|I recently noticed that there was some gray mold growing on top of my Dracaena's soil, and decided that it could be 'cause I water it too much. So, after watering I picked up the pot to empty the standing water in tray underneath it. When I lifted it, to my surprise I found a white growth all over bottom of pot and in the tray! Looks like little balls of fungus. Smells like fungus too and it didn't move, so I knew it couldn't be a pest. So, I quickly took the plant out of the pot, got rid of much of soil and washed pot with hot water to hopefully kill the fungus. And repotted with fresh soil. What could this be, will it harm my plant, and do you think it will come back?
