Q.worm bin dirt
Last summer, my worm bin began to smell and I discovered that all the worms had suddenly died. I left the bin so its contents would decompose, and now more than a year later, I opened it to see what looks like good dirt but with some white, perhaps moldy looking stuff, atop some of the dirt. I wonder if this can be dangerous in any way and can I still utilize the dirt if I skim off the white stuff. Many thanks for your help!
All the best,
Janice
Mold is part of the process, you should have no issues with your compost.
