Maximising Honey Production After a Vertical Split (My Method in Spring)

I thought I’d share the step‑by‑step method I used this spring on a FlowHive colony that came into the season very strong and started building swarm cells. Instead of letting them swarm or doing a standard artificial swarm, I used a vertical split to raise a new queen and keep honey production high.

It’s now been six weeks, the new queen is laying beautifully, and the colony is booming — so here’s the full breakdown for anyone interested.

1. Starting point: strong spring colony with swarm cells

The colony was packed with bees, nectar coming in, and several charged swarm cells. Rather than lose half the bees, I used the situation to my advantage.

2. Setting up the vertical split

I separated the colony into two brood boxes:

  • Bottom box: Old queen, some brood, and stores.
  • Top box: Brood with swarm cells/young larvae and plenty of nurse bees.
  • Between them: A split board/double screen so they share warmth but operate as two colonies.
  • Upper entrance: Added so the top box could function independently.

This keeps both halves strong while preventing an actual swarm.

3. Allowing the top box to raise a new queen

The top box was effectively queenless, so they continued developing the swarm cells.

I left them alone for mating and checked later for a good laying pattern. Once I saw solid brood, I knew she was established.

4. Both queens established

At this point:

  • The old queen was still laying steadily below.
  • The new queen above was laying well and building up her own population.

Two queenright units stacked vertically is a huge advantage for colony strength.

5. Moving the old queen away

Once the new queen was confirmed, I moved the box with the old queen to a new location in the apiary.

This prevents flying bees drifting back to her and lets that colony rebuild in peace.

6. Putting the new queen in the prime position

I placed the new queen’s brood box on the original stand — the location all the foragers are oriented to.

Then I turned the split board/entrances so all flying bees returned to the new queen’s hive below.

This instantly boosts her colony with a massive forager force.

7. Adding the Flow super for maximum honey

With a young, vigorous queen and all the flying bees now working for her colony, I added the Flow super.

The result:

  • Strong brood nest
  • Huge forager population
  • Excellent nectar intake
  • Fast filling Flow frames

This method has given me one of the strongest honey-producing setups I’ve had after a split.

Great breakdown, thanks for sharing this!
It’s very useful for anyone dealing with strong spring colonies.

I’ve found it amazing that you can manage swarm control and still end up with plenty of honey — plus a strong new colony ready for next year.
