How to process onions before planting

Growing onions at the site seems, at first glance, a very simple task. However, if you want to get large and dense heads, and not just green arrows, you will have to work hard. Basically, it concerns the proper preplant preparation and meeting the deadlines for planting sevka.

Preparation of onions for planting

First you need to carefully select the bulbs for planting, sifting out soft, dried and too small. Then, to accelerate germination, the husks must be cut, dried in a warm and dry place and heated for 2-3 weeks at + 20ºС. Closer to planting, it must be heated well at a temperature of + 35-40ºС for 10 hours.

An important step in the preparation of onion is its disinfection. This should be done immediately before landing in the ground. The simplest and most effective method that our grandmothers used was the treatment of onions before planting with salt and potassium permanganate.

At the first stage, before planting, the onion is treated with salt. To do this, immerse the seed for 2-3 hours in saline solution, prepared at the rate of 2 tablespoons of salt (stone or table) per two liters of water.

Treatment of the onion with saline solution will give the plant a rapid development and will ensure its protection against aggressive environmental influences. Also salt disinfects onions from nematodes.

The second stage of preparation is the treatment of onion seed in the spring before planting with potassium permanganate. You need to dilute 35 g of potassium permanganate in 10 liters of water and immerse the onion in this solution for a couple of hours. This simple method is the most effective against any diseases. And although today there are many new drugs for processing, potassium permanganate has been and remains the most sought-after, since it is very effective with its low cost.

Another option preseeding preparation of onions:

  • Before planting, onions need to fall asleep in a bucket and pour hot water (65-70ºС) for 2 minutes, then put it down for a minute in cold water,
  • then soak the onions in the nutrient solution (you can use 1 tablespoon of complex fertilizer per bucket of water) for 8-10 hours,
  • drain the solution and drop the onion into the copper sulphate solution (1 teaspoon for a 10-tilitre bucket of water) for 5-7 minutes, without washing, for 5-7 minutes,
  • rinse the bulbs and you can start planting.

Preparing the soil for planting onions

If you want to grow a good harvest of onions, it is not enough just to treat the seeds, it is also important to choose the right place for planting and prepare the soil. And you need to start preparing the beds in the fall.

Onion loves good light and grows best in sunny areas. He also moisture-loving, while not tolerate waterlogging. Because groundwater or should not be at all, or they should lie at a considerable depth.

Such crops as peas, potatoes, tomatoes, or cabbage are most suitable as precursors of onions. You can also plant carrots close to an onion bed so that its phytoncides can chase away an onion fly.

From autumn, the selected area needs to be dug up, to bring rotten manure and peat. If the soil is acidic, you need to liming it to create optimal conditions for onions.

It is not desirable to apply fertilizer in the spring before planting, because from this the onion will put a lot of feathers, and the bulbs will not be large enough. You just need to loosen the bed, destroying the surface crust, and you can proceed to the landing of the prepared onion.

It is necessary to plant the bulbs at a distance of 8-10 cm. It is necessary to cover the ground so that the layer above the shoulders of the onion should be no more than 2-2.5 cm. Further care is loosening, weeding, watering.

Why spend processing onions when planting in the spring

Most often, gardeners do not consider it necessary to treat onions before planting in spring. The bulbs themselves germinate well. Sometimes still during storage. Often the onions are infected with pathogenic bacteria. When the harvest is rotting from the root collar, it is too late to fight for its preservation. It was necessary to begin with the prevention of rot before spring planting.

Processing bulbs before planting in the ground is carried out not only to prevent disease, but also to reduce marksmanship. Proper processing before planting in the ground also does not allow the onion fly to lay eggs and deprive the grower of the crop.

Processing onions before planting in the spring against rifle

Flower buds in the bulbs are laid in the winter with improper storage. Therefore, the first step is to create the right conditions for storing onions. Flower buds are laid when storing large and medium onion sets at too low temperatures. These onion fractions should be stored at a temperature of 17-18 ° C. A sevok with a diameter of less than 1 cm does not give arrows, since it does not have an adequate supply of nutrients for budding. Such onions can be stored at a temperature of from 0 to 17 ° C. Before planting sevok heated.

Warming up

There are 2 ways to warm the seed before planting:

Both paths involve some risk of overheating of planting material and yield loss. When warming up, you need to strictly follow the time.

The "water" method is used when it is necessary to prepare the bow for planting for 1 day. Bulbs are thrown into water with a temperature of 40-45 ° C for 10-13 minutes. After they are removed and allowed to cool for 2-3 hours. Now the bulbs can be planted.

Another variant of warming up with water takes a little longer, but allows you to simultaneously supply the seed material with nutrients. In water with a temperature of up to 50 ° C bulbs stand 10 minutes. After the onions are placed in cold water with fertilizer diluted in it. The procedure will take about 6 hours.

Warming up on the battery involves a multi-day preparation. A thick fabric is placed on the battery and the onions are heated at a temperature of 30-35 ° C. It takes 2 weeks to warm up a large set-up. Small warm for 9 days.

