Pak Choi is a traditional Asian culture, which has recently become popular with European and American gardeners. It is suitable for cultivation in Russia. Chinese cabbage is unpretentious, not particularly heat-loving, does not place high demands on the quality of the substrate. At the same time, it is characterized by early maturity and good productivity, it is very useful for health.
What does Chinese cabbage look like?
As you might guess, the homeland of Chinese cabbage is China. It is also very popular in Korea and Japan. In Asia, it has been grown for more than five thousand years. The culture is known by the nicknames "pak-choi" ("horse ear") and "mustard cabbage." Do not confuse it with Peking cabbage, these are close "relatives", but still different, from the point of view of nerds, culture. A kind of cabbage pak choi was considered by Carl Linnaeus. But modern botanists believe that it is more like a turnip.
Peking cabbage outside of Asia is known much better than Chinese. Therefore, they are often confused. The main difference between them is that the first forms a head out. Her leaves are much paler, almost white, wrinkled, with corrugated edges. The taste of Chinese cabbage is sharper, it gives a crop much faster.
The plant looks quite unusual. This cabbage does not form heads of cabbage. It would be very difficult to distinguish it from lettuce or spinach, if not for the characteristic thickening at the base of the stem. In height, the “rosette” of leaves reaches 0.5 m, the average diameter is 35-40 cm. Petioles of white or salad color are pressed tightly against each other, forming something that looks like an onion, so the plants are quite compact. The diameter of this thickening most often does not exceed 5-10 cm, weight - 100-250 g. Practice shows that varieties with greenish stalks are more resistant to stem.
Leaves of various shades of green with a bluish-gray tint, whitish veins. They are smooth to the touch. The surface can be either almost flat or noticeably bubbled.
Edible in Chinese cabbage and leaves, and petioles. Pfor the first time, they taste like slightly bitter spinach or celery, and the second are something between asparagus and leaf beet, but sharper. At home, in Asia, salads are most often prepared from it, consumed fresh. Other greens, eggs, green peas, corn, onions, garlic, radish, even ginger and tangerines are added to Chinese cabbage. Even in Korea, a kimchi snack (spicy sauerkraut with ground hot pepper) is very popular. You can replace the usual Chinese cabbage in soups, prepare side dishes from it. During heat treatment, it changes the taste to sweet, without losing its characteristic sharpness. But they boil, fry and stew it for a very short time - the leaves are extremely delicate.
One of the indisputable advantages of culture is early maturity. Cabbage can be cut just 20-25 days after the transfer of seedlings to the garden. And in greenhouses and hotbeds - 2-3 weeks after emergence. Accordingly, even in a temperate climate, you can get 2-3 crops per summer. Also, its unpretentiousness, cold resistance, and stably high productivity contribute to its popularity among Russian gardeners. We must not forget about the health benefits.
The optimum temperature for its cultivation is 15-20 ° C. If it rises to 25 ° C and above, sunburn on the leaves is possible. The culture is cold-resistant (tolerates frosts to -5-7 ° C), but this applies to adult plants. If the seedlings are planted too early, stalking is almost inevitable, especially in conditions of long daylight hours.
Perhaps the only drawback of the plant is that when it reaches its maximum size, the leaves and petioles are very rough, hard fibers appear in them. Therefore, at home they prefer to cut out sockets that have reached a height of 15-20 cm. Their greens are much more tender and juicier. After cutting, a new shoot is formed quite quickly.
Chinese cabbage is characterized by a high content of vitamins (A, C, E, P, PP, group B) and essential amino acids, especially lysine, in combination with low calorie content (13 kcal per 100 g). With regular use in food, it is an effective prevention of atherosclerosis, helps strengthen immunity, get rid of chronic fatigue syndrome, increase mental and physical performance, and normalize blood pressure.
