|Red Wigglers can withstand freezing temperatures, but they do need a warm core to keep active to break down your refuse. A good pile of kitchen waste needs to be present over-winter, to keep these "munchers" going.
|Don't forget to add a brown layer every once in a while, to help enhance the final product.
