The problem as I see it was the relentless poor weather from June, low temperatures reducing the effectiveness of thymol treatments, no ivy pollen in the autumn followed by a winter far longer than usual.
My losses were due to spring dwindle. There were not enough bees produced in the autumn and the bees in the overwintering clusters did not live long enough.
When a nuc or a colony get down to less than 3 frames it is usually on the way out and is very susceptible to either isolation starvation of freezing if there are several days of sub zero weather in the spring.
