Description of Onion Stardust
The Stardust variety is characterized by intensive distillation of the feather part in the first year of planting. To get full onions, sowing is planted in the second year. This is an early ripe culture, therefore, the sowing date falls on the first of May.
It is characterized by increased resistance to pests and diseases, unpretentious in care, loves a lot of light, does not tolerate a very cold climate. It undergoes shooting, therefore it multiplies in different ways.
Appearance
The Stardust onion variety can be recognized by external and other signs:
- the shape of the head is round, prismatic;
- the color of the husk is white;
- taste - specific onion with sweetness;
- severity - medium;
- the size of the bulbs is medium (weight from 40 to 60 g);
- green color - saturated green;
- feathers feature - wax coating;
- type of outlet - upright, lush;
- the pulp shade is white;
- neck - thickened;
- the fit of the scales is loose;
- the flesh is juicy.
Excellent taste deteriorates in one case - with insufficient watering during cultivation. Lack of moisture leads to bitterness.
Breeding
The Stardust variety is intended for propagation by seeds that are obtained from arrows. However, many farmers and gardeners use bulbs that are planted in the first year to produce green mass. Therefore, Stardust is permissible to propagate in 2 ways.
Ripening dates and productivity
Onions Stardust fully ripens in 58-60 days after planting the seed material. Accordingly, subject to the agrotechnical rules of cultivation. Thus, planting onions in early May, harvesting is carried out in early July.
The variety is characterized by high productivity. If the bulbs weigh 40-50 g, then with 1 square. m can be collected up to 3-4 kg (when growing on a feather), with a mass of heads of 50-60 g, yield per 1 sq. km. m is 4-6 kg. Onions belong to varietal, so there is the possibility of increasing the number of bulbs and their weight.
Properties and composition
White onion is characterized by a high content of nutrients, therefore it is used in folk medicine as a healing agent.
Composition:
- vitamins - group B (1, 2, 6), C, PP, E, kempferol;
- organic acids;
- glucose;
- glukinin;
- amino acids;
- flavonoids;
- volatile;
- micro and macro elements - boron, fluorine, copper, phosphorus, manganese, calcium, potassium, iron, sulfur, magnesium, sodium, silicon, rubidium, molybdenum, cobalt, chromium.
Due to its rich composition, Stardust has a mass of useful properties, which allows you to use the vegetable in the following cases:

Seed cultivation
Growing onion Stardust from seeds is the main method of reproduction, which involves the preliminary preparation of planting material. You can plant seeds immediately in open ground or in seedlings.
Pay special attention to soil mixtures - it must be fertile. To do this, it is better to purchase a special universal substrate in the store. But you can mix garden soil with peat and compost. Before sowing, be sure to disinfect the ground by warming it in the oven for 10-15 minutes.
Seed preparation
Seeds purchased at the store do not need to be disinfected - only germinate. But planting material collected at home requires special preparation, which is carried out in several stages:
- Calibration, i.e. rejection of material unsuitable for planting. Carefully inspect the grains, removing damaged elements. Place the seeds in warm water for 3-4 hours - healthy seeds will remain at the bottom.
- Seed disinfection is a mandatory procedure, as seeds can contain pests, their larvae and pathogenic microbes, due to which diseases develop. Disinfection is carried out with a weak solution of manganese for 20 minutes.
- To speed up the germination process, you can withstand the bulbs in a growth stimulator (drugs are sold in the store).
- Warming up. Pour the seeds with water, the temperature of which is +40 degrees. Stand for 30 minutes.
- Germination. The seed is wrapped in a gauze flap, placed on the bottom of a flat bowl (plate, saucer), filled with a small amount of warm water. Be sure to cover the container with cling film to create a greenhouse effect.
Until the seeds hatch, open the film daily to allow oxygen to enter. Otherwise, the seeds will be covered with mold. Ventilate for 20-30 minutes a day.
Container preparation
When the root system is formed in onion crops, elevated temperatures are excluded, since the root develops better with an average temperature regime. Therefore, containers for seedlings should have low thermal conductivity. Other requirements for the selection and preparation of containers:
- the size should correspond to the installation location (parameters of the windowsill, table);
- in the tank, make holes on the sides and on the bottom to create drainage (drainage of liquid);
- the container should be rigid, but light for ease of transfer;
- Before planting seeds, the tank is treated with antiseptic agents.
It is possible to plant seed material in plastic glasses, peat pots or cassettes, wooden boxes, plastic containers.
Planting seeds
Seeding time for seedlings: late February - early March. The landing process is step by step:
- put expanded clay pebbles in one layer in the prepared container;
- pour prepared soil on top (at least 15 cm), level the surface;
- make grooves with a depth of 1-1.5 cm with a distance between rows of 3 cm;
- sow seeds every 1-2 cm;
- sprinkle with soil mixture on top of 0.5 cm;
- spray the surface with spray water;
- cover with glass, a lid or plastic wrap;
- put the container on the windowsill on the sunny side for seedling formation (8-11 days is enough).
