Well, the hour is upon me. In my sixth spring I've finally reached the point where I just have too many bees and am not sure what to do about it. As I mentioned on some other threads, the blackberry flow finally kicked in after a nectar-less early spring, and I went from 3-4 box hives to 6 box hives today. Several things are different this spring that brought this to a head. Firstly, I've reached the number of hives that I want, which is 10, so I don't really want to split any more colonies for increase, which is what I've done at this stage (or actually before it) in past years. Secondly, I came into this season with a prodigious amount of drawn comb, about a third of which had some honey and pollen in it, which meant that even though my early spring flow was very weak, the colonies were able to grow pretty rapidly because I was able to give them drawn comb and emergency stores, and the ones that came out of winter strong actually built up faster than normal.
My problem mostly lies in the fact that I use 8-frame mediums, so I have to add boxes rapidly, and at 6 boxes the hives are basically as tall as I can manage. I'm 5' 7" and at 7 boxes tall the top box would be above eye height for me. But at the rate the bees are bringing in nectar, they are going to need more room before the blackberry flow is over.
I can't split and keep all the colonies I'd create, I don't have the space or desire for more. If the colonies swarm the same applies, I can't/don't want to catch and keep all the swarms, but letting them fly off just feels like a waste. I can prevent them from swarming by continuing to open the brood nest, but if I do so, the hives will get too high for me to work. And I'd like to keep them from swarming because they'll put up a ton of honey, but the way things are stacking up (pun intended), I also can't add more supers or the hives will be too tall. What should I do?
