The short answer is, “when they’re ready.” Now, don’t get me wrong, I’m not being rude but, as you’ll learn, beekeeping is very weather dependant. Some years, over-wintered NUCs are ready in March, other years, in May. We won’t let colonies of bees go, until they comply with our high standards, as well as complying with FERA’s guidelines for buying honey bee colonies. This is especially true for beginners and less experienced beekeepers, as we want your beekeeping experience to be a good one.
