Re: Minimum Temperature Outside To Split
I bet you get a lot of differing opinions on this one. Here's mine. Daytime temps around 50, nightime temps should be above 30. Much depends on the type of split and how many bees you put in. A double deep hive can easily donate two frames of brood, a frame of honey, and three shook frames of nurse bees to populate a nuc strong enough to survive dips in the temps. I made two splits 11 days ago here in Richmond. Since then, the daytime temps have been in the high 40s and night have dipped into the low 20s. One nuc had too many foragers in it and failed, killing a bunch of brood in the process. The other nuc has a strong cluster and has produced three capped queen cells. I don't think temperature had anything to do with the failure, more like beekeeper error.
What is ths two week forecast in your area? Days over 50? Nights around 40? I would go for it. Just make sure the splits are strong.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
