Just think of the untold billions of words that have been written and spoken on the topic of the supplemental feeding of honey bees.
How about this idea: Plant more pollinator gardens.
I realize that's a simplistic answer; there are many legitimate reasons why a honey bee colony may not end-up with enough stores to survive to the next nectar-flow season.
But why don't we see more discussion about planting pollinator habitat as part of our bee-centered beekeeping conversations? I know that colonies tend not to forage right next to their own hive, but if they could make shorter trips to a nutrient rich, diverse source of forage each day, they could make more trips each day.
As a bee-centric beekeeper, I find that I have to belong to two different kinds of groups: Beekeeping and Permaculture. Of course, I cross-pollinate between the two (pun intended), but it seems counter-productive to bee-centric beekeeping that healthy pollinator habitat is not a part of our core conversation.
