Korean fir differs from other representatives of the breed in its slow growth and the color of its needles. The appearance and characteristics of plants depend on the variety. The dwarf shrub of Korean fir of the Blue Emperor variety is used to create alpine slides and decorate a personal plot with an unusual coniferous perennial.
Fir abies koreana, description of what the needles and fruits look like
Abies Koreana or Korean fir belongs to the conifer family. However, this species, unlike others, has a number of features.
Plant characteristics:
- The height of the tree reaches more than four meters.
- The crown shape is conical.
- The needles are short (its length is one or two centimeters), soft, dark green in color, with a slight shine. On the inside of the needles there are two light green stripes.
- The fruits are in the form of cylindrical purple cones. Their length ranges from five to seven centimeters, and their diameter is two and a half centimeters. The fruits ripen throughout the whole year, and at the end of autumn the cones open and seeds appear.
- The tree prefers a sunny area and is resistant to wind and cold.
Lives about one hundred and fifty years.
Let's watch an interesting video about the fir plant:
Full description of Korean fir
Korean fir is an amazingly beautiful tree. Many plant varieties have their own characteristics (color and size of needles, crown shape), but are characterized by common features:
- powerful, well-deep root system;
- spreading, cone-shaped crown;
- the bark is smooth, light gray, with thick brown-red cracks as the tree grows;
- shoots are yellowish, turning purple as they grow;
- apical buds are resinous, round;
- cylindrical cones;
- cones length up to 7 cm;
- diameter of cones up to 3 cm;
- the color of the cones is green, violet, purple as they ripen;
- lush, thick needles;
- the color of the needles ranges from silver, blue to rich, dark green;
- the needles are curved, flat, non-thorny, soft to the touch;
- needle length up to 15 mm;
- needle width up to 2.5 mm.
Cones are formed at the top of the tree crown, starting from 8-10 years of age, growing vertically upward. After ripening, they open and the seeds are released. A characteristic feature is the unique shade of the needles, which are colored on the lower part with a lighter tone or longitudinal stripes.
In sunlight, it seems that the needles on the Korean fir tree shimmer
Dimensions and height of an adult Korean fir
In the wild, Korean fir impresses with its size:
- the height of an adult tree is up to 15-20 m;
- trunk diameter up to 1 m;
- crown width up to 0.8 m.
Among modern decorative varieties there are dwarf (up to 40 cm in height) and medium-sized specimens (over 1 m in height).
Important! Fir trees are long-lived, some specimens reach 150 years of age
300-year-old Korean fir specimens are found in the wild
Growth rate
Korean fir grows very slowly in height - no more than 3-5 cm per year. The stem part, on the contrary, develops intensively. During the first 10-15 years of life, a coniferous tree grows at a slow pace. A 15-year-old Korean fir is considered mature and its growth rate increases to 30-50 cm per year.
To grow a beautiful ornamental plant on your site, you should be patient.
Where does Korean fir grow?
In its natural habitat, Korean fir grows next to birch, pine, and spruce. The plant's homeland is the southern regions of the Korean Peninsula, Jeju Island. The tree prefers rocky soil, at an altitude of up to 1850 m above sea level. A century ago, Korean fir was brought to the European part of the continent.
Due to its unpretentiousness to various climatic conditions, the evergreen tree grows throughout Europe.
Most popular varieties
Let's look at the most widespread varieties and list them in Table 1.
Variety name | Description and features |
Diamond | It is a dwarf variety. It has an oval crown shape. At the age of ten years it will reach a height of just over half a meter. The needles are dark green in color; when young, they have a more saturated color and then darken. The length of the fruit is seven centimeters, the color is purple, with hints of green. |
Compacta | The crown shape is spherical (sometimes cone-shaped). By the tenth year of life it reaches ninety centimeters in height. |
Blue standard | The crown is conical or pyramidal in shape. In ten years it grows by one and a half to two meters. The color of the needles is dark green on the outside, and white-blue on the inside. The fruits are blue, purple or violet in color. |
Molly | The tree grows very quickly, growing by five to seven centimeters in a year. The crown shape is pyramidal or cone-shaped. The shoots are branched, the trunk is even. Many fruits are formed, their color is blue-violet |
Care
Korean fir is demanding only at a young age. The first 3-5 years should be provided with sufficient care, including:
- watering;
- loosening;
- weeding;
- fertilization;
- pruning;
- protection of young seedlings from adverse environmental influences;
- prevention of diseases and pests.
It is recommended to loosen the tree trunk circle as needed. It is enough to capture 5 cm of the surface. Remove weeds in a timely manner. They take nutrients from the roots located above, create a threat of infection of the fir, and are home to many pests. Mulching with fallen pine needles will help reduce the frequency of these procedures.
