How do I know if I actually have worm castings?
Well I have had my worm bin for about a month now and I would like to harvest a little for a basil plant I recently started. But the thing is that I do not know what is worm castings and what is just the thin layer of compost I put in the bin to duplicate there environment. How do you distinguish between worm castings and regular soil? They are all active and been reproducing like crazy so I must be doing something right.
