he's not talking about nadiring just one shallow but stacking the whole lot under the brood box for the whole winter
At last, someone referring to shallows and not mis-using the word ‘super’. Obviously the Latin language is long gone, but they, at least, would have known what ‘super’ meant in this cntext.
There are a few posts which demonstrate that many beekeepers don’t really think about what they are doing and how to avoid future problems from their hive interferences.
Spreading the frames in a nadired shallow is the simple way to avoid waxmoth infestation - which is only most relevant to comb which has been brooded in previously. ‘Wet’ frames
will be ‘dried’ by the bees, given the opportunity.
Bees will clean up any moulded comb before further use. They have better food storage habits than some of their keepers?
No matter how close the boxes fit, rain gets in; outcome is mouldy combs.
Putting boxes elsewhere at the end of the season needs some consideration, from the beekeeper, towards the well-being of the bees. The bees will always seal small gaps with propolis - given the opportunity - but many shift boxes (breaking propolis seals) late in the season, without any due consideration for the bees. Securely strapping the boxes together avoids virtually all possibility of water ingress from winter storms - unless the joints between the boxes is rubbish.
Properly insulated, and bottom ventilated, hives do not encourage damp conditions, thereby reducing the likelihood of mould on frames.
i know a friend who stores them above closed CB and under roof, wet....so no access for bees but stored on hive....
Those who know anything about waxmoth would know that keeping the frames warm would encourage the possibility of comb damage. I, for one, would never consider putting an empty shallow above the cluster such that it might be warmed by the bees’ activities. With access to the bees or not (I would not leave any more space above the bees than the absolute minimum - insulation directly above the crown board is required, ideally).
taller top heavy hives in windy winter months might be more likely to topple
Not if the beekeeper thinks, and actually takes preventative action, before it can occur. Beekeepers need to think a little more about separate free-standing hives than those on securely fixed multiple stands. It is usually only those that don’t think, that suffer with toppled hives. Same as multiple hives floating away during times of flooding…
Beekeeping is simple - but only when you think about what you are doing, and why you are doing it!
