Hi! I have a bokashi soil factory using old potting soil. I planted my flowers using my bokashi soil and then put the lid on my factory for later use. After a couple of weeks I opened the tub and noticed not only the white mold, but a green mold on a piece of fermented food sticking out of the top of the soil. The green mold reminded me of the kind of mold that grows on a molding orange. Is the compost safe to use or should I mix it and wait?
A small amount of green mold is not a problem. Make sure to chop it up and mix it in thoroughly. If there is plenty of white mold, that shows that the good bokashi microbes are thriving and these will soon take control of the small rotten area. Your compost is safe to use.
Make sure to add a generous few inches of soil on top of your soil factory in the future to prevent this happening.
