Re: Did I make a mistake?
Nope, you didn't make a mistake. For your location, you should be encouraging the bees to pack honey into the brood nest which will push the queen down to laying in the lower brood chamber. All honey supers should be removed by this time. One caveat to this is if you wanted some fall honey, you could have left the super in place until it was capped. The problem with doing so is that this might leave the bees short of stores for winter.
Would it surprise you to learn that bees in Augusta use more honey over winter than bees in a much colder climate? The reason is that your winter temps are often warm enough for the bees to fly and forage even if there is relatively little to bring back because nothing is blooming.
