Juniper Hibernika - pyramidal shrub, reaching a height of 4 meters. Its needles vary in their color from gray-green tones to bluish-green shades. The plant has pointed, but not prickly, small needles. This juniper variety is frost-resistant and at the same time perfectly tolerates partial shade, but the bright sun is very difficult for the plant to perceive. Greens may be affected by direct sunlight. The presented juniper variety perfectly tolerates any soil, the main thing is that it should have a minimum salt content.
Many landscape designers use juniper Hibernika when decorating garden plots. Planting and caring for this plant is not difficult, so even a young amateur gardener can easily cope with this task. As noted earlier, this juniper variety is unassuming with regard to the nutritional value of the soil, but the optimal mixture of land will be a combination of peat, sand and pine needles in equal proportions.
In order for the plant to stick well, it is necessary to choose young trees that are sold with a closed root system. The optimum landing time is April or May, but it can also be planted until the fall, before the first frosts occur, preferably in September.
Place for planting should be open, with maximum access of light. If you plant it in strong shading, Juniper Hibernika will lose its decorative appeal.
The size of the pit for juniper depends on the size of the rhizome plus an additional 15-20 cm, which is filled with nutritious soil. When planting plants enough to keep the distance between the bushes at least 1 meter. After planting, the soil around the trunk is mulched. A mixture of pine needles, sawdust and peat would be the best option. Watering at the root after planting is imperative.
Juniper Hibernika, the photo of which is presented below, does not require careful and scrupulous care, but in order for the plant to feel as comfortable as possible, delighting its appearance, it is worthwhile to adopt some rules.
- In the spring, the bush should be fed with a nitroammofosca, contributing 35-45 grams per square meter.
- The very same circle with the trunk is regularly cleaned of weed, loosen it, but you can mulch with a mixture of pine needles and peat.
- For the formation of the bush pruning, giving it a cone-shaped. You should not forget about regular pruning and removal of dry branches as preventive measures.
- Juniper Hibernika requires regular watering, but so that the water does not stagnate. Bring in 2 buckets of water under each bush 2-3 times a week (taking into account the weather). At the same time, an already mature, formed bush is less demanding of moisture - it is enough to water it once a decade, and in hot weather - once every 5 days.
- So that the plant was pleased with its beauty, spray the bush with a hose, washing off the dust and moistening the air, since the juniper does not tolerate dry air and dirt on the needles.
Juniper Hibernika can be propagated by seed, layering or grafting, with the latter method is the most optimal and preferred. The plant can be propagated by cuttings all year round, although it is best to do this in the spring months. At the very beginning, the stalk is rooted in the greenhouse, if it is spring, and in winter - in the greenhouse, having previously weathered the stalk in water whose temperature is 16-19 ºC. The main thing in this case is regular spraying, keeping the substrate wet and diffused lighting.
Juniper Hybernik, the description of which we give in this article, can be diluted with layering. This method is practiced by experienced gardeners, the only thing worth considering is how the creeping, but not upright growing variety during the period of intensive growth and vegetation of the plant is propagated in the majority.
Seed propagation is a long and complicated process. Seeds germinate only after a year, or even three after sowing, and therefore should not be considered as a promising method of breeding juniper.
Description of juniper common (Juniperus communis)
Due to the natural selection, many different forms of juniper appeared. The plants that make up the lower tier of light deciduous and coniferous forests, which grow in the mountainous area and on the coast, were cultivated in the 16th century. Since that time, botanists have not only made a comprehensive description of common juniper, but also brought out new varieties.
Differing in size and type of crown, plants from different parts of the world gave rise to sustainable forms. By type of branching and type of shoots, plants are most often isolated:
- with a wide squat crown and hanging shoots f. Pendula
- with a broad columnar crown and slightly drooping shoots f. Suecica
- with narrow, low column-shaped crown f. Compressa,
- with a compact, outstretched crown growing in width f. Depressa
- with narrow vertical crown and upward-pointing branches f. Hibernica
- with creeping wide crown f. S.
There are other varieties named after the discoverers or the place of detection.
Like the shape, the color of the crown of juniper is varied. In a typical plant of this species, the barbed lanceolate needles on the front side have a noticeable groove, a glossy surface and a characteristic light strip. The basic coloring of needles about one and a half centimeters long is rich green with a bluish tint. Today at the disposal of gardeners and landscape designers of juniper varieties with practical blue (Blue) or golden (Aurea) needles of young shoots.
