The National Bee Unit issues alerts. I received an alert today (15th June) about starvation. I received one last year on 30th June. It's getting to be a habit.
I've been anticipating a nectar flow from the Lime trees next to my out apiary but it now looks like that won't happen. I visited the hives this evening and it looks pretty certain that the two newly established colonies (Hives F and G) have very low stores.
