Red currants were first brought to Russia from Western Europe in the fourteenth century. Today, a shrub with sweet and sour berries of bright scarlet color is grown in any garden from Kaliningrad to the Far East. Among the huge variety of varieties of domestic selection, red currant Rosetta is considered one of the most popular species.
The winter hardiness of red currants is much higher than black currants
History of selection
The variety Rosetta or Rosita was obtained at the Novosibirsk Horticulture Station of the Russian Agricultural Academy, in 2004 it was included in the State Register of Breeding Achievements of the Russian Federation and recommended for cultivation in the West Siberian region.
Currant Rosetta was obtained by crossing two varieties of American selection:
- Red Cross (Red Cross) - medium ripening, with a spreading bush and large berries with a sweet and sour taste.
- Minnesota (Minnesota) - a late variety with an erect, medium-sized bush, large, sweet berries.
Description of the red currant variety Rosetta
The Rosetta currant bush is medium-sized, its shoots reach a height of 1.2 m. The branches are powerful, thick, arranged compactly, the shape of the crown is compressed. The bark on the stems is brown-red. The leaves are small, matte, wrinkled, dark green. The leaf blades have a three-lobed structure with less pronounced basal parts. Their edges are jagged, rounded, with a shallow notch at the base and a long petiole.
The pale flowers of the red currant Rosetta are collected in a raceme up to 10 cm long, with a straight, pubescent axis of medium thickness. The sepals are pinkish and arranged horizontally.
The berries at full ripeness become red, with a sweet and sour taste. Their shape is round-ovoid with a skin of medium thickness.
Characteristics
The red currant Rosita was created in Siberia. The characteristics it has acquired are fully consistent with the climate of this region and make it possible to grow berry bushes in difficult weather conditions. These features should be taken into account to avoid mistakes during planting, cultivation and care.
Drought resistance, winter hardiness
The Rosetta variety is highly drought-resistant. The plant easily tolerates hot periods, lack of rain and watering. As a result of overheating, the berries do not bake or fall off, being tolerant of heat, dehydration and drying out of the soil. Winter hardiness of red currants is high. Even in the conditions of Western Siberia, the plant does not require shelter for the winter; it is enough to just mulch the tree trunk and periodically add snow in the winter.
Do not plant red currant Rosetta next to cherries, plums and raspberries
Pollination, flowering period and ripening time
Red currant variety Rosetta is pollinated by bees. The presence of insects is necessary in order to transfer pollen to the stigmas. This does not happen with the help of wind due to its stickiness. To obtain a guaranteed harvest, several bushes should be planted nearby.
Flowering of red currant Rosetta begins in the second ten days of May, and ripening begins in late July and early August.
Productivity and fruiting, keeping quality of berries
The ripening berries of the red currant Rosetta have a pleasant sweetish taste with a pronounced sourness. Experts rate it 4 points out of five. Sugars make up 9.9%, ascorbic acid - 30.2 mg/100 g. The weight of each is from 0.8 g to 1.7 g.
When grown on an industrial scale, the average yield of the variety is 9.4 t/ha. In the conditions of a personal plot, about 3 kg are collected from one bush.
Red currant Rosetta has average transportability; the skin of the berries is thin but dense. If necessary, they can be transported over long distances. Universal use - consumed fresh, prepared jams, compotes and preserves. Frozen can be stored for up to three months.
Vegetables and strawberries can be grown next to the red currant Rosetta, since the roots of the bush are located at a depth of 50 cm
Resistance to diseases and pests
The Rosetta variety has average resistance to anthracnose and septoria. To prevent the development of diseases in a timely manner, preventive treatments of the bush should be carried out.
Anthracnose
The first symptoms of a fungal disease appear in the form of yellow spots on the leaves, which gradually dry out and fall off.To combat pathology, spraying with “Kuprozan” and “Ftolan” is carried out at a time when the buds have not yet begun to grow.
In order to prevent anthracnose, it is necessary to monitor the regularity and volume of watering.
Septoria
An indicator of the disease is white-brown spots, small at first, and later enlarging, merging and affecting the entire leaf. Small black dots are visible on them - fungal spores. As a result, the bush may gradually die, and neighboring ones may become infected with septoria. At the first signs of pathology, it is necessary to remove the diseased parts of the Rosetta red currant, and spray the healthy parts with copper-based preparations.
Copper sulfate treatment is carried out at least three times per season.
Among insects, the greatest damage to red currants is caused by glass beetle and leaf aphids. To combat them, they use chemicals, tobacco infusion, and plant garlic, marigolds and other plants with a strong odor between the bushes.
Advantages and disadvantages
With proper care, red currant Rosetta can bear fruit abundantly for twenty years in one place. When all the nuances of planting are taken into account, it gives stable yields for many years.
Red currant berries can be dried and stored for six months
Advantages of the variety:
- resistance to heat and drought;
- high frost resistance;
- large berries;
- their high taste value;
- ease of bush maintenance;
- ease of care;
- versatility of use.
Cons of the Rosetta variety:
- low resistance to anthracnose and septoria;
- poor tolerance to swampy soil.
Features of planting and care
To plant red currant Rosetta, choose a sunny place.The best neighbor for her is gooseberries. The soil must be fertile, rich in organic matter. Sandy soil is not suitable for berry bushes, but slightly acidic loams are the best choice for it. Currants do not tolerate swampiness and high groundwater.
The optimal time for planting is early spring, in which case the plant has time to take root well and prepare for the upcoming winter.
The area is cleared of weeds, the soil is loosened and holes are dug 60 cm deep and wide, located at a distance of 1.5 m from each other. Fill them with compost to 50% of the volume, add wood ash (2 cups) and previously extracted soil. Mix thoroughly. Planting of currant seedlings is carried out according to plan:
- Make a hole in the planting hole.
- Place the seedling in it at an angle of 45⁰, with the top facing north.
- Cover with soil.
- Compact the soil.
- Make a circular roller.
- Water and mulch the tree trunk circle.
The further development of the seedling depends on the correctness and thoroughness of care.
If, when planting a red currant seedling Rosetta, the roots are shortened, the replacement shoots will grow faster
Watering and fertilizing
In the first month after planting, currants are watered regularly, twice a week, using up to 10 liters of water per bush. Later, humidification is carried out in July and October, if there is no precipitation.
Fertilizing is applied three times:
- urea – in spring (20 g/m2);
- solution of bird droppings - during the flowering period (1 kg per 10 liters of water);
- wood ash - in September (100 g per bush).
Trimming
The first formative pruning of currants is carried out immediately after planting, selecting four powerful shoots on the plant and shortening them to five buds.In the second year, twice as many shoots are left, the tops of which are cut off by 20 cm. In subsequent seasons, growths located at an acute angle, dry, diseased and damaged branches are removed.
Conclusion
Red currant Rosetta was created specifically for the harsh conditions of the West Siberian region. By growing it in milder climatic conditions, a plant is obtained that has excellent characteristics that allow it to survive temperature changes, frosts, and drought while maintaining the quality of the berries and high yields.