The branches of this juniper species are covered with reddish bark, which grows brown with age and begins to peel off from the wood. At about the age of ten, plants acquire the possibility of seed multiplication. After pollination on female specimens, rounded, dense cones form, hiding three seeds each and ripening in the second year after appearance.
Forms and varieties of juniper ordinary
Wild species of juniper became fertile ground for the work of breeders.
On the basis of the juniper common, many varieties have been obtained, which are usually classified according to the size of the plant and its growth rate:
- Junipers that add 30 cm per year are considered full-growth.
- Sredneroslye plants grow 15 centimeters or a bit more per season.
- The annual growth of dwarf junipers is 8–15 cm.
- Junipers belonging to miniature varieties increase their size by no more than 8 cm.
- The plants of the micro group have the lowest growth rates for the year, growing by 1–3 cm.
Juniper varieties with drooping branches often do not fit into one group, and their growth is in different directions. So nature creates unique, weeping plants.
Juniper Ordinary Horstmann (Horstmann)
An example of such a bizarre, asymmetrical shape is the juniper found in the marshes of Germany. The plant with an average growth rate in a few years after planting reaches a height of 1.5-2.5 meters. Although at the beginning of growth, the shoots are directed upwards, lengthening, they droop, forming the original crown of the juniper ordinary Horstmann. This light-loving and unpretentious plant has green spiny needles, coarsening on adult branches.
In landscape design, the juniper of this variety is always the center of the composition, which attracts the eyes and makes one wonder the fantasy of nature.
Juniper ordinary Repanda (Repanda)
One of the most common forms of juniper is a shrub with a flat, round or creeping crown. The height of the juniper ordinary Repanda does not exceed 30 cm, but in breadth the branches expand to a diameter of one and a half meters.
The variety from Ireland without signs of defeat can withstand forty-degree frosts, but in a continental climate, bushes can suffer from excessive dry air. According to the description, the juniper ordinary of this variety has a needleless needle, curved inside, a little less than a centimeter long. The krone is green with a silvery shade formed by light stripes on the needles.
Juniper ordinary Green Carpet (Green Carpet)
The juniper ordinary Green Carpet is very close to the variety Repanda. Its name is very eloquent. Indeed, a horizontally growing shrub forms a green carpet with a height of only 10–15 cm. Due to its short stature, the plant is not afraid of cold winters, does not suffer from wind and can withstand temperatures down to −40 ° C.
Juniper ordinary Hibernika (Hibernica)
Another Irish juniper variety has the shape of a narrow pyramid or column. The plant has been cultivated for about 200 years. The shrub is valued for its bright, non-dull winter needles and dense crown formed by upward-growing shoots. An adult juniper reaches a height of 4 to 8 meters, throughout the year decorating the garden with green and blue non-sharp needles.
In Russian conditions, juniper Hibernika ordinary is not going through the winter everywhere. The frost limit of the plant is –17 ° C.
Juniper ordinary Arnold (Arnold)
The height of an adult shrub of this variety does not exceed one or two meters. Arnold juniper plants are distinguished by a narrow shape, resembling a column or a pyramid, an increase of only 10 m per year, as well as prickly short needles of a greenish-gray or silver-blue shade.
Juniper Meyer (Mayer)
In the middle of the last century, the German breeder Erich Meier received a juniper variety with a broad pyramid-like crown. The photophilous and frost-resistant shrub grows to a height of three meters and is named after the creator.
Landscaping and lovers of conifers have a juniper Meyer’s pride due to the decorative crown and silver-green needles covering it. Prickly needles with a glossy surface resemble spruce needles, making the juniper look like a popular conifer.
Juniper ordinary Suecica (Suecica)
Common European sutica juniper does not retain a single pyramidal shape. The shrub forms several trunks at once, as they grow to a height of 10 meters. Fancy crown consists of a set of upright growing, drooping on the ends of the branches. The variety with a small annual increase, high winter hardiness and excellent decorative qualities easily finds a place in the design of summer cottages, parks and city squares.
Planting and caring for juniper ordinary
Common juniper is a light-loving evergreen plant, due to its unpretentiousness it takes root in the conditions of the penumbra. In the summer cottage, a sunny, sheltered from the wind place with a light, moderately nourishing soil is selected for the plant.
The shrub is transferred to the ground in spring, in April or May, or in autumn, before the arrival of frost. To simplify the care of juniper ordinary after planting, the pit is prepared in advance.