Pest Control

The main problem for a growing onion is its “personal” pest. The onion fly lays the eggs on the plants, and the larvae eat away the whole core.

This misfortune can be avoided if before planting to carry out the processing of onions from onion flies. Bulbs damage not only fly. They can exterminate the crop and other garden pests: wireworm or medvedka. The easiest way to scare away all insects at once, soaking sevok before planting in diluted birch tar.

For accelerated growth

Onion seeds (black onion) to accelerate germination can be treated with the same preparations that are used for any other seeds. It can be manufactured by industrial fertilizer, "industrial" organic from humates or humite. Sometimes used and traditional methods of manufacturing fertilizers.

How to handle onions before planting

When treating onion seeds before planting in the spring, they perform the same operations as with all other seeds:

  • disinfection,
  • soaking in liquid fertilizers.

Soak the seeds for a period of 8-12 hours. You need to make sure that there is no oxygen starvation. With a simple soaking in water, the seeds periodically need to remove the seeds from the liquid. But it is possible and not to take out, if in parallel with soaking fertilizer in the solution of fertilizers, to carry out bubbling.

When planting bulbs preparation begins with the purchase of Sevka in the store. Planting material is sorted and discarded rotten and soft onions. Fully dried onions are also thrown away.

Enumerated onions are dried on the battery, at the same time warming up to prevent marksman. Warming up is carried out in 2 stages: 2-3 weeks at a temperature above 20 ° С, then 10 hours at a temperature of 35-40 ° С. Such a temperature will not kill the pathogenic microorganisms, so after warming the seed will need to be soaked in disinfectants.

As for further actions, gardeners have two opinions. Some people think that before soaking the onion, which has not yet begun to germinate, must be “cut” and that the exit for the green arrows should be made easier. Others are of the opinion that cutting only opens the door to infection. The husk, soaked in liquid, is not able to create a barrier for new feathers. For himself, everyone decides for himself which of the theories is closer to him.

Soaking onion is carried out in solutions:

All of these tools are used to kill pathogens. Not everyone uses them. Most often they use a complex of 2 substances, experimentally choosing those that they like more.

In addition, it can be treated with pest repellents or fertilizer solution.

Processing onions before planting salt and potassium permanganate

This is the most common combination of operations in preparing the set-up for landing. First, before planting, the onion is treated with salt:

  • in hot (40-50 ° C) water salt is added at the rate of 1 tbsp. l per liter of water
  • Sevok soaked in brine for 6-8 hours,
  • taken out and allowed to drain.

Salt treatment helps protect future crops from nematodes and other environmental influences.

After the salt water glass, the onion is dipped in potassium permanganate. The solution is made either by eye: a strong dark composition, or at the rate of 40 g of potassium permanganate per 10 liters of water. In potassium permanganate, onions are kept for 30 minutes. Processing onions with potassium permanganate before planting helps protect the plant from fungal and viral diseases.

After soaking in potassium permanganate, the onions are removed from the solution and washed with warm water. After that, the seed can be planted in the ground.

Processing onions before planting soda

Some gardeners believe that the treatment of soda helps from the arrow. The theory requires confirmation, but soda is a disinfectant that can be used instead of salt and potassium permanganate.

For the preparation of soda solution take 1.5 tsp. on 1 l of water. Sevok soaked for 2-3 hours. Soaking soda protects planting material from rot and other infectious diseases.

It does not penetrate deep into onions. The action of soda is similar to industrial preparations such as Fitosporin, Maxim and others. But unlike industrial products, soda is a very cheap and affordable product.

Processing onions before planting blue vitriol

When processing onions with copper sulphate, preparation of seedlings before planting also takes place in 2 stages:

  • maceration in complex fertilizer,
  • soaking in a solution of copper sulfate.

At the first stage, any fertilizer is diluted and for 10 hours a sevok is placed in a liquid. After taken out and immediately immersed in a bluestone for 10 minutes. After that, the bulbs can be planted.

Preparation of vitriol solution: 1 tsp. 10 liters of water. Copper sulfate prevents fungal diseases, fertilizer solution stimulates growth and provides the bulb with additional nutrients.

The second option: the first treatment with saline solution, the second - with copper sulphate. The recipes for preparing the solution are the same as described above: salt - 1 tbsp. per liter, vitriol - 1 tsp. on 10 l. But in this case, the first solution is not with fertilizer, but with salt.

Processing onions before planting tar

Processing of tar before planting is carried out to scare away pests. Insects do not like the smell of tar. Prior to this, soak in growth stimulants and disinfectant formulations.

Ingredients: 1 tbsp. birch tar in 1 liter of water at room temperature.

Sevok soaked for 2-4 hours, stirring occasionally, so that the planting material is uniformly soaked with tar.

Biological Treatment

Biological preparations can be of 2 types: growth accelerators and fungicides. Humic acids / humates, which are produced industrially from peat, sapropel or bottom coal, can be attributed to biological growth accelerators.

