Over the 9 years I’ve been using horizontal TBHs (HTBHs), I’ve seen many experiments in design and use. This article is intended to help those considering one find their way through conflicting advice.
Some early HTBH guides essentially promoted a gentle style of conventional beekeeping in an odd shaped hive which was regularly manipulated. Since then, enthusiasts in the UK have consistently found that allowing local bees to largely run the well-insulated non-framed hive, which is not treated with miticides and only opened occasionally, makes varroa a non-issue.
This survival rate graph indicates this ‘natural’ or low-intervention approach creates colonies at least as resilient as the more intensively ‘farmed’ bees. (Though BBKA surveys ignore colonies under 5 frames going into winter.)
Allowing the bees themselves to determine how the colony is run, and taking a ‘survival of the fittest’ (Darwinian) aproach, I do not replace queens. With six hives, I view a colony failure as simply weeding out the weak and an opportunity to restock with a swarm from a stronger strain. I do not merge weak colonies as there is no way to tell which queen is fitter. Continue reading