Nutritionists recommend it to those who want to get rid of extra pounds and normalize the gastrointestinal tract and liver. There is research evidence that Chinese cabbage helps prevent the development of tumors, including malignant ones, due to the presence of glucosinolates, which give it a bitter taste. It is also rich in magnesium, potassium, phosphorus, iron, antioxidants, fiber and starch.
The high content of vitamin A and folic acid, which prevents abnormalities in the development of the fetus, makes Chinese cabbage very useful for pregnant women.
In Chinese and Tibetan folk medicine, Chinese cabbage juice is widely used, especially in combination with egg white. It is used to heal wounds, ulcers, inflammations, burns.
There are contraindications. Chinese cabbage is not recommended to be included in the diet for diabetes. The metabolic process in this case is already impaired, it can cause additional hormonal disruptions and even to whom. Also, this cabbage is not recommended for problems with the thyroid gland. With excessive consumption, it can cause problems with the absorption of iodine.

Landing procedure and preparation for it
Chinese cabbage can be grown both in seedling and from seeds. Practically any garden crops are suitable for her as predecessors, except for other varieties of cabbage, radish, daikon, radish, rutabaga. If there is a goal to independently collect seeds, Chinese cabbage is planted away from Peking. With other "relatives" she is not cross-pollinated.
A bed for planting is prepared in the fall. The culture is not particularly picky about the quality of the soil, but it is advisable to increase the fertility of the substrate by adding humus or rotted compost (10-12 l per 1 p / m) during digging. The acid-base balance of the soil is neutral or slightly acidic. The only thing that categorically does not suit her is a heavy peat substrate. Ideal option is sandy loam or loam.
The plant tolerates partial shade and shadow, it practically does not affect productivity. But open areas of culture will not work. If the summer is hot, sunburn is almost inevitable.
To save space on the site, Chinese cabbage can be planted between rows of cucumbers and tomatoes. Growing up, these plants will create a kind of "canopy" that protects it from direct sunlight.
Chinese cabbage, like other garden crops native to Asia, reacts negatively to fresh manure. Of the fertilizers, superphosphate and potassium nitrate are useful to her (for a tablespoon per 1 m²). You can replace them with wood ash. Dolomite flour or egg shells crushed to a powder state are additionally added to acidic soil. They saturate the soil with calcium, which any cabbage loves.
Seedlings are planted in the second decade of March. The culture does not tolerate picking and transplanting very well, so they are sown several in peat pots with a diameter of 8-10 cm, then to be transferred to the bed together with the tank. Seedlings develop quickly, transplants are carried out already 20-25 days after emergence. By this time, seedlings should have 4-5 true leaves. Between the rows leave about 40 cm, the interval between plants is 35-50 cm.
Before planting, the seeds are heated for a quarter of an hour in a thermos with hot (50 ° C) water, then literally for a minute they are immersed in cold. To increase germination, they are soaked for 10-12 hours in a solution of a biostimulant (Epin, potassium humate, succinic acid, aloe juice). To prevent the development of fungal diseases - 15-20 minutes are etched in a solution of biofungicide (Topaz, Baikal-EM, Alirin-B, Fitosporin-M).
The containers are filled with any purchased substrate for seedlings, adding a little crushed chalk or wood ash. Seeds are planted, buried by 2-3 cm. The pots are turned into greenhouses, covered with glass or film, kept in a dark place until emergence. Then they are transferred to the windowsill of the east or south window. The optimum temperature is 18-22 ° C during the day and 14-18 ° C at night. Chinese cabbage is watered often, but sparingly, constantly maintaining the substrate in a slightly wet state, but not turning it into a swamp.
To make it easier for plants to adapt in a new place, they begin to harden about a week before planting. First, the seedlings are left in the open air for a short time, then gradually extend the time spent on the street to 12-14 hours. More experienced gardeners recommend stopping watering 4 days before planting, and moisten the soil well half an hour before it.

