Inspecting the hives this morning showed one of my colonies was going to swarm which it did bang on 1100.
However, it very helpfully settled on a sycamore tree about 8′ off the ground and I managed to house it temporarily in a box.
Then after a few hours working my plots, I finished a late lunch to see a swarm coming into my garden. They decided an ld nuc (nucleus hive) I had cleaned up would be a perfect spot for them.
These are not my bees, as I don’t have any nearby. But they’re mine, now, if they choose to stay.