- The bottom of the pit, which is somewhat larger than the root system of the shrub, is lined with a drainage layer of brick dust, sand or expanded clay.
- Then prepare the mixture on the basis of sod land, sand and peat with the addition of clay.
- As an additional feed, nitrogen-phosphorus fertilizers are added to the soil.
- If the soil is acidic, dolomite flour is added to it.
- Landing is carried out in 10 - 15 days, when the ground settles.
- The seedling in the pit is placed so that the root neck is several centimeters above the ground or flush with it.
- After filling the pit, the soil is compacted and watered, and then the circle is abundantly mulched.
The description of a juniper ordinary includes a mention of unpretentiousness of a plant. This is so, therefore, care for the shrubs is not difficult. In the hot landing time watered. Irrigation will help to maintain the tone and decorativeness of the needles.
Soil treatment under the juniper consists of shallow loosening, weeding and spring dressing with the help of complex mixtures for ornamental hops. If the plant is planted on rocky or sandy soil, fertilizer is applied more often.
If the plants planted on the plot are to become a hedge, regular, but neat cutting of the juniper is carried out. It is carried out in the spring or at the beginning of the summer so that the increase in winter appears to be stronger.
Junipers do not grow so fast, so improper pruning will remind yourself for a long time. Drooping and creeping plants do not shear.
In the fall, they are doing sanitary pruning of juniper, they clean the soil from plant debris, spray the bushes and the soil under it with Bordeaux mud or other fungicide. Adult plants adapted for wintering in a particular region are not covered for winter. Crowns of young junipers are fixed with a string, covered with spruce leaves and covered with snow.
And a little about the secrets.
The story of one of our readers Irina Volodina:
My eyes were especially frustrating, surrounded by large wrinkles plus dark circles and swelling. How to remove wrinkles and bags under the eyes completely? How to cope with swelling and redness? But nothing is so old or young man as his eyes.
But how to rejuvenate them? Plastic surgery? I found out - no less than 5 thousand dollars. Hardware procedures - photorejuvenation, gas-liquid pilling, radio lifting, laser facelift? Slightly more accessible - the course costs 1.5-2 thousand dollars. And when to find all this time? Yes, and still expensive. Especially now. Therefore, for myself, I chose another way.
Junipers in the garden
Junipers can be attributed to unusual group of garden plantswhich are very different in appearance from each other. Among them are species that look like tall trees, large shrubs and quite small withcalving specimens. The krone can be sprawling, drooping and narrow, columnar.
These conifers can be found in many areas of the world: in North Africa, Europe, North America and in Asia.
The most suitable climate for them is moderate. Junipers are unpretentious and can grow on scarce soils. These plants are long-livers.
The variety of forms appeared due to natural selection, when some species disappeared, while others were modified and continued to exist, adapting to external conditions. Their domestication took place in the 16th century. Over the centuries since then, new varieties have been developed that allow us to enjoy elegant plants in our garden.
Homeland varieties Hibernika is Ireland. In 1838, the varietal name of juniper Hibernica was registered. Juniper received wide distribution in the first half of the 19th century.
Juniper ordinary Hibernika
The narrow, pyramidal shape of the crown can be 1-1.5 meters in diameter. Juniper high. A ten year old plant can reach 5 meters in height. The average annual increase is 15 cm in height, 5 cm in width. Differs a variety of high life expectancy. There are specimens about 300 years old.
The juniper is colonic, when describing the appearance of which the color of the needles is particularly prominent, bluish-green, needle-shaped, changes its shade to dark green by the winter time. During the growing season it is not barbed. Located on the branches, tightly pressed to the trunk. The branches grow vertically upwards, thickening as the plant grows.
On a note! According to the description of the female juniper Hibernik fruits are round cones. In the immature state of green, as aging grows a bluish-black color. Their size varies in the range of 0.6-0.9 cm.
Juniper Hibernika ordinary can be propagated by using seeds, and grafting or layering. Considered the best preparation and planting cuttings. The choice of this method allows you to get exactly the same in appearance shrub.
You can prepare the cuttings for planting throughout the year, but it is better to adhere to the following scheme.
In the spring period rooting cuttings in a greenhouse or greenhouse. When rooting in winter, it is necessary to first hold the cutting in water at a temperature of 16-19 ° C.
Important! In the process of rooting cuttings, it is necessary to regularly sprinkle seedlings, create diffused illumination and maintain the humidity of the soil substrate.