Wells are also well shed with water. At the bottom put a handful of humus, a couple of pinches of wood ash and a little onion husk (it repels pests well).While the planted seedlings do not start growing, arcs are installed above the bed, covering it with any white covering material passing through the air.
When planting seeds directly into the ground about a week before the procedure, the bed is shed with a dark pink solution of potassium permanganate and tightened with a film. Soil before and after planting seeds of Chinese cabbage must be well moistened.
Between the rows leave 30-40 cm. Seedlings appear after about 7-9 days, if the seeds are deepened by about 1 cm. Prior to this, the bed is covered with polyethylene, white agrospan, spanbond. Sprouts are watered twice a week and only with warm water.
In the phase of the second real leaf, the plantings are thinned out, leaving 20-25 cm between the plants. When the third leaf appears, humus is added to the roots. Practice shows that in this case, plants develop faster.
"Extra" seedlings are cut with scissors or pinched near the ground. To plant more or less uniform, the seeds are mixed with sand.
Chinese cabbage is a short daylight plant. So that it does not go into the arrow, it is planted either in the middle of spring, or near the end of summer. May and June are the wrong time if the selected varieties are not resistant to flowering.
Crop Care Tips
Chinese cabbage is extremely unpretentious. The crop ripens very quickly, so all that is required from the gardener is weeding the weeds, loosening the beds, fertilizing and watering. The latter is most important. Like any cabbage, pak-choi is a moisture-loving plant.
The root system of Chinese cabbage is superficial, the roots go into the soil by a maximum of 15 cm. Therefore, sprinkling is the best way to water it. Pouring water under the base of the outlet is undesirable - the bare roots dry out quickly. If the street is at the optimum temperature for the culture, watering is carried out every 2-3 days, spending about 20 liters of water per 1 m². In the heat, Chinese cabbage is watered daily or even twice a day. In the evenings, you can additionally spray the leaves. Mulch will help retain moisture in the soil. She saves time on weeding. Any material other than peat and fresh sawdust is suitable - they strongly acidify the soil, which often leads to the development of keel.
If it rains heavily in summer, plants may begin to rot. To protect the bed from excess moisture, you can use a film or a covering material stretched over the arcs.
The vegetative period of Chinese cabbage is very short, therefore any mineral fertilizers, especially nitrogen fertilizers, which contribute to the accumulation of nitrates in the leaves and petioles, are completely excluded. For early-ripening varieties, two top dressings are sufficient, for mid-ripening - three. The first is carried out 5-7 days after transplanting seedlings into the ground or when 5-6 leaves are formed in seedlings in the garden. The second and third (if necessary) - with an interval of 10-12 days. Chinese cabbage is watered with infusion of wood ash, nettle leaves, dandelion, and other weeds. From store fertilizers, any means based on vermicompost is suitable. The consumption rate is about a liter per plant.

Chinese cabbage in a greenhouse
Chinese cabbage seeds germinate already at 4-5 ° C, so it can be sown in the greenhouse in spring. The gardener will have time to harvest before the time comes to plant cucumbers, tomatoes, eggplants, and other crops. If the greenhouse is heated, it is possible to sow seeds in the first ten days of March, if not, in early April. They dig the soil in the fall, make humus, and spill it with 2% copper sulfate or a bright pink solution of potassium permanganate. For additional disinfection in the greenhouse, you can burn a small piece of sulfuric block.
When planting, they adhere to the same scheme as for open ground. The substrate before and after is well moisturized. Before emergence, a temperature of about 20 ° C is desirable. Then for about a week it is lowered to 10-12 ° C. Further, before harvesting, the optimal indicator is 16-18 ° C.
The growing seedlings are thinned twice at weekly intervals, leaving between the plants 10-15 cm first, then 30-35 cm. Watered as the topsoil dries. You can do without feeding. Or use an infusion of wood ash.
Chinese cabbage planted in the early spring in the greenhouse almost never suffers from diseases and pests. For most of them it is still too cold, the larvae, eggs and spores of the fungus simply do not have time to "wake up" from hibernation.
