Who of us is unfamiliar with this beautiful and touching tree with a covered birch-white or yellowish trunk? It grows to 30-45 meters in height. The leaves of the birch are round or lanceolate, jagged along the edges. The plant blooms in the spring, before the leaves start blooming. These flowers are collected in earrings.
The fruit of a birch is called one-seeded nut, it has a size of 1-5 mm. It has two webbed wings. It is a flattened lenticular nutlet, on the top of which there are two withered stalks. Ripening occurs between mid-summer and mid-autumn.
How many times does the birch bear fruit?
The fruit of the birch is formed when the earrings are fertilized. This is as follows: in the spring, male earrings that have wintered in the closed state are lengthened, the scales of the flowers are opened and stamens that excrete pollen become visible between them. During this period, earrings slightly bend and then hang. Women's earrings grow on the tops of shorter shoots, which develop laterally on last year's shoots.
Male and female earrings bloom simultaneously, and after fertilization the female lengthens and thickens due to the increase in the volume of scales. Gradually, it turns into an oval or oblong cone.
How many times a year does the birch bear fruit: once. As already mentioned, the ripening of fruits takes place in the summer-autumn period. Depending on the climatic conditions, this can be a period from July to September. After maturing, the fruit bud is showered, the rod remains from it.
How much does the birch bear - since the birch is able to live 100 years or more, and the first fructification is about 10-20 years, depending
Birch - agricultural technology
In the Northern Hemisphere, birch grows well on moderately moist and not very dense soils rich in humus. The growth of trees is not greatly affected by the composition of minerals in the soil. The only thing is that it grows poorly on lime soil.
The plant is photophilic, so it needs sufficient sunlight. Often grows in a mixture with various coniferous species, overtaking them in terms of growth rate.
If you want to grow birches as ornamental plantations, remember that they dry up the soil, grow faster than other trees, and get along well with firs and rose hips.
