Thuja Green giant grows naturally in North and Northeast America (Canada, USA). It reaches a height of five to ten meters but is slow in growth and longevity. The Indians call it “iron” wood for its strong, rot-resistant wood. Thuja Green giant brought from the American continent is usually called western. The pyramidal shape of the western Thuja Green giant was brought to Europe in the sixteenth century. At the end of the eighteenth century, Thuja Green giant began to be grown in the southern regions of Russia. It becomes part of the park landscape in Crimea, in the Caucasus.

In the East, the eastern Thuja Green giant is grown, which is cultivated as an ornamental and medicinal plant. In nature, it can be found on mountain slopes in China, Japan and Korea. Tuyu is also called the “tree of life”. On the one hand, this name is attributed to the French king. On the other hand, this is how it is called in the East, where it is considered a cult tree. In Central Asia, it was planted in holy places, near mosques. Eastern healers use Thuja Green giant to prepare medicines.

Types of room Thuja Green giant

The genus tui is divided into six main types, in each of which many new varieties have been bred. In indoor floriculture, two types are used: western Thuja Green giant and eastern Thuja Green giant.

There are a number of differences between them, which determine the belonging to the species. Previously, it was believed that the western Thuja Green giant has a pyramidal shape, and the eastern Thuja Green giant is closer to the form of a bush. Now, in each species, plants of different shapes have been bred:

  • pyramidal;
  • spherical;
  • dwarf and others.

Also, the color of the leaves of modern Thuja Green giant can be dark green, yellowish and even bluish. Therefore, it is necessary to be able to distinguish between the east and west by the structure of branches, leaves and the shape of the cones. Modern botany classifies the eastern, which is also called biota, to a separate genus – the eastern flatworm.

Below is a table that highlights the similarities and differences between western and eastern Thuja Green giant, as we will continue to call them.

The main signs Thuja Green giant Western Arborvitae
Branches The plant is single-stemmed, and the branches are turned in different directions relative to the trunk. This gives the plant splendor. Branches at the base branch out into several trunks, growing parallel to the main trunk. The branches are raised up.
Escapes Shoots are short, and their ends are bent upward. Light brown shoots are flat, forming a system of plates located radially relative to the trunk.

Home care

In order for a Thuja Green giant in an apartment to grow into a beautiful tree, certain conditions must be created for it.

Lighting

Thuja Green giant, which came to us from cool places in North America, does not like the hot direct rays of the sun. From them, burns form on its leaves, the needles begin to turn yellow. Thuja Green Giant is considered a shade-tolerant tree. But the amount of light should be sufficient so that the branches do not stretch out. The best place in the apartment is a short distance from the window, especially the southern one. On the northern windows, you can put the pot on the windowsill.

Temperature

To create comfortable conditions for Thuja Green giant, it is necessary to provide it with the required temperature depending on the season. In summer, the plant feels great in a temperature range of twenty to thirty degrees. You can put a pot with a tree in the apartment, take it out to the balcony or into the garden.

Important! In the fresh air, the plant needs to provide a light shade.

But in order to keep the Thuja Green giant in a pot in winter, you need to take care of choosing a suitable place. Thuja Green giant very badly tolerates dry and hot air of apartments. In the cold season, the optimum temperature for a plant is no higher than fifteen degrees. If there is a glazed balcony, then the Thuja Green giant is left to winter on it. She can withstand a slight frost, but in frosts you need to protect the roots from hypothermia. To do this, the pot can be placed on a wooden or cardboard substrate, and the pot can be additionally wrapped. Thuja Green giant also does not tolerate drafts.

Watering and humidity

Thuja Green giant tolerates dry air and soil well. Therefore, the plant does not require frequent watering, but still it is impossible to allow the soil to dry out, especially during the growing season and after transplantation. In hot weather, the Thuja Green giant is watered once or twice a week, depending on the air temperature. In winter, reduce the frequency and amount of water when watering. It is necessary to slightly moisten the ground once or twice a month at a positive air temperature. If the air temperature approaches zero in the room (on the balcony) where there is a pot with a plant, then watering is stopped until the temperature rises. Water for irrigation should be warm (room temperature), separated.

Important! Avoid waterlogging of the soil! It is harmful to Thuja Green giant.

Thuja Green giant does not need additional air humidification. But in hot weather, it is recommended to periodically spray the Thuja Green giant to remove dust.

The soil

The soil for room Thuja Green giant should be loose, air and moisture permeable. In order for the indoor Thuja Green giant to grow well, turn green and not get sick, it is necessary to select the soil in accordance with the age of the plant. Young plants are planted in the following earthen mixture:

  • coniferous land (2 hours);
  • sheet (4 hours);
  • coarse river sand (1 hour).

When the plant grows up, and annual transplants are no longer required, it is necessary to plant it in soil composed of peat and sod land in equal quantities with the addition of river sand in a half dose. For an adult plant, you can purchase an earthen mixture for conifers in stores, which is also suitable for room Thuja Green giant.