Violation of the watering regime causes a decrease in immunity.
Compliance with agricultural practices protects the crop from the development of diseases. Violation of the watering regime, lack of light and air are the causes of decreased immunity. Often in this case, Korean fir is affected by rot. Dangerous pests include hermes, spider mites, and various bugs. Plants should be inspected regularly and treated with insecticides in a timely manner.
Watering
The procedure is needed only for young plants that have not had time to take root well. The exception is decorative hybrids, which are more demanding in terms of growing conditions. Korean fir prefers moist soil, without stagnant water. During the rainy season, cancel the procedure; in case of drought, water generously once every 6-8 days. The culture responds gratefully to moistening by sprinkling. It is important not to do this during the day so that the needles do not get burned under the influence of the sun.
Top dressing
The first time is carried out 3 years after planting. One spring application of fertilizer during watering is sufficient per year. You can use a complex universal additive for coniferous species. From organic matter, it is permissible to water with a weak solution of humus or bird droppings, infused for several days. It is important to water abundantly after fertilizing so as not to burn the root system.
Trimming
The crown of the Korean variety of fir forms independently. Only sanitary pruning is required to remove diseased, dried out and pest-infested branches. In autumn, it is recommended to remove the central buds on the side shoots. Some varieties do not tolerate pruning very well and may react with the appearance of dried branches. The crop grows slowly, so it will take a long time to overgrow a remote area.
Preparing for winter
Korean fir is covered with spruce branches or non-woven material for the winter.
The characteristics of many varieties of Korean fir indicate the winter hardiness of the crop. Some varieties tolerate even severe frosts well, but this only applies to adult plants. Young seedlings should be additionally covered. Mulch the tree trunk circle with pine litter, peat or sawdust. Cover the tree itself with spruce branches or non-woven material. It is not advisable to use foam, since fir requires air. The shelter also protects against burnout of needles and the formation of frost holes on the trunk.
Planting Korean fir: lighting and soil requirements
When planting fir, special attention should be paid to the choice of land and soil.
Let's discuss the requirements for the site. In this matter, the tree is quite demanding. Good lighting is a must. Lack of sunlight and even partial shade becomes disastrous for some varieties.
If tall trees grow near the chosen location, they should be removed, as their foliage will create shadow.
Almost any option is used as soil. The main thing is to refine and feed the soil. However, preference is given to acidic soils, sandy soil and soil with a large amount of organic additives.
Experts do not recommend using wetlands, as they have a high level of moisture. If it is not possible to purchase another place, then you need to install a drainage system.
Caring for Korean fir at home
Caring for Korean decorative fir requires compliance with the basic requirements of agricultural technology:
- timely and sufficient watering;
- optimal feeding;
- pruning and haircut;
- preparation for winter;
- control of diseases and pests.
At home you can grow magnificent specimens of evergreen Korean fir
Recommendations for care: watering, fertilizing
Classic care required:
- watering;
- weeding;
- feeding;
- pruning
Young seedlings need more water, as they are actively growing and strengthening their root system. As soon as planting has been carried out, after fifteen days the first watering is carried out, the procedure is repeated every fifteen days.
The same goes for container-grown trees. Mature trees are watered up to three times during the entire growing season. If there is severe drought, then water several times a month.
After watering, the soil is fluffed up and covered with mulch. For mulch, use pine needles or sawdust.
Fertilizing is carried out three years after planting. Special substances developed for the care of coniferous crops are used as fertilizers.
Landing Features
It is advisable to propagate Korean fir vegetatively. To grow on the site, it is recommended to purchase a seedling from a nursery. It is important to preserve the earthen ball and not expose the root system. For this purpose, planting is carried out using the transshipment method. It is important to choose the right location and prepare the planting hole. It is necessary to take into account varietal characteristics.
You need to remember the slow growth of the plant. Landscape designers successfully use this property to create compositions that do not require constant care and replanting. Many tall Korean firs will eventually occupy a large space, so the choice of site should be approached carefully. Transfer of an adult perennial is undesirable.
Selecting a location
The Korean variety of fir prefers well-lit areas. For the first few years, young seedlings will have to be shaded a little, then a sufficient amount of light will be required. Some varieties tolerate light shade well. Decorative subspecies with brightly colored needles require open areas for growing. The crop is wind-resistant, but young plants need to be tied to a support until the root system is well developed.
The Korean variety of fir prefers well-lit areas.
Soil requirements
The perennial prefers moist, loose soil with an acidic reaction. It is not demanding in terms of composition; it grows in natural conditions on soils depleted of nutrients. Does not tolerate heavy, clayey and swampy soils. Requires the organization of a drainage layer; from excess moisture it rots. Prepare the planting hole 2-4 weeks before planting. Place drainage at the bottom, and on top a fertile layer of sand, peat, humus and clay.
