Well, believe it or not many greenhouses are now pollinating with bumblebees!
They don’t forage over too large an area, sting less, and are not susceptible to the latest colony disappearances.
When I used to have my 24 X 96 greenhouse full of tomatoes, I felt that the shaking wasn’t quite doing the job, so I took a ball of cotton and glued it to the end of a dowel rod. It only took a gentle tap on each blossom with the cotton ball and the yield went very noticeably. Not only did I find that pollination was better, but I was much more in tune with what was going on in the greenhouse - aphids, and other bugs as well as re-tying the vines.
Interesting to know, so they too want personal attention, or do not give out the fruit.
So much to learn.
Good idea about pollinating the tomatoes. I never heard that before but will be sure to try it.
