Thuja in Siberia appeared in the second half of the last century. Scientists Pashkevich and Osipov brought it there and were able to grow it on their plots. The homeland of thuja is the southern part of the eastern North American forests. But some species grow on the northern outskirts of the United States and Canada. Often they can be seen even on marshy
cold soils. It was from these plants that seedlings were taken for cultivation in a cold Siberian climate. Western thuja in Siberia took root pretty well. This plant is frost resistant. Thuja is a long-livers whose life span can reach 150 years. The tree is undemanding to the quality of the soil and perfectly transfers the shearing of the crown. Often the western one is used to create
hedges.Thuja western is either a monoecious tree reaching 20 meters in height, or, less commonly, a shrub. The crown is dense, compact. The young plant has a conical shape, with age the branches grow and the thuja takes the form of an egg, lowering the branches to the ground. The bark of young animals is red-brown, smooth and elastic, later acquires a light brown color and is easily separated by ribbons. Thuja western has bright green shiny needles in summer, in winter it becomes brown-green. Her life span is 3 years. Then the needles fall off along with small branches during the “tree fall”.
In order for the thuja in Siberia to take root, an amateur gardener will have to first
make some effort. First, you need to purchase a viable seedling. The plant must be strong, then there is a chance that the thuja will grow. The price of a seedling depends on the degree of its development. Secondly, the landing must be done correctly. Plants should be planted no closer than 0.5 meters to each other. Planting depth - from half a meter to 80 cm. It depends on the size of the lump of earth on the seedling and on the diameter and height of the crown. In any case, the root neck should be at ground level. Drainage is done on underlying clay or on pipes (in a swamp) with a thickness of 15 to 25 cm.
In the first month after planting, thuja must be watered once a week (10 liters per plant) and, in the absence of rain, sprinkle, because the plant loves moisture and thins on dry soils. Loosen the soil near the trunk shallow - up to 10 cm,
because thuja has a superficial root system. It is advisable to cover the ground with small chips or peat (up to 7 centimeters thick), since young thuja in Siberia can freeze during the cold season. And in the first winter it is better to arrange shelter for young animals. The needles of young plants must be protected from sunburn in spring and summer, covering branches with paper or lapnik. In spring, it is necessary to remove all dry shoots on the plant.
Many amateur gardeners acquire the western one to create various forms of trees on the site - a kind of sculpture. Mowing the plant can only be carried out on an adult plant at 1/3 of the shoot length, and therefore, for example, spherical thuja can be transformed only at the age of 10-15 years. Adult plants do not require such careful care. Approximately 1 time in 2 years, thuja western is fed. In dry periods, the soil near the trunk is watered, mulched and loosened. Thuja is resistant to harmful atmospheric emissions, it can be grown even near industrial facilities. It goes well in plantings with spruce, larch and cypress.
