This is our first full year of owning a flow frame beehive, so learning as we go, so to speak.
After looking at what others have said, I concluded that I need to remove my flow super for winter (we are in Tasmania), which I did yesterday. Completely successful exercise. I have two brood boxes (recommended by experienced bee keepers because firstly the queen excluder is hard on worker bees and secondly we need to make sure plenty of honey for winter). The top box is almost entirely honey - so plenty of stores for the hive!
