To get a good harvest of onions, many gardeners as a planting material use sevok grown from seeds. Simple preparation and processing before planting will help to get friendly shoots and create protection of the culture against pests or diseases. The measures taken will also affect the process of vegetation and the formation of the head.
Before planting and sowing in open ground, onion seeds should be prepared in a special way - disinfect or pickle, cut the tip, process with phytosporin from the fungus or to reduce arrowhead.

Do I need to cook onion seeds before planting in open ground
Seasoned gardeners recall the times when they were not even talking about preparing onions for planting. It was believed that the onion - a plant enough unpretentious, does not require special attention. Was bypassed unless the bulkhead to remove damaged onions.
In addition, each stage of the preparatory process gives the planting material preferential qualities:
- growth promotion;
- destruction of harmful bacteria by disinfection;
- strengthening immunity (resistance to a number of diseases and pests);
- turnip rotting prevention;
- increase resistance to weather disasters.
Lifting a generous onion crop is not only dependent on proper care. The lion's share of success depends on the quality of the set-up preparation for disembarkation.
How to do presowing treatment of sevka spring
You can strengthen the immunity of the seed for resistance to pests and diseases. by soaking. There are quite a lot of recipes for presowing procedures, you can easily make and choose a convenient option.
Among the popular components:
- salt;
- potassium permanganate;
- copper sulphate;
- baking soda;
- ammonia;
- Birch tar.
The main enemy of the bow is onion fly. To prevent its invasion of the beds will help treatment of sevka salt solution. The same way will save culture from thrips and ticks.
And in the fight against fungal spores has proven itself potassium permanganate. Soaking in a weak solution will help destroy the microorganisms on the planting material, the main thing in time to drain the solution.
For fast growth, various growth promoters are used. Pre-treatment accelerates the germination of shoots for 3-6 days. Among the effective means - solutions of zircon and humate, "Energen".
Correct processing
During its storage, it is necessary to observe temperature conditions and not to allow an increase in the humidity of the air in the room. Good ventilation or regular ventilation. will prevent damage sevka. In the spring, just before planting, the bow undergoes complex processing.
From pests and diseases
Sevok for planting purchased or used your own, grown from the seeds of chernushki. It is impossible to visually determine the presence or absence of fungal spores and other harmful bacteria in it, therefore it is recommended decontamination procedure.
There are a lot of drugs and various means capable of coping with this task. Each of them has its advantages and disadvantages, which must be taken into account before use.
Many gardeners use the old proven method of processing planting material - soaked it in a weak solution of potassium permanganate for 20-25 minutes. Another method involves the use of nitrate (2-3 gr.), Which is diluted in a bucket of warm water.
Improve immunity and get rid of harmful bacteria will help ordinary salt. In a bucket of water, 5-6 tablespoons of salt are diluted, after which seeding is dipped for 4-5 hours. Slightly less concentrated salt water is poured over the soil under the beds for the purpose of disinfection.
Onions will protect against fungal infections drug treatment Phytosporin. In a bucket of water diluted 35 grams. Phytosporine and immersed in liquid prepared heads for 20-30 minutes.
To stimulate growth
To sevok quickly grew and gave a good harvest before planting it is recommended to process it with growth stimulants. The most affordable and popular way is to use wood ashrich in potassium and natural antiseptics.
Procedure in addition to accelerating growth prevents rotting material in the ground. Need to dilute in 5 liters of water 250 grams. ash, then immersed in a solution of the bulbs for 10 minutes. Next, for 2-3 hours you need to dry them.
Effectively copes with the task of the drug Epin-Extra. In the heated water to 50 degrees add 1 capsule. Soaking heads is 10-15 minutes. You can also use other tools: Biostim, Silk. The solution is prepared in the proportions indicated in the instructions.

To reduce arrowhead
Warming up necessary to prevent early arrow formation. Some gardeners carry out the procedure in the sun (at a temperature not lower than 20 degrees).
Others send sevok (in a cardboard box) to the battery, where under the influence of heat no more than 40 degrees planting material is kept for about 10 hours. It is important not to overdo onions and overheat.
If there is no time for warming up, and the landing time has already arrived, you can fill the onion with hot water (about 50 degrees) for 15 minutes, after which you must pour cold water. Such express processing will not completely eliminate the release of arrows, but will significantly delay the time of their formation.
-
- Sevka heated in the sun
-
- In hot water, warming up is carried out directly in the grid.
When soaking is recommended to immerse the onion in the solution in the grid. On top of it you need to lay out a small weighting agent, so that the sevok does not pop up. It is impossible to use too heavy objects, as they will damage the integrity of the heads, which will spoil the planting material.
Preparation before processing
The preparatory process consists of the following steps:
- sorting of planting material;
- drying;
- warming up;
- soaking and disinfection;
- drying
When sorting, it is important not only to remove the damaged onions, but also to sort the material suitable for planting. in size.
Large turnips are planted first on the beds, after them medium ones are sent to the soil, and the smallest ones germinate the fastest, so their turn is the last.
Planting on the bed sevka approximately the same diameter, is provided uniform development of shoots and forcing pen. In turn, the roots will be formed of approximately the same size, which is convenient for subsequent storage.
After soaking procedures, it is important to wash the chains in clean water, changing it 2-3 times. Few people mention this fact, and inexperienced gardeners miss this stage.
Do I need to trim the tip of the onion stub before planting
For large plantations, this is difficult to cut due to large volumes. Head apex removal accelerates the germination of the shoot and creates favorable conditions for a good growing season.
In addition, the correct pruning makes the soaking procedure more efficient, it is much easier for the solution to penetrate between the head flakes. Careful preparation virtually eliminates unpleasant surprises during the cultivation of bulbous culture.
When performing trimming, do not remove too large a fragment of the top. This will cause the planting material to rot, or it will not allow the onion to release green.
Methods of preplanting onion cutting
When growing onions on a feather with large heads 1/3 of the top cut off. This makes it easy to extract the green when it reaches the desired height. If the goal of agrotechnology is to obtain a root crop, then it is worth cutting off only the tail, without hitting the white skin.
Some varieties (for example, Msergey) are cut on both sides: and the top and bottom. This is done to accelerate growth and the rapid formation of the root system. Such a manipulation gives the result literally the next day, when the process of growth of the shoot begins. On the dry bottom, the roots are formed much later.
Having weighed all the pros and cons of the preparation of seeding for planting, it is safe to say the fact that these procedures are necessary. The cost of time and money will require a minimum, and the quality of the bulbs and the entire crop increases significantly.
In addition, it is possible to develop your own recipes for the treatment of planting material, to share them and the results of use with all gardeners.If the purpose of cultivation is to get a feather (greenery), then the preparation is often limited to sorting.
