- thaw during the cold season.
Characteristics
Reviews of red currant Tatiana confirm the excellent resistance of the variety to prolonged rains, significant wind load. Such climatic phenomena do not affect the process of ovary formation, which makes it possible to obtain consistently high yields of berries in any year.
Drought resistance, frost resistance
Tatiana is not intended for cultivation in arid southern regions, but is highly regarded for its excellent winter resistance in harsh conditions. It is noted that specially adapted Russian varieties of currants are able to withstand frosts down to -50 ° C.
Variety yield
Red currant Tatiana shows excellent productivity: on average, each bush yields about 5 kg of berries (16.5 t / ha). Even fully ripe fruits are not prone to shedding.
According to the timing of the return of the crop, the crop belongs to the mid-season, in the harsh conditions of the north it bears fruit later. Mass flowering begins on May 10-31, in late spring it can cover part of June. The ovaries are formed after 14 days, the berries are picked from the end of July to the beginning of September.
Application area
The culture of red currant Tatyana is suitable for industrial cultivation, and has also proven itself as an unpretentious variety for a summer residence or a plot at a country house. Its berries are good for fresh consumption, making jams, preserves, confitures, making desserts and freezing.
Pros and cons of the variety
The main advantage of the Tatiana currant variety is its high resistance to bad weather, most diseases and pests. Other benefits include:
- self-fertility;
- undemanding nutrition;
- lack of tendency to shedding and damage to berries, high safety of the crop;
- excellent taste characteristics of berries;
- high content of sugars, organic acids, iron, potassium, iodine and pectins.
The disadvantages of the culture include the formation of relatively medium-sized berries, as well as the impossibility of obtaining the maximum yield in the conditions of the northern regions. In harsh climates, Tatyana's red currant shows a small, albeit stable, yield.
Reproduction methods
The easiest way to propagate red currants is to root horizontal layers from an adult bush. To do this, well-developed shoots are placed in pre-prepared furrows 10-15 cm deep without detaching from the mother plant, pinned tightly with hooks and sprinkled with soil in the middle part.
The upper end of the branch should remain above the surface of the substrate. When it grows up to 10 cm, hilling is carried out, which is repeated after 2 weeks. In autumn, the rooted shoots are separated from the mother bush and transplanted to a permanent place.
Planting and leaving
For planting, it is optimal to use seedlings with a well-developed root system: the rhizome should be at least 15 cm long. The optimal place for Tatiana currants to grow is hills with loose soil well-lit by the sun. Sandy loam and loam are preferred as a substrate.
Before planting, the rhizome of the currant seedling Tatyana is useful to dip in a clay chatterbox. This procedure allows you to protect the developing roots from decay, drying out, and also prevents pathogenic microorganisms from entering the plant cells.
Damaged and dried shoots must be removed. The aerial part of the currant is cut to a height of 30-35 cm, which ensures the presence of at least 2-3 buds on each shoot.
A pit for a culture of the Tatiana variety must be prepared in advance, at least 14-21 days in advance. Its parameters are 60 cm in width and length, 40 cm in depth. At the bottom, it is necessary to bring 1.5-2 buckets of humus.
Immediately before planting a red currant seedling, the compost is mixed with the ground, adding mineral fertilizers to it, depending on the characteristics of the substrate. The plant is placed in a hole, preventing the roots from bending upwards, sprinkled with soil and watered abundantly. Each bush requires 20-30 liters of water.
Follow-up care
The red currant variety Tatyana is undemanding in care, however, it needs the timely implementation of basic procedures:
- To prevent the branches from breaking off with the berry harvest, a supporting frame is erected.
- Pruning is performed after the fruiting of the shrub, the shoots are shortened to a height of 25-30 cm, and at least 2-3 buds should remain on each stem (optimally 5-6).
- Watering is carried out as needed, during periods of prolonged rains they are stopped, the rest of the time it is important to keep the soil moist.
- Loosening is performed with care so as not to damage the developing root system. The event is carried out after watering or rain.
- Summer dressings include spraying the root zone with a solution of zinc sulfate and boric acid (at the rate of 2 g of each microelement per 10 liters of water) with the addition of manganese (5 g per bucket of liquid). For each plant, from 0.5 to 0.7 liters of solution is consumed.
- Autumn dressings include the introduction of 2-2.5 c / ha of phosphorus-containing fertilizers with acidic pH and 1-1.5 c / ha of potassium.
Nitrogen fertilization is performed before the start of the second growing season. It allows you to accelerate the growth of the bush and the set of new shoots. To feed the red currant of the Tatyana variety, the introduction of ammonium nitrate in an amount of 1.5-2 c / ha will be quite sufficient.
Pests and diseases
In the description of the red currant variety Tatyana, it is indicated that it is extremely resistant to most pests and fungal pathologies. To avoid infection, the plant needs regular preventive examinations. If you suspect a disease, it is enough to spray the culture with a solution of laundry soap or sprinkle the leaves with fresh ash.
Conclusion
Currant Tatiana belongs to mid-season high-yielding varieties that have proven themselves in the northern regions. It tolerates temperature extremes, prolonged rains, frosts and thaws. The shrub is suitable for cultivation on farms and in summer cottages; in the process of cultivation, it is necessary to prevent nutritional deficiencies in order to avoid loss of berry harvest.
