Beekeeping and Bees

@beekeeping When is the latest you would consider a walk away split (no queen to introduce) in the season?

I'm Zone 6A and I have a single brood chamber colony filling honey boxes (one with wax being built) and still keeping stores below on what would otherwise be brood nest. They're not bound, but it's definitely not as organized as I'd like.

I prefer single brood, but if it's too late, I can throw another deep with waxed frames on top to let the queen really go for it.
