The plant is unpretentious, so planting is possible anywhere, including sandstones. The tree has the ability to fertilize the soil with environmentally friendly nitrogen.

Planted in the usual way during the vegetative period. The cones of the plant must be collected in autumn time and store on fresh air until they open up.

Seeds are separated using a sieve, after which they can be planted immediately or set aside for the time being. Seeds can be stored for no more than 4 months at t ° 1-5 ° C.

When planting, in order for the tree to take well, it is recommended to prepare a certain substance.

The female catkins of the plant can be affected by a fungus of the genus Tafrina, after which leaf-like growth is observed in the scales.

Mushroom of the genus Taphrin

Take note: the affected branches, as a rule, cannot be saved, and they are simply cut off.

There are also fungi that grow on the leaves themselves, due to which they are covered with spots, and the surface becomes wrinkled. Fungi and other destructive organisms are destroyed by the use of poisons.

Alder. Contraindications

It is easy to distinguish alder from aspen. It is enough to see these trees several times. But if you don't have a picture in your head, this article will help you distinguish these trees even in winter.

By the leaves

Trees are very different leaves. Aspen leaves are larger. The edges are smooth, the shape is classic. In alder, they have jagged edges. The shape is elongated, closer to an oval.

By fruits

Alder is easy to distinguish by fruits resembling cones. In spring and summer they are green, and by winter they dry out, turn brown and ossify. You won't find anything like this on Aspen.

By bark

The bark of these plants is also very different. In aspen, it is smooth, greenish-gray in color, sometimes with a slight bluish tint.

Alder bark is different. In gray it has a pronounced grey colour with a light wood texture. The bark of black alder is dark brown, almost black. In mature trees, it cracks and peels off.

For wood

In my opinion, the most characteristic differences are the properties of wood. If you cut the aspen, on the cut it has an exceptional White color. And alder wood, black or gray, is red.

Freshly sawn wood of light color. But literally before our eyes it begins to blush, leaving in an orange or pinkish hue. This phenomenon can be observed especially clearly in winter, when the reaction is faster.

Using this knowledge, you can easily distinguish alder from aspen. And it doesn’t matter if there are leaves on the tree or it will lie in your yard in the form of firewood.

Green fruit. Female inflorescences turn into a small oval cone up to 2 cm long. Ripe fruit - cone

Green alder (Alnus viridis)

It is a very common shrub (rarely small tree), with dense shoots. Reaches a height of up to 4 m. Creates numerous shoots, bent in the form of a braid. Annual shoots of olive-green or red-brown color are slightly flattened, pubescent.

Earrings - male inflorescences. Leaves - ovate or elliptical, up to 6 cm long, pointed, with double carved edges. The veins are distinctly visible, in the amount of 5-10 pairs, slightly pubescent at the corners. The ripe fruit is a cone. The fruit is spherical or ovoid, strongly lignified, reminiscent of tiny pine cones. Contains nuts. They stay on the plant for a long time.

The buds are convex, conical, covered with 4-6 purple-brown or greenish ciliated scales, sometimes slightly sticky. The plant is monoecious (separate male and female inflorescences appear on the same plant). Before winter, the rudiments of male and female inflorescences appear on the branches, which bloom only in spring. They bloom simultaneously with the development of foliage (April-May) and are wind pollinated.

The plant grows especially abundantly along streams. Prevents erosion and strengthens slopes. Its pollen sometimes causes allergies.

Origin: Found in North America, Europe and Asia (including Siberia and Kamchatka).






She was brought from America, belongs to the birch family. The name comes from "Alnus", which in Latin means "coastal".

The article will introduce you to amazing plant, you will find out how it looks, in what forests you can meet it and where its raw materials will be used. Alder, a photo of a tree and leaves are presented below.

Shrub Description

The shrub can grow up to three meters long. Flowering begins in mid-summer, and ends in the first month of autumn. It has yellow flowers with a white sheen.


The inflorescence has a length of up to 15 cm. This is one of the most valuable varieties of trees. She brings drupes, these are her fruits. It also blooms the very first of the Russian trees in mid-spring, before the wind-pollinated leaves bloom.

The forest is still frowning, undressed, snowdrifts are melting somewhere, and from afar you can already see the reddish tree when it begins to bloom.

If you get closer, you can admire the blackened leafless branches with dangling brownish-red catkins.

Gradually, the decorations inflate and yellow clouds of pollen fill the atmosphere. Small female flowers pollinate surrounding plants, and, as a result, green cones are formed, in which seeds are born.

Why is it ahead of other trees during flowering? Here's why: the previous summer, it was preparing for the oncoming heat. In July, men's earrings are cut on the branches. Until November, they develop, and by January they fully ripen. They contain a certain amount of pollen. It remains to wait only for the first rays of the gentle star.

The female flowers look like a picture of small spikelets of the field. After pollination, as a rule, the leaves are sealed with resin, develop and change, transforming into lumps.

By September, hard lumps become thick and hang until April. Seeds grow inside them. The premature onset of spring contributes to the daily growth of earrings by three centimeters. When the scales are folded back, the flowers bloom and turn into dust.

Light contact with the jewelry forms a cloud of pollen, which releases a lot: from one earring - up to 30 mg. hallmark does not consist in the first flowering, but also in the fact that the fruits ripen in November.

Basically, such vegetation is undemanding. Likes moist, cool soil. Highly resistant to heat and wind. Winter tolerates well, loves the light. Usually propagated from seeds or cuttings.

grows on open places or in the forest. It adapts well to life with other trees: birch, spruce, oak, etc. Feels good in open areas. This is evidenced by the fruits that appear after 9 years. In places with a constant shadow, they appear only by the age of 35. Lives for over a hundred years.

Black - grows up to 30 m in height and up to 80 cm in diameter. Gray - often grows into a dense bush. Sometimes it is no more than 15 m high and no more than 30 cm thick.

The difference lies in the color of the bark and the shape of the leaves. The first species has dark, sticky egg-shaped leaves. In the second variety, the leaves are usually in the form of an ellipse with sharp edges.

Consider where each species grows. The black variety prevails along the wet coasts of rivers and lakes. Gray - can be seen on the withered hills. Freely occupies cuttings, wastelands, ashes.

True, the moisture and nutritional value of the soil are similar. Glued is so named because the young leaves are very sticky. And on the dilapidated trunks of black alder, dark crusts form.

Medicinal properties

The alder tree is characterized by an amazing combination of three colors at once: fiery bark, emerald leaves, dark brown branches. According to popular signs, this depicts the traditional trinity: fire, water and earth.

The vegetation in question is interesting for its beneficial properties for people and other vegetation. It fertilizes the soil with nitrogen. Its roots consist of nodule formations, hiding places for bacteria and nitrogen helpers.

Also highly rated charcoal tree. It is designed to equip anti-chemical equipment, and alder chips are also used for smoking.
