Features of growing leaf hybrid cabbage Redbor f1
Redbor cabbage F1 is an exotic representative of hybrid varieties of kale. It is distinguished not only by its high taste, but also by its rare beauty - it is often used in landscape design. Thanks to its frost resistance, the curly dark purple leaves look great even under the cover of snow. Having studied the features of growing Redbor F1 kale, it is not difficult to get your own harvest.
Description of the cabbage hybrid Redbor F1
Hybrid Redbor F1 has not yet become widespread among domestic gardeners, but many have already become interested in this crop and are successfully developing it on their land plots.
Origin and development
In 2000, the late-ripening hybrid Redbor F1 was included in the State Register for garden plots, household plots and small farms. The culture was bred by Dutch breeders from wild species, from which they inherited unpretentiousness and resistance to adverse natural and climatic conditions.
The “ancestor” of Redbor had leaves that were smooth, monochromatic and with an even edge, but during the breeding process their edges became corrugated, reminiscent of a fringe. The leaves are purple and have an exotic appearance.
Breeding history
The practical application of the achieved results (frost resistance, high yield, early ripening) by crossing two varieties began at the beginning of the 20th century. Redbor F1 is one of the most successful modern hybrids.
Now the crop is widely used in countries with developed agriculture.
What kind of species is this and how does it differ from the usual one?
Redbor differs from other varieties and hybrids of cabbage in that it does not form a head of cabbage.. The plant has the appearance of a loose rosette of leaves with lacy edges, rather thin, but at the same time juicy, purple in color. Grows as a bush 1.5 m high.
The plant is biennial and produces a harvest in the second year after planting.. It has another unusual feature - the active growth of lateral leaves, which makes it possible to repeatedly harvest.
Chemical composition, trace elements and vitamins, beneficial properties
Curly cabbage is significantly ahead of its “relatives” in terms of the content of nutrients. In terms of protein content, it is an excellent alternative to meat, and in terms of Omega-3 fatty acid content, it is an excellent alternative to fish products. In addition to 25 vital amino acids, 100 g of leaves are rich in vitamins and minerals.
Vitamins:
- A – 681 mcg,
- B – 0.7 mg,
- PP – 0.5 mg,
- C – 41 mg,
- B-carotene – 8.173 mg.
Minerals:
- potassium – 228 mg,
- magnesium – 18 mg,
- phosphorus – 28 mg,
- zinc – 0.24 mg,
- selenium – 0.9 mcg,
- calcium – 72 mg (contained in the same amount as in dairy products).
Redbor contains antioxidants – glucosinolate and sulforaphane, which prevent the development of cancer cells.
Cabbage improves the functioning of the digestive system and prevents constipation, strengthens the immune system, prevents bone loss, improves vision, regulates blood glucose levels, etc.
Features of application
Luxurious curly leaves of Redbora have attracted the attention of designers from different countries, therefore the hybrid is successfully used in landscape gardening, especially in China and Japan.
Cabbage is stewed, boiled, consumed raw, used in medicine and cosmetology.
Ripening time and yield
Redbor bushes grow until the end of summer, and the harvest ripens after 3 months after emergence (the height of the leaves of the rosette at this time is 20-25 cm).
The culture produces high yields – approximately 3-7 kg/m² of succulent leaves, regardless of weather conditions.
Disease resistance
Cabbage is distinguished by its strong immunity to typical diseases and insects - clubroot and cabbage fly are not terrible for the plant, but it not immune from the invasion of other pests:
- aphids;
- cruciferous fleas;
- cabbage scoop;
- leaf beetles
The resistance of Redbor F1 cabbage is increased using “Immunocytophyte”, sodium humate.

Cold resistance
An important feature of the hybrid is its amazing resistance to low temperatures. (down to -18°C). After the first frost, the leaves become even more juicy and soft, without losing not only their decorative properties, but also their beneficial properties. Under the influence of low temperatures they acquire a more saturated color and a pleasant sweetish taste.
