Large sizes were obtained from Selechenskaya seedlings, and the sweet taste was from Wonder Woman. Due to the beauty of the berries and the simplicity of care, the experts named the Black Boomer variety, as “boomer” is translated from English - “causing a stir”.

Experienced gardeners argue that proper agricultural technology allows currant berries to reach a weight of up to 7–7.2 g. Although it is possible to plant a crop in spring and autumn, it is best to do this in the fall (September-October). The period from August to June is also suitable. Saplings can be bought at a store or at the bazaar. Before acquiring, you should pay attention to the presence of flaws in the root system (without fractures).
Important! For high yields, it is recommended to plant different varieties of berries together. This technique stimulates mutual pollination.
Seat selection and landing
For a good harvest, this plant needs a lot of moist air and soil. For currants, loose soil with nutrients is perfect. On wetlands and acidic soils will develop poorly.On the territory, it is necessary to introduce calcareous fertilizers into the soil two years before planting.
Preparation for planting during the autumn period is as follows:
- It is necessary to scatter over the fertilizer area. Use superphosphate - 60 g and potassium salt - 20 g per square meter.
- Dig a shovel on one bayonet.
- Dig holes (35-40 cm deep and 60 wide), the distance between which should be 1.5 m. The distance between the rows - up to 3 m. This will provide comfortable care for the plant.
- In the pits, add 2 buckets of humus, fruit and berry fertilizer, compost with ash. All water.
The area where blackcurrant grows should be smooth and free of weeds, special attention should be paid to the removal of wheatgrass. The seedlings themselves should be placed at an angle of 30–40 °, to a depth of 6–7 cm. This will allow the horse system to develop and form high-quality shoots.
After planting, if there is such a need - do pruning. Then you need to water the plant well, using 1.5 buckets of water per seedling. It is advisable to mulch the soil with organic matter.
In order for the currant to yield a good harvest, in early spring it is necessary to retain moisture, to implant with nitrogen fertilizer. Per square meter, 10 g of urea is recommended. Next - mulch with any material.
During growth (in May-June), plants must be watered and fed with liquid nitrogenous substances (under the bush and foliar). If there are kidneys affected by a tick, they are removed. In case of serious damage - the bush is cut off. In the flowering period, you need to remove terry inflorescences. Do not forget to weed during ripening.
Did you know? The world leader in growing currants is Russia.
After harvesting, treatment with potash and phosphorus fertilizers is necessary. Superphosphate (100 g) is poured under the bush and half as much potassium. Further watered. In the autumn period, after harvesting, it is necessary to loosen the earth and add organic matter. If necessary, cut damaged and weak branches.
Pest and Disease Control
The variety has excellent immunity and is resistant to most diseases. But if something nevertheless happened, you can not process the plant three weeks before the maturation of the currant. In order not to harm the crop, you can use folk remedies if such a need arises. In autumn, leaves are removed from under the bushes and the soil is loosened to the allowed depth. This is done because there may be a pathogen or other pest.
Trimming and shaping a bush
This process begins immediately after the plantation is planted. All processes are cut off, while leaving 3-4 good, matured kidneys. For bushes of two or three years of age, it is worth leaving 4 developed branches, annual growths are cut out.
After that, sanitary pruning is carried out, where damaged, broken branches and weak sprouts are removed. Mature bushes should have up to 15 skeletal branches of different ages. Experts recommend leaving 2-3 young branches a year and removing old ones, from the age of 7 years.Currant pruning: a - annual seedling; b - a biennial bush; c, d - shortening of shoots. Fig. 2.

This plant is characterized by excellent frost resistance. And if you make a thorough preparation for the winter, you can count on a good harvest next season, getting rid of pests, rejuvenating the plant. Typically, this procedure includes pruning, soil preparation, fertilizer. Also bend the branches from freezing and strong wind.
Important! You can not use metal to bend the bush, because it has a high thermal conductivity, which will transmit cold to the plant.
To do this, branches are collected in 4-5 pieces and crushed with a board. A good option would be the tile, in the furrows of which the stems will be located.In areas where the air temperature can reach -35 ° C, a burying method is often used. Then the plant is covered with a layer of earth of 10 cm.
Harvesting and transportation of the crop, shelf life of berries
Berry picking lasts approximately 20 days. It depends on the number of varieties and their ripening period. Typically, an employee collects an average of 20-30 kg of crop per day. Do not drag out the work, because in this case they can crumble and lose taste. It is recommended to collect currants after dinner, when the sun goes down or in the morning when the dew drops. Can be harvested in cloudy weather. Do not do this in the heat or during rain, then the product deteriorates faster.It is necessary to use one container and not pour the currant into other containers so as not to spoil the appearance. If the berries are going to be transported, they are not completely ripened in bunches of grapes and placed in baskets or boxes with a capacity of up to 6 kg. Transportation itself should not exceed one week.
Harvested crops are stored in a cool place for the period of transportation or direct use. The Black Boomer currant variety grows well in Ukraine and Russia. Gardeners leave positive feedback and note its endurance, early growth and good yield. With proper care, it can bear fruit several times.
