Juniper Chinese - Blue Alps: planting and plant care rules


The birthplace of the juniper "Blue Alps", or Juniperus chinensis "Blue alps", is the territory of northeast China, Manchuria, Japan and North Korea. The plant is widely used for decoration of hedges, in solitary or group plantings.

Variety description

"Blue Alps" refers to the category of rather large plants, which in adulthood can reach a height of 4-4.5 meters or more. A characteristic feature is the presence of very powerful skeletal branches and a compact, attractive crown. Shoots hang down a little. Needles hard type, with spines, up to a centimeter. The main color of the needles is silver-bluish.

Juniper "Blue Alps" is a very light-loving and frost-resistant conifer and consistently receives high praise not only from professional landscape designers, but also from local amateur gardeners.

The description of the plant states the need for only simple care of plantings. However, it should be remembered that the best is growing in sunny and warm areas. Soils juniper prefers stony and sandy, and also grows well on fairly fertile and drained soils.

Planting and care

Juniper «Blue Alps» should be planted in areas well illuminated and heated by the sun. Particular attention should be paid to the indicators and the qualitative composition of the soil. It is advisable to use under planting loamy or sandy light soils with sufficient nutritional value and high-quality moisture.

If clay and heavy soils are present at the site, the nutrient mixture represented by garden soil, peat, sand and loose soil with spruce needles should be added to the prepared landing pits. Pre-laid drainage layer of broken brick. Very good results are observed when planting juniper saplings in the nutrient mixture based on two parts of turf soil, two parts of humus, two parts of peat and part of construction sand with the addition of 0.15 g of Kemira fertilizer and 0.30 g of nitrophos.

The dimensions of the landing holes directly depend on the volume of the root system of the planted juniper. Usually, the average size of the pit for planting is not less than 0.6 × 0.8 m. Immediately after planting in a permanent place in the open ground, plants should be watered abundantly and shaded from the negative effects of direct sunlight to full survival. Further care for the Blue Alps variety is to follow simple measures that are very important for the growth and development of coniferous plants: watering, weeding, shallow loosening and systematic application of top dressing.

Combination with other plants

"Blue Alps" perfectly serves as a highly decorative garden bonsai. Also, Chinese junipers are very well suited for the formation of hedges. On lawns, this representative of conifers is very often used as the main emphasis in the composition of ornamental plants and stone. An excellent solution is to create a single composition of various conifers. Such decorative planting looks great on the garden and garden plots, in the forest-park zones, as well as in recreation areas.

High decorativeness of the Chinese juniper is a good choice for decoration of young gardens and new territories. A group planting of several conifers makes it possible to fill the voids in the landscape in the shortest possible time and qualitatively and creates a composition characterized by a high degree of decorativeness.

Major diseases and their treatment

Juniper "Blue Alps" is an unpretentious plant that is not afraid of open areas and cold wind. Such plants are distinguished by low requirements for soil composition, but need good lighting. Any failures in care or violation of the rules of planting reduce the plant immunity and often become the cause of juniper diseases.

Plant description

This beautiful coniferous plant was brought to Europe and to the territory of Russia from China. The height of the adult Blue Alps shrub reaches four meters, and the strong branched crown - up to two meters. The special beauty of the needle-shaped needles is given by its silver-blue color. The central branches of a bush very powerful and dense, are located compactly.

The Chinese Blue Alps grows well in groups and singly, harmoniously fit into any rockeries and rock gardens. In addition, coniferous shrubs are planted on open lawns, rose gardens and terraces. If you plant a juniper along the fence and will properly care for it, you can get a beautiful hedge.

The decorativeness and beauty of this variety lies in its textural needles of a bluish-silver color. Juniper Blue Alps - unpretentious, does not require fertile and moist soil, is highly resistant to frost, drought and wind.

Be careful! The fruits of this plant contain hazardous substances and can have a bad effect on human health, are forbidden to use!

