Onions are considered an undemanding crop. Most novice gardeners mistakenly think that you can harvest a good vegetable harvest without much effort. This leads to a common problem - shooting, which does not allow getting strong heads at the end of the season. Experienced gardeners recommend paying special attention to seedbed preparation. To get a good harvest, you can soak the onions in potassium permanganate before planting. However, this procedure must be carried out correctly for it to be beneficial.
Potassium permanganate - an affordable antibacterial and antifungal agent
Why process onions before planting
Soaking the onion in potassium permanganate before planting is necessary to prevent it from being damaged by bacteria and fungi. When purchasing seed, there is usually no certainty that it was stored correctly in compliance with all the necessary requirements. And any violation of the sevka maintenance regime leads in the future to a loss of yield.
The lack of soaking at the stage of preparing the onion for planting leads to a low percentage of the yield of marketable fruits, since the bulk of the seedlings die during the growth process. At the same time, the head size is not more than average, and the likelihood of crop rotting during storage increases significantly.
Potassium permanganate, or potassium permanganate, is a potent antibacterial and antifungal agent. And pre-sowing soaking of onions in a solution of this substance allows you to destroy most types of pathogens living 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 seedlings 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 must 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 a high level of immunity;
- prevents the development of wintering pest larvae.
Disadvantages:
- inhibits the development of not only pathogenic, but also beneficial microflora;
- increases the acidity of the soil.
Soaking the seed in potassium permanganate, although it gives positive results, but the procedure should be carried out correctly. Exceeding the recommended dosage of this component will cause burns on the planting material. This leads to the fact that the seedlings cannot build up a powerful root system, which means that their development slows down.
Seeding preparation 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 basic steps that cannot be ignored.
Initially, the planting material should be sorted out, and all specimens that have signs of deterioration and mechanical damage should be discarded.
To speed up the germination of the seedlings, you can cut off the dry top by 0.2-0.5 cm
Then sort the onions by size. Specimens of 2-3 cm, 1-2 cm and up to 1 cm should be folded separately. It is recommended to plant sevoks of different sizes separately and at certain times. First large, then medium, and only then the smallest bow. The best harvest can be harvested when planting the last two species. Large bulbs tend to shoot arrows. Therefore, they are best used to obtain greens 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 paper near the heater and lay out the set 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 in cold water for ten seconds. This will increase the resistance of onion seedlings to adverse weather conditions.
Then the sevka should be soaked in Zircon. To do this, place it in a mesh bag and immerse it completely in the 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 infection of seedlings with fungal and bacterial diseases. To do this, you need to soak the seedlings in potassium permanganate. After the planting material, rinse with plain water and can be planted in a garden bed.
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 pathogens living on its surface, but also the planting material itself.
There are several ways to carry out disinfecting treatment of seedlings with potassium permanganate. And each of them provides a certain dosage of the component, the duration of soaking.
Processing onions before planting with potassium permanganate can be carried out before winter and spring. But in the case of the first option, the seedlings after soaking must be dried at room temperature for 24 hours.

Weak solution
When using this method, you need to dissolve potassium permanganate in water at the rate of 3 g per 1 liter. Then mix the resulting mixture thoroughly until smooth. Only then can the onions be soaked. The processing time is two hours.
Concentrated solution
Soaking the 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. Duration of soaking 45 minutes. A longer stay of the planting material in the working fluid can negatively affect its growth.
Strong solution
It is permissible to process onions in a strong solution of potassium permanganate. To do this, add 25 g of potassium permanganate per 1 liter of water. Duration of soaking 15-20 minutes. Experienced gardeners recommend that such processing be carried out if there is a suspicion of contamination of the planting onion with powdery mildew.
Watering onions with potassium permanganate
To disinfect the seedlings, 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 you need to get rid of them.
To destroy pathogens in the soil, it is necessary to add a solution of potassium permanganate immediately before planting onions. In this case, potassium permanganate will not only cleanse the soil from fungi and bacteria, but also saturate it with nutrients.After all, manganese is also necessary for the full development of seedlings, like other mineral compositions.
It is possible to water the beds with a disinfecting solution only two weeks before planting the seedlings. During this time, it is completely absorbed into the ground and stops the development of pathogenic microflora. When processing is carried out earlier or later than this period, the effectiveness 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. In this case, it is important that it is of a uniform 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 onion seedlings with potassium permanganate on the leaf throughout the growing season. To do this, you need to 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 to soak the seedlings and disinfect the soil in the garden, it is necessary to take into account some of the features of this procedure.
Useful tips from experienced gardeners:
- If the onion feathers are damaged, do not soak the seedlings. In this case, you can only spray it with a weak solution of potassium permanganate.
- When using a component for watering the garden and processing seedlings during the growing season, it cannot be combined with nitrogen fertilizers, otherwise it 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 soil acidity. And when it is introduced into the soil, you need to neutralize this effect with wood ash at the rate of 200 g per 1 sq. m.
Conclusion
It is necessary to soak the onions in potassium permanganate before planting correctly, clearly maintaining the dosage of the component and the duration of the procedure. Careful preparation of the seedlings greatly increases the chances of a generous vegetable harvest at the end of the season.
