This year I have a lot of OSR around however with wind from the N Sea and a daytime temperature of 8 or 9 degrees and frost in the mornings, my bees haven't got much in yet and colonies are behind this year. I believe that a reasonable temperature is needed for OSR to yield. So, no supers just yet for me; there is little in the way of liquid strores in hives and some have needed feeding.
Forecast is for wind from the north for the next week. However once the temeperature increases, I hope that the bees will start to do well. The supers are ready to go on.