Plant characteristics
Redbor belongs to the Cruciferae family and is considered one of the most popular hybrids.. This beautiful emerald-purple vegetable has lush leaves and is shaped like a palm tree. The head of cabbage is not formed. Sometimes the height of the plant reaches 150 cm and belongs to the late-ripening group.
Attention! There is no bitterness characteristic of cruciferous crops. Vegetable dishes are tender and pleasant to the taste.
For which regions is it best suited and what are the climate requirements?
Since the hybrid is unpretentious and resistant to harsh weather and climatic conditions, it is grown throughout the country - from the Far East to Arkhangelsk, that is, almost everywhere, with the exception of areas with an Arctic climate. It safely tolerates high temperatures up to +30°C and low temperatures down to -18°C, so there is no point in creating special conditions and growing it in greenhouses or greenhouses.
The main advantages and disadvantages of the Redbor hybrid
Cabbage effectively decorates beds, flower beds, and has other benefits.:
adapts to various cultivation conditions;- pleasant and unusual in taste;
- tolerates light shading;
- resistant to shooting;
- suitable for cultivation in different soil conditions throughout the agricultural territory of the Russian Federation;
- not afraid of low temperatures.
The disadvantages of a hybrid include:
- short shelf life;
- risk of damage from insect pests.
What is the difference from other varieties and hybrids
This variety of cruciferous vegetables is a versatile vegetable that does not have a head.. It is also distinguished by the presence of juicy petioles, used in cooking due to its pleasant taste. In other hybrids they are hard and not suitable for consumption.
Redbor is also significantly ahead of its cabbage “relatives” in terms of the content of nutrients.
Features of planting and growing
Agricultural technology is almost the same from cultivating conventional varieties.
Preparing for landing
Because the plant is spreading, under suitable conditions reaching 2 m in diameter, an appropriate landing area is allocated for it.
Seed preparation
For better germination, they are soaked for 20 minutes. in warm water or treated with “Epin”, “Agate”.Then they are placed in a wet cloth for 2-3 days and left in a warm place for germination.
Preparing seedlings
Hatched seeds are planted in peat pots small diameter or plastic cups filled with soil mixture. The grains germinate within 5-7 days, and seedlings are suitable for planting in the ground 35-45 days after emergence.
How to plant without seedlings
This method involves sowing seeds directly into the ground.. When choosing a site for sowing, take into account that Redbor, like other cabbage, prefers sunny places. Even a small shadow affects the growing season of the crop: the leaves become smaller, coarser, the bright color fades, which will subsequently affect the yield of the vegetable.
Soil requirements
Although kale is undemanding to soil properties, gardeners note that rosettes develop much better in soil with these characteristics:
- medium acidity;
- availability of fertilizing with humus and manure;
- good drainage layer (sand, crushed stone).
Redbor cabbage grows bitter on acidic and poor soils, and its leaves are small. Therefore, when digging, slaked lime or dolomite flour must be added.
Predecessors
It is undesirable to plant a plant where its “relatives” were cultivated last season. from the cruciferous family, since they have common pests and diseases. Do not plant after beets, carrots, radishes, rutabaga, radishes, daikon.
The best predecessors are any nightshade, legumes, pumpkin, herbs and grains.
Dates, scheme and rules of planting
Hybrid seeds germinate already at +5°C. Therefore, they begin to plant them in early or mid-April.
Planting scheme:
- Holes are made at a distance of 45 cm for the seeds, humus and wood ash are placed in them.
- Plant the seeds in rows with a gap of 50 cm between them.
For seedlings, the planting scheme is similar.
Planting density and depth
The grains are buried 1.5 cm, no more. Place 3-4 pieces in each hole. Then water and sprinkle with soil.
Seedlings are planted to such a depth that is necessary for comfortable placement of the root system and is covered with soil until the first leaves. Planting density – 4-5 bushes per 1 m², spacing – 60 cm.
Features of cultivation
Crops are covered with film to protect them from night cold snaps. and return frosts. When sprouts appear (after 5-7 days), the covering is removed. The seedlings are thinned out - only one of the strongest sprouts is left in each hole.
Seedlings are planted according to the scheme in the morning or evening, accompanied by abundant watering. They provide seedlings with shelter from possible temperature changes and sunlight. As soon as the seedlings get stronger, it is removed.

