If flowering is the trickiest part of how to grow tomatoes, than pollination must be the trickiest part of flowering. As soon as flowers develop and begin to open, you must pollinate everyday while it is warm and humid. Ideally, the humidity will be 65 to 70 percent. Greenhouse growers usually do this between 11:30am and 12:30pm (basically noon) when these conditions occur naturally. For them, early and late day pollination often will not produce proper crops.
This is a tomato flower. Part A is the male anthers that will drop the pollen. Part B is the female carpels that will catch the pollen. The little red arrow is where it all takes place.Most male anthers produce their pollen on the outsides of the anthers, making it easy to release pollen into the wind for pollination. In the tomato plant, however, pollen is produced internally, as if trapped in a straw. This is the biggest problem for tomato pollination.
The plant needs vibration at the right frequency, such as the buzzing of a bees wings, to dislodge and release the pollen. The best way I have found to do this is to take an electric toothbrush to each support truss and main branch. The more pollen to successfully fertilize the plant, the more seeds will be produced in the fruit (and therefore the meatier the tomato will be).
