Interesting facts about fruit, pollination and reproduction

Reproduction of the birch

the The birch is in bloom begins - depending on the location and the given climatic conditions in the respective year - roughly between March and May. Male and female catkins, i.e. the blossoms of the birch, are on the same tree. That is, birches are monoecious with unisexual flowers. The fruits then emerge from them.

Pollination and spreading via the wind

While the male kittens are already formed in the autumn months of the previous year and then overwinter, the female flowers awaken only fresh at the ends of the new foliage Young shoots. The kittens are pollinated exclusively by the wind. The birch plants are not capable of vegetative propagation or stick rash.

The seeds of the birch

The either upright or loosely hanging fruit stands are provided with thickened, slightly leathery scales. When the winged nuts, also known as samara, are released, the scales fall off one by one. So that the

Birch seeds can spread over long distances with the help of the wind, they lie in tiny nuts that are endowed with delicate wings. These wing nuts are the fruits of the birch tree. Since the pioneer plants in nature have to be quick and efficient, the seeds germinate after two to three weeks. The extremely light and airworthy fruits ensure this rapid generative reproduction.

Birch fruit season

Birch trees can already produce fruit when they are only five years old. Birch trees draw on abundant resources: they produce around 450 fruits per single kitten alone. These ripen in midsummer, only to be scattered in autumn and winter. They germinate the following spring.

The fruit of the birch

The birch fruit ripens in the period from July to October. The extremely thin-skinned winged nuts are only up to three millimeters long. Thanks to this tiny and lightweight design, they are optimally designed to be dispersed by the wind.

Plant your own birch by fruit

When sowing the seeds, do the following:

1. Fill small bowls or pots with Potting soil.
2. Then add the seeds of the birch.
3. Then cover the seeds about an inch or two high with soil.
4. Then set up your breeding pots in as bright a location as possible.
5. However, avoid strong direct sunlight.
6. Wait about two to four weeks while keeping the substrate slightly damp - but not wet - at all times.
7. Within this time the seeds will germinate.
8. Once the seedlings have reached a height of about 15 to 20 centimeters, you can finally transplant them into a more nutrient-rich substrate.

Are the fruits suitable for consumption?

The fruits are of no great importance for consumption or for the versatile medicinal ingredients of the birch. If you like, you can brew the small wingnuts to make a pleasant tea. For the tea infusion you should mainly use the young fruits. However, the following edible components of the tree are better suited for further processing:

• the leaves with high levels of flavonoids, saponins, tannins and vitamin C.
• the bark with the active ingredient betuloside and betulin
• the buds of the birch through their oils
• the juice of the strain for cosmetic use, for example as a hair tonic or for skin care