To create a lighter structure, add sawdust. Use nitrophoska as a fertilizer, but do not allow it to come into contact with the root system of the seedling. The addition of coniferous litter and soil from a pine or spruce forest will increase the survival rate of the plant in a new location.
On a note! The peculiarity of coniferous plants is that in order to obtain nutrients, mycorrhiza is necessary, which is in symbiosis with the crop.
The addition of coniferous litter and soil from a pine or spruce forest will increase the survival rate of the plant in a new location.
Planting scheme
Plant the Korean variety of fir in April or from late August to mid-September. When planting alone, the distance to other trees and shrubs should be 4-5 m. If the crop is intended to create a hedge, it is possible to reduce the distance to 2-2.5 m. The depth of the planting hole depends on the age and varietal of the Korean fir, on average it is 50-80 cm. By the time of planting, the earth should settle. Be sure to plant in a moist substrate, pre-watered abundantly. The root collar should not be buried or left on the surface.
Reproduction of fir abies koreana: seeds, layering, cuttings
Reproduction by all these methods is effective. The main thing is to do everything right. For clarity, we will place the main points in Table 2.
Reproduction method | Recommendations |
Seeds | To obtain good material, the cones are picked in advance and then dried until the seeds ripen. Then stratification is carried out. Keep the seeds in a wet substrate and growth stimulator for thirty days. Planting is first carried out in containers and left in greenhouses. Planting in open soil is carried out at the end of October or beginning of March. |
Cuttings | For propagation, only annual shoots are used. Carefully cut off the part with the apical bud, the length of which is fifteen to twenty centimeters. Dip one edge in Kornevin for 24 hours, and then place it in a container with soil mixed with humus and sand, and place it under film or glass. After a year, the containers are taken outside for hardening, and at the end of autumn they are replanted |
By layering | This is the easiest method of all. In the spring, the lower shoots are dug into the ground five centimeters deep and secured with staples. For the winter they are insulated, and after a couple of years they are disconnected from the mother bush |
Planting and caring for Korean fir
Choosing the right place for a plant, following the basic deadlines and planting algorithm is the key to a healthy and beautiful tree. Subsequent care and cultivation of Korean fir in compliance with all rules of agricultural technology allows you to obtain magnificent specimens on the site.
Deadlines
Agricultural technology for growing Korean evergreen fir requires compliance with planting deadlines. The ornamental plant can be planted in open ground in spring or summer. Such specimens require proper watering, and if certain agricultural standards are not followed, they most often die.
The best time to move seedlings into open ground is early autumn. Before the onset of winter, the planting material will gradually take root, and low autumn temperatures and increased humidity levels during this period of the year will contribute to deeper establishment.
Compliance with the correct timing of transplanting fir to the site will increase the exquisite collection of conifers in the garden
Site selection and soil preparation
Many people consider the Korean evergreen fir to be an unpretentious representative of the Pine family. A detailed study can reveal some “preferences” of an ornamental plant for a planting site:
- moist soil without stagnant water;
- good drainage system;
- loamy soil;
- sufficient amount of fertilizer.
Most varieties of decorative Korean fir prefer well-lit or slightly shaded areas
Landing algorithm
Two weeks before planting, the hole should be prepared. Its dimensions are 60x60x60 cm. 2-3 buckets of water are poured into the prepared hole until completely absorbed. The bottom is dug up, filled with crushed stone or broken brick, 5-6 cm thick. The hole is half filled with a fertile mixture of the following ingredients:
- part of the peat;
- part of the sand;
- two parts clay;
- three parts of humus;
- 10 kg of sawdust;
- 200-300 g of nitrophoska.
After two weeks, after the soil mixture has settled in the planting hole, a seedling is placed in the center of the hole, the roots are straightened and the hole is filled to the top with prepared nutrient soil.
The planting site is watered abundantly. To grow a decorative fir alley, you should maintain a distance between planting holes of 4-5 m.
The planting pattern between seedlings for loose groups is 3-3.5 m, for dense groups - 2.5 m.
Growing Korean fir
Compared to other coniferous crops, Korean ornamental fir easily adapts after moving to open ground. After final rooting, young seedlings require proper care.
Watering and fertilizing schedule
Fir is watered in case of dry summer. Moisture-loving varieties need irrigation 2-3 times during the summer season. Other species do not tolerate waterlogging; natural precipitation is sufficient for them.
Fir is fertilized 2-3 years after planting. Complex fertilizers for conifers are applied to the tree trunks of mature trees in the spring.
For one Korean decorative fir tree, 15-20 liters of water per watering is enough
Loosening and mulching
Loosening the soil around the near-trunk space of the Korean evergreen fir is indicated after each watering. This should be done to a depth of 10-15 cm. During the procedure, weeds must be completely removed.
