The numerous flowers only promise a good yield if a male grows near the female plant. This is required for fertilization, since kiwis are dioecious plants. One male plant can fertilize several female plants. The cultivars with hermaphroditic flowers, on which the male and female organs combine in one flower, do not need a fertilizer.

How do you recognize male and female flowers?
If you are not sure whether you have planted a male or a female plant, you can tell by the flower. The female flowers have a white style in the middle, around which yellow stamens are arranged. In the middle of the male flower, however, there are only yellow stamens.
Flowering time and fruiting
In the case of the kiwi plants you grow yourself, it often takes ten years or more for the first flowering. The grafted kiwi bushes from the specialist trade already bloom in the third year of standing. The kiwi bush is in full bloom at the beginning of June. Fruit formation is influenced by various factors:
- Nutrient and water supply,
- Location and soil conditions,
- Cutting measures,
- Weather conditions.
Depending on the variety, the fruits are about 5-10 cm tall, elongated and initially smooth and later hairy skin. They ripen in late autumn, are harvested immature in October / November and ripen during storage.
