I've got mushrooms growing around, and partly in my flower garden. Is there some kind of treatment I can use to prevent them from coming back? When they come up, I go out and pluck them all out. I keep hoping that getting rid of the caps will stop the spores from spreading, but there's obviously more to it than that. I can't really remove all the soil, because they're mostly in the grass. I used to have a tree there. Funny, they never came up for a year or so, when there was a big pile of chips and dirt there. Here's a pic of the shrooms growing up from underground, and pushing the soil up. Those are crocuses that are sticking out of the big clumps.
