Juniper Repanda - planting and care

Juniper Repanda (juniperus communis repanda) is very popular in modern landscape design - a creeping form that covers any surface and creates a dense evergreen carpet. This variety was bred in Ireland in 1934 and is readily cultivated around the world.

Juniper Repanda - planting and care

View brief information

  • Color : Silver Green
  • Height : by 10 years reaches 30 m.
  • Crown width : 1.5 m.
  • In which regions it grows : the plant has good frost resistance and tolerates a decrease in temperature to -29 ° C, so it is willingly grown not only in the south, but also in the middle, central and northern latitudes, provided that it is well insulated for the winter.

  • Immunity : there is a high resistance to disease, if competent and timely care is provided.
  • Life expectancy : from 100 to 500 years, the region and care affect the indicators.

general characteristics

A dwarf evergreen shrub-shaped plant has several distinctive characteristics:

  • high growth - by 10 years reaches 30 m in height;
  • the crown is thick, in an adult instance, the circumference is 1.5 m;
  • slowly develops young growth - 10 cm per year;
  • branched shoots, creeping, densely covered with needles 6-8 cm long;
  • needles are non-spiky, silver-green;
  • with age, the needles form a dense emerald carpet on the surface of soil, sand or rocky ground;
  • in the second year of life, it blooms and forms the first pine cones, at 10 years old, the bush is completely covered with fruits;
  • in young conifers, cones are greenish-gray, in adults they are covered with a dense whitish bloom.

The variety description includes the ability to change color depending on the season - in winter, shoots are dark, brownish-green, in spring and summer a bright green hue.

A plant has good immunity against disease if it is provided with competent and timely care. Life expectancy is from 100 to 500 years (this is directly affected by the climatic characteristics of the region and the conditions for growth and development).

Regions

The coniferous shrub has good frost resistance and tolerates a decrease in temperature to -29 ° C. Therefore, it is willingly grown not only in the south, but also in the middle, central and northern latitudes, subject to good warming for the winter.

Landing rules

The success of growing this crop depends on the quality of the seedlings, the location and soil, as well as the subsequent care.

Seedling Selection

Healthy seedlings are suitable for planting

The best planting material is 3-4 year old plants with a closed root system. You can purchase them in containers or with an earthen lump.

Instances with open roots should not be taken, because there is a high risk of drying of the delicate root system before planting in the soil.

It is better to buy in a specialized nursery where plants with all varietal characteristics of the mother bush are sold.

When choosing, you need to carefully examine each instance for damage to diseases and parasites. In healthy seedlings, the aerial part of the greenish-bluish color contains young shoots. Shoots should be bright green, without cracks and breaks. The optimal length of the plant is 50-60 cm.

Location and Ground

This culture is not demanding on the composition and structure of the soil - it can grow on stony, sandy or clay soil, without losing its unique properties and qualities. But in order to achieve the highest decorative effect, you should choose a place with loose, fertile and moderately moist soil.

Juniper loves light shading, so it can be planted near tall trees with a spreading crown. In the summer heat, they will protect the conifer from sunburn, yellowing and death.

The site should be calm and not swamped. Due to excess moisture, the roots of plants begin to rot, and the aerial part develops faded and not so thick.

The timing

Depending on the region, the planting dates of juniper change:

  • in the south it can be planted in April-May or early September;
  • in the middle, central and northern latitudes, spring planting is recommended so that the seedlings have time to take root, grow stronger during the summer and prepare for wintering in the fall.

Landing technique

Pits are dug, observing a distance of 0.5-2 m, depending on the size of the bush.

The depth should be slightly larger than the length of the earthen coma: for an adult, ideal 70 cm, width 60 cm, for a young one - 50x50 cm.

Each third of the pit is filled with drainage - pebbles, gravel, broken brick, then half the nutrient mixture is poured from the garden, turf, sand and peat land, mixed in equal proportions. In addition, one handful of superphosphate and potassium nitrate is added.

To eliminate the risk of burning the roots, the fertile composition is sprinkled with a thin layer of garden soil, then an earthen lump with roots is lowered, all voids are covered, compacted and abundantly watered for one plant a bucket of water.

Planting is carried out in such a way that the root neck remains 4-5 cm above the surface of the earth, otherwise the young bush will decay from moisture, turn black and die.

To avoid drying out, each plant is mulched with peat, sawdust, wood chips or ordinary soil.

Care requirements

The plant needs to be looked after

Common juniper Repanda immediately after planting thrills attention and care. However, he does not need special excesses, all the actions of gardeners are standard.

  1. In the early days, shading is required, otherwise young shoots and needles can burn themselves from the sun and turn yellow. As shelter use agrofiber, burlap.
  2. Humidification around the bush and in the near-stem zone is carried out only after drying to a depth of 4-5 cm. In order to avoid burning, the delicate aerial parts are watered early in the morning or in the evening when the sun sets. The plant positively refers to the frequent sprinkling of the crown. You can irrigate every day in the evening.
  3. From top dressing, a complex mineral composition is used - superphosphate, nitrogen and potassium. Fertilize once a season - in early spring. After fertilizing, watering is carried out, which improves the quality of assimilation of nutrients and eliminates the risk of burning the root system.
  4. The horizontal juniper variety does not need pruning, because in the process of growth it independently forms a round crown shape. But the plant needs a sanitary haircut every spring - cut off all dead parts (shrunken, yellowed, broken off and damaged by diseases, parasites of the twig). To eliminate the risk of infection, the cut-off places are treated with a solution of copper sulfate.
  5. Young specimens need to provide good insulation for the winter - the near-trunk zone is spudled with earth, and the aerial part is covered with spruce spruce branches. Adult bushes tolerate short-term severe frosts well, but if they drag on for a long time, you can sprinkle needles with snowdrift or branches of spruce.

