So How many boxes do you need going into winter?? Is it true that the more boxes you have in place is more space for the bees to heat? We don't think so. In fact, the number of boxes you have on the Warre should be at least 3.. in our humble opinion.
For the record, we do not wrap our hives in any way. We make sure they Quilt box is fully and fluffy, and we sometimes turn our propolis screens 90 degrees to open up some ventilation routes.
