I’ve had mold growing on the surface of my pots for a long while. I kept removing the soil from the surface but that didn’t help. So I went and bought expensive fancy soil!! I took out the plants from the old soil and tried to clear them ip as much as I could and replanted them in brand new pots with the new soil. But bingo! There’s mold growing again.
These are citrus plants that I’ve grown from seeds and I use citrus feed when I water them. I live in a reasonably cold and very damp climate and I don’t water them too often (once a month or so?) they’re indoors behind south facing windows. Is there something I could spray onto the soil to kill the mold?
I searched thoroughly before posting this and did read the relevant posts which mostly suggest preventing mold. However I’m wondering if there’s any anti fungal spray I could use on soil, ideally home made.
Oh, by the way, could it be due to the plastic planters? I notice the other plants taken out from the same old planters and planted in clay pots don’t have any fungus. Maybe the plastic isn’t breathable? But for now I’d like to kill the mold if it’s an option as I don’t have the time to buy other pots and replant again.
