Thuja folded is one of the most common evergreen conifers in landscape design. She represents the Cypress family, a kind of gymnosperms, genus Tui. The tree, which originates from East Asia and North America, is actively used by landscape designers in the creation of hedges and other compositions. Folded thuja has many features, so before buying a plant, it is important to read its description and photo, find out all the rules for planting and maintenance.

General description of folded thuja

Thuja folded is an evergreen tree or shrub with a dense crown formed by shoots branched in one cavity. Under natural conditions, a culture in adulthood can reach up to 60 m in height with a diameter of 2.5 - 3 m. From above, the trunk of the ephedra is covered with a fibrous crown of a reddish-brown hue. Thanks to this feature, the folded thuja was given another, unofficial name - "red cedar". The plant has a fairly dense pyramidal crown and rather narrow leaves (each such needles reach no more than 1 mm in width). With age, they begin to lay on top of each other and acquire a shiny gloss on the front side. On the back of the needles, you can see pronounced white stripes.

The fruits of the folded thuja are cones that reach about 12 cm in length and have an oval-oblong shape. One thuja cone usually contains two flat seeds with two wings.

Folded thuja varieties

Thuja folded has many varieties, each of which differs in its appearance and decorative qualities. Below are the most common types of wood with photos and descriptions.

Kager's Beauty

Thuja folded Kagers Beauty is an evergreen conifer of the Cypress family with loose, spreading needles. In adulthood, the ephedra reaches no more than 0.5 m in height with a diameter of 0.6 m. It is a tree with a superficial root system, especially sensitive to soil compaction and scaly needles of a gray-green color. It prefers to grow in a well-lit area or in a slightly shaded place, demanding on the quality of the soil: it must be fertile and well-moisturized soil. The folded thuja Kagers Beauty finds its best color in sunny areas, while the shade gives the tree a darker shade. Thuja varieties Kagers Beauty tolerates drafts and strong winds well, but is very sensitive to dry weather, and especially needs frequent watering during dry periods.

Application in landscape design

Many varieties of folded thuja (Kankan, Kagers, Western) are used to decorate garden and summer cottages. Almost all plant varieties adapt well to shearing and shaping, which allows the tree to be quickly shaped to the desired shape. Most tree varieties are undemanding to maintain and are able to maintain their rich green color throughout the year. Thanks to such rich decorative properties, folded thuja has a fairly wide range of applications: it is used to design single and group plantings, create hedges, as well as to create landscape compositions such as rock gardens, rockeries, mixborders, as well as in container versions.

Single plantings of folded thuja look good near water or on lawns, especially in combination with various types of other ornamental plants. Some varieties of coniferous plants have an unusual crown shape and the aroma of needles, which makes the folded plant an indispensable element in the landscape gardening of the garden and suburban area.

Breeding features

In order to grow as many healthy seedlings of thuja folded giant as possible, it is best to get the planting material yourself. The tree can propagate in two ways: seed and cuttings.

If the priority is not to preserve the plant variety, then you can choose the seed propagation method. To do this, at the end of summer, you need to collect the seeds of folded thuja and immediately plant them on light and moist soil. In winter, the crops must be covered with foil. If sowing is carried out in the spring, then the seeds must first go through the process of monthly stratification.

In order for a new folded thuja plant to retain all the decorative properties of the mother tree, propagation is best done using green or semi-lignified cuttings. The most qualitative process of root formation takes place with the help of planting material, which was harvested at the end of July.

Attention! It is necessary to break off the cuttings from the branch of the folded thuja in such a way that a "heel" remains on them.

It is best to root cut twigs in the garden, under the crown of a tree.

  1. First you need to dig up the planting area and add peat.
  2. Pour a layer of sand on top, which will prevent damping off.
  3. Plant folded thuja branches previously soaked in Epin or Kornevin at an angle to the depth of a layer of sand.
  4. Top with a jar or bottle.

It is allowed to transfer the folded thuja to a permanent planting site not earlier than next spring.

Important! Thuja can be propagated all year round. Only those cuttings that were obtained in winter need to be germinated indoors.

