The highlight of the garden: thuja with a spherical crown shape. Thuja western Thuja western dwarf

Columnar thuja is one of the varieties of western thuja used in landscape design of both public recreational areas and household plots.

Like all thuja, it is well adapted to different conditions growth.

Characteristic

Among the main characteristics of thuja should be noted:

The growth of an adult tree can reach 30 meters. At the same time, it grows for about 100 years. It adds up to 20 cm in height per year. The diameter reaches 1.5 meters.
It is highly resistant to low temperatures, thanks to which in the winter season you can not cover. But at the same time in very hot weather requires additional watering.
It is highly resistant to pests and diseases.

Note: when planting a thuja hedge on the site, not only a beautiful emerald tone appears for other plants various shades, but also excellent protection against gusts of wind, dusty and smoky clouds from the road.

Suitable for haircut. At the same time, a haircut from above stimulates growth in width, and from the sides - in height.

Landing and care

As a rule, thuja are able to adapt to any growing conditions.

But in order for the trees to grow and develop effectively, they need additional care, especially when it comes to young seedlings:

watering once a week;
in the evening at night, seedlings cover from coolness;
regular feeding, mixtures for coniferous species for fertilizer can be bought in specialized stores;
loosening the soil should be done from time to time, in parallel, mulching should be done - cover the ground around the tree with peat, dry grass or sawdust.

Such a layer will not only retain moisture for a longer period of time, but also gradually feed the tree through the root system. When cold weather approaches, the layer will also protect the roots close to the surface from freezing.

Caring for mature plants is also quite simple:

in prolonged dry weather, the trees are watered twice a week and sprayed. This way, additional moistening of the needles is obtained twice a day and at the same time dust and dirt are washed off from the crown. Need to do it early morning and in the evening with twilight;
fertilizer is carried out in the spring;
loosening the earth should also be carried out regularly.

For columnar thuja, animal urine is detrimental. Therefore, it is necessary to provide protection from animals.

Rules for breeding at home

As a rule, amateur gardeners.

Slightly stiff cuttings are picked up, separating them from the branch by tearing, but not by cutting. The cultivation of future seedlings has its own characteristics, as well as their planting.

For germination, the cuttings are placed in a warm room.
The cuttings must be woody.
First of all, after collecting the cuttings, future seedlings are placed in water, then after 2 hours they are placed in the ground.
The soil should consist of peat, soddy soil and sand. River sand is best.
Landing is done in the autumn season, long before the onset of cold weather.

To create a dense, seedlings are planted in an even straight row at a distance of 0.5 meters from each other.
The first pruning of seedlings is carried out immediately after planting. In this case, the height is aligned with the lowest seedling in the entire row. If the planting was at the beginning of autumn, then the plant is cut off next spring.
The first time can be spent with ordinary secateurs. But the older the tree becomes and the thicker its crown, the more powerful the tool is needed. For example, electric scissors.
When purchasing a thuja dug out of the ground, pay attention to the clod of earth resting on the root system. It should not crumble, be large in size. When the pit is wide, it should be wider than the earthen clod. The depth should be 80 cm.
With age, the thuja dries out a little and crumbles from below. To hide this annoying flaw, you can plant low-growing densely growing shrubs (for example, quince) in front.
A way to protect thuja from dog urine: you can surround the plants with a net or thorny shrubs (for example, barberry).
For the winter, it is recommended to fix the top of the tree with a rope, as it can deform and spoil the whole appearance of the plant.

What a large columnar thuja looks like and how high it can be, see the following video:

The pyramidal thuja is a representative of the western variety of the plant, when grown in nature, in northeast America, it reaches a height of 30 meters, but cultivated varieties grow only up to 12 meters.

The columnar, as it is also called, thuja, has a crown color with a red tint, sometimes a brown-gray color. Old trees are characterized by flaking of the crown, and young representatives have a cone-shaped or pyramidal shape. In trees, the needles grow densely on the shoots and last for about 2-3 years, have a saturated summer green color, and by winter a brownish tint appears.

