Onions are considered an undemanding agricultural crop. Most novice gardeners mistakenly think that you can harvest a good vegetable crop without much effort. This leads to a common problem – shooting, which does not allow you to get strong heads at the end of the season. Experienced gardeners recommend paying special attention to pre-sowing preparation. To get a good harvest, you can soak the onion in potassium permanganate before planting. However, this procedure must be carried out correctly in order for it to be beneficial.
Potassium permanganate is an available antibacterial and antifungal agent.
Why process onions before planting
Soaking onions in potassium permanganate before planting is necessary to prevent damage to it by bacteria and fungi. When purchasing seed, there is usually no certainty that it was stored correctly in compliance with all necessary requirements. And any violation of the mode of maintenance of the sevka leads in the future to the loss of the crop.
The lack of soaking at the stage of onion preparation for planting leads to a low percentage of marketable fruits, since the main part of the seedlings dies during the growth process. At the same time, the size of the heads is not more than average, and the likelihood of crop rotting during storage increases significantly.
Potassium permanganate, or potassium permanganate, is a strong antibacterial and antifungal agent. And pre-sowing soaking of onions in a solution of this substance allows you to destroy most types of pathogens that live on its surface. This increases the immunity of seedlings at the initial stage and enables them to fully develop.
The benefits and harms of potassium permanganate for onions
The use of potassium permanganate for the treatment of sevka has its advantages. But this component also has certain disadvantages that must be taken into account so as not to harm the bow.
Potassium permanganate is a chemical that should be handled with gloves
Useful properties of potassium permanganate:
- protects against the development of fungal and bactericidal diseases;
- increases the resistance of seedlings to adverse factors;
- maintains immunity at a high level;
- prevents the development of wintering larvae of pests.
Disadvantages:
- inhibits the development of not only pathogenic, but also beneficial microflora;
- increases soil acidity.
Soaking sevka in potassium permanganate, although it gives positive results, the procedure should be carried out correctly. Exceeding the recommended dosage of the use of this component will cause a burn of the planting material. This leads to the fact that seedlings cannot grow a powerful root system, which means that their development slows down.
Preparation of the seeding for planting
The volume of the future harvest and the quality of the fruits directly depend on the pre-sowing preparation. The procedure consists of several main steps that cannot be ignored.
Initially, planting material should be sorted out, and all specimens that have signs of damage and mechanical damage should be discarded.
To speed up the germination of the sevka, you can cut off the dry top by 0,2-0,5 cm
Then sort the onions by size. Individuals should be folded separately from 2-3 cm, from 1-2 cm and up to 1 cm. Seeds of different sizes are recommended to be planted separately and at certain times. First large, then medium, and only then the smallest onion. The best harvest can be harvested when planting the last two species. And large bulbs in most cases shoot arrows. Therefore, they are best used for greenery and seeds.
At the next stage of preparing the onion for planting, it is necessary to warm it up for 3-4 days. To do this, spread the paper near the heater and lay out the sets in one layer. In the absence of such an opportunity, it is necessary to soak it in warm water with a temperature of 50 ° C for five minutes, and then lower it into cold water for ten seconds. This will increase the resistance of onion seedlings to adverse weather conditions.
Then you should soak the sevka in Zircon. To do this, you need to place it in a mesh bag and immerse it completely in a nutrient solution for 8-10 hours. At the last stage of preparing the onion for planting, it should be disinfected. This will reduce the likelihood of damage to seedlings by fungal and bacterial diseases. To do this, you need to soak the sevka in potassium permanganate. After planting material, rinse with plain water and can be planted in the garden.
How to soak and how much to keep onion sets in potassium permanganate
When soaking onions in potassium permanganate, it is important to observe the required dosage, otherwise this procedure can destroy not only the pathogens living on its surface, but also the planting material itself.
There are several ways to carry out disinfectant treatment of sevka with potassium permanganate. And each of them provides for a certain dosage of the component, the duration of soaking.
Onion processing before planting with potassium permanganate can be carried out before winter and spring. But in the case of the first option, the seed after soaking must be dried at room temperature for a day.
After soaking in potassium permanganate, the sevok must be washed with plain water.
Weak solution
When using this method, you need to dissolve potassium permanganate in water at the rate of 3 g per 1 liter. Then carefully mix the resulting mixture until a homogeneous composition. Only then can the onion be soaked. The processing time is two hours.
concentrated solution
Soaking onion sets before planting in potassium permanganate can also be carried out in a more concentrated liquid. In this case, add 10 g of potassium permanganate to 1 liter of warm water and mix thoroughly. Soaking time 45 minutes. A longer stay of planting material in the working fluid can adversely affect its growth.
strong solution
It is also permissible to process onions in a strong solution of potassium permanganate. To do this, add 25 g of potassium permanganate to 1 liter of water. Soaking time is 15-20 minutes. Experienced gardeners recommend this treatment if the planting onion is suspected of being infected with powdery mildew.
Watering onions with potassium permanganate
To disinfect sevka, you can not only soak in potassium permanganate, but also water the soil before planting onions. Indeed, in the first case, only bacteria and fungi that live on the surface disappear, but they are also present in the soil, and they need to be disposed of.
To destroy pathogens in the soil, it is necessary to apply a solution of potassium permanganate immediately before planting onions. In this case, potassium permanganate will not only cleanse the soil of fungi and bacteria, but also saturate it with nutrients. After all, manganese is also necessary for the full development of seedlings, like other mineral compounds.
It is possible to irrigate the beds with a disinfectant solution only two weeks before planting the seedlings. During this time, it will be completely absorbed into the ground and stop the development of pathogenic microflora. When processing is carried out earlier or later than this period, efficiency is lost.
For watering the beds, you can use only a solution of potassium permanganate of low concentration at the rate of 10 g per 10 liters of water. At the same time, it is important that it be of a homogeneous consistency, and the crystals completely disappear, and not sink to the bottom.
It is necessary to water the soil with a solution from a watering can, and not in one stream. In this case, the liquid will be evenly distributed on the soil surface. The recommended consumption rate is 6-8 liters per 1 sq. m beds.
You can also spray potassium permanganate onion seedlings on a leaf throughout the entire growing season. To do this, dissolve 3 g of the component in 10 liters of water. At the same time, it is important to process the onion plantings carefully in order to apply the working fluid evenly.

Useful Tips
When using potassium permanganate for soaking sevka and disinfecting the soil in the garden, it is necessary to take into account some features of this procedure.
Useful tips from experienced gardeners:
- If the onion feathers are damaged, the soaking of the sevka should not be carried out. In this case, you can only spray it with a weak solution of potassium permanganate.
- When using a component for watering beds and treating seedlings during the growing season, it cannot be combined with nitrogen fertilizers, otherwise this will make the soil unsuitable for growing this crop.
- Soaking onions with potassium permanganate should be carried out immediately before planting, since in the future it is not subject to long-term storage.
- Potassium permanganate increases the acidity of the soil. And when it is introduced into the soil, this effect must be neutralized with wood ash at the rate of 200 g per 1 sq. m.
Conclusion
It is necessary to soak the onion in potassium permanganate before planting correctly, clearly maintaining the dosage of the component and the duration of the procedure. Careful preparation of the set significantly increases the chances of getting a generous vegetable harvest at the end of the season.
