This is how the pollination of tomatoes works in closed rooms
Since tomatoes are mostly self-fertilizing, im take over Outdoors the wind and insects do this important job. Bumblebees cling to a flower and make it vibrate. Because of the vibration, the pollen buzzes around and fertilize opened flowers. Mother Nature's hands are tied behind glass, so that amateur gardeners can pollinate themselves. These methods have proven effective:
- in the greenhouse and on the Windowsill Shake tomato plants vigorously repeatedly
- on individual tomatoes in the pot Brush over the flowers with a soft brush
- alternatively with an electric toothbrush Climbing aids vibrate
- all methods are to be carried out on several days in a row

Pollination works very well as long as the relative humidity is between 50 and 80 percent. In addition, the pollen clump together and are no longer released. If the value falls below 50 percent, the germination capacity of the pollen is reduced. In addition, the
temperature not crack the 30-degree mark. Experienced hobby gardeners therefore invest in a hygrometer and a reliable thermometer.Single variety propagation thanks to targeted pollination
As long as you have the plants of a single Variety of tomato cultivate, pollination takes place in the greenhouse and on the windowsill. On the other hand, do other breeds come into play or do wind and insects get hold of them Growing tomatoes outdoors, varietal purity is no longer guaranteed. Strive for the hand-pulled harvest Tomato seeds for propagation, you can prevent unwanted cross-pollination with a simple trick.
Before the flowers open, either cover the entire plant or individual flower panicles loosely with a close-meshed insect net. The petals must still be able to unfold underneath. Excess flowers are broken off. Suitable materials for an insect-proof cover are tulle or gauze. A single tomato blossom can also be protected from cross-pollination by means of a tea filter.
Even the most skilful pollination will not be successful if the tomato plant does not develop vital flowers. A careful one care thus represents the foundation for the entire process. The water and nutrient supply must be in balance as well as that Site conditions.
Tips & Tricks
The vast majority of Varieties of tomatoes is self-fertilizing - but not all. Wild tomatoes, for example, are not included. Instead of messing around with lengthy strain descriptions, just take a look at the flower. If the stigma protrudes from the petals, it is one of the rare non-self-fertilizing varieties. In this case, a second tomato plant is generally required for pollination.
