In cold climates the compost pile will go dormant in the winter without special consideration. This is fine. Continue to add kitchen wastes to the pile throughout the cold months and it will start up again when the weather warms.
If you want to keep composting year round be sure to place the compost pile in a sunny area to take full advantage of the sun’s warmth. Place straw bales around the sides for added insulation and cover the top with a tarp.