Landing nuances

Due to its compactness, ease of care and fastidiousness, the Blue Alps is considered one of the most popular juniper varieties, both among professionals and amateur gardeners. And so, here are a few simple rules of landing:

  1. The ideal distance between juniper bushes is from 0.5 to one and a half meters, depending on their size.
  2. In an open and well-lit area, deep pits are dug up, at the bottom of which a drainage mixture of brick chips, sand and expanded clay is poured.
  3. The land should be slightly acidic or with a neutral pH.
  4. The root collar is not buried, leaving it on the surface of the soil.
  5. The soil around the bushes fall asleep with a thick layer of sawdust.
  6. After planting juniper requires abundant watering and feeding. The ideal earthen substrate for juniper is a mixture of humus, peat, sand, as well as Kemir and nitrophos fertilizers.

Juniper develops well in sunny areas, if this is not, then a small penumbra will not hurt him. The main thing is not to plant it in the shade, so the plant will lose its decorative appeal.

Caring properly

The process of caring for shrubs does not take much power. On hot days, the plant will need abundant watering and spraying. To make it develop well, and the appearance remained healthy and attractive, the bushes need to weed and loosen. If you live in an area where there are strong frosts, then juniper must be wrapped for the winter.

Juniper diseases and pests

A great threat to juniper is Fusarium, a fungus that causes rotting of the roots and trunk. This disease is not amenable to treatment In order to prevent the appearance of fungus, every spring the plant must be treated with special means.

Under the direct rays of the sun and from a lack of moisture, juniper needles turn yellow and lose their decorative appearance. It may also indicate the development of a fungal disease. Finding the disease, the yellow branches are removed, and the plant is treated with chemicals.

A lot of problems are brought to the plant and parasites. The spider mite is especially dangerous to juniper, the appearance of which can lead to a complete loss of decoration. For treatment and prevention, you must use the drug Karate (25 g per five liters of water).

Transplantation and reproduction

Chinese juniper perfectly reproduced by layering and cuttings. However, any of these breeding methods does not guarantee the safety of the typical crown shape. Many practice seed multiplication.

If you choose grafting, planting material must be prepared before the kidneys awaken. Cuttings no longer than ten centimeters in length, must be treated with “root” and planted in soil mixture from equal parts of chernozem, river sand and needles sawdust. At the bottom must be laid a thick layer of drainage.

The cuttings are planted under a slope (60 degrees) in well-watered soil. For a successful result, you can make a greenhouse, planting cuttings in high capacity and covering them with glass.

The method of propagation by seeds is chosen for the main species, because this method does not save varietal characteristics. Before sowing, the seeds are stratified, and then placed in the same soil as the cuttings. As a rule, the first shoots appear after 1-3 years.

Let's sum up

And so, in short, the following can be derived from this article:

  • Juniper Blue Alps - coniferous shrubs, preserving decorative appearance all year round.

Juniper Blue Alps - planting, breeding and care

The bush shape, rich color, standard care and unpretentiousness to the surrounding conditions make the Blue Alps variety in demand and popular among gardeners, both professionals and amateurs. Planting and caring for the Juniper Blue Alps is quite simple.

  1. The optimal distance between the representatives of the Blue Alps juniper is from 0.5 to 1.5 meters, depending on the size of the plant.
  2. The seedling is planted in a deep hole in an open area with sufficient sunlight, only slight shading is acceptable.
  3. Drainage from sand, expanded clay or small broken bricks is filled to the bottom of the landing pit for better water flow.
  4. The soil is neutral or medium acid.
  5. The root collar is left on the surface and not buried.
  6. A thick layer of mulch of sawdust or wood chips falls asleep around the plant.
  7. After planting the ephedra needs careful watering and bait.

