Hi, Jennifer: Just to be on the safe side, sure, go ahead and remove the affected soil, then proceed as usual. Mold is everywhere, though, and usually doesn't pose a problem in soil, as it will dissipate once its growing conditions (organic food, a lot of moisture) deteriorate. Mold on plants is another matter, as you recognize, as is nonwhite mold. Thanks for asking!