Mulching is necessary for young seedlings. To do this, use wood chips, peat, sawdust in a layer of up to 8-10 cm.
The mulch should be located close to the root collar of the tree
Rules for cutting Korean fir
Trimming is necessary for some varieties of Korean decorative fir. Pruning is done in the spring before sap flow begins. Using garden shears, remove dry, damaged branches and, if necessary, form a crown. Spring annual pruning involves removing no more than 1/3 of the length of the branches.
In most varieties of evergreen Korean fir, the crown does not require formation
Trimming the top of a Korean fir
Experts and experienced gardeners recommend never cutting off the tops of Korean decorative fir. Such manipulations can lead to the death of the plant. This is explained by the fact that when cutting the top, the natural balance between the root system and green mass is disrupted.
Preparing Korean fir for winter
Most varieties of Korean decorative fir can withstand air temperatures down to -39 ⁰C. For winter shelter of young seedlings, you can use spruce branches, which completely cover the rhizome and crown.
Only young specimens need protection during the winter cold.
Control of common diseases and pests
Possible root rot. This occurs due to waterlogging of the soil.
Fungal diseases. For prevention, diseased branches are removed, and the cuts are treated with Bordeaux mixture and garden varnish.
Fungal infection occurs when the crown is very dense. Therefore, sometimes it is necessary to carry out sanitary pruning.
Possible damage from the following insects:
- leafworm;
- spruce moth;
- aphid;
- Hermes.
To avoid infection, trees are treated with insecticidal substances.
Recommendations
Decorative varieties of Korean fir are more demanding to care for than ordinary trees. Compliance with agricultural cultivation techniques has a beneficial effect on the external condition and characteristics of the plant.
Decorative varieties of Korean fir are more demanding to care for than ordinary trees.
Basic recommendations:
- In summer, it is advisable for Blue Emperor to provide abundant watering with sprinkling of the crown.
- For the first 2-3 years, young bushes should be protected from winter frosts and returning spring frosts. To do this, it is advisable to mulch the soil and cover the aboveground part with spruce branches or other available material.
- It tolerates a superficial pruning once a year well, but it is not advisable to shorten the shoots too much. The bush will grow slowly and take a long time to recover.
- Blue Emperor fir is recommended for use in landscape design for small flower arrangements, rock gardens, and oriental-style gardens.
- The small height and diameter of the shrub allow it to be used in garden plots with a small area.
- The variety is resistant to fungal diseases. Proper care strengthens the immune system and makes the plant resistant to adverse factors.
- Fir does not tolerate air pollution and smoke, so it is not recommended to plant it within the city.
- Loosening and mulching the soil has a beneficial effect on the crop.
It is not recommended to plant fir within the city.
Blue Emperor is a dwarf variety that is of interest to collectors, landscape designers and exotic lovers. The high decorative quality of the crown remains all year round. Fir in adulthood is quite unpretentious. It reproduces only by grafting; you can purchase a seedling at a nursery or a specialized shopping center.
Using Korean fir in landscape design
Korean fir, due to its versatility, is widely used to create landscape designs. The tree looks harmonious with other shrubs, plants, trees and compositions of flowers and herbs.
For example, you can plant larch, maple, spruce and pine nearby. Although the needles look great when planted alone.
To create landscape design, abies koreana fir is used to create alpine slides, green hedges and rocky gardens, for public gardens and parks.
The main thing is to plant all the plants correctly, choosing shades and growth. For example, Chinese fir has dwarf varieties; they should be planted together with flower arrangements, small shrubs, such as juniper or thuja.
Let's watch a video about how beautiful the fir looks on the site and learn about the characteristics of different types of this plant:

The plant is characterized by the presence of a cushion-shaped, irregularly shaped crown, up to 1.5 m in diameter. The Korean specimen is classified as slow growing crops, the annual growth of which varies from 5 to 8 cm.
A special feature of fir is the color of its needles. It has a silvery-violet or intense blue color in the upper part and white in the lower part. The needles are short, soft to the touch, and when viewed close up they resemble tiny leaves.
Important! The fir variety described is a hybrid, therefore, to preserve all varietal characteristics, the crop is propagated only through grafting.
The shrub has excellent winter hardiness and can grow in the climatic conditions of the Urals, but in this case it needs insulation for the winter. The buds of the plant are grooved, yellowish in color, and become purple as they mature.
Young branches are light green, the bark is light gray, with a smooth surface, bursts with age and becomes covered with red-brown furrows. The fruits of the shrub are small elliptical cones, 4–7 cm long, which when unripe have a blue-violet color; when ripe, they acquire a brown color with a slight purple tint.
Blue Emperor cones are located on the shoots in a vertical direction.
