>> What is (are) the limiting factor? Is it simply that they can't put on >> enough stores for overwintering, or what? I've explained this as clearly as I can, both here and on my website and written reams on the subject, plus chronicled my experience with splits. There is no one factor. It is uncertainty that limits how aggressively an experienced and prudent beekeeper will spit. I don't think I can explain any more clearly than I have without repeating myself. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