Chinese stalk cabbage at home
The base of a Chinese cabbage outlet about 5 cm high can be used again, getting greens at home after cutting. Another option is to plant the rooting plant in the ground and collect another 2-3 crops. The fresher the plant and the denser the "bulb" at the base, the better.
The "bottom" is placed downside down in a deep container with water at room temperature so that only its very base touches it. Previously, "planting material" is examined - there should be no traces of rot, mold, pest damage. The container should be kept in a cool place, but not in the refrigerator, water should be changed daily. A lot of light does not need Chinese cabbage, but the heat is very undesirable. She gives roots quite quickly, literally in 3-4 days. Fresh greens will soon appear.
After this, the plant can be carefully, remembering that the root system of Chinese cabbage is extremely fragile, transplanted into a container filled with any universal soil for indoor plants with the addition of sifted wood ash or crushed chalk. At the bottom of the pot, a 2-3 cm thick drainage layer is required. Watering after transplantation is resumed only when the plant begins to form new leaves.
Hold the pot on the windowsill of the window facing north, northwest. When the street is at a suitable temperature, you can take it to the balcony. If a flower arrow appears, it is immediately cut off.
Chinese cabbage is watered sparingly, but often, every 2-3 days. It is quite possible to do without top dressing. In summer, in order to create the required short daylight hours, it is advisable to cover the plant for 12-14 hours with a dense black plastic bag. Otherwise, especially if the desired temperature is not maintained, an arrow forms quickly.

Culture-specific diseases, pests and their control
The vegetative period of Chinese cabbage is short, immunity is quite good in comparison with the "relatives". Many pests are scared away by the essential oils contained in the leaves in high concentrations. But this culture is not completely immune from attacks of pathogenic fungi and insects.
Of the pests for Chinese cabbage the most dangerous are:
- Cruciferous flea. Pests and their larvae feed on plant tissues, literally in a couple of days turning the leaves into something that looks like a colander. A week after planting or two after emergence from the seeds, the soil on the bed is sprinkled with a mixture of ground pepper, tobacco chips and sifted wood ash, taken in approximately equal proportions. If the flea is still small, plants are sprayed with tinctures of tansy or celandine. In the event of a mass invasion, Foxim, Aktaru, Fosbezid are used.
- Caterpillars of butterflies and white scoops. Pests eat leaves from the edges. Very quickly, only petals and veins remain from them. Peak activity of adults occurs in May. At this time, not far from the garden, you can place special pheromone or homemade traps (deep containers filled with diluted sugar syrup or honey diluted with water). At night, butterflies fly into the light - this feature can also be used. Some gardeners simply cover the bed with a fine mesh net - in this case, the butterflies physically cannot lay eggs on the leaves. In the event of their mass invasion, Lepidocide, Bitoxibacillin are used to combat adult individuals. Larvae are destroyed by Actellik, Tanrek, Mospilan.
- Cabbage fly. Larvae damage the roots of the plant, penetrate into the stems through them, eating long “tunnels” in them. For prevention, plants and soil are sprayed with infusion of onion or garlic gruel. To combat the pest use Mospilan, Fury, Fufanon.
- Aphid. Small greenish insects cling to the leaves, feeding on plant juices. Small beige spots are formed on them, clearly visible in the lumen. For prevention, cabbage is sprayed 2-3 times a week with infusions prepared from any sharply smelling herbs. You can also use onion and garlic arrows, tomato tops, lemon peel, mustard powder and so on as raw materials. They will help if the appearance of the pest is noticed on time. The frequency of treatments is increased to 3-4 times a day. In the absence of the desired effect, any general-acting insecticides are used - Inta-Vir, Iskra-Bio, Confidor-Maxi, Admiral.
