In the coat closet of my tiny one-bedroom apartment, next to a suitcase and my winter boots, is my blue plastic worm bin. I have been composting with worms for about a year, and cannot imagine going back.
I am still in awe of the efficiency with which my worms work, and I'm always amazed to open the bin and find almost no evidence of the food scraps and coffee grounds I fed them only a week earlier. I am not an expert in biology, agronomy, or even vermiculture, but right in my closet, I have managed to maintain a thriving little ecosystem, and produce a continuous supply of rich, dark compost.
