Time is not the issue it is timing. You don't want to get robbing started down south this time of year, but if you don't feed they will not build up. Talk to some of the local beeks would be my suggestion and see how they do it. Also do a search on dry feed during a dearth.why would it bee to late down there? i am still making splits and nucs up here in Montana and i continue to make some more in July. You just need to give them the feed and push them. I think it is pretty funny that you guys worry about starting hives down south and up north here spring/ summer has just begun and the flow last year was over about the first week of sept. Seems to me you would have plenty of time yet.
