How to insulate a top bar hive for winter
This my first year of beekeeping and I'm getting ready to winterize the top bar hive. Anyone have suggestions as to what I can use to insulate it once the weather gets cold here in North Carolina? Right now I just have a tarp over it on three sides with the front still open so they can get out and forage on the warmer days. If it's a typical NC winter we'll only have a few days where the temps go below the 20s overnight and not a lot of snow or ice. We do usually have quite a few days of cold rainy weather during the winter. What do you top bar hive folks use for insulation?
Average is just as close to the bottom as it is to the top.
