I might be a bit early with this question, but I’ve got a hive with a regular/traditional shallow super on it which the bees might not have enough time left to fill and cap before the season is over and I have to get the hive winter-ready.
Maybe the uncapped honey might be ready and whatever is there can be harvested anyway, but I probably should not count on that. I don’t see how storing (partially) uncapped frames could work and I do not like the idea of the bees losing warmth to the super, in the winter. So, normally, the super would have to come off for the winter.
However, what do you folks think of this idea:
What if I would place a wooden board in between the brood box and the super (like one would a queen excluder), and have only a small hole in it of, say, a couple of square centimeters. This way, the warmth of the colony does not seep away to the super (as much), but the bees can visit the super to make use of the uncapped nectar/honey that is still in the frames.
The same could be done with supers containing flow frames, I suppose, but I have no idea if there are any risk involved in letting the flow frames out in the winter.
I’d be intereste in your thoughts on this idea.
