Sprinkle Used Coffee Grounds Around Plants

If coffee grounds are already moldy can they still be used outside? What can be added to the grinds so they don't spread the mold?

Excellent question. You could do either or both. The powdery or gray mold is not going to hurt anything in the soil or your compost. Good luck. (04/18/2010)