Care Rules
Until the first sprouts appear, do not forget to take care of the seeds - every day open containers for ventilation, periodically pour with warm, settled water, maintain the temperature within + 22-24 ° С. When seedlings form, remove the cover and no longer use it. Further care is as follows:
- Thin out if seeds are planted at a distance of 1 cm. Between them should be 2 cm.
- Air temperature should not be below + 18 ° С, above + 20 ° С.
- Water as you dry the substrate - the soil should not be too moist and dry.
- Onions Stardust is a photophilous plant. Daylight hours should be 12 hours. There is not enough lighting during growing seedlings, so install lighting fixtures (LED, phyto- or fluorescent lamps). The distance from lighting to seedlings is 22-25 cm.
- A couple of weeks after sowing planting material, fertilizers are applied. Top dressing is carried out every 12-14 days. What to use: chicken droppings (diluted with water in a ratio of 1:10), a mixture of 5 g of potassium chloride, 20 g of superphosphate, 10 g of urea, 10 l of water.
- After the appearance of three feathers, make pinching - cut the greens 2/3 of the entire height. Thanks to this manipulation, the seedlings will not break.
- About 10 days before transplanting into the open ground, seedlings are quenched, which makes it easier to adapt to new conditions. To do this, take out the boxes daily into the open air, starting from 10 minutes, gradually increasing the time to 2 hours.
Open transplant
Seedlings are planted on garden beds after 50-60 days. How is the transplant performed:
- Pour sprouts in the container with plenty of water. Carefully remove the seedlings by prying them with a spatula. After that, shorten the roots, leaving a length of 3-4 cm.
- Prepare the site - it should be well lit and calm. From the fall, add humus or compost to the beds. In the spring, level the surface, fill it with hot water and cover it with polyethylene for 3 days.
- Before planting seedlings, scatter wood ash over the site, dig holes. Between the rows leave 20-30 cm, the distance between the seedlings is 10 cm.
- Insert seedlings into the pits, sprinkle with soil, tamp.
- At night, if frost is planned, cover the seedlings with plastic wrap.
- To preserve the moisture level in the holes, it is recommended to put mulch under the bushes from any natural material - foliage, tops, weeds, hay, straw, sawdust.
Open field cultivation
Before planting, the bulbs are prepared - they are examined for suitability (there should be no damage, dark spots, signs of rot or overdry). Be sure to peel off the top layer of husk.
The bulbs are disinfected in a solution of potassium permanganate, then washed and dried. Immediately before laying on the beds, the top is cut off to accelerate the process of germination. It is recommended to cut off 1/3 roots before planting, and then place the heads in a mullein solution.
Site selection and preparation
The area for the white southeast should not be shaded and windy. Plantations in the form of bushes and trees nearby are excluded. The preferred soil is chernozem, sandy loam or loamy, but with neutral acidity. If the reaction is increased, the acid can be neutralized with lime and wood ash. Unsuitable soil - clay and heavy.
Place preparation rules:
- In the fall, immediately after harvesting, the site is dug up, which creates friability. Fertilizers are introduced into the soil - organic matter and minerals. For 1 square. m take 15 g of potassium chloride, 20 g of double superphosphate, 5 kg of humus, 8 kg of compost, 0.5 kg of ash. With very poor soil, chicken droppings are additionally used.
- In the spring, the garden is loosened, applying mineral fertilizers: ammonium nitrate (20 g per 1 sq. M), potassium chloride and superphosphate (the dosage is identical to autumn top dressing).
Landing process
After cultivating, smooth the surface of the garden with a rake, then dig holes in a specific pattern: row spacing - 20 cm, distance between bulbs - 7-10 cm, laying depth - 4 cm. Next, go directly to planting:
- Pour plenty of water into the wells, allow to completely absorb.
- Plant the bulbs, sprinkle with soil, compact manually.
- Sprinkle peat around the seedlings.
- For rooting as soon as possible, the next day, humate is introduced in liquid form, after which the area with the bulbs is mulched.
To grow sowing, heads are planted close to each other on green mass, so that you can get a high crop of feathers. m place 240-260 bulbs.
Further care
In the onion cultivation, Stardust is important not only the preparation and planting process, but also further care, on which the level of yield and germination of planting material depends to a greater extent.
Fundamental rules:
- Watering should be medium so that the soil does not get wet and does not dry out. Average humidification is once a week in a temperate climate and every 3 days under extremely hot conditions. Dosage for 1 square. m is 6-7 liters of water. Approximately from the beginning of July or the end of June, depending on the planting period (this is 2 weeks before harvesting), humidification is completely stopped.
- Top dressing carried out three times per season. The first time organic and mineral fertilizers are applied during the growth period of the root system. Urea or nitrate, slurry or chicken droppings are used. The second time a complex composition is required for the development of green mass - infusions of herbs, wood ash, Nitroammofoska and other specialized preparations based on minerals (especially phosphorus, nitrogen and potassium). For the third time, top dressing is needed at the stage of head formation, therefore, superphosphate, potassium monophosphate, wood ash are used.
