Someone recently asked me about pollinating his greenhouse and I got to thinking about bumblebees. I have heard that bumblebees are great for greenhouse duties, preferable to honeybees. I know nothing of them but find them interesting. How does one manage bumblebees for pollinating in a greenhouse? What sort of "hives"? Can they be moved around like honeybees? Is there a problem with greenhouse enclosures?
Does anyone on this forum manage bumblebees?