The dimensions of the planting pit should accommodate the root system of the seedling and exceed the size of the earthen coma by 2-3 times. The optimum depth of the pit is 70 cm, at the bottom of which it is necessary to create a drainage layer.
Between adjacent plants, the distance should be at least 50 cm. It should be planted in a sunny place. Selecting a shaded area will result in loose crown formation and loss of decorative appearance. The root neck should be on the same level with the soil layer.
It is necessary to choose the sites freed from the shadow. Short-term, as opposed to permanent, shading will not affect the decorativeness of the variety.
Note! With the close occurrence of groundwater, it is necessary to create a drained layer, 10–20 cm thick, of crushed brick or expanded clay.
As a soil mixture, it is necessary to mix peat, sod land and sand in a ratio of 2: 1: 1. At the same time, the acid-base characteristic of the soil should be in the range of 4.5-6.5 pH units. The alkalized or salted soils are unfavorable for the cultivation of juniper Hibernika.
In addition to grafting, you can propagate the juniper plant with the help of layering. When choosing such a method, you should choose creeping shoots, and not straight-growing. The optimal time is intensive growth and vegetation of the plant.
Selected shoots should be prikopat, securing it in a bent position. After a year, the rooted part can be transplanted to another location. The transplanted shrub will adapt to the new conditions in the first two years.
Interesting! Juniper Hibernica is not picky about the conditions of care. The only tough condition for good growth is to maintain abundant regular watering. On one tree after planting must be made 20 liters of water. The decorative look will be better formed on soils with medium moisture.
In dry periods, it is recommended to increase watering and to additionally spraying. Sprinkling at intervals of 1 every 7 days in the evening will give the needles extra shine.
Shallow loosening has a beneficial effect on growth. Loosening after irrigation will enrich the soil with oxygen, preventing the development of putrefactive processes. To simplify weeding, you can mulch the soil around the tree. Creating a mulch of peat layer of 3-5 cm in the dry season will further preserve the soil moisture.
Care pruning is to remove dry and damaged branches. It is better to carry out pruning in the spring, after the final snow melt. Sharp pruners need to carefully cut off the branches injured under the weight of snow. As such, the crown formation in the Hibernik variety is absent.
Make a mixture of fertilizers once a season. The first feeding is carried out in late April - early May. Nitroammofosk (35-45 grams per 1 sq. Meter) and complex preparations, for example, Kemira-Universal, are suitable for this.
On a note! To prepare for wintering, young plants need to be covered with spruce leaves, since seedlings may not tolerate sub-zero temperatures. Covering adult plants is not necessary. In order to avoid breaking the branches under the weight of snow in autumn, the branches should be pressed to the trunk with ribbons or ropes.
Diseases and pests
Junipers have a strong immune system. However, if the standards of care and maintenance are not followed, trees can become infected with pests and various diseases.
The most dangerous parasite of the juniper variety Hibernik is sawfly. The needles enter its diet. After the snow melts, sawflies feed on old needles, moving on to young shoots. In this case, damage occurs not only to the needles, but also to the branches of the tree. To detect pest infestation can be by the presence of damaged needles and bald spots on the branches.
You can get rid of the sawfly in several ways: hand picking, attracting birds, installing adhesive plates. In addition, it is necessary to dig up the soil around the tree in order to get rid of possible pupae. Fallen needles need to burn. In the period of occurrence of the caterpillars, the plants must be treated with Kinmiks, Decis or Karbofos.
Important! When a plant is infected with a needle mite, there is an increase in the ends of the needles. It is possible to get rid of the parasite by treatment with commercial preparations (Karate, Akarina) at the beginning of May. A similar effect has a popular recipe for a warm soap solution with the addition of horseradish leaves or garlic.
The fungal disease Fusarium can lead to a decrease in the ornamental plant. Yellowing of the needles, drying of the plant is due to the defeat of the root system of the plant. The roots change color to red and die off. At the first signs of this disease, it is necessary to immediately dig up the infected specimen and treat the roots with a fungicide preparation (Baktofit, Vitaros). The remaining soil should be treated with solutions of Gamair or Alirin-B.
Diseases and pests
Application in landscape design
The columnar shape of the juniper Hybernika is often used as a focal plant when placed on flower beds. Often a variety is used as a tapeworm on lawn expanses. The color of the needles plays effectively in the preparation of group plantings with deciduous trees.
Interesting. Hibernika resembles the shape of the crown cypress and can be used to cultivate the tracks and create a hedge.
The size of the crown should be considered when choosing neighboring plants. In addition, juniper prefers acidified soils, so planting plants in close proximity costs plants with the same preferences for soil reaction.
