Hi Rick, I am choosing not to treat this year, for one reason these are all first year hives and I think they are ok, Hoping anyway. Not sure about a fall flow here but I know there is a ton of golden rod around, close to twenty acreas right here! Last year I got about five frames of honey off of the goldenrod, I thought it was pretty good. Kinda hoping that I get some this fall too. I put supers on three hives that I thought were really booming but they didn't or at least last time I checked they hadn't drawn any comb in them even though the thistle was in full bloom> Now the thistle is gone. I did plant some more buckwheat but I think if all goes well it will be close to the end of august before it starts to flower.
