compost with red worms

As long as you have a place they can get plenty of air, a worm composting bin doesn’t smell unpleasant and doesn’t take up much space. I’ve got my worm bin out by the garden now, but come winter I may bring it in to the basement (even in Seattle Washington we get some freezing weather). Or I may just pile hay bales around it.

its too cold for them to thrive in ottawa. it may be a seasonal goal.

Is there anything more environmentally friendly?
