Honey is extremely expensive compared to cane sugar or corn sugar. It is my understanding you can boost a hive’s output by supplementing their nectar with plain old sugar. To boost your honey output you gain more hives, but there is only a finite amount of nectar out there accessible by the bees. So when you reach the point where you have more bees than the land can support, you start feeding them corn sugar. The bees will convert the corn sugar into honey just as they convert flower nectar/pollen into honey
Am I correct on this or what?
No, you are not correct.
Bees work their butts off and during the nectar flow have the capacity to make amazing amounts of honey.
The way honey production is increased is to relieve the bees of the necessity to make wax. Modern bee keepers use rectangular frames with a wax insert in the middle. The insert is embossed with the precise dimensioned hexagonal outline of the comb. The Bees draw out the comb to the depth of the frame that happens to be the optimum depth for storing Brood or honey. The removable frames filled with honey, not the brood frames, are removed and the wax cap is removed with a hot knife that removes only the cap leaving all the honey and the wax cells (the comb). The frames are slung in a centrifuge, mine was hand cranked, and the honeys is removed.
The frames with the wax cells intact are reused the next season, and several more. The ever diligent, and quality conscious bees will make repairs as required except this time the bees are spared all the work and expense of drawing out all new wax. I can’t remember the cost of wax but I will say one pound of wax requires the nectar for 10 pounds of honey.
A bee keeper is intrusted with the welfare of his hives. He watches them and is aware of their well being. If they are low on stores or starting out new from a swarm, feeding them will be of assistance. Sugar syrup is good if no old honey from past years is available. As a very long time observer of bees I am certain that one can not feed enough sugar syrup to make any substantial quantity of honey. A newbie starting out and not knowledgeable might think his feeding syrup is doing a good deed. But unknown to him, when there is even the slightest bloom, the bees will be at work collecting the nectar that is the real source of the honey that just keeps piling up in the frames as the spring progresses.
When there is bloom, the bees will find it. I’m not sure a situation exists where they can bee more bees than resources. They will just fly further. Given the difficulty in protecting bees from disease and parasites now, the question of not enough forage is not at all probable.
