This is not great news....We have mushrooms ALL over our backyard...and its the only place I can let the girls out...I noticed acouple of them last week and had the hubby dig them out but when I was out there yesterday they have taken over the back yard...big brown ones...Anyone know if there is something you can put on your lawns to get rid of them...although I have over an acre to take care of.....without poisoning the girls? I really can't believe how many I have...last year we didn't have any...whats up?
