Growing onions in sawdust on the windowsill is quite possible. Planting it in a bag on the greenery of the house allows you to get good results. But in any case, it is important to know everything about the proper cultivation of sevka per feather in sawdust and about full-fledged planting care.
What conditions are necessary?
In order for the onion in sawdust on the windowsill to please with full development, you will need:
There are almost no strict requirements for containers and planting material. The main thing is that they fit and look good.
When planting in a bag on greens, in addition to the bag itself, again, you need a good substrate and high-quality planting material. The process itself does not take much time and effort. However, it must be thoroughly studied in advance.
Prepare
Tara
Any squat plastic box can become a container. In its bottom, holes are formed to drain excess liquid. Before disembarking, the tank is rinsed with an aqueous solution of soda. Then it is washed with an unsaturated solution of potassium permanganate. When using the package, there is no special need for drainage holes, they are made only 1 or 2 pieces; the bag itself is inflated and tightly tied so that carbon dioxide is preserved inside.
The size of the container is selected taking into account the number of planted onions. It is necessary to check that the heads are tightly closed. The preference for low tanks is due to the fact that they save space and use less sawdust.
Do not take containers that have previously been in contact with toxic substances. They are unlikely to allow you to get a good harvest, and its quality will be in question.
Sawdust
A good nutrient substance will be sawdust obtained from hardwood. It is best to buy them in a flower pavilion or in a pet store. The substrate must be shed with boiling water, in which permanganate is dissolved. This will disinfect it and reduce the acidity. Additionally, ammonium nitrate diluted in water at a concentration of 0,5% is used, since thanks to nitrogen, the feather will develop faster.
Some sources write that sawdust from conifers is also suitable. It is perfectly acceptable to use those that are sold as bedding for pets. But sawn material from chipboard and other boards cannot be used, it will be toxic. This applies even to those designs that contain a little glue and varnish.
Planting material
For planting sevka, it is most preferable to use early-ripening varieties. Good results, according to experience, demonstrate:
If the landing is planned in the winter, it is advisable to buy planting material in advance. If possible, you should avoid buying preservative-treated onions. Although it is stored longer, the green yield will be quite small. A test copy is cut and they see how many green sprouts it will give. It is best to take onions that are not too large, with several points of growth; it is more correct to completely refuse to purchase it in a supermarket or at a wholesale base.
Before planting, the onion is freed from the husk. The top is cut off by about 1 cm. This pruning will allow you to get more green shoots.
Soaking in potassium permanganate or “Fitosporin” is useful, and if both are not available, then ordinary kitchen salt will do. Sawdust cultivation is a kind of analogue of a warm garden bed.
Landing
It is not so difficult to properly plant onions in sawdust at home. The planting material itself is placed tightly. It should be deeply buried. The gaps are sprinkled with dry sawdust and the container is placed where there will be no drafts. The thickness of the sawdust layer is approximately 2-3 cm; they should not overlap the fruits themselves.
It is required to choose a well-lit place. But an excess of direct sunlight is contraindicated. Sawdust can only be used once. When planting in a bag, the bow is not deepened, but simply installed tightly. The substrate layer must be at least 2 cm.
Care
When growing, onions should not be watered too often. For the first time, it is watered directly at planting. Then wait 6-7 days. This regularity continues to be followed. If the air is relatively humid (more than 60% in relative terms), then you can reduce the frequency of watering and conduct them 3 times a month; overflow leads to rotting of growth points, and it is impossible to water at all just before cutting the feather.
To grow onions in sawdust on a feather, you need active lighting. Optimal daylight hours are 12 hours. To maintain it, phytolamps or devices replacing them are needed, which must be placed vertically. Any other placement will damage the sprouts. Feeding is almost never required.
The addition of hydrogen peroxide helps disinfect plantings. It is diluted in water at a concentration of 3%. Noticing that the feather has acquired a light green color, it must be sprayed with calcium nitrate; its concentration is maintained very carefully. As soon as the feathers grow to 20 cm and above, they can begin to be harvested. Cut them off, moving to the middle of the cut on the turnip.
You can stably get a crop due to plantings with an interval of 15 or 20 days. Each onion turnip can yield 3 or even 4 feather harvests. More precisely, it can only be said with reference to the variety. This method does not require a significant investment of time and money. In return, you can get safe and high-quality food that does not contain questionable substances.
There are a few more subtleties that allow you to achieve a good result. Before soaking sawdust, it is useful to add activated carbon there. It is sometimes replaced with wood ash. It is best to keep the plants on the kitchen windowsill. There are no more special nuances.
