He also inferred that you can split and still keep a strong hive for honey production:
3 frames are enough to start a new colony and it doen not disturb much honey yeild.
Making a 3 frame split into a nuc not affect honey production more than a few pounds for the course of the season, but it allows the beekeeper to still increase his apiary and, to an extent, control the swarming tendency.
Best methods to limit swarming:
1. Split hive, removing old queen. Split can be between 3-10 frames.
2. Provide plenty of room to prevent overcrowding, add supers.
3. Keep bees building comb in or at the edges of the brood chamber. This a good way to rotate out old brood combs that can either be melte down or used as bait frames in bait hives or swarm traps.
There are a few other, minor considerations, but those are the major ones.
Without controlling swarming or providing sufficient storage/curing space for the nectar, the honey harvest will be deminished.
