Well the fringe in my garden is getting longer. This October swarm has gone nuts. I checked the 4th box a few days ago and virtual fully drawn after a couple of weeks. 2 end bars had cross comb - first time for a few years - which I divided (nectar only) and a reasonable chunk fell off. Went back today with a view to taping it up but the bees had already fixed it not crossed. Added 5th box. Thought of @tristan as I hefted top 2 boxes up together- gym work paying off!
Routine @Bee Real. Its an adaptation of Emile Warre’s design. The “frames” are a top bar with side bars - no bottom bar (although I’ve seen photos with bottom bars). No foundation so the bees build comb as they choose. Provided the bar spacing is reasonably accurate they don’t cross comb. I’ve had a couple of cross comb over the years - if you check for itearly it’s easily fixed.
