I made this mistake when I first started keeping bees.
I didn't think I would get any honey the first year so I didn't think I needed to put on honey supers. What a mistake.
The bees collected so much honey that the brood nest was plugged solid. The queen had no place to lay. The hive dwindled and didn't survive the winter.
Now I make sure all of my colonies have honey supers on.
A hive can put up so much honey in a short time that if it is not checked at least weekly can plug up the brood nest also. I always am two supers ahead.
Bees have a hoarding instinct. Beekeepers can exploit this by keeping empty supers ahead of the bees. The bees will work harder to fill this up. If the supers get full, the bees may just stop collecting nectar. Having an empty super on top makes the hive get all the honey that they are able to collect.
The weather and the long term forecast is perfect for honey production. Warm days, not hot. Low humidity. Hopefully there will be a good crop.
