How do you handle a Flow super at the end of the year? I’m sure by the end of the honey flow most of the frames will be partially filled. Probably should just wait for them to cap whatever they can and then harvest?
Harvest what they have when the flow is over, give them a day or two to clean up and then remove for winter.
There are a few threads about this. You might consider harvesting and taking the super off sooner so the bees have a chance to fill up their brood boxes for over wintering instead of you robbing and having to feed them. This is what I do. My flow super is actually already off for the year.
