So I was a bad gardener and kept my dead plant in a pot for over a year and a half.... I just cleaned it out tonight lol My question is, is it ruined? There are two pots. One has a little bit of green tint at top were the soil ended, it may be mold. If it isnt mold do you know what it is? Should I try to scrub it out? Is it harmful? The other one is clean except for stuck on dirt. Thanks!
