do you collect Propolis??? I have a trap but have no idea when is the best time to do this. Not completely sure of how to set the hive to collect it. My hives are all new this year. Just put honey supers on the first one. Other 3 only have one large brood super. Any advice would be greatly appreciated.
A friend works at a botanical garden and said they would buy all I could supply. Told them I have to first learn about it.
