Correspondingly, why are mushrooms growing in my lawn?
If your lawn's soil is healthy with good organic matter, Mushrooms will grow in your lawn as these conditions are perfect for fungi. They love damp and carbon rich soil, so usually after an extended period of rain and cool weather with decaying organic matter in the soil you may see a variety of fungi growing.
In this manner, how do you kill mushrooms without killing grass?
Mushrooms can also grow indoors and should be immediately plucked. A simple solution of a few drops of dish soap to a pint of water will kill off mushrooms. Stick holes in the top of the indoor potted plants' soil and spray the solution onto the mushroom, making sure not to spray the plant stems or leaves.
Mushrooms are an indication that your yard has a lot of organic material in the soil. Mushrooms help break down that organic material and make your soil more productive. If your shade and drainage aren't real problems, you can always just knock the offending mushrooms over and wait for the sun to come out.
