"Repanda" - juniper, bred by selection at the beginning of the last century in Ireland. The evergreen coniferous plant enjoys well-deserved popularity due to its unpretentiousness, high winter hardiness, and the ability to grow in different climatic zones. A compact, outwardly attractive culture is the best suited for the decorative design of gardens and home gardens.
Common juniper "Repanda" is a creeping undersized shrub belonging to the Cypress family . Outwardly, it is a sprawling bush with a height of 30 cm to 0.5 m, the crown circumference is 2-2.5 m. The plant reaches such sizes by about 20 years with an annual growth of about 10 cm in width. A tree-like form with an upright branched trunk is quite rare, this species has a height of 4 to 12 m.
The characteristic features of "Repanda."
- Pyramidal, conical or hemispherical shape of the aerial part of a dark green color with a silver tint. In the fall, the needles become tan.
- Juniper branches are dense, dense, side shoots extend from the trunk in different directions. The densely planted needles in the form of needles seem prickly in appearance, but they are soft to the touch.
- The lower branches are actually at ground level, parallel to its surface.
- In young bushes, the bark is brown with a pronounced reddish tinge; in mature plants, it acquires a dark brown tone.
- Irish juniper is a dioecious culture that has male and female reproductive organs. The plant begins to bear fruit at the age of 10 years, at 2 years of flowering.
- Female cones are quite large, green and fragrant from resin, oval in shape. In diameter are 7-10 ml. Ripening, they become silver-blue due to a light gray coating. On the cut you can see the beet pulp.
- Male fruits have the appearance of elongated yellow spikelets, located at the base of the stem and leaf.
- The plant blooms in early summer, in August-September it bears fruit. Subsequently, seeds densely closed in flakes appear.
The life span of the plant is about 600 years or more, although this is a characteristic feature of all junipers.
Juniper ordinary can grow in sunny areas, but also in partial shade. However, it is not worthwhile to plant “Repanda” in a completely shaded place - it may lose its specific decorative color of needles.
The frost resistance of a plant is well known - it withstands frosts of up to -30 degrees, however, this does not apply to young and recently planted specimens that need to be protected with covering material during the first years.
A conifer like Repanda needs a well-drained, loose soil, because oxygen is vital to the roots . A soil with a low content of alkali and acid is suitable for the plant. Peskogrunt - a mixture of clay and sand with an acidity of 4.5-5.5 pH. Ideally, this is a medium-moist fertile soil with optimal drainage, which does not allow overmoistening and stagnation of a liquid that is dangerous for the Repanda root system.
For juniper bushes, you should choose places on the south side (both open and partial shade) . When determining the site, it is necessary to take into account the depth of groundwater - they should not be close to the surface. It is worth thinking in advance that young seedlings should have protection against strong winds - spontaneous gusts can break and confuse tender shoots. Culture with a high level of pollution is calm.
How to plant?
Juniper can be planted in spring and autumn, but experienced gardeners believe that it is better to root the plant in the spring months - in April or May. Since the culture is propagated by seeds, cuttings and cuttings, any method of cultivating it can be chosen, but it should be borne in mind that it is quite difficult to grow a varietal plant from seeds, and there is always a high percentage of risk that juniper varietal features will be lost.
If there is no desire to engage in cuttings yourself or ground the lower shoots, then there is the opportunity to buy high-quality seedlings in special gardening complexes. You need to choose a plant with healthy needles, no damage to the stems and always with an earthen lump. Typically, the roots of plants sold are neatly packaged with the soil in burlap or containers.
Best plants take root in large containers (3-5 l).
Before planting, a soil substrate is prepared to fill the planting pit - it includes turf land, peat and sand. There also add a comprehensive tool for this type of crop. In advance, you need to prepare a hole with a depth of 10 cm and a volume of 3 times the diameter of the root system. Expanded clay, sand of coarse granularity, broken brick is placed at its bottom — drainage thickness should be at least 20 cm. Substrate and fertilizer are poured on top: “Nitroammofoska” (200-300 g) or natural material , for example, the surface soil layer of pine or spruce, litter of needles - it will nourish the roots. All these blanks are carried out two weeks before disembarkation.