Pot selection

A pot for a Thuja Green giant growing indoors is selected taking into account the size of the root system. The root of the Thuja Green giant grows down, so the pot is chosen deep. For large plants, the pot must be stable. When choosing a container for transplanting, its diameter must be increased by a couple of centimeters. And a few centimeters are added to the length of the root for drainage. Also, the bottom of the pan should have good drainage holes.

If the Thuja Green giant will winter in a room where there may be low temperatures, it is necessary to carefully approach the choice of material from which the pot is made. The material should not be porous, absorb water. The pot must be frost-resistant and protect the roots from hypothermia. If the Thuja Green giant stands in a room where the temperature does not drop below ten degrees Celsius, then you can not be so picky about the choice of pot material.

Transfer

Thuja Green giant room transplant is carried out in the spring. Young plants are replanted annually, increasing the pot by a couple of centimeters in diameter. Adult Thuja Green giant are transplanted every few years. When transplanting, the following rules must be observed:

  • lay a drainage layer on the bottom of the pot;
  • water the Thuja Green giant well before and after transplanting;
  • transfer to be carried out by the transshipment method;
  • large plants are cut off before transplanting;
  • the root collar can be slightly deepened to form additional roots.

Pruning

Pruning room Thuja Green giant, which is carried out in the spring, can be divided into preventive and decorative. Dry twigs are cut prophylactically. Thuja Green giant can be cut, pinched shoots to form a crown in the form of a pyramid or a ball.

Topdressing

Indoor Thuja Green giant does not require frequent feeding. It is enough to apply fertilizers once a month. You just need to take into account that in the spring it is advisable to feed it with fertilizers with high nitrogen content, and in the summer – potash and phosphorus fertilizers alternate.

In autumn and winter, Thuja Green giant does not need feeding.

Reproduction foThuja Green giant

Like most houseplants, Thuja Green giant propagates by seeds and cuttings. Seed propagation requires patience, compliance with all germination conditions. It should be borne in mind that when propagated by seeds, the varietal characteristics of the plant are not always preserved.

Seed propagation

The seeds are obtained from the cones of an adult bush. Ripe buds are cut and placed in a warm, dark place. When they start to crack, the seeds can be removed. Before planting, they are wrapped in a damp cloth and kept for 24 hours, not allowing the napkin to dry out.

It is necessary to take soil for young plants, pour it into a box or other container for germination. Seeds are sown on the soil surface, sprinkled with sawdust or sand on top. The container with the sown seeds is placed in a warm place (20 – 23 degrees Celsius) with diffused light. Seeds sprout in a month and a half. It will take three to five years to grow a mature plant. Therefore, seed propagation is rarely used, preferring to grow a new tree from cuttings.

Propagation by cuttings

For reproduction, side branches about ten centimeters long are used. Cut off a twig with a “heel” – part of a stiff shoot. The cut is treated with Kornevin and planted in an earthen mixture. Planting depth is two to three centimeters. A stalk of a room Thuja Green giant does not need watering. The container is placed in a warm place and the soil is periodically sprayed. After rooting, which is manifested in the growth of new leaves, the pot is transferred to a place with access to fresh air. Soon, you can transplant a new plant to a permanent place.

Thuja Green giant diseases and pests

Problems in growing room Thuja Green giant are divided into care errors, fungal diseases and the appearance of pests.

Among the main problems is the yellowing of the leaves. The reason usually lies in sunburn received from direct sunlight. You should also pay attention to the root collar. If it protrudes above the ground or is heavily sprinkled, then the leaves of the Thuja Green giant also turn yellow.

Important! If the Thuja Green giant turns yellow in winter, this is not dangerous and is a natural process. And here you should pay attention to the yellowness of the branches in spring and summer and take measures to eliminate the problem.

Among the diseases of room Thuja Green giant, the most common are fungal diseases, cytosporosis, fusarium. Cytosporosis affects the bark of the plant, forming black areas on it. Gradually, the fungus infects the inner layers of the wood, which leads to the death of Thuja Green giant without timely treatment.

Fusarium manifests itself in the reddish-red color of the needles, and it’s subsequent wilting. The roots and nutritional system of the plant are also affected, which often leads to its death. The plant is treated with Bordeaux liquid, kartocide. Processing is carried out every two weeks until the plant is completely healed.

Among pests, Thuja Green giant is attacked by aphids, scale insects, bark beetles. Aphids settle on needles, sucking out the juice, which leads to yellowing of the twigs. The scale insect lives in the bark and seeds of the Thuja Green giant. If holes are visible in the bark, this means that the bark beetle has settled, destroying the plant from the inside. For pest control, insecticides are used according to the attached instructions.

Conclusion

Indoor Thuja Green giant not only serves as a decoration for the room but also purifies the air with phytoncides. Its aroma is soothing and promotes good sleep. Broths of pine needles are used to combat certain diseases. In winter, Thuja Green giant can be decorated instead of a Christmas tree.