Cutting is the main breeding method for bush junipers. If the soil at the site for planting the cuttings is heavy and clay, then a special mixture consisting of garden soil, peat and spruce needles is poured into the pit prepared for planting. Mandatory component for the transplantation of juniper - is drainage, the plant dies in the marshy and acidic terrain. The best soil mixture for a conifer is 2 parts of humus and peat plus 1 part of sand, mineral fertilizing and nitrophoska are added to well-mixed soil.

  1. It is enough to carry out fertilizer once a year - in the spring.
  2. In the dry period, watering is necessary in the evening, and better - sprinkling to further moisten the air.
  3. Loosening is a pledge of juniper health, as it prevents the formation of rot and mold at the base of the trunk and roots.
  4. In winter, the young juniper is covered with spruce leaves in order to protect it from wind and snow.
  5. A temporary protection is constructed around the adults of single-growing trees to prevent the branches from breaking down from heavy snow and cold winds.

Blue Alps juniper grows best in sunny and windless areas, in the shade the coniferous shrub loses its excellent decorative qualities, becomes thinner and dries, loses the attractive color of pine needles and becomes loose.

Photos of juniper in landscape design

Juniper Blue Alps in landscape design looks spectacular and bright, especially in color contrast and in combination with deciduous trees. It looks great on the alpine hills, by the ponds and stylistic gardens.

Due to its small size and spectacular appearance, the culture will be a great addition to the lawn, rock garden and rock arias, harmoniously fit into the landscape composition of any stylistic direction.

Like all conifers, the Blue Alps juniper creates a human-friendly microclimate - healthy, clean and hydrated! Today this variety is popular and in demand. The plant can be found on a sanitized urban area, on landscapes of suburban areas and houses, on flowerbeds, flower beds and lawns.

Culture description

This prickly blue monster hails from China. In appearance, the Blue Alps is an evergreen shrub, like all conifers, growing about 4 meters in length. Its crown is powerful, rather sprawling, its diameter is 1.5-2 meters. The color of adult juniper bushes is silvery-gray. The needles are rather rigid, wide, at the same time thick, and the needles are well pronounced.

The growth rate of the juniper of the Chinese Blue Alps should be characterized as average, by the age of 10 years it reaches 3 meters in height and 2 meters in diameter. The right approach to caring for a plant and providing it with fertilizers promotes more intensive growth. Thus, with the right approach, the desired landscape can be created in record time.

Among the advantages of this variety are worth noting:

  • lack of requirements and special conditions
  • compactness
  • silvery bluish color
  • exquisite insect repellent.

Interesting! The plant bears fruits with useful properties and are actively used in traditional medicine.

Due to its unpretentious Blue Alps does not require special fertility of the soil and a certain level of humidity. Shrubs are equally easy to tolerate frosty winters, dry summers and strong winds. But with a sufficient amount of sunlight, the availability of high-quality drainage and regular feeding, the plant becomes more magnificent and takes on a well-groomed appearance. Yes, and grows with the Blue Alps much faster than in the absence of quality care.

Juniper cultivation

The sapling, selected with all the rules, largely determines the success of planting and further development of the plant. Before purchasing a juniper seedling, the Blue Alps are recommended to be thoroughly examined.

The best option - sold in containers young shrubs. The roots of a quality “product” fill the container completely, the root system should be without damage, and the branches should look fresh and elastic. They should be examined very carefully.

It makes sense to check with the seller - the selected sapling was always grown in a container or there was a transplant some time before the sale, for example, months or weeks. If juniper is initially grown in a cassette, then it develops easily and quickly in a new place for it, and there are no problems with further growth. But if the seedlings were grown in the soil, after which they were transplanted into a container, and even re-planted on the site, the development proceeds slowly.

Correct fit

The estimated landing sites for the Blue Alps juniper should be well warmed and illuminated by the sun. The composition of the soil should not be ignored. Despite the fact that in relation to the soil shrub does not differ in exactingness, it is preferable to choose clay and sandy loam for plantations. In case the sandy soil dominates on the site, the juniper is planted in a nutrient ground, prepared independently.

