Alpine currant: description and cultivation rules
It is typical for alpine currant to grow exclusively in a mountainous region, and therefore it can be concluded that this plant does not have specific care requirements. This perennial shrub is undemanding to the environment and soil composition. Alpine currant is visually very beautiful, its decorative effect allows the gardener to admire it all season. The plant is resistant even to harsh and cold climates.
Characteristics of alpine currant
Today, meeting alpine currants in a garden plot is a rather rare occurrence. The perennial shrub is renowned for its drought tolerance, winter frost tolerance, and bushy leaves. Plant height can reach up to two and a half meters. Currant, as a rule, begins to bloom by the end of the May holidays and forms densely strewn yellowish tassels, which are collected in currant inflorescences.
Alpine currant leaves are not much different from the leaves of other species. Perhaps visually they look a little smaller. The first berries ripen in July, and the harvest continues until early September.
Taste qualities do not make an unforgettable impression, nevertheless, alpine currant berries are ideal for making mixed juice or a quality addition to fruit preparations.Currant pleases with a plentiful harvest, capable of reaching seven to eight kilograms from one shrub. In terms of harvest, the productivity of one branch is approximately five years, and the entire plant is fifteen years.
External Features
Alpine currant is characterized by the presence of several differences from other types of this shrub. Let's consider them in more detail.
- Inflorescence. Consists of six whole-open petals. In the center are concentrated short stamens, painted in dull yellowish and greenish hues, which are collected in a slightly drooping lush brush.
- high shoots, the length of which can reach one and a half meters. Shoots have brownish and reddish hues.
- Small smooth leaf. Its length varies from one and a half to four centimeters. It has a rich greenish tint. As a rule, it has a three-lobed oblong or rounded shape, a border of sharp teeth, and when the autumn period sets in, they turn into a juicy or pale yellowish color.
- Quite miniature round berries grow on alpine currants. Their diameter does not exceed six to eight millimeters. The berries have a rich pink hue and look charming against the background of the leaves. However, their taste is very mediocre.
Existing varieties
To date, several varieties of alpine shrubs can be distinguished. Let's consider each of them in detail.
- A shrub with pale yellowish and small inflorescences and golden leaves is called Aurea. As a rule, it does not grow more than one and a half meters.
- For Laciniata spectacular decorative foliage with pointed teeth along the border is characteristic, as in the previous variety.The shrub is characterized by a small length - up to one meter.
- Pumilum - an extremely interesting type of currant. It has a spherical crown shape. The maximum length of the plant is one and a half meters. It has a strong root system, but begins to bear fruit only five years after planting in open ground.
I would like to pay special attention to a variety of alpine currant called "Schmidt" (in the English version - Schmidt). This variety is famous for its resistance to severe frosts and sharp temperature fluctuations. It also tolerates dry summer days. Visually it looks like a small shrub with dense branches that can germinate well and bear fruit even in the shade.
The life expectancy of one bush is thirty to forty years. The leaves have a rich greenish tint. In autumn, they acquire a yellowish color. The flower is rounded, has greenish and yellowish colors. Berries are inedible, visually resemble miniature balls. They ripen in late July and early August.

Breeding and planting
There are four methods of propagation of alpine currant: seeds, cuttings, layering and dividing the bush. The first method requires a stratification procedure. In other words, the seeds are placed in a humid place with a low temperature regime and left for a couple of weeks. They can be planted in open ground or in a container intended for growing seedlings.
When deciding to plant seeds in open ground, it is undesirable to place them at a depth of more than five millimeters.
The easiest and most convenient of all existing methods of breeding alpine currants is cuttings. This procedure, as a rule, does not last long and does not require certain skills and knowledge from the gardener. The material for planting is a young shoot, which is usually located in the forefront of the branch.
The permissible cutting diameter is five millimeters. The height should not be less than fifteen to twenty centimeters. It is advisable to stick the cutting into the ground, slightly tilting it to half the length. The preferred time for this procedure is early autumn.
For layering, a shoot with a growth or a two-year-old branch is perfect. The layering procedure is performed in order to root the shrub.
Breeding by dividing the bush is the most time-consuming method. To implement it, you will need certain experience and skills that will help you successfully cope with this task. This method is applicable only in the autumn months. First of all, you need to dig out the root system of the shrub. Then it is subjected to a close examination and divided into three or four parts. It will depend on the level of its development. Then each part is planted in the ground, watered abundantly and the mulching process is carried out.
Further care
For the proper growth and development of shrubs, special attention will be required to the choice of a well-heated and lit area. Do not forget that the landing site should not intersect with high-lying groundwater. When planting a perennial shrub as a hedge, it is recommended to keep a distance of two to three meters between plants.
As mentioned earlier, alpine currant is a non-capricious plant and does not require specific care. The same applies to the composition of the soil. However, in order for the shrub to better adapt to the new environment, it is still advisable to do some preparatory work with the soil. To do this, when digging the earth, add a small amount of materials such as humus, sand and soddy soil.
The recommended hole size for planting a perennial shrub is fifty centimeters in length, width and height. By the way, the plant is resistant to severe cold snaps and frosts. Berries do not crumble. In order for the alpine currant to grow and develop correctly, it is necessary to regularly provide it with water, add fertilizers, cut foliage, forming a shrub.
In the spring, you will need to loosen the soil to saturate it with oxygen and allow the perennial shrub to breathe. Pruning is also necessary, so you will save the plant from already dried or diseased branches. It is desirable to remove them right at the base.
Dangerous insects and diseases
Many shrubs are a real delicacy for harmful parasitic insects. Alpine currant is no exception. Like everyone else, it is subject to attacks from some representatives of dangerous pests. Butterflies, moths and aphids are a real misfortune for the gardener involved in breeding and growing.
A butterfly, as a rule, has a length of one centimeter, and its wings are capable of spanning three centimeters. This insect is dangerous in the spring. At the beginning of winter, the butterfly takes refuge in the soil under the base of the alpine currant. And when the shrub begins to bloom, the butterfly is busy laying its eggs.
The shrubs that the butterfly managed to hit are no longer treated, as this is a fruitless exercise.
Nevertheless, there is a method that can protect the plant from this parasite. To do this, cover the base of the bush with a piece of linoleum or roofing material. This will prevent the butterfly from escaping and will not have a chance to harm the plant or interfere with its flowering.
A small amount of gall aphids can also spoil the alpine currant. These insects have a body, the length of which does not exceed two millimeters. Their food is the juice of this perennial shrub. Another type of aphid is called shoot. Its danger to the plant lies in the fact that it is able to hit all the branches. Gnawing through young shoots, it inhibits their development and growth. The best and most effective means against this type of pest are drugs called Karbofos and Aktelik.
You can re-sprinkle the plant only after ten days.
By and large, alpine currants are prone to one disease that can bring significant harm - rust. When infected, it is recommended to start treatment immediately. You will need to prepare a special solution, the basis of which will be Bordeaux liquid. The proportion is one hundred grams of Bordeaux liquid per ten liters of pure water. Next, you need to water the base of the shrub at the very roots. To enhance the effect, it is permissible to spray the leaves with a solution.
