Question
I live in California and planted sod in the yard.
I tilled up the ground first and hauled in top soil the laid down the sod and watered daily for two weeks. The grass came out nice, but now I have an abbundance of small mushrooms growing in the grass and noticed patches of it are turning brown. The mushrooms seem to disappear in the daytime, but are all over before the sun comes up in the morning. How do I get rid of these mushrooms?
Thanks for your help Rod  

Answer
Hi Rod;
You've got fungus.
It could be because of dampness, if you have had a lot of rain and not much sun. or it could be from a root under the soil that is rotted, and causing this.
That is not likely if the muchrooms are all over the lawn.
some articultural corn gluten will take care of that, or yu could just disolve baking soda in water and spray it on the lawn, saturating it well.
Sounds like you have very damp nights, and hot days.
Heat kills out the fungii, unless it is very humid heat.
The patches that are turning brown sound like brown patch fungus. especially in light of the mushrooms growing there.
The corn gluten or baking soda will take care of that too.
You can use yellow cornmeal if you can't find the gluten.
I don't know what the white doesn't work, but what i read stressed yellow cornmeal.