Tui pyramidal retain vitality over 100 years, although there are cases of a longer existence of trees. A very viable tree-like plant, it is characterized by slow growth, it develops better on loamy soils, but does not show special demands on the soil.

If growth occurs on depleted soils, then the plant is distinguished by the yellowish color of the needles. It tolerates dry years quite well, although it loves moist soil and places with high humidity atmosphere. After 70 years of life, the lower branches begin to die off and fall off, which makes the thuja less beautiful. It grows well in all latitudes of Russia.

In spite of high growth, perfectly resists wind loads, endures smoke and gas clouds for a long time, to create original form thuja is cut, the tree does not deteriorate from this, a haircut does not affect further growth, as well as a transplant.

Breed features

The problem of thuja is often the abundance of cones that acquire a chocolate color by the beginning of autumn, from which the tree looks brown-green. After they fall off in a year, the crown becomes loose. Summer drought can affect the formation of such seeds. Sometimes it is found that some of the legs of the thuja have turned brown and dried up.

You should not be afraid of this if the process does not affect more than a quarter of the crown, this phenomenon refers to the natural change of needles. Although the thuja is classified as an evergreen tree, the needles change every 3-5 years.

tree planting conditions

For effective growth and development should comply with certain conditions:

thuja is propagated by seeds, which require a certificate for effective growth, sometimes cuttings are used with green shoots;
it is advisable to plant in moist soil, but in the absence of a tree, it will also cope with dry “living” conditions;
copes with shading, but sunlight is desirable;
the critical temperature below which the thuja does not withstand is the thermometer reading below 36ºС;
when planting, the roots must be buried at least 80 cm;
in the process of growth does not emit toxic substances into the environment for humans and animals.

Growth Features

After landing in suitable conditions, observe development rules:

soil acidity should be within the range of 5.3–7;
thuja develops most effectively with precipitation in the range of 900–1500 mm per year;
when growing, it is recommended not to exceed a density per hectare of more than 3 thousand specimens;
thuja is undemanding to the land of growth, but prefers fertile soils or their averages;
the tree does not have resistance to soil salinity, thuja requires highly nitrogenous, calcareous soils.

Tui seeds are formed in pods of two, maturation is achieved in autumn period. The cultivation of the seedling takes place within 5 years, the soil of the local climate prepares the plant for the harsh conditions of Russia. It is advisable to choose sunny place and nutrient soil.

Seeds are sown in the ground in spring no more than 5 cm deep. The landing site is covered with a small layer of sawdust from a coniferous tree. Although young trees love the sun, the seedlings that break through are very sensitive to it, so it is not recommended to expose them to open rays, the seedling sites should be shaded.

Watering and loosening of the soil is regularly recommended, it is necessary to fertilize with slurry diluted in a ratio of 1:20, at which young seedlings grow very well. For cuttings, shoots are taken from shoots at the age of 2–3 years. Urgent planting allows the use of a process of one year, but at the same time it needs to be deepened with a piece of the old trunk so that the cutting takes root faster.

Before planting, the processes are necessarily treated with heteroauxin. For better growth, a mixture of turf and peat is prepared in a 1: 1 ratio. Saplings - cuttings are buried in the soil to a depth of at least 1.7–2.6 cm. Greenhouses are considered the best place for growing seedlings, where the necessary conditions are created.

Thuja pyramidal care

Under normal conditions, watering the thuja is recommended. The description of the breed speaks of its endurance of an arid climate, but frequent rains have a beneficial effect on the correct formation of a pyramidal crown. If the thuja is not ennobled, then the decorative qualities of the tree do not appear, the plant loses its beauty.

Regular watering prevents the tree from getting enhanced feeding nutrient solutions, which lead to the abundant appearance of cones with seeds on the crown. Such a tree acquires asymmetrical shapes and beauty, so cones and dead needles must be removed every spring.

If required, thuja can be transplanted, as the tree easily tolerates this procedure. Changing the place does not cause difficulties for the gardener, since the rhizomes of the tree are collected in a compact tuber. Therefore, if there is any doubt about wrong place landing, then it can be changed. Some varieties of thuja are tied with ropes for the winter so that the snow does not harm the shape of the tree, other varieties are forced to be in such a bunch all the time.

