I made a move this year into a zone where goldenrod is plentiful. This looks to be a good year for it, the late blooming is getting started this week. What is the best strategy to use to harvest some? All my hives are in their winter configuration now. Should I allow them to backfill their nest, then add a super for myself, or add an excluder and super right away? I'm only looking to harvest from my large hives. What strategy do those with experience use?
