That brings up the most important point of this conversation. All Beekeeping is Local. What works in North Wisconsin may not work in Finland or Florida. Take all advise at your own risk.
that is the point. And every hive is individual. Does it have 5 or 15 frames brood.
Advices is not a risk. Risk is if you do not use your O W N brains.
We are changing here ideas.
you may follow the idea that give to the hive 3 wintering boxes and 60 kg food, ooooorrrr
press into one insulated box and feed 20 kg sugar as syrup.
They are your hives. You may give to them mere honey and they consume your all honey + dry sugar too.
MOST importat, to be succesfull, you must have a bee stock which react in proper way that fall is coming.
I have read that in Britain New Zealand bees are splended but in my climate none on then survive over winter what ever you do.
