I have read on various worm-forums that one should not put charcoal ash in the bin, why exactly is this?
The other day my fiance put quite a lot of charcoal ash in our worm bin by mistake. When I discovered it, after yelling at him rather extensively, I managed to get most of it out, though I didn't want to sacrifice too much compost so had to leave some in. I then covered it with potting soil and damp newspaper and the next day added chopped spinach as I heard that the nitrogen from leafy green plants would help to stabilise the bin again. When I was taking the ash out I could see the worms moving about in the compost just below the layer of ash, I was hoping that would be a good sign that they weren't too bothered by it? And the last time I checked the worms seemed to be happily moving about in the layer that had some charcoal ash in it, so I'm hoping that they are ok.
Any advice about what to do? And why not to use charcoal ash?
