The name "Kopan" was obtained in honor of the breeders involved in the creation of the variety - K. N. Kopan and V. P. Kopan.

The agricultural technology of the described variety of currants is the implementation of traditional methods, which include timely watering of bushes, top dressing, pruning and preventive treatment from pests and ailments.
Seat selection and landing
Before describing the process of planting seedlings, it should be clarified which site is most suitable for planting a currant plantation. Jubilee Kopania prefers well-lit, sunny places, protected from drafts and cold winds, with a groundwater table no closer than 1.5–2 m. Currant responds well to moist soil, so it is suitable for the site from the north or north-west side.
As for the soil, it is preferable for currants to choose light, breathable, nutritious soils with a low or neutral acidity level. The best option for the plant will be loamy soil.
Planting seedlings can be done in early spring or autumn, but experts recommend giving preference to the latter option. With autumn planting, the bushes will be able to grow stronger and quickly grow.
Before carrying out work, the site for the currant plantation is carefully dug up, enriched with humus or manure, superphosphates and wood ash.
Important! The plant loves moisture, but too waterlogged soil is fatal to it. Due to prolonged exposure to moisture, the roots begin to rot, which leads to the death of the culture.
The technology for planting currant bushes is quite simple and is based on the following steps:
- 2-3 weeks before planting, dig a recess 40 × 60 cm in size;
- pour a mixture of 2 tbsp into the pit. l superphosphate, 5 kg of compost and a handful of ash;
- pour ½ bucket of settled water into the recess;
- in the pit, place the seedling at an angle of 45 °, level its root roots, fill it with soil;
- water the plant abundantly.
After planting, the shoots of the plant are shortened, leaving 2-3 buds on each.
Gardening currants does not cause much difficulty for gardeners, as it consists of the implementation of classical agricultural practices:
- Watering. Currants of the described variety prefer moderate watering, which, under normal climatic conditions, is carried out 2-3 times a month. The frequency of watering is increased with too dry and hot summers. Be sure to moisten the bushes at such moments: at the beginning of shoot growth and the formation of ovaries, in the ripening phase of the berries and after the final harvest. The shrub is watered under the root using 4-5 buckets of water per plant.
- Top dressing. For normal growth and fruiting of the culture, it is fed with nutrients throughout the growing season. The first portion of fertilizers is applied in early spring, using nitrogen-containing preparations. Two weeks later, the earth on a currant plantation is fed with organic means, for example, a solution of mullein or humus. In mid-summer, in order to improve the ripening process of the berries, humus is introduced.The last time the culture is fed in the fall, after harvesting, using phosphorus and potassium preparations.
- Loosening and mulching. Loosening the soil allows enriching it with nutrients and minerals, thereby activating the growth of the root system — that is why the procedure is performed as often as possible. To preserve moisture in the soil and create favorable conditions for the development of culture, the trunk circle is mulched with organic materials - hay, straw, sawdust.
- Weeding. The obligatory procedure for the care of currants is the destruction of weeds, which inhibit the growth of the bush and rob it of beneficial substances. Weeding is carried out regularly, as the parasite plants grow. Events must be carried out before the phase of flowering weeds.
Pest and Disease Control
Currants of the described variety have high natural immunity and are able to withstand the most common ailments and pests: powdery mildew, anthracnose, septoria, and renal mites. In rare cases, a culture may fall prey to aphid and butterfly fire attacks.
Did you know? The leader in the cultivation of black currant is Russia. Poland takes the second place, and the third rightfully belongs to Germany.
To combat diseases and for prevention several times a season, the bushes are treated with a solution of Bordeaux liquid, vitriol or store-wide fungicidal agents with a wide spectrum of action. Insecticides - for example, "Fufanon", "Aktara", Kinimiks are highly effective in combating parasites.
In addition, simple preventative measures allow to prevent the development of diseases and the appearance of pests:
- control of soil moisture and fertilizer dosage;
- regular loosening of the soil;
- weed control;
- pruning shoots, preventing thickened shrubs;
- preventive spraying of plants with insecticides and fungicides.
Trimming and shaping a bush
Currant Jubilee Kopanya is cut annually. In addition, each branch must be updated once every three years, otherwise the plant reduces its yield. Measures for trimming branches are carried out in early spring, before the start of sap flow, or in late autumn, after the leaves fall.
Important! The circumcision procedure has a beneficial effect on the formation of the crop, on the regular renewal of shoots and rationing the yield load.
In spring, circumcision consists in removing old, dry shoots damaged by snow and wind, as well as branches that thicken the bush. During the autumn pruning, annual non-fruiting shoots infected with pests, broken or too weak, which grow on the bush for more than two years and have a dark color, are cut.

Preparing for the winter
When growing currants in the northern regions with a cold climate, the shrub should be carefully prepared for winter - work begins in late October, before frosts come.
Preparing a plant for wintering includes the following steps:
- weak, infected, non-fruiting branches are pruned in the fall;
- bushes are abundantly watered, fertilized with urea;
- the soil of the trunk circle is mulched with hay, peat or straw;
- the branches are neatly bent to the soil and covered with agrofibre, burlap or other breathable material.
Experts also recommend that in winter, sprinkle a bush with a thick layer of snow so that it does not freeze even in the most severe frosts.
Harvesting and transportation of crops
The variety belongs to plants of the mid-late growing season: its fruits are ready for harvest at the end of July.Berries are picked manually or by the harvester method, as they ripen, in the morning or evening hours, when there is no dew and the scorching sun. It should be noted that the fruits have a dry separation, keep perfectly on the branches after ripening.