In order to prepare the soil for the juniper Blue Alps, you will need:

  • turf ground - 2 parts,
  • humus - 2 parts,
  • peat - 2 parts,
  • building sand - 1 part.

In the resulting composition should be added a little nitrophoska and Kemir mineral fertilizers.

The dimensions of the planting hole depend on the volume of the plant root system. The landing pit must be prepared several months before the planned landing. Recommended planting pit sizes: depth - 80 cm, diameter - 60 cm. After planting, juniper shrubs are watered and protected from direct sunlight for several days.

Important! After planting does not interfere and mulching of the near-barrel circle. Это позволяет сохранить в почве влагу, а также ускорить и улучшить приживаемость кустарника.Sheet humus, wet peat and garden compost are used as mulch.

How to care

Juniper shrub is not particularly whimsical, therefore, care is required a minimum. In order to ensure the plant good growth and stable decorative effect, the following actions are necessary:

  • regular watering plantings culture
  • permanent weeding
  • shallow soil loosening once a month
  • periodic fertilization,
  • the implementation of the annual pruning of the plant,
  • preparation of plants for wintering, that is, warming of young bushes with spruce branches (this guarantees juniper protection from frost and snowfall).

Correct watering

Juniper handsome watering is needed only in a period of severe drought. As a rule, during the season the plant suffices 2-3 waterings. An adult juniper Blue Alps needs to get 30 liters of water. Light spraying is also recommended, symbolic, but perfecting the decorative properties of the majestic thorn.

It is worth remembering! Spray the shrub once a week. This is done in the early morning or evening.

How to trim

The Blue Alps are trimmed with great care, dry and diseased branches are cut to the last. The desired shape - elongated or spherical - is achieved by trimming. It should be organized in early spring or late autumn.

Since this type of Chinese juniper is undemanding, it grows superbly and without additional fertilizer. However, if you feed a juniper, it will grow faster, and this will affect its decorative effect in the most favorable way.

Fertilizing organic matter is strongly recommended to alternate with the fertilizer culture through minerals. Organic fertilizers are used in the fall as part of preparing juniper for the winter. As a useful mineral for the plant, the best option is nitrophoska, which is used in early spring, even before active growth.

Once a month it is recommended to loosen the stern soil. Thanks to this procedure, the juniper root system is enriched with oxygen. In addition, all weeds that can provoke a variety of shrub diseases are eliminated.

Garden Pests and Diseases

Among the most common insect pests should be noted such parasites as:

  • aphid, not disdaining virtually any culture,
  • spider mite,
  • scythe,
  • mole

In order to prevent diseases in April or early May, it is recommended that juniper be sprayed with an insect repellent called Fitoverm. In addition to this drug, an excellent prophylactic is malathion and insecticides - Decis and Karate.

At the slightest signs of culture damage by parasites, it requires double spraying. To prepare a solution of 2 grams Fitoverma should be diluted in a liter of pure water. The interval between treatments is 2 weeks.

Juniper Blue Alps has a good immunity and, in principle, it is quite rare to get fungal and infectious diseases, except rust and alternariosis. But such problems also occur if the plant is not pruned and it is generally wrong to care for it or not to care at all. The plant is treated with Bordeaux liquid or agrarian chemicals - Fundazole or Abiga-peak.

Due to the appearance and development of fungus, as well as lack of moisture, juniper, in whole or in part, dries. Dry branches should be eliminated without delay, and cuts should be lubricated with garden pitch or natural paint.

Use in landscape design

Juniper Blue Alps will be a worthy decoration of any territory. Particularly interesting combination with deciduous trees and shrubs. This juniper harmoniously fits into purely decorative, stylized gardens with staged ponds. Blue Alps - a good version of the basis for alpine slides.

On a note! To create interesting landscape compositions juniper can be planted together with a variety of cultures.

The plant belongs to evergreen coniferous species.

In height juniper reaches 4 meters. Spreading crown grows to 2 meters in diameter.

