The genus of deciduous trees tilia, or linden, has about 45 species. Most of them grow in temperate and subtropical climatic zones. The distribution area includes Europe, Southeast Asia, the Far East, the North American mainland. The linden family belongs to the relict ones that existed on the planet in the pre-glacial period.

Description

Depending on soil fertility and illumination, both large woody forms of linden plantations and small shrubs are found. In its natural environment, linden adapts to almost any habitat conditions, but prefers well-moistened nutrient soils. These species are characterized by frost resistance, the ability to tolerate wind and drought.

A characteristic feature of lindens is their low susceptibility to diseases and insect pests .

Many species are long-lived, the age of the trees is 300–400 years, and older specimens have been recorded - 1000 years old. Trunks of large species can reach a length of more than 30 m, trees begin to branch at a height of 1.5–2 m from the ground, by the age of 30 they usually become mature. The bark of young plantations is brown or olive in color, smooth. In mature trees, it is dark thick, dotted with deep cracks. The crown is oval ovoid, very dense. The root system is powerful and developed, penetrates deep into the soil.

The leaves of the linden are heart-shaped, wide and rounded at the base and pointed towards the ends, matte or dark green. These plants are excellent honey plants. In early June, fluffy yellowish flowers bloom on them, collected in inflorescences and secreting nectar. In autumn, in their place, linden fruits are formed - small nuts with seeds. The flowering period lasts about 2-3 weeks. At this time, the tree emits a specific pleasant aroma that attracts bees. Linden honey is considered by many to be the most useful and delicious. In addition, linden is a well-known medicinal plant, since its flowers and buds have a pronounced anti-inflammatory and diaphoretic effect. This herbal raw material is part of the fees for the treatment of respiratory diseases and SARS.

Linden species

Lindens can grow singly, but most of the plantations are in forests. The "favorite" neighbors of these trees are ash, oak, pine, maple, spruce. In addition to mixed forests, lindens form large-scale pure plantations.

In the wild and cultivated, both pure and hybrid varieties of the tree are found.

small-leaved

Another name is heart-shaped linden, due to the shape of the leaves. This species perfectly tolerates adverse environmental conditions, including strong winds, drought and frost. The life span of a tree can reach 400 years or more. In the process of growth, its trunks stretch to a height of 25–30 m, the branches form a spreading crown, similar to a tent: the upper shoots are directed upwards, the middle ones are almost horizontal, and the lower ones look down. The leaves have a relatively small size - about 3-4 cm, heart-shaped and pointed apex. Their upper part is glossy and dark, the back is lighter, slightly rough to the touch. In June, small-leaved linden is covered with fluffy panicles of inflorescences of 6–8 flowers; in August, small nuts with seeds inside ripen in their place.

This type of linden is distributed throughout Europe, including its Russian part, in the Caucasus, in Western Siberia.

large-leaved

This species is outwardly similar to the small-leaved, but it tolerates severe frosts worse, therefore it grows mainly in the southern regions of Europe and the Caucasus. Many large-leaved lindens are real giants and centenarians: they can grow up to 500 years of age. In cross section, their trunks reach 80–100 cm, and rise to a height of 40 m. The leaves, in accordance with the name of the tree, are large in size - up to 14 cm, edges with small teeth, slightly pubescent on the back. The crown has an almost pyramidal shape. The inflorescences of this linden are much smaller than those of the small-leaved linden: 2–4 flowers each. The flowering period lasts 2 weeks from mid-June.

The large-leaved species prefers fertile soil, but the trees themselves improve its composition: the foliage that falls in autumn quickly fades, forming humus. This linden is often planted in gardens and parks, as it has high decorative qualities, forms a dense shade, and purifies the air.

ordinary

This is a hybrid species formed in the natural environment with the help of cross-pollination of large-leaved and small-leaved. According to the properties, the height of the trunk, the shape of the crown resembles relatives, it begins to bloom a few weeks earlier - at the end of May or in the first days of June. Inflorescences - as in a small-leaved variety, the leaves are dark green, smooth, covered with sweet juice when flowering, attracting bees. Common linden is a good honey plant. In addition, it is excellent for landscaping in urban areas: it withstands polluted air, dust, wind, frost, lack of sunlight, and is not sensitive to drought.

Manchu

In Russia, it is found in the forests of the Far East, but, being planted in European regions, it takes root well in them. It loves moist soils, is frost-resistant, tolerates shaded places well. The trunks of the Manchurian linden are often branched and relatively low - the maximum height is about 20 m, the crown is sprawling and dense. The leaves of this species are very large - 25–30 cm, pubescent, the inflorescences are also powerful, consisting of 10–12 flowers.

Caucasian

This species prefers a warm, humid climate and fertile soils, grows in the forests of the Caucasus, Crimea, and is also found in Asia Minor. The Caucasian linden lives up to 400 years, its trunks reach more than 1.5 m in diameter, and the trees stretch up to 35–40 m in height. Young shoots are reddish in color, darkening with age. The leaves are large - up to 15 cm, bright green in color, slightly pubescent, with a lighter shade on the underside. The tree blooms in late June or early July, the inflorescences are large and fluffy, drooping down. The fruit is a nut about 1 cm in size with a seed inside.

European

The main habitat is mixed and deciduous forests of Western Europe. These trees live for 100-150 years, they look powerful: they reach 1.5-2 m in diameter, 40 m in height. The foliage is bright green, heart-shaped, its back part is rough. The crown is wide and dense, the bark of the tree is dark gray, in adults and old specimens it is covered with deep cracks.