Regularly, but in moderation, thuja should be fertilized, you need to start again in early spring when it snows. During this period, nitrogen fertilizing is introduced, the next stage of fertilization occurs in June, potash solutions are used. Tree specimens growing on depleted land are supported by fertilizing with phosphorus solutions.

The description of the properties of the tree says that the crown is exposed to a pest called false scabies. Gardeners successfully fight this problem with the use of karbofos and aktelik in early spring. They spray the crown of the thuja before the leaves bloom and two more times in the summer and once in the fall. The same drug destroys aphids on the branches and needles of a tree. Varieties of decorative pyramidal thuja

Several types of trees grow in the natural pool:

eastern;
Japanese;
Korean;
folded;
western.

Eastern thuja characterized by a fan shape of branches, brought from China, hence its inability to withstand long and severe frosts. AT middle lane the breed is planted only in the shade of nearby tall trees; it grows and develops better in the southern regions of Russia. According to its medicinal indicators, it is used to alleviate many diseases.

Japanese pyramidal thuja comes from a Japanese island, where it grows in mountain coniferous-deciduous forests, at an altitude of up to 1700 m above the sea. It has an original needle color - spotted below, covered with a green layer from above. It grows up to 18 meters in height and is characterized by a resinous-spruce smell. It is unpretentious, steadfastly withstands strong and prolonged frosts and takes root in the regions of the Arctic. For a long time withstands dry anhydrous climate, grown in all latitudes. Poorly tolerates the polluted atmosphere of cities, requires clean air.

Thuja Korean more like a shrub in its growth rates, originally from the forest areas of the peninsula of Korea, where it is not very common. It has a sprawling large crown, which is distinguished by its original color, one tree can different places have rich green tones and silvery colors. In Russia, it is grown in the southern regions, as it does not tolerate cold snaps at all.

Folded thuja also does not like the manifestations of cold, but its peculiarity lies in the fact that frost-bitten shoots restore their properties after thawing. Such a tree grows up to a height of a twenty-story building, some specimens reach a thickness of two meters. It has a pyramidal shape of the crown, emits a pleasant specific smell. Native to the Canadian West Coast.

western thuja

The most common species is the western thuja, which is in demand by gardeners because of its ability to withstand severe frosts and undemanding growing conditions. This type of thuja has the most a large number of varieties and forms, the life period is 100 years or more. Among gardeners, amateurs are most used for planting dwarf, weeping, variegated, miniature species of western arborvitae.

Suitable for landing in various regions of Russia, except for our country, the countries of Western Europe are engaged in its breeding. Most varieties of western arborvitae do not lose their crown shape even when grown in full shade. Prefers light loamy soils when planted in sandy soils, it requires constant feeding. Resistantly tolerates the gas content of urban air. Thuja is very much in demand for creating decorative green fences and living fences.

Planting and caring for a species of western thuja

It is recommended to plant in a place protected from the wind. For the effective cultivation of seedlings, a mixture of soddy soil, peat and sand should be prepared in a ratio of 2: 1: 1. It is allowed to add to this composition 500 grams of nitroammophosphate for planting one tree. When planting, it is recommended to leave the root collar uncovered with soil.

After landing, ensure good watering in the amount of ten liters daily per tree during sprinkling. If it turned out to be a dry and hot summer, then the amount of moisture is increased to 20 liters and watering is carried out only in the morning and evening, the tree is left to rest during the daytime. If the thuja does not receive enough moisture, then its crown is characterized by the formation of cones with seeds, becomes ugly, loses its elastic shape and the decorative effect of the tree is lost.

If fertilizers were used when planting a tree, then top dressing is carried out only for the next year. A plant planted without application minerals, fed in the first year in early spring and twice during summer period. Young seedlings should be protected from direct sunlight. to prevent burns.

