I am not a BUMBLE BEE expert but the first thing I would want to know about
is any changes in lighting conditions in that green house from last year to
this year.

I would fist look for a new source of BB's, then I would try to increase
the amount of light in the green house and hope that gets the lazy BB's out
to work. I would also look at the seed source as if the plants produce no
rewards for the bees then all the above is wasted effort.
Again I am not a BUMBLE BEEMAN. If I were you would not bee getting this
information for free.<G>