Breeding methods

The description includes successful propagation by seeds or cuttings. The first method is more time-consuming and requires a lot of patience, time. Therefore, many gardeners prefer the rooting of cuttings. This procedure is carried out in the winter (in February) or in the summer (in July).

Harvesting cuttings

Sliced ​​apical segments (length 15-20 cm) with a piece of lignified bark do not need to be treated with growth stimulants, because perfectly take root in a light soil substrate of peat and sand (1: 1).

Disembarkation

Plant them in seedlings. Expanded clay, pebbles, then the nutritional composition are laid at the bottom. The depth of embedment of shoots is 3-4 cm. Plantings are irrigated with warm water, covered with foil and placed on a sunny windowsill with the possibility of shading in the afternoon hours.

Care

All care for cuttings is to provide several conditions:

  • stable heat in the range of 20-21 ° C;
  • humidity not higher than 60%;
  • daily ventilation so that moisture does not accumulate inside the greenhouse and mold does not form;
  • irrigation with settled water at room temperature;
  • weed removal.

The rooting of juniper Repanda is a lengthy process and lasts from 2 to 3 months. As soon as the first vegetative buds appear on the cuttings, you can remove the shelter and continue to irrigate and gently loosen the soil.

Transfer to the site

This procedure is carried out no earlier than after 1.5 years of cultivation at home, because the young plant has very thin and delicate roots, which during transplantation can be injured and lead to the death of the entire bush.

The scheme and technique of transplanting is identical to the rules for planting purchased seedlings.

Disease

Juniper is immune to disease

The conifer is rarely damaged by diseases, this is possible only if the rules of planting and care are violated.

Rust

Fungal infection, which leads to bloating of shoots, needles and the central trunk.

Manifestations of the sore are red, shapeless growths on the surface of the branches. A plant can be sick for several years without losing its decorative effect, over time, its branches begin to dry out and it dies.

Treatment at an advanced stage is useless - shrubs are burned, because they are a clear threat to healthy specimens.

At the early stage of infection, damaged organs are removed with a sterile secateurs, then they are sprayed with fungicides - Skor, Ridomil Gold MC, Bayleton, Vektra or Tilt. The same means are used for preventive treatment in the spring.

Tracheomycosis

A fungal disease that develops in conditions of constant dampness, waterlogging and tightness of plantings. The infection penetrates the root system, then clogs the vessels of the shoots and trunk, blocking access to oxygen and moisture. As a result, a complete metabolism is disrupted and the bush dies. First, the upper part dries out, after that the whole crown.

The infected bushes must be disposed of, and the soil in which they grew should be shed with a solution of copper sulfate, because the infection remains in the ground for a long time. Often it is transmitted to other plants through the already affected planting material, so dubious seedlings must be treated with Fitosporin, Quadris or Maxim before planting. If the conifer is with an open root system, it is soaked for a couple of hours in the preparation Maxim.

Drying out shoots

Another dangerous fungal sore, which leads not only to the loss of decorativeness, but also the death of the entire bush. You can notice signs of infection in early spring, when the shoots of silt needles became yellow, and the bark on the trunk was covered with small, black fruit bodies of the fungus.

The cause of the disease - thickened, planting on heavy, acidified soil.

With a slight lesion, the yellowed parts are removed with sterile scissors or secateurs, the cut sites are treated with fungicides. If the area of ​​infection is large, it is better to dig and burn such a bush.

For prevention, at the end of April and in the last days of October, the bushes are irrigated with the drug Skor, Tilt or Ridomil Gold MC.

Schütte brown

This is a fungal disease, the peak of development of which occurs in the summer. Signs are the mass death and shedding of needles of the current year and the darkening of last year’s needles. Black fruiting bodies appear on them - sporulation of the pathogen.

Junipers growing on waterlogged land and in thickets are most susceptible.

On diseased bushes, all damaged needles are removed, and showered needles are also collected. The plant and the soil around it are irrigated with Ridomil Gold MC, Strobi or Skor. The same means are used for preventive purposes for irrigation in mid-April and late September.

Pests

The description of the conifer includes high resistance to pests, rarely on the crown you can find a shoot moth, spider mite or scab.

To destroy them, chemical preparations are used - insecticides. The best remedies are Fundazole, Actellic or Actara. Processing is carried out three times with an interval of a week.

Landscape application

The compact horizontal juniper will be an excellent element in the landscape design of the garden and will decorate any composition:

  • it is planted on a rocky area, along paths, in rock gardens or on extensive lawns;
  • crops that grow in breadth are planted in places with complex terrain to strengthen stairs, slopes from shedding soil;
  • many are grown as a pot culture and placed near arbors, arches, terraces;
  • Repanda goes well with any flowering and ornamental deciduous plants - roses, petunias, begonias, chrysanthemums, pelargonium and oak trees;
  • you can plant them next to other varieties of junipers, creating an ever-green composition in the design of the garden.

Gardeners reviews

Many gardeners admire Repanda. The coniferous culture is literally loved - and for good reason.

The plant is very beautiful, forms a dense, evergreen rug that covers various defects and ugly places in the garden.

It tolerates wintering well, so gardeners not only honor it in the south, but also in the middle, northern and central strip.

They note the significant advantages of this variety - it does not require trimming, which greatly facilitates care.
