BFB,
We still have maple and some fruit trees blooming, I has also seen Redbud blooming. Not major blooms but enough for build up. Our major bloom is gallberry, Palmetto, and Blackgum. They run from April to mid June. Our weather usually allows us to split and then build up for the flow. The bees are in town and I will move them here just before BeeFest. Once here I will have to feed them until the flow starts.
