Re: @Pompous Git
The pollen is quite hard to get out of the flowers- they actually resonate at the frequency of the wing beat of the bee that natively pollinates them so when they land they effectively violently shake the pollen out of the flower.
There ya go. Who'da thunkit? Most tomato growers find that gentle shaking of greenhouse tomatoes mid-morning works. The flowers are complete (have both male and female parts) so the pollen doesn't need to leave the flower. Outdoors, the plants are shaken by what many of us call "wind". Commercial growers who beleive we don't get enough extra hormones in our diet from chicken, milk, soya products etc use a spray of Tomset.
