English summary: Pure sugar syrup gives weaker bees in the spring due to nutrition stress. As a consequence they need to build their strength during the spring and thus no honey harvest is possible during the first flow. If the bees get to keep their own food and we use minimal with chemicals against Varroa,Continue reading “17 april – drönare, skattning och första skattlådan på”

English summary: The first real flow for the season is the Salix that provides both nectar and pollen. We had a terrible storm this weekend that nearly blow the hives away, last image.

Det faktum att bina producerar yngel även fast de inte kan flyga överraskar många biodlare påContinue reading “22 mars – yngel hos våra nordiska bin”

English summary: We have two apiaries, one in a mild coastal climate and one in a bit more harsch inland climate.