Silvery

This linden has pronounced differences from other species. The color of its foliage is dark green, the back side is grayish-silver, covered with thick fluff. Thanks to this, the tree has a second name - felt. The leaves themselves are medium in size - about 7-8 cm, at the height of summer their edges are slightly wrapped inward, which is why the crown has a beautiful variegated silver-green hue. In autumn, the foliage does not turn yellow, but withers, remaining on the branches for a long time. The flowers are very small, yellowish.

Young shoots of felt linden are also pubescent, becoming smooth over time. The bark of the trees is gray, as the trunks mature, it darkens and coarsens.

The species is distributed in the Balkans, in Western Europe, the Crimea, the Caucasus.

Reproduction and care

Planting lindens is a great way to create a beautiful landscape that is appropriate for house adjoining areas, squares and parks. These trees improve the microclimate, fill the air with the pleasant aroma of flowers in summer, and when planted outside the city, they allow the collection and use of useful color.

It is possible to propagate trees by seeds, but it is very laborious and time consuming. Not all of them remain viable, and, given the long dormant period, seedlings can wait more than one year. It is much more rational to use layering or basal shoots of linden as planting material. To root the layering, the lateral lower shoots are inclined to the soil and fixed, lightly sprinkled with it. It will take 1-2 years to wait for the roots, then the branches just need to be released from the soil and separated from the tree. Do it at the end of March.

From the roots of the linden, new shoots make their way up quite often, one has only to carefully detach them from the mother plant. You can also purchase ready-made seedlings.

For planting, a mixture of soddy soil, humus and sand is preferable. Holes are dug in proportion to the size of the roots of the seedlings, so that their upper part is flush with the surface. Drainage from broken bricks or small stones is laid at the bottom. The distance between the pits when planting several trees is at least 3 m.

Care for young lindens requires careful care. In the first 2–3 years, weekly watering is necessary, top dressing at least once a month with nitrogenous fertilizers. For the winter, it is important to warm the seedlings with mulch made of sawdust or pine needles. Mature trees can not be watered, and they need to be fertilized 1-2 times a season.

Trimming branches to form a crown begins no earlier than the third year of life.

Wood

The massif is represented by equal-density sapwood of pale yellow or pinkish color. The texture is weakly expressed, the natural pattern is a bit like a birch. The gloss of the surface is soft, slightly matte.

The quality characteristics of linden wood are somewhat lower than those of pine or oak. The overall shrinkage factor is 0.58. During the pre-drying process, the wood almost does not warp or crack due to the uniform saturation with moisture. The density of dry lumber is about 450 kg/m³. The strength and resistance to mechanical stress in linden is small, similar to aspen wood. It is prone to swelling, does not hold nails and staples well, and is prone to rotting and fungal attack.

The advantages of linden are plasticity and ease of processing: the material bends perfectly, is cut, sawn, impregnated with coloring agents and stains, glued and polished.

Linden has long been used for the construction of barns, beehives, chests, chests, barrels for sauerkraut, vats for winemaking, and kitchen utensils were made: scoops, ladles, spoons, pots. Bast was especially valued: bast shoes were woven from young bast, mats were knitted.

Today, linden is used in furniture and turning production, toys, pencils, blanks for decoration are turned from it. Saunas and baths are sheathed with linden lining, shelves are made from boards. Due to its low thermal conductivity, this wood reduces the likelihood of burns when touched in a hot room.

If you want to enjoy the amazing smell of your blooming lindens for a longer time, plant large-leaved and small-leaved lindens nearby.

Winter-hardy from the latitude of St. Petersburg and to the south. Durable, can live up to 300 years.

In medicine, inflorescences, leaves, flowers of the plant are used.

Landing: Linden seeds must be stratified before sowing and this is done for 3-4 months in wet sand, wrapped in gauze and put in the refrigerator.

It can be planted in the spring both immediately in the ground (early May) and at home at any time, starting in February.

The method of sowing at home is even more preferable, the seedlings turn out better, and as soon as the seedlings stretch to 10-15 cm, they can be transplanted into the ground, either into the garden for further growing for 1-2 years, or to a permanent place.

The soil for sowing linden should be loose, ventilated, for this you can add a little peat or rotted sawdust. Also, gardeners often add sand to the ground in order to loosen it. The depth of seeding is 1-1.5 cm.

After sowing, the box is covered with foil and placed in a warm place. Seeds germinate in 2-3 weeks, then the film is removed, and the box is placed in a lighted place, usually on a windowsill on the sunny side.

As soon as the sprouts are sufficiently strengthened and gain strength, they should no longer be covered.

During the germination of linden seeds, the ambient air temperature should not be below 20C. Seedlings should receive enough sunlight to accelerate the process of photosynthesis.

Measures for the care of linden seedlings consist in the obligatory loosening of the soil layer and timely watering. After 3 weeks from the moment of emergence of seedlings, they must be thinned out in order to get rid of weak shoots.

Then all the resulting plants are planted in separate pots. This contributes to their further strengthening and growth. For this event, soil similar in composition to the one in which the seeds germinated is needed.

When transplanting seedlings, you need to carefully handle the root system, as it is still quite weak and can be damaged.

With the onset of real heat, which happens during the period of May, the seedlings obtained earlier are planted in an open area.

The tree belongs to the Linden family, referred to as large-leaved linden (Tilia platyphyllos) or broad-leaved. The popular name is lutoshka or washcloth.