Pyramidal thuja Dense according to the description has a narrow crown in the form of a cone, grows up to 10 meters in height. Dense short shoots branch out and fit tightly in the crown to each other. The tree has needles in the form of green scales with a slight shiny effect. The breed withstands the winter climate well, it is recommended as a single tree, and for planting in a hedge group.

Western Equal thuja grows to a height of 15 meters. The shape of the crown is similar to cypress, numerous branches contain densely pressed needles, which are directed slightly downward. Bred in Germany, it is characterized by rapid growth and, unlike other species, retains its green color even in winter.

Western thuja Brabant grows up to 15–20 meters, is characterized by sprawling coniferous crown up to 4 meters in diameter, smoothly turning into a cone. The scaly needles keep juicy color in winter. The tree is undemanding to soil conditions, grows well in dry and wet lands. Tolerates transplantation and shearing, quite unpretentious.

A variety of western thuja Vervain distinguished by a refined beautiful crown, representing a narrow cone. Numerous thin branches form a soft and dense crown of yellow and green flowers in light shades. The variety was bred in Belgium, preferably planted in alleys near houses.

Variety Malonyan, grown in Slovakia, has an narrow-leaved form, densely spaced numerous shoots are collected in a sharp apex form with shiny needles with a glandular tint. Tolerates frost very well long time.

A variety of western thuja Smaragd has a standard shape in the form of a pyramid, but of a more squat appearance, a low tree grows up to 4-5 meters in height. Grow as a single tree or in a group of the same type of trees to create a decorative hedge or planting along the alley. If a multi-row landings are planned, then Smaragd is well suited for creating a background.

Variety Holmstrup is a shrub that rises up to 4 meters with a crown up to 1 m in diameter. The shape of the tree resembles a cone. The branches have a reddish bark or a grayish tint and thick, scaly green needles. Slow growth is noted, only about 10 centimeters per year, grows very well in the shade, develops in dry and moist soil. Easily tolerates frost.

Thuja is very popular, growing in private courtyards and public squares allows you to create a beautiful ensemble to decorate the area.

Thuja pyramidal, or thuja columnar, or thuja cone is a variety of western thuja and can reach 30 m in height, but in culture it often does not exceed 10 - 12 m.

The crown of the trunk is reddish or grayish-brown, exfoliating in mature trees. In young trees, it is pyramidal, later columnar.

The needles of the thuja fit snugly to the shoot, in summer it is dark green, in winter it most often becomes brownish-green. It remains on the tree for 2-3 years. Under natural conditions, thuja grows in the zone coniferous forests in eastern North America.

The life expectancy of thuja is 100 years or more. By old age, it loses the lower branches and becomes less decorative. Grows slowly. Thuja is shade-tolerant, undemanding to the soil, but grows better on fresh fertile loams. On poor soils, thuja needles acquire a yellowish tint, but do not lose their decorative effect. It tolerates drought, although it prefers places with sufficient moisture in the soil and air. Thuja is quite winter-hardy up to the latitude of St. Petersburg in the north and Yekaterinburg in the east.

Wind resistant. Among conifers, it is considered one of the most resistant to smoke and gas. Thuja columnar perfectly tolerates a haircut and is suitable for creating dense hedges. It tolerates transplant well.
Tui have great polymorphism. Most decorative forms of thuja are more demanding on environmental conditions than the main species.

Usually, columnar or pyramidal forms are offered for landscaping:

Columna, Douglasii, Pyramidalis, Fastigiata, Brabant, Malonyana 6-10 m high and

Smaragd, Holmstrup, Rosenthallii, Wagneriana, 3-4 m tall.

They are most often used to create green hedges, while their size and features must be taken into account accordingly.

Forms with several tops, multi-stemmed (Fastigiata, Malonyana, Wagneriana) before the onset of winter must be slightly pulled together with twine to prevent breaking the crown with heavy wet snow, and large specimens often even need to be fixed with a coupler throughout the year.