Planting and leaving

For planting folded thuja, it is best to choose a well-drained soil with a high level of moisture: dry soil can significantly slow down the growth of a tree, and its crown will gradually thin out.

In order for the folded thuja to have time to get stronger by winter, it is best to plant the plant in the spring. The planting hole should be about one meter deep with a drainage layer at the bottom. Do not deepen the root collar of the plant much when planting.

When planting a folded thuja for a hedge, remember the distance between the conifers: it should be within three meters. Forming an alley, the space between plants is increased to five to six meters.

In the first month after planting, the plant needs regular watering: once every seven days, and in areas with an arid climate - twice a week. One folded thuja seedling accounts for more than 10 liters of water. In the evening, you can spray the crown of the plant.

The culture adapts well to transplantation. It is best to hold an event for young seedlings in the spring, and for adult plants - at any time of the year.

Growing features

Mature specimens of folded thuja do not need special conditions of detention. Particular attention should be paid to young seedlings, providing them with proper care. In the spring, folded thuja especially needs feeding. Nitroammophosphate and any set of complex fertilizers are best suited.

Important! It is necessary to apply top dressing to the soil only when the snow has completely melted.

In the spring, pruning is carried out, removing all dried up and unnecessary branches, and, if desired, form the necessary crown shape. It is equally important to mulch around the ephedra with peat, bark and needles. This helps to maintain soil moisture as well as protect against weeds.

Adult plants tolerate winter well (folded thuja can withstand temperatures below 30 degrees of frost), however, it is better for young seedlings to provide reliable shelter from frost and snow piles.

Pests and diseases

Like most conifers, folded thuja has a strong natural immunity, however, in unfavorable conditions, the risk of infection of the tree can increase several times. The most common diseases of folded thuja are:

  1. Brown shute - often the disease manifests itself in the spring, after the snow thaws. On the bright green needles of the plant, yellow, red-brown or black needles begin to appear. The affected areas of the tree begin to cover the oblong fruiting bodies of pathogenic fungi. Having found the first symptoms of the disease, it is necessary to begin immediate treatment: cut and burn all damaged branches, and the ephedra itself must be sprayed with a 2% solution of copper sulfate or a special drug - Fundazol.
  2. Gray rot - often affects young ephedra seedlings. This disease develops due to too dense planting, lack of ventilation and low light. Thuja shoots become brownish. At the initial stage of the disease, spraying folded thuja with copper sulfate will help save the plant.
  3. Fusarium is a fungal disease of thuja caused by pathogenic bacteria of the genus Fusarium. This is one of the most insidious coniferous infections that begins at the roots of the tree, making it impossible to see the first signs of the disease. After yellowing and complete drying, there is no point in treating the tree. That is why it is very important to carry out the prevention of thuja: before planting, spray with fungicides and prevent waterlogging of the soil in the territory. If in a group planting one thuja seedling died from fusarium, the remaining trees need to be watered under the root with a Fundazol solution, however, it should be understood that such protection cannot give a 100% guarantee.
  4. Stem rot - often this infection affects thuja with mechanical damage to the bark and wood. Getting into the formed cracks, moisture begins to turn injured places into rotting breeding grounds of parasitic microflora. To avoid the disease of folded thuja, it is important to treat damaged areas of the bark in time with garden varnish or special preparations.
  5. Phytophthora - the roots of a plant affected by this infection gradually begin to rot, the bark at the bottom of the trunk gradually softens, its surface becomes covered with pinkish and dirty white blotches. The wood under the affected areas of the bark begins to turn brown, a characteristic smell of rot appears, the needles grow dull and soon completely crumble. If signs of phytophthora are found, the thuja should be immediately treated with a preparation containing copper, however, the best option would be to dispose of the diseased specimen: this is guaranteed to prevent the spread of the disease to other seedlings.

Conclusion

Thuja folded is an evergreen coniferous plant, which is actively used to decorate garden and summer cottages. Ephedra has many varieties, each of which is characterized by its own unique decorative properties. The plant is unpretentious to care for and is able to maintain its green color throughout the year. However, having decided to purchase a folded thuja, it is extremely important to observe agricultural techniques, then the thuja will delight with its beautiful appearance all year round.
