I was given a small clay pot last week from my daughter’s sitter with a few flowers sprouts in it. I’m not sure yet what they are. I noticed yesterday there is a white fuzz growing along the rim of the pot, which is actually causing small pieces to break off and makes me wonder if it’s actually growing from inside. I’m guessing it is some sort of mold, but haven’t been able to find anything like this on the Internet. Anyone have a clue what this is, or if it’s harmful? I don’t see any signs of mold on the sprouts or soil, or anywhere else on the pot.
