2 of the older beekeepers in my area insist that bees only gather pollen from golden rod, that it is not a nectar source. I hate to argue with these guys ( one of them helped me get started with bees 6 years ago). I know my hives always cap a few supers of honey in August when golden rod is flowering. Has anyone heard of this or can prove or disprove this so that I can set them straight in a nice way? Or am I the one that is wrong?