The subtleties of landing
- Juniper should not be planted on dry and hot days, especially young seedlings with open roots. It is advisable to do this in the absence of sun and high humidity.
- Before planting, the roots are dipped in water for 2 hours. For the rapid formation of the root system, they are treated with any suitable growth biostimulator shortly before immersion in the soil.
- A group of bushes is planted with an interval of 1.5-2 m, if their planting involves the creation of a hedge. Single plants - taking into account nearby objects: buildings, structures, fences, other trees and shrubs.
- The plant is immersed in the center of the fossa, carefully dusting the ground and spreading the root processes. It is impossible for the root neck to be too deep: in a sufficiently large plant, it should be 5-10 cm from the soil surface, in a small one, it should be flush with it.
- After completing the placement, it is necessary to water the soil abundantly around the seedling, and when the water is absorbed, mulch the surface with sawdust, wood chips and peat 6-7 cm. For 7 days, planted conifers need moderate daily irrigation.
Container sprouts are planted both in the spring and in the fall - they quickly adapt to new conditions and grow well.
Regular attention is required by young, recently planted bushes. Adult plants are more unpretentious to growing conditions. Consider what is needed for good growth and high vitality of the Irish juniper.
- Regular irrigation - seedlings need watering up to 2 times a week, for an adult bush - 2 times a month. In hot time, spraying is carried out twice a day (morning and evening), up to 3 times in 7 days. At least 12 liters of water should go to one conifer.
- Loosening, weeding and placing mulch near the trunk zone always accompany watering. Mulch with wood chips, peat and sawdust after irrigation.
- Fertilize the plants in the spring, for this they use complex mineral fertilizer containing nitrogen, potassium and phosphorus . It must be dug along with the soil near the trunk, and then watered. If the soil is not too fertile, then fertilizing should be carried out monthly during the growing season.
- Juniper of this variety does not require artistic trimming, group plantings in the form of a hedge are considered an exception, and then trimming of branches that are knocked out of the general row is allowed. But in the spring and summer, sanitary removal of dry, lifeless, diseased and spoiled shoots is carried out, sometimes it is necessary to shorten excessively long branches.
- For winter, juniper bushes bind, mulch the earth with a thick layer of wood shavings, and in regions where there is no snow, shrubs are covered with non-woven covering material. Without fail, young plants are insulated.
To prevent rust, mold and rot that occurs when there is an excess of heat and moisture, you need to regularly loosen and mulch the soil, weed weeds. Effective remedies for the prevention and treatment of juniper are Bordeaux liquid, copper sulfate, and Arcerida solution.
Planting seed and cuttings
For sowing seeds, berries are used that did not have time to completely darken, late harvesting is undesirable due to prolonged germination. Previously, the seeds are stratified by laying them in a moistened substrate of peat, sand and moss, and on top they cover with another layer of soil mixture.
In cold weather, including winter, containers with seeds should be outdoors (approximately 5 months). Thanks to this hardening, rapid germination occurs. At the end of spring, the prepared material is sown in open ground, carrying out the usual agricultural work - watering, weeding and loosening. Grown sprouts can be moved to a permanent place of residence.
It is best to propagate "Repanda" by cuttings. Young shoots up to 10 cm long with a piece of bark are cut in the spring. After cleansing from the needles, the branches in the growth stimulant solution should be held. In order for the roots to form faster, the cuttings are planted in a peat mixture and covered with a film. Plants should be in a dark room.
The main troubles at this moment are associated with constant wetting of the substrate and ventilation.
The formation of roots in juniper takes 1-1.5 months, and then it can be planted on the site.
The use of "Repanda" in landscape design
Juniper of this variety is suitable not only for planting in the form of natural fences.
- "Repanda" can be used to create alpine slides and rockeries. The shrub is combined with other conifers, flower species, can be used to decorate English lawns and the Japanese garden.
- The plant looks great in composition with other plants - lichens, heather, deciduous shrubs. For example, with spirea - "Japanese" and "Douglas", characterized by bright colors.
- Juniper ordinary may well be grown in flowerpots and tubs, decorate terraces, loggias, porches and even roofs of houses.
