squidgygoanna Posted July 22, 2017 I moved some of my sensitive plants into an indoor greenhouse for the winter and they've all started growing this white fuzzy mold on the pots, the top of the soil and on some of the stems of the plants themselves. So far I've tried some Cupric Hydroxide (Kocide Blue Xtra) fungicide, which didn't seem to do anything. I then removed each plant individually, wiped off the growth with some isopropyl alcohol, and removed the top layer of soil and replaced it with fresh, dry soil with some cinnamon mixed through. The top layer of soil seems to now be resistant to the growth, however it's reappearing on the pots and some of the plants stems. The plants are under T5 lighting, and I added a fan to try and circulate the air a bit more.and dry things out. Can anyone help? I also have 3% Hydrogen Peroxide, Vinegar, and Baking Soda on hand (which I've heard can be used to make a DIY fungicide) Share this post Link to post Share on other sites