- Snails and slugs. Pests eat large holes in leaves and petioles, leaving a layer of sticky plaque casting silvery on the surface. Their massive invasions are extremely rare, so it’s quite possible to get by with folk remedies. The easiest method to combat slugs is manual collection. Deep tanks are also dug into the ground, filling with beer, fermented kvass, slices of cabbage. Any spicy herbs, marigolds, calendula, chamomile, and lavender are planted along the perimeter of the garden. The base of the stem is surrounded by a "barrier" of spruce needles, sand, chopped walnut or egg shells. "Heavy artillery" against slugs - Meta, Thunderstorm, Sludge preparations.

- Aphids - one of the most "omnivorous" garden pests
- The shelf life of Chinese cabbage, damaged by slugs, is sharply reduced, it also looks not very appetizing
In order to avoid fungal diseases, as a rule, preplant seed treatment in a solution of a fungicide of biological origin is sufficient. The causative agents of rot, bacteriosis, downy and powdery mildew do not tolerate copper compounds. Observance of the interval between plants is very important - with thickened plantings, spores of the fungus spread much faster.
For prevention, irrigation water can be replaced once a week with a pale pink solution of potassium permanganate. The soil in the garden is sprinkled with crushed chalk, colloidal sulfur, the plants themselves are dusted with sifted wood ash, sprayed with water diluted kefir or whey (1:10) with the addition of iodine (drop per liter). It is extremely undesirable to use any chemicals to fight against fungi - because of the short growing season, this will certainly affect the quality of the future crop. If there is no choice, preference should be given to fungicides of biological origin.
The greatest danger to Chinese cabbage is keel. On the roots of the plant, ugly growths form, the aerial part dries. It is already impossible to cure him, it remains only to tear and burn. The best prevention is crop rotation. After any Cruciferous crops, the same family can be planted no earlier than 4-5 years later.
Photo gallery: symptoms of diseases that Chinese cabbage can suffer from
- White rot on cabbage resembles peeling oil paint
- Dry rot most often develops during storage, but cabbage in the garden is not safe from it.
- Mucous bacteriosis makes cabbage completely unsuitable for eating
- Cabbage leaves affected by peronosporiosis turn brown quickly and dry
- With powdery mildew, the leaves from the inside are covered with a continuous layer of plaque, similar to sprinkled flour
- Cure cabbage infected with keel. impossible
Harvesting and storage
Harvest can be cut as soon as there are 9-10 leaves in the outlet. It is such a young Chinese cabbage that is preferred in the homeland, in Asia. Then you can gradually tear off the leaves as they grow. Another option is to cut off the sockets completely when their height and diameter have reached the size characteristic of the variety. But in this case, it is important not to be late, the leaves of overripe Chinese cabbage quickly coarse.
Most often, greens are used fresh. But if you wish, you can save Chinese cabbage for 2-3 months. To do this, plants are dug up together with the roots and "transplanted" in boxes with wet sand or peat. The same is done if cooling is expected to reach -10 ° C or lower, and the crop has not yet ripened. Store outlets in the cellar at a temperature of 2-5 ° C. Good ventilation and high humidity (70% or more) are also required.
Fresh leaves are stored in the refrigerator. To do this, they need to be separated from the "onion", rinse, blot excess moisture with a paper towel and put in the refrigerator, putting, like a bouquet, in a container of water and covering with a plastic bag on top. You can also wrap them in a damp cotton cloth. In such conditions, the leaves do not lose freshness for 7-10 days.
Somewhat less commonly, freezing and drying of leaves of Chinese cabbage is practiced. In Asia, it is salted and pickled.
There is nothing difficult in growing Chinese cabbage in a garden plot. This crop is surprisingly unpretentious and even in conditions of a temperate Russian climate can produce several crops per season, including when grown in open ground. Pak-choi ripens much earlier than other greens, which allows you to pleasantly diversify the menu in the spring. Her taste is very good, and in terms of health benefits, she surpasses many varieties of cabbage familiar to gardeners.