Nuances of care
Favorable temperature for the growth and development of Redbor cabbage – from +10 to +20°C. The hybrid is cared for in much the same way as other varieties of cabbage.
Watering mode
Kale is a moisture-loving plant, so it requires regular watering at the root.. To do this, circular grooves are made around the plants so that the water does not spread, but penetrates directly to the root system. During the dry period, the frequency of watering is increased and care is taken to ensure that the soil is always moist.
Important! Spraying of bushes is carried out only after sunset.
Loosening and hilling
After each watering, the row spacing is loosened and the cabbage stems are lightly hilled up., get rid of weeds as necessary. By mulching the soil with a layer of straw or rotted sawdust, the number of loosening and watering is reduced.
Top dressing
In order for cabbage rosettes to develop well, they are fertilized twice: 12-14 days after emergence, and 2 weeks later the procedure is repeated. Approximate composition of solution per bucket of water:
- for the first application - 10 g of urea, 20 g of superphosphate and potassium chloride;
- the second feeding is increased by 1.5 times, 1 g of molybdenum and 3 g of borax are added to it.
Measures to increase yield
Increasing the productivity of kale largely depends on a correctly selected set of agrotechnical measures carried out during the growing season of the crop. To get a rich harvest of the Redbor F1 hybrid, it is enough to prepare the area for planting well and water the plantings in a timely manner. In general, the hybrid is quite picky and grows a large green mass of leaves until frost.
Disease and pest control
Although hybrids are characterized by resistance to many diseases (grey rot, clubroot) and pests (aphids, cabbage fly), In order to protect themselves, they still take preventive measures:
- Regularly loosen the soil to increase aeration to prevent gray rot from spreading.
- Dust the plantings with ash or tobacco dust to repel the cruciferous flea beetle.
- Spray with infusion of onion peels and wormwood to destroy aphids.
Harvest and storage
Cleaning is carried out in one of two ways:
- they tear off the larger side leaves and leave the smaller leaves;
- The entire plant is cut off and stored in a cool place until processing.
When to collect
Growing leaves are collected throughout the summer. The younger they are, the more tender and tasty they are.They are cut early in the morning, when the leaves are maximally saturated with moisture.
As soon as during the growth process the leaves begin to coarse and lose their taste., carry out the final harvest. The entire growing season lasts up to 180 days.
Storage features and keeping quality of the Redbor F1 hybrid
At room temperature, cabbage is stored for no more than 2-3 days, then it withers. Refrigerate for a maximum of 7 days. The leaves are placed in a container with water, like a bouquet, and covered with a plastic bag on top.
Freezing helps preserve this product for a long time.. The leaves are pre-washed and dried at room temperature, spread on paper or cloth napkins. It is advisable to cut off the stems and veins, leaving only the leaf blade.
What difficulties may there be when growing
When growing cabbage in the shade and in dense plantings, nitrates can form in the leaves. To reduce their number, at all stages of crop growth, biological products are used that increase immunity and reduce nitrate content.
Like many leaf crops, Redbor f1 withers and turns yellow on hot summer days. To prevent such phenomena, plants are provided with light shading during the midday hours.
Redbor cabbage dishes F1
It is most useful when fresh., since under the influence of high temperatures many of its valuable properties are lost.
Stuffed cabbage rolls
Leaves are doused with boiling water and thickenings are removed.. Place minced meat with half-cooked rice on the sheet and roll it into a tube. Next, put it in a mold, pour it with mayonnaise and bake it.
Salads
Various types of salads are prepared from kale, as it goes well with many vegetables and foods: tomatoes, cucumbers, boiled meat, potatoes, eggs, garlic, basil, green onions, etc.The dressing for this salad is sour cream, mayonnaise, flaxseed, olive or pumpkin oil.
Chips
The cabbage is cut into pieces (3 by 3 cm) and placed on a parchment-lined baking sheet.. Sprinkle with pepper, salt and olive oil on top. Place a baking sheet in an oven preheated to 100°C and dry until done, leaving the door ajar.