Description of the Juniper Blue Alps:

  • needle-like needles and prickly to the touch,
  • color with a silvery bluish tint
  • the branches are thick, strong and compact;
  • juniper crown massive,
  • plant growth is rather slow
  • juniper has a pleasant and useful essential oils.

The bush is unpretentious in leaving and does not demand special attention to itself. But to please their species will be for many years.

Planting Juniper Blue Alps

First you need to choose the planting material. Carefully inspect the young juniper. The twigs should be elastic, without various stains and growths. The color of the needles should be smooth, without yellow streaks. This way you can avoid many unpleasant surprises during planting and care.

Juniper Blue Alps loves well-lit places. Therefore, before planting it must be considered. But do not choose a plot under the scorching sun. It will be great if in a certain period of the day the plant will rest in partial shade. So the needles will always have a rich color.

Landing actions:

  1. Like most plants, juniper loves light, fertile soil. If there is a problem with good soil, then peat or humus is added during planting. Very good to add a little sand and conifer needles. Such a composition will not only feed the soil, but also loosen it.
  2. The size of the pit depends on the size of the root system. Too big a hole is not worth digging, but the roots should not be too close.
  3. Drainage material is laid out on the bottom of the landing pit. It is possible to use expanded clay, crushed stone or broken brick.
  4. After the roots are sprinkled with soil, you need to water the plant abundantly and it is advisable to sprinkle with mulch near the trunk.

In hot weather, it is recommended for the first time to priten a young plant. Otherwise, juniper vulnerable during transplantation may turn yellow.

Conifer plant care

Care for juniper Blue Alps is quite simple, and there is no need to have any skills. It is enough to periodically irrigate and loosen the soil in hot weather.

If desired, the plant can be periodically subjected to a small pruning. Basically this procedure is done for aesthetic purposes. In the spring you can remove dry branches, which are usually very small. Also, some gardeners thus form the crown they need.

Juniper is experiencing winter well. Only in very cold weather can you insure the plant and cover it. But yearling junipers better cover in advance. First of all, put peat around the trunk. And then cover with spruce branches. From above the coniferous plant can be shrouded in nonwoven fabric. Just do not need as a cover to use the film. During the winter period there are often sudden changes in temperature. Frost replaces the thaw and vice versa. In such conditions, the plant will simply sopret and die.

Such a simple care does not take much time from the gardener and does not distract him from the usual important things.


Having planted at least one juniper bush of the Blue Alps, you can propagate it yourself. Even inexperienced gardeners can do this.

The first method is very difficult and time consuming. Seeds must be stratified. Otherwise, the germination rate is very low. After sowing seeds, seedlings are grown in containers for three years. And such seedlings require a lot of attention.

Therefore, most prefer to propagate juniper cuttings.

The main stages of grafting:

  • cuttings are harvested in the spring,
  • the length of the process must not exceed 7 cm,
  • process cuttings with growth stimulant,
  • prikopat them in a container with fertile and light soil.

Until autumn, containers with seedlings should be placed in a greenhouse or placed in a sunny place. Need at least a year to keep the seedlings in the container. After already planted in open ground.

Experienced gardeners recommend not cutting the cuttings, but carefully tear them off. Thus, the "heel" is formed. So it is easier to form roots.

Diseases and pests

Juniper is prone to diseases such as fusarium. This is a fungal type of disease. Fusarium provokes rotting of the root system, and then the bush itself. To cure juniper from this disease is almost impossible. The disease is spreading rapidly. In order to prevent early spring, the trunk is treated with special chemicals. You can buy them at any garden store.

Also, the juniper Blue Alps may turn yellow. This suggests exposure to aggressive sunlight and lack of moisture. Noticing yellowing needles, it must be carefully cut off. For some time, shade the shrub and provide additional watering.

These are the two main common problems. It is necessary to observe the plant, especially in the first 2-3 years after planting. After an adult juniper is no longer at risk and will not create hassle.

