- Taking your compost inside with an indoor composter.
- Insulating your existing compost bin from the elements.
- Insulate your bin with straw or cardboard. Stack hay bales around your bin or strap several layers or cardboard around the perimeter to provide insulation and prevent freezing.
- Cover with plastic (with holes in it) to keep heat and moisture in.
- Put your compost bin in a pit and use the earth as an insulator. By digging a hole a couple feet deep and either using as a compost bin or placing your bin inside, it will stay warmer.
One great thing about the winter months is that you can turn your vegetable garden into a composting area. By using it as a composting site (and covering with plastic to insulate) you can have your beds ready for spring with less effort.
