Im feeding sugar water, and they are sucking it down, but I dont see much in the way of pollen stores, or foragers coming in with pollen. Do I need to be concerned? Do I need to supplement, and can this be done? BTW Im in the central CA coast area. Mark
I would try a small amount of supplement to see what they do. If they take it, keep it supplied. If not, then they think they have enough.
