Coniferous trees and shrubs are widely used as a design option for landscape design. Tuya is no exception. On the basis of wild-growing large-sized trees, a large number of varieties with a variety of colors, shapes and heights were created. Tuya Kornik is the result of the work of Polish breeders. The founder was the thuja folded – a representative of the western variety of the Cypress family.
Description of thuja Kornik
From the wild-growing folded species of thuja, Kornik received not only a decorative habit, but also high frost resistance. The perennial evergreen thuja resists without losses the temperature drop in winter -350 C, spring frosts down to -60 C do not affect the development. This quality makes it possible to grow a tree in all climatic zones. And also the priority in choosing a variety is the shape of the plant and a slight increase during the seasonal growing season.
By the age of 15, the height of the thuja folded Kornik varies between 2,5-3 m. The duration of biological life is more than 200 years. Thuja grows in the form of a tree with a regular cone-shaped, dense crown. The folded thuja is shade-tolerant, resistant to strong winds. Thuja is undemanding to the composition of the soil, with an average degree of drought resistance.
The photo above shows thuja Kornik, its external description is as follows:
- The central trunk is of medium diameter, tapering towards the top. The bark is gray with a brown tint, the surface is rough with small longitudinal furrows.
- Skeletal branches are short, thick, strong. The arrangement to each other is compact, they grow at an angle of 450 relative to the trunk.
- Tops are flat, branched, vertically arranged. The crown is formed by peculiar folds, the young shoots of the thuja form the same length, they rarely protrude beyond the boundaries of the visual form.
- The needles are scaly, dense, tightly adjacent to the shoot, saturated green along the entire length of the stem, golden on the upper part.
- Cones folded thuja Kornik forms every season in small quantities, they are rounded, 13 cm long, consist of thin scales, at the beginning of growth they are green, by the time they ripen they are dark beige.
- Seeds are small, brown, with a transparent light wing.
- The root system of the thuja is compact, intertwined, mixed type, the deepening of the central part is up to 1,5 m.
There are no resin passages in the wood of the thuja folded Kornik, so there is no sharp coniferous smell.
The use of thuja Kornik in landscape design
The decorativeness of the folded thuja Kornik is given by the unusual arrangement of the upper part of the branches and the non-uniform color of the needles. Thuja takes root well when planted or transferred to another place. It does not give a significant increase, therefore it does not require constant crown formation. Thuja harmoniously combines with flowering plants, dwarf forms of conifers and ornamental shrubs. Thuja is used in single and mass planting for landscaping the urban area, child care facilities, gardens, summer cottages and household plots. As an example, in the photo below thuja western Kornik in ornamental gardening.

Features of reproduction
Thuja folded Kornik propagates vegetatively and by seeds. The generative method is longer, from laying the material to planting a seedling, 3 years should pass. When sowing, it is taken into account that the seeds of the folded thuja Kornik do not have a high germination rate. Of the total mass, only 60-70% of planting material will give sprouts. Cones ripen by mid-autumn, seeds are collected and left until spring. At the end of May, thuja is sown in a greenhouse or container, shoots appear by autumn. The following summer, the seedlings dive, leave for the winter, and plant in the spring.
The vegetative method is faster and more effective. You can propagate thuja Kornik by cuttings or layering. The cuttings are taken in June from the middle part of the shoots 20 cm in size. The sections are treated with a solution of manganese and planted at an angle in fertile soil. In the spring, the rooted material will sprout, it is planted in a place determined for the cultivar. The preparation of layering begins in early spring, the lower branch is added dropwise, and insulated in the fall. The next season, it will be seen how many buds have taken root, cut plots and plant thuja on the site.
Rules of landing
If they plant a thuja purchased in a nursery, pay attention to the external condition of the seedling:
- he must be at least 3 years old;
- without mechanical and infectious lesions;
- with a well developed healthy root.
Disinfection of the purchased thuja Kornik is not needed, all activities were carried out before implementation. Self-harvested seedlings are dipped in a solution of manganese for 4 hours, then the thuja is placed in Kornevin for the same amount of time.
Recommended dates
According to the description given by the originators, the thuja folded Kornik is a frost-resistant culture, shoots and roots freeze very rarely, but an adult thuja possesses these qualities. Young seedlings are not so strong, therefore, in regions with a cold climate, thuja Kornik is planted in the spring, approximately in early May. Autumn planting, even with good insulation, can result in the death of the plant. In the south, thuja folded is planted in April and early October.
