Re: Combining late season swarms with queens?
Start them off in nucs and add a second 5 frame deep as they grow. A 5 over 5 nuc will do just fine in your area. Probably get away with a single 5 frame deep if you keep the feed on them. To put it in perspective, I am still making walk away splits here in Richmond and our climates are similar. Mine will overwinter as single 5 frame deeps. I was 9 for 9 last year doing this.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
