Does that apply to all willow species? I regard it as a vital component for
colony buildup; I've always noticed that colonies only really build up after
the willow becomes available. A cold spring like the last, when the bees were
unable to work the willow, always leads to a delayed buildup. Once they can
work it, it's covered in bees, and I see little else coming in until
dandelion becomes available in turn. So I'm surprised to see that it's being
suggested that a diet of willow could lead to colony decline!
