Re: Expanding Top-Bar Hive
Greg nailed it. There is no nectar and no pollen coming in right now. The bees are in contraction mode. You may be able to stimulate wax production by feeding heavily and giving pollen sub patties. That would be a personal decision, and could cause you to go into winter with a hive that is too strong for the accumulated stores to feed. Around mid-August things should get better, just need to get through the next four weeks.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
