There are mushrooms and other fungus growing on my mint seedlings. I water them about once a week and have them in a south window but I don't know why it is growing on them. I was going to pull the mushrooms out and spray some of my Cleary 3336 on it. The thing is when they get big enough I will be using them for tea and other things. So will it be ok to use the fungicide or will it kill me?