Under the conditions of Moscow, Smaragd and Brabant are less winter-hardy, although Smaragd is interesting for retaining its emerald green color in winter, while most green forms become copper-brown to one degree or another (in spring, the color is restored, provided there is no winter burn). Another "brown" problem - often thuja is spoiled by an abundance of cones, which turn brown at the end of summer, respectively, the plant looks green-brown, and in next year when they fall, the crown becomes loose. This usually happens after a hot, dry summer, perhaps you should take comfort in the fact that this year your pet has “successful life”, which affected the formation of seeds. Gardeners are frightened by discovering brown shrunken paws-twigs. If this happens inside the crown and does not affect more than a quarter of its volume, and young shoots last year they don’t look suffering - it’s okay, this is a natural process of “coniferous fall” (which happens like a “branch fall” in arborvitae), since arborvitae are evergreen conifers, but the needles live 3-7 years.

Thuja western smaragd (Thuja occidentalis smaragd) - the form is pyramidal, but rather squat, its height reaches an average of 4-5 meters. It is distinguished by a moderate growth rate: in 10 years it grows by only two meters. Thuja smaragd is grown both alone and as part of group plantings, as a low decorative tree on sections or paths of park alleys. It is quite suitable for the formation of "hedges". In the so-called rock gardens, thuja smaragd is used to create a background.

The needles of this tree have a light green color, which does not change during the whole genus, neither in winter nor in summer. Tui smaragd plants are convenient in that they are completely undemanding to the composition of the soils on which they grow. But he does not at all refuse good soil: thuja smaragd trees take root best of all on soil abundantly enriched with humus. It is better if the place where they grow is well lit and well drained.
Thuja smaragd is also positively characterized by winter hardiness - that is, resistance to low temperatures. In case of heavy snow, it should be tied up, because abundant wet snow adhering to them can “destroy” a slender tree. After all, gardeners extremely appreciate precisely the thuja emerald precisely for its dense, regular crown.

Thuja is an evergreen coniferous plant belonging to the cypress family.

It is a tree or shrub with scale-like leaves and cracked bark. The crown is dense, dense, the branches grow in the same plane. In young specimens, the needles are needle-shaped. The color range of plants varies from pale green to red. There are many bicolor variegated varieties.

The title photo shows Thuja occidentalis "Golden Smaragd".

According to the shape of the crown, thuja is divided into:

columnar;
pyramidal;
wide-conical;

Suitable for spacious gardens and parks, solitary and group plantings and for vertical accents in powerful landscape compositions.

Landing

Tui older than 3 years, it is desirable to plant with a preserved lump, the dimensions of which should be approximately half the diameter of the crown. The size of the planting hole is usually 60 to 100 cm for plants up to 3 m in size.

Important: when planting in the ground, the root neck should be at ground level.

Therefore, initially it is necessary to plant so that the root collar is about 5 - 10 cm above ground level, because. after watering, the soil compacts and settles.

For planting, a soil mixture is taken from soddy or hardwood, peat and sand in a ratio of 2: 1: 1.

Be sure to use complex mineral supplements(nitroammophoska, etc.) - approximately 150 - 200 g per one landing pit. Pre-mixing them with the soil.

After planting, abundant watering is required - at least 2-3 buckets of water per pit for an adult seedling.

Tip: to improve the development of the root system and growth, it is advisable to use preparations such as Kornevin.

Care

In the first month after landing on permanent place thuja is watered 1 - 2 times a week for about 1 - 3 buckets per plant. If planting was carried out in the spring, then sprinkling of the crown is favorable for survival.

Attention: to prevent moisture loss, the near-stem circle should be mulched.

For this purpose, the bark of conifers, wet peat, leaf humus, garden compost, needles are used. In addition, the mulch, decomposing, serves as food for the roots, and also protects against freezing in winter.

Thuja has a shallow root system, therefore, soil moisture must be monitored. With insufficient watering or drying out, its crown may partially crumble and thin out. During the growth period, the plant is watered twice a week, 1.5 - 2 buckets of water per seedling.

In the process of care, it is necessary to loosen the soil to a depth of about 10 cm.

