problems you described, and then charging obscene fees for correcting them, then explaining why it isn't their fault for not fixing it because your lawn has some mysterious rare soil disease... read back on some of these AllExpert questions and you'll see what those Professionals can do to a HEALTHY lawn, you won't call them in for a problem.  Well, that's my humble opinion, but I think you can do this yourself anyway.  For free.

"Disgusting Things" is not really a good description of your problem, Mark.  I enjoy reading your question but if I am going to help you, would you be able to describe whatyou see?  Is it slimy?  Powdery?  slippery?  black?  Yellow?  Red?  White?  Blue?  etc.

The Mushrooms are a moisture situation.  Go out and rake in the morning and you'll get rid of them until they get rid of themselves.  By raking, every morning, until it gets too cold for them, you eliminate any possibility that a child or curious pet will pick one and taste it.  Plus they are not very pretty.

"Lots of rain" in these temperatures at this time of year is a recipe for numerous kinds of Fungus.  

If treat your lawn with things that upset the Balance of Nature in your soil, you wipe out the Fungus controls.

Fungus is like Mildew and Mold in the house.

If you go into your living room, you probably don't have any Mildew problem, right?

And why is that?

Is it because you spray diligently with Mildew Killer By Scotts?

Of course not!

You don't have Mildew in the living room because Mildew doesn't grow in the living room.  But we both know it's in the air, all the time, ready to rock and roll.

But take a wet towel after a shower and leave it on the floor for 4 or 5 days, and what do you have?  

Mildew!

And to get rid of it, you don't go out and buy Scotts Mildew Search-And-Destroy.  You hang up the towel.  Mildew problem solved.

Same thing goes for grass.

There are dozens and dozens of Fungus species RIGHT NOW, sitting in my lawn, your lawn, the lawn down the block, all over the place everywhere.  But the world is not being attacked by Fungus.  Right?

Why not?

Several reasons.  The number one reason being that Fungus needs certain temperatures to grow, lots of moisture to grow, darkness to grow, and freedom from competitors and predators.  There are natural controls out there that destroy Fungi.  Unless you wipe them out.  Which you do with herbicides.

But if you stop JUST ONE of those other things, NO FUNGUS can survive.  It will just lie dormant.

So if you dry out the soil, the Fungus will die.

If you warm up, or cool off, the soil, the Fungus will die.

If it's sunny 24 hours a day, the Fungus will die.

It's simple.

It sounds like you have a Fungus problem.  We don't know which one, and if you want, we can go into the problem in detail and identify which Fungus or Fungi you have.  But we can stop it from spreading by drying out your soil AND not putting any more weed killer on the grass.

By the way, this is why people who don't take are of their grass NEVER have a Fungus problem.  They leave the weed killer on the shelf in the garage or they don't buy it at all.  They don't kill the natural controls that keep Fungus, and many other problems, from taking over the world.

And people who love their lawns and love to care for their lawns - they're the ones with the Fungus.  Because they think putting down weed killer and other things is the best way to take care of their lawn.  And it is not a good thing to do.  EVER.

You really have to cut the moisture.  If it rains, you can't do anything about that.  But I don't think you have to worry about it too long.  Just stop watering the grass.  Rake the mushrooms.  This will work itself out.  Be patient.  Write me back if you have any more questions about this or need clarification.  These are both common problems.
