Winterizing my beehives.
There are many ways to do this, this is just one perspective.
Far left: Homosote. It is basically papier mache. I put this on the top of the inner cover to absorb some of the moisture in the hive. Moisture can kill bees.
Second from left: is insulation. A layer I put on top of the homosote to just help the hive stay warm-ish.
Black roll: is tar paper. I wrap my hives in this tar paper to help the hive absorb heat during the day.
Far right: I can't remember why I put this in this picture...it is a deep body.
Hope this helps. Would love to hear what you do. A few more thoughts