Site selection and soil preparation
The plant is shade-tolerant, the decorative crown of thuja Kornik retains in partial shade and does not turn yellow in the sun. The site is selected in accordance with the design decision. The composition of the soil is only neutral, slightly alkaline is allowed.
Suitable light, aerated, with satisfactory drainage of loam or sandstone. Do not place thuja in lowlands with stagnant moisture and in wetlands. A week before planting, the soil is dug up and, if necessary, alkali-containing products are applied, they neutralize the acid in the soil. To prepare a nutrient substrate, sand, organic matter, topsoil are mixed in equal parts, superphosphate is added at the rate of 50 g / 5 kg.
Landing algorithm
They dig a hole with a diameter of 60 * 60 cm, a depth of 70 cm. The bottom is covered with a drainage cushion. Coarse gravel is suitable for the lower layer, the upper part can be filled with expanded clay, the drainage thickness is 15-20 cm.
Description of the landing of the western thuja Kornik:
- 1 hour before placing the seedling, the recess is completely filled with water.
- The nutrient substrate is divided into 2 parts, ½ close the drainage.
- Thuja is placed vertically in the center.
- Fall asleep with the rest of the fertile mixture, compact.
- The hole is filled to the top with soil left over from the excavation.
- They tamp, water, cover the trunk circle with mulch.
The root neck should be on the surface, about 2 cm above the ground.
Growing and care rules
In the photo, thuja Kornik looks spectacular. After planting, the further development of the tree will depend on proper agricultural practices: mandatory watering, timely feeding and pruning.
Watering Schedule
Young thuja up to 5 years old are watered more often than an adult tree. The schedule is determined by seasonal precipitation. In the hot period, thuja seedlings are watered 2 times a week, 5 liters of water. An adult folded thuja Kornik needs one watering in 10 days with a volume of 15 liters. To preserve moisture, thuja is mulched at any age with sawdust, peat or wood chips. In the morning or evening, sprinkling is carried out at intervals of 2 times in 6 days.
Additional fertilizing
Micronutrients introduced during planting are sufficient for the normal development of arborvitae for 4 years. On the 5th year of vegetation and subsequent top dressing is applied 2 times per season. In the spring, thuja Kornik is fertilized with special products for Cypress or Kemira Universal, in early July, thuja is watered with a concentrated solution of organic matter.
Trimming
The natural form of the crown of the western Kornik thuja is compact, dense with a bright two-tone color, does not require a shaping haircut if the event does not provide for a design intent. Health pruning thuja is necessary. Work on sanitary cleaning and molding is carried out in the spring, the damaged areas are removed and the necessary shape is given.
Preparation for winter
In the southern regions, there is enough mulch and abundant watering of the thuja in the fall. In a temperate climate, thuja Kornik is sheltered for the winter.
Preparatory work:
- Carry out water-charging irrigation.
- Increase the layer of mulch.
- The branches are fixed to the trunk with a rope so that they do not break under a layer of snow.
- Thuja is covered with burlap on top.
Arcs are installed near the seedlings and a moisture-proof material is pulled, covered with spruce branches on top.
Pests and diseases
Cultivars are less resistant to diseases and pests than wild species. According to the description for the variety, thuja western Kornik can be infected:
- A fungus that damages young shoots, they turn yellow, dry and fall off. Eliminate the disease “Fundazol”.
- Late blight, covering the entire thuja, the infection begins with waterlogging of the root ball. Thuja Kornik is treated with fungicides and transferred to another place.
- Young trees are prone to fungal infection – rust. The disease appears on young shoots as brown fragments. Thuja sheds needles, branches dry. In the fight against the problem, the drug “Hom” is effective.
The main pest on the thuja folded Kornik is aphids, they get rid of the insect “Karbofos”. Less commonly parasitic moth caterpillars – parsley. If there are a small number of them, they are collected manually, the mass accumulation is eliminated by Fumitox.
Conclusion
Thuja Kornik is a selection variety of the western folded thuja. An evergreen perennial tree with two-color needles and a vertical arrangement of the upper part of the branches is used in park design and ornamental gardening. Thuja is unpretentious in care, with a minimum annual growth, retains its shape for a long time. High frost resistance allows you to grow a cultivar in cold climates.