Summing up, we can say that the juniper variety Hibernika will surely attract attention with its harmonious appearance. The lack of high requirements for soil and conditions of detention makes the plant attractive for decorative use. High frost resistance allows growing the plant in climatic zones with low temperatures in winter. Despite the high resistance to various diseases, failure to comply with hygienic standards can lead to a decrease in the ornamental appearance and the death of the plant. Following the simple requirements for care will allow for a long time to admire a healthy plant in the garden.
Types of juniper
Juniper forms are initially divided by branching and mind shoots. The following subspecies are distinguished:
- with a narrow, elongated crown, and branches growing up,
- with a compact and narrow columnar crown,
- with a wide squat crown and hanging shoots,
- with an extensive columnar crown and slightly drooping escapes,
- with a squat crown growing in width
- with low creeping crown.
Junipers are usually named after a natural habitat or in honor of the discoverer of the species. The needles can be varied colored. In addition to the green needles with a gray tint, there are golden and blue varieties.
Juniper is also divided by growth rate. Full-grown grows by 30 cm per year, medium-growing - by 15 cm, dwarf varieties - by 8-15 cm per year, miniature - up to 8 cm annually, micro - only by 1-3 cm.
The following varieties of juniper are most popular in culture: Horstmman, Repanda, Green Carpet, Arnold, Meyer, Suitzik, Hibernik.
Description of juniper Hibernik
Homeland of this variety - Ireland. This elegant shrub has a narrow columnar crown. During growth, the branches of the juniper are directed upwards and remain straight in adulthood. Growth is achieved slowly, in the year the plant adds only 15 cm in height and up to 5 cm in diameter.
An adult plant grows to 3.5 meters. Having reached the maximum height, the juniper begins to condense and expand the crown. The needles consist of soft needles of green color with a gray shade. In order for the crown to remain dense, juniper Hibernika ordinary planted in well-lit places. But from the spring sunlight the plant can get burned.
In group plantings Hibernika looks good with heather, roses, decorative cereals, dwarf pine. Organically look next to a juniper composition of stones. The plant is often grown in containers to be used for landscaping terraces, loggias, recreation areas on the roof. This variety is considered unpretentious and suitable for cultivation, even in urban pollution.
Best juniper Hibernika suitable for planting open sunny places, but it can endure without loss of attractiveness and slight shading.
- When planting the root collar is not buried, it should be at ground level.
- If groundwater is close, it is necessary to provide drainage. To do this, lay a layer of rubble or broken brick with a thickness of 10 to 20 centimeters.
- A mixture of 2 parts of peat, 1 part of sand and 1 part of sod land is laid in a landing pit 70 cm deep. The acidity index of the soil should be in the range of 4.5-6.5 pH.
- After planting, the soil under the plant is mulched with a layer of 3 to 5 centimeters of soil or peat.
- The soil under the young plants between watering need to loosen, as well as remove weeds from it.
- The young juniper gets acclimatized for a long time, 2-3 years. Adult transplant plants do not tolerate well.
For active growth of juniper deoev recommended feed up. Fertilizers are applied in May-April, digging nitrophoska with the soil near the plant at the rate of 40 grams per square meter.
According to the description, this variety does not tolerate a deficiency of moisture in the soil and dry air around. In hot weather, it is advisable to spray Hibernica in the evenings once a week.
While the plant is young, it needs more frequent watering. An adult juniper is watered 2-3 times per season, if it does not rain.
Juniperus Hibernika does not need pruning because it is too slow to grow. Cut only dried twigs, maintaining the appearance of conifers.
An adult plant is quite resistant to frost and does not need any shelter, but because of the columnar form, the crown is tied up before snow falls, otherwise branches may break off under the weight of the snow mass. Young juniper bushes in the first winter must cover.
Hibernica can be propagated by cuttings, layering and seed method. Most often resort to cuttings. Cuttings can be done year-round, but this is best done in early spring. First, they are soaked in root solution in a solution, and then planted in loose soil in a greenhouse or greenhouse. During the rooting period, it is necessary to maintain the air temperature of 16-18 ° C. The light must be diffused, the soil is regularly moistened, and the seedlings are sprayed.
The method of propagation by layering is more suitable for creeping varieties that produce numerous shoots, but it can also be used for Hiberniki. Sowing of seeds will give its fruits not earlier than in a year, shoots may appear even later, therefore this method is practically not used.
