Biological features
Rocky juniper is an upright growing coniferous tree or bush. Its branches are dense, tightly fitting to the trunk. The plant is up to 8 meters high and about one meter wide. The rocky juniper has a good growth rate, is unpretentious, drought-resistant, winter-hardy. It can grow in unfavorable urban conditions, it is tolerant of winds, drafts.

Planting and leaving
It is advisable to place the juniper in the sun, although a light partial shade will not hurt. Any soil is suitable, sufficiently drained. In the year of planting, it should be watered frequently, and covered with spruce branches for the winter. The trunk circle of a young tree must be mulched with pine bark, or with wood chips. In April, May, juniper can be fed with complex fertilizers. Pruning is carried out in early spring - sanitary. The plant tolerates various types of haircuts well. A rocky juniper can be transplanted with a clod of earth at any age.


Rocky juniper for landscape design

Juniper is a coniferous plant in the form of a shrub, creeping shrub or tree, the height of which can reach 15 m. Evergreen leaves, modified into needles, have a pleasant aroma with a disinfecting effect. It is noteworthy that the distribution area of ​​each plant species is limited. And only the common juniper is distributed over a rather vast territory.

Having powerful roots capable of extracting food from the soil on their own, these conifers (the photo gives an idea of ​​their appearance) feel good even on a soil poor in humus. Undemanding to watering and lighting, rocky juniper withstands low winter temperatures. Its great advantage is its very long lifespan - more than 1000 years. Gas pollution of the city, heat, gusts of wind did not prevent these plants from filling all city parks.

The use of this type in the design of the backyard area allows you to create landscapes that repeat natural landscapes. Rocky juniper looks very harmonious on an open lawn without the use of additional decorative elements - except that you can put a couple of mossy boulders nearby. You can also shade it by planting several rose bushes of the same color. An expressive composition will also turn out when placed together with heathers. But the most popular is the use of these conifers in the construction of a Japanese garden. Throughout the year, they do an excellent job of decorating the landscape.

It is good to plant rocky juniper on an alpine slide, provided that it is of impressive size. Although its growth is relatively slow, it will still need to be pruned annually to keep it from drowning out its neighbors.

If the purchased specimen is located in a container, before planting, it is necessary to place the latter in a container with water, so that the entire earthen lump will get wet. The pit in which you plant the rocky juniper, make it twice the size of its root system. It is imperative to pour a layer of drainage material, for example, crushed stone, expanded clay or broken brick. Deepening of the root collar is unacceptable.

After planting, the first time will require shading from the bright sun. Moderate watering will promote better rooting and plant development. If necessary, it is worth carrying out sanitary pruning of dry branches.

One of the interesting varieties is the "blue arrow" juniper, which reaches 8 meters. It grows rapidly, in the form of a column. The needles have a gray color, small in size. This species is not hardy and therefore requires shelter.

Designers have already fallen in love with this variety and widely use it both in small and large compositions, which consist of specimens of conifers differing in color and shape. It is beautiful both in a gravel garden and next to the heather family. It can also be used as a hedge.


Short description

If you see him once, then be sure to decide to plant the same one on your site. Most impressive is the color of its needles. The Blue arrow rock juniper can be different depending on the soil and lighting conditions. In addition, within a species there are its own varieties, which also differ from each other. There are junipers of a dark green hue, which are far from the most spectacular. Much more interesting are the varieties of a bright blue hue.

What is very remarkable, the trunk of the plant is practically not bare. For conifers, this is rare. The lower branches grow directly at the base, creating a dramatic look. Group plantings along a path or alley are especially good.


Landing technology

Due to its decorativeness, juniper is an excellent solution for a young garden. A group of several seedlings is able to immediately fill the voids and create a nice composition.

For planting light-loving varieties, an open and high-quality illuminated area with sandy loam or loamy soil is selected, which is well saturated and moistened.

A living, formed hedge of silver-blue juniper will become a bright accent of landscape design. If the soil is sufficiently clayey and heavy, a mixture of peat, garden and coniferous soil, as well as sand is added to it. Before planting, a pit is necessarily drained, broken brick or stone is poured into it.

Plants of all varieties are planted very quickly so that the root system does not have time to dry out, but carefully enough so as not to damage the young shoots and the earthy clod. Then it is watered abundantly and hides from the direct rays of the sun. The density of placement depends on the landscape composition - whether it will be a hedge, group or specimen planting. After the plant takes root in the first spring, the juniper is pruned. It must be done carefully so as not to damage the leading branches, as this will affect the beauty and growth in the future.


When to plant

It turns out that you can replant juniper at any time of the year. However, according to gardeners, the best period is autumn and early spring in order to grow ornamental juniper. A transplant in the fall has a small plus - it is high humidity, in which the earth and the crown of the plants do not give up moisture.

The best timing for transplanting juniper in the fall is the end of October. This time is the guarantee of a successful process. However, there are those who believe that the autumn period is not the best time for planting a juniper, arguing that its root system will not have time to get stronger, and the plant will not survive until spring. They insist that planting should be done in April or May, depending on the climatic conditions.

Nevertheless, when transplanting, it is worth considering which seedling was purchased. If it has an open root system, then it must be immediately transplanted into open ground, regardless of weather conditions. The polarity must also be observed. That is, in a new place, the seedling should be placed in the direction in which the juniper grew before. Transplanting in the fall or spring is always stressful for the plant. Therefore, it is recommended to plant the plants at a young age, when they can easily tolerate acclimatization.


Tools and means of protection

Conifers have interesting and unique properties, one of which is toxicity. Juniper is just that plant, the essential oil of which can negatively affect the human body. If you have to cut the "Cossack" variety, then you must use gloves so as not to harm the skin. It is required to remember that the resin is not washed off from it, which means that a protective suit or change of clothing is simply necessary. Juniper pruning in spring is done with well-sharpened pruning shears. In the process, it is required to regularly wipe it from the resin in order for it to work correctly.