Use in the design of the site

Juniper is a godsend when decorating plots and territories of different directions. Often this coniferous plant is used as a hedge. It looks very beautiful and spectacular. Many use junipers for Christmas decorations during the winter holidays, decorating them with toys and garlands. Coniferous plants are ideal for decorating a recreation area. Juniper essential oils scare various insects.

Chinese juniper "Blue Alps", planting and caring for which do not require much time and effort, will create evergreen splendor on the site. It will delight all family members and create a good mood all year round.

Description of coniferous culture

The homeland of this species of juniper is China, from where it originally came to Europe, and then to Russia. This coniferous evergreen shrub can reach a height of 4 meters, and the diameter of a powerful sprawling crown is usually one and a half to two meters. Adult shrub has a silver-gray color. The needles are hard, needle-like with a pronounced texture. The branches are compact, the needles are massive, wide, strong and thick.

This variety of juniper is characterized by an average growth rate, therefore, by about ten years of age, plants reach a height of 3 meters, and their diameter usually reaches 2 meters. With proper care and fertilization, severalabout accelerate juniper growth, which allows in a relatively short time to get a finished living landscape composition on the plot.

If we talk about the features of the variety, we can note:

  • Unpretentious plants.
  • Compact size.
  • Plants differ in their silver bluish tint.
  • Pine needles have a pleasant fragrance that repels insects.

This is an unpretentious conifer, which does not impose any requirements on the indicators of soil moisture and fertility. Plants are resistant to drought, strong wind and frost. However, with a large amount of sunlight, with good drainage and regular feeding, decorative indicators improve, and the juniper grows much faster than without any care from the gardener.

Proper care

The Blue Alps is an undemanding culture that will require minimal care from a gardener. To ensure rapid growth and excellent decoration should ensure the following:

  • Water regularly planting.
  • Weed the soil.
  • Once a month to loosen the ground shallowly.
  • Systematically fertilize.
  • Perform annual pruning shrubs.

Preparing plants for the winter is in the shelter of young plants with spruce branches, which will protect them from snow and cold.

Tell you more about how to care for this decorative culture.

Annual pruning

Cut the shrub should be very carefully, removing all dry and damaged branches. By trimming, you can form the elongated or spherical crown you need. Such annual pruning is carried out in early spring or late autumn.

This type of ornamental juniper is an undemanding culture, so it can grow perfectly without any fertilizer addition. However, regularly feeding the bush can not only accelerate the pace of its growth, but also to achieve excellent ornamental plants.

We can recommend you to alternate organic fertilizing with the introduction of mineral compounds. Organics should be made in the fall when preparing shrubs for winter. But mineral fertilizer, we recommend that you use nitrophoska, you can apply in early spring, before the period of active growth.

Insect pests and diseases

If we talk about common insect pests, we note:

  • Aphid.
  • Shchitovka.
  • Spider mite.
  • Moth

To combat these insect pests, we recommend using Fitoverm, which is sprayed for preventive purposes in the spring, around April or early May. Also for the prevention and control of insects, you can use Karbofos, as well as insecticides Karate and Decis.

If you notice that your shrub is affected by such pests, then you need to carry out double treatment with Fitoverm, for which 2 grams of the drug is diluted in one liter of clean water. The interval between such spraying is two weeks.

This species of ornamental juniper has a strong immunity, therefore plants are rarely affected by various infectious and fungal diseases. We can only note rust and alternaria, which occur due to the lack of trimming bushes and improper care. To combat diseases, we recommend using Bordeaux liquid, as well as Abigak-pik and Fundazol agrochemicals.


Thus, this coniferous decorative culture is easy to care for, and at the same time it perfectly decorates the backyard territory. It will only be necessary to choose quality seedlings juniper for planting, and subsequently provide the shrub with proper care. All this ensures the decorative and rapid growth of this variety of juniper.
