Exactly!
Its just like plants that need a cold period before they will germinate.
I do not say nonsense, but it is quite near, that I say . Bee has developed in Africa.
Bees have day lenght based biological calendar. Even in our climate, when out temps are -20C, bees start small brood rearing in February.
I cannot understand, what Juhani means by warm winter. If bees are wintered in cellar in winter, they develop as well in soring. Cellars are often +5C.
After warm winters colonies do great in Finland. But " Warm winter" here means -5C and in north -10C winter. Vain to compare to UK.
In our country willows start to bloom at the beginning of May, and nature stops blooming 10th of August. It tells about lenght of winter.
The most dangerours to colonies are long frost period, when cluster cannot reformulate and seek for food combs. If -25C temps last 2 months, lots if colonies will die.
But the basic is the bee breed. If you buy queens from Australia, the hives will be all dead in May.
Our bee researcher had 10 anatolian hives and all were dead after 2 winter, even if they did not have brood during winter. Food consumption was huge. In Balance hive 60 kg/winter, when normal consumotion must be 10-15 kg from September to Marsh/ cleansing flight.
