  • Clean thoroughly with soapy water. Then you could use very hot water 65 degrees centigrade 10 minutes. Or solarize, leave in the sun for a day or two (need to expose all surfaces which may not be so easy). The UV light kills bugs.
    What I do though is add worm castings. They compete with and "smother" the pathogens, in this case mold. If you have more time you could grow a "crop" of worms in the pot or embed the pot in a worm farm if suitable ie big enough worm farm for the pot!
    Chlorine based bleaches will kill off mold but then so does vinegar but may leave the spores.
    • Thanks Harry! Don't have any worms yet but maybe in the future.