- Weeding and cultivation. Procedures are carried out after watering as weeds grow.
- Mulching not necessary, but desirable, as it allows to reduce the amount of watering, prevents the growth of grass.
Pests and diseases
The Stardust variety is usually not exposed to diseases and pests, but under adverse conditions this is possible. Diseases and infecting insects:
- Downy mildew or peronosporosis. Signs - wilting greens, the formation of spots of light shades and plaque on the feather part. With progression, the bulb is also affected. This fungal disease is treated with fungicidal agents, but only if onions are grown on turnips. When the target is a pen, other methods are used. For example, watering is completely stopped, which eliminates further decay. Potassium and phosphorus are introduced into the soil, damaged elements are destroyed.
- Gray rot manifested by putrefactive formation at the cervical base and on the bulbs. The treatment is identical to the previous one, since it is a fungal disease.
- Bacteriosis - also a fungal disease in which the head rots, an unpleasant odor forms. The treatment corresponds to the two previous options.
- Onion fly. Symptoms - damage to the feathers, as larvae are deposited in them. The aerial part undergoes drying and yellowing, the bulbs undergo rot. For treatment, chemical preparations (Aktara, Mukhoyed, etc.) or folk remedies (wood ash, tobacco dust, saline solution) are used.
- Onion thrips. Feathers change color, fade.The treatment consists in destroying the affected bulbs and repelling the pest with tobacco dust, ground black pepper, naphthalene.
As a prophylaxis against all pests and diseases, treat the soil and seeds with disinfectants, carefully inspect the bulbs before planting.
Harvesting and storage
The method of harvesting depends on the purpose of cultivation. If you need a pen for your own consumption, it is cut off as it grows. If the greens were planted for sale, the plant is not cut, but torn out along with the bulbs, and then cleaned of dirt.
Rules for the collection and preparation for storage of heads:
- The weather should be sunny and warm, the presence of wind is welcome, as the bulbs are laid out on the beds for drying.
- Try not to pull the root crops out of the ground with effort - this will damage the neck.
- Use to pick a pitchfork or a shovel, which dig up the vegetable, then gently pull on the tops.
- For 1-2 days, spread the heads on the bed, then crush the remaining soil, clean from the upper scales.
- The next step is continuous drying in a ventilated area. Onions can be laid on the surface of the floor, table, but be sure to turn the heads 1-2 times a day. The best option for drying is to bind the bulbs in small bunches, hang. Drying time - 10-20 days.
- Next, cut the tops so that the neck length is 4-5 cm.
- The roots are also trimmed a little.
- After that, sorting is carried out - heads with damage, larvae, spots and other defects are rejected. Very small elements are also deposited here. This onion is not used for long-term storage, it is consumed in the near future.
Storage conditions:
- Onions remain warm for a long time, as they are not exposed to high humidity. The optimum temperature is 18-22 ° C. Bulbs are placed in wicker baskets, boxes, cardboard boxes, in the pantry. If you do not cut the tops, you can braid the braids that are suspended.
- In the cool - at a temperature of 0 to + 3-4 ° C - vegetables must be laid in plastic or wooden boxes, sprinkled with sand, sawdust. The best place is a glazed balcony / loggia, cellar, basement.
5 helpful tips
Experienced gardeners are happy to share their own experience, so listen to their recommendations:
- For planting, use only high-quality material, be sure to disinfect and follow all the rules of preparation.
- For rapid germination, the temperature of the soil should not be less than 10 degrees.
- Always disinfect the soil to destroy pest larvae, weed roots. To do this, you can water the beds with boiling water or irrigate with a solution of manganese.
- Do not plant seeds and seeds too deep - this will slow down or even stop growth.
- When the pen is distilled, watering is performed more often than when grown on the head.
Reviews gardeners
Karina, 32 years old. I love Stardust onions for its unique taste, so I add it exclusively to salads. It is not very sharp, there is a kind of onion sweetness, and juiciness allows you to make cutlets very tasty. Recomend for everybody.
Georg, 44 years old, a summer resident. Our family grows Stardust in the country. In principle, the variety is not whimsical, it does not require special care, except for watering. It happens that we do not always come to the country. So, because of this, the onion turns out to be bitter (there is not enough moisture, which I later subtracted). To prevent this from happening, we now always put mulch under the bushes immediately after watering with a layer of up to 10 cm. It perfectly retains moisture even in drought.
Natalie Vernikovskaya, 38 years old. I grow onion Stardust every year in my garden, because I use it not only for food, but also for medicinal purposes. Now there are so many recipes for various diseases, but especially it saves you with colds and prevents flu during epidemics. For planting, I use both seeds and seeds. Onions of feathers grow on one part of the beds, and on the other for the heads.