For a successful wintering, it is advisable to wrap the thuja with agrofiber. This will keep it from freezing. sunburn, and from fraying the crown with snow.

If the plant is planted in well-prepared soil, then 1 - 2 top dressings per year will be enough. In the spring, nitrogen-containing mineral fertilizers(ammonium and calcium nitrate, urea). At the end of summer - calcium and top dressing containing phosphorus (superphosphate, nitroammophoska)

Complex top dressings for long-acting coniferous plants work well, for example, Kemira and Osmokot.

It is important to know: if top dressing is made at planting, then the next top dressing should be carried out after 2 years.

reproduction

Thuja is propagated in two ways: generative (sowing seeds) or vegetative (cutting).

With the vegetative method of reproduction obtained young plant will fully retain the characteristics of the mother. The generative method is used for all types of conifers. However, its disadvantage is that it does not guarantee the preservation of the varietal qualities of some forms and varieties.

So, for example, when sowing the seeds of a columnar arborvitae, not all seedlings will inherit the columnar shape of the crown, but only a small part of them.

Growing from seeds

This method is quite laborious, but it allows you to get many strong beautiful plants.

In September, it is necessary to collect the bumps that have grown on the thuja and place them for some time in a warm, dry place. When they dry and open, the seeds must be collected, placed in a paper bag and put in the refrigerator until spring.

There they will go through the process of stratification. This will improve their germination, disease resistance. Before sowing, the seeds are recommended to soak for 12 hours in warm water or wet sand

Another option provides sowing seeds in autumn.

On the bed chosen for sowing, the soil must be loosened, sand and leaf humus should be added there. This will make the earth lighter and more breathable, thereby improving the development of the root system of future plants.

Sowing seeds should be carried out according to the scheme 8 cm by 20 cm (spacing), to a depth of 1 cm.

Cover the winter bed with burlap and spruce branches on top, which will need to be removed in the middle - end of March.

Seeds sown in autumn will germinate as soon as the earth warms up to 15 - 20 degrees.

Further care of the seedlings includes a one-time top dressing with a root growth stimulator, and periodic top dressing (1 time per month) with growth fertilizers, for example, Kemira or Agricol.

Do not forget to carry out preventive treatment against fungal diseases with fungicides.

Seedlings need constant moisture and light loosening. It will not be superfluous to mulch young plants with sawdust.

The growth of the first year will be about 8 cm. It will be possible to transplant thuja to a permanent place for 3-4 years.

How much do seedlings cost

The range of coniferous plants is quite wide and varied.

How to apply in landscape design and how many seedlings will be required

For landscaping the selected area, thujas act as:

hedges;
single trees;
group landings.

To form a hedge, take species such as Smaragd, Braband, Yellow Ribbon, Columna etc. Seedlings are planted at a distance of 0.5 - 0.8 m. The needles of these species do not turn brown in the winter season and do not change decorative look all year round.
Tui Excelsa, Aurescens suitable for group and single plantings, large-scale gardens and large parks, as these are tall plants. By the age of 10, they grow to 8 - 12 m, 3 - 4 m wide. They sit in groups at a distance of 5 - 8 m.

For small ones, undersized ones are suitable dwarf varieties: Aurea Pyramidalis (), Holmstrup ("Holmstrup"). By the age of 10, these species reach no more than 2–3 m and have a crown width of 0.5–0.8 m.

When landscaping suburban area, courtyard, city flower beds it is good to use several types of thuja at the same time, creating various compositions (photo). When planting, you should take into account the size of each plant in its adult form, reserving space for them to grow.

It is good to combine conifers of different crown shapes and needle colors (photo), choosing green and variegated, as well as two-color varieties.

Before starting work, it is good to draw up a diagram of the future flower bed, so that it is easier to visually imagine and plan the placement of plants and calculate their number and distances between them. An example would be the photo of the diagram below:

Due to its decorativeness, unpretentiousness and diversity, the pyramidal thuja has become an undoubted favorite in landscape design. It looks great both solo, and in, and in plantings along with other conifers, as well as together with annual and perennial deciduous plants.