Sapropel - centuries-old deposits at the bottom of a freshwater reservoir. Contains a large amount of organic matter.

Purchased concentrate is diluted according to the instructions and soaked sevok in it. Onions respond well to the use of humates.

Processing onions with gumite before planting

Humite is an analogue of humates, but obtained by special technology from biohumus. Biohumus, in turn, is a renewable source of fertilizer, as it is produced by earthworms. Dilution of the concentrate and processing before planting also carried out according to the instructions on the package.

Processing onions before planting phytosporin

Fitosporin - fungicide on a biological basis. It contains the spores of bacteria that can fight many diseases:

  • powdery mildew,
  • white spot,
  • root rot,
  • fomozom
  • black rot
  • snow mold
  • fruit rot,
  • bacteriosis
  • phytophtora,
  • peronosporosis,
  • tracheomycosis,
  • brown rust.

The treatment is carried out with the second number before planting the bulbs in the ground.

Phytosporin is diluted in the dosage indicated on the label, and the onions are kept in it for 8 minutes.

Processing onions before planting

The first and very important step is the treatment of planting material before planting, first it is necessary to sort out The selection should be done as follows:

  • Very soft and bad small onions should be thrown away immediately, because they will not give a good harvest. And also need to get rid of completely dried seeds.
  • If the bulb has no feathers, it is recommended to “cut” it. For this you need to carefully cut off the husk, this procedure to accelerate the germination of the plant.
  • Then you need to dry the selected seeds in a dry and warm place.
  • after that you need to warm the planting material. This is done in several stages. First, the seeds are aged at a temperature of not less than twenty degrees, this is done for about three weeks, and then for ten hours they warm up at thirty-five or forty degrees. For the time you need to carefully look at the onions not to overdo it, otherwise it will give a bad harvest.

And you can also recommend a different approach, which will be an alternative to such a long warm-up. This method involves seeding soaks in water with a temperature of up to fifty degrees for ten minutes, then you need to buy them in a nutrient mixture of fertilizers and cold water. This procedure takes about six hours, and the effect is the same.

How to process onion sets before planting

Seeding in spring - This is a mandatory preparatory stage. Processing is performed before planting and consists of the following procedures:

  • Onion seeds should be immersed in a weak (two liters of water two tablespoons of salt) solution. This treatment will help ensure the fastest possible development of the plant, as well as protect it from all bad environmental influences, and disinfect the bulb from nematodes. You can use both sea salt and ordinary stone, the effect will be the same. It is necessary to immerse the seeds for three hours.
  • Disinfection with potassium permanganate. This tool remains the most popular and very inexpensive, even though many other effective new substances have appeared. Such processing before planting is as follows: thirty-five grams of potassium permanganate must be diluted in ten liters of water, after which good seeds are immersed in the solution made. In order to provide protection from pests and diseases, 2 hours will be enough.

Instead of potassium permanganate, you can use Fitosporin or copper sulfate, the dosage should be the same.

Soil and its preparation for planting onions

Only properly processed plant seeds can produce an excellent harvest. But for this you need to choose the right place for their landing and prepare the ground for this. This process should begin in the fall. Do not forget that onion seeds love places where there is a lot of sun. As well as seeds love moisture, but a large amount of it will lead to their death. For this reason, it is necessary to choose a place that is well lit by the sun's rays, and where there is no groundwater.

In the fall, the site for sowing, you need to carefully dig and fertilize, suitable for fertilizer mixture of manure and peat. Optimal conditions for growing onions on acid soils to perform its liming.

If you do not want to grow onions only on the feather, then you do not need to apply fertilizer before planting. In addition, this treatment can stimulate the growth of weeds, and you will be forced all summer to weed the beds to get rid of them. In the spring there will be little work, you will need to loosen the soil a little to remove a hard crust and you can start planting onions.

In areas where crops such as tomatoes, potatoes, peas and cabbage grew before planting onions, the plant will grow very well. Additional protection for onions can be a carrot, which is planted next to it. Her phytoncides they will drive away the onion fly and allow them to harvest a very good crop.

Fight against diseases and pests

Important by stage to obtain a good harvest after planting is to protect the onions from diseases and pests. The growth of onion sets, very often prevent various diseases and pests, they damage feathers and make the bulb rotten and soft. The damaged crop will not be saved, for this reason, before planting, onions must be protected from pests. The most famous diseases of onion are:

  1. Onion fly.
  2. Мучнистая ложная роса.

Если растение повреждено луковой мухой, то у него будут сохнуть и вянуть перья, а центральный лист при этом, будет очень легко отламываться, так как он начинает гнить с основания. Если вы внимательно присмотритесь к растению, то сможете увидеть маленькие личинки луковой мухи.

In order to prevent onion flies, seeds should be treated with fentiuram or TMTD solution. If the onion fly struck the shoots themselves, it will help you wood ash or crushed charcoal, which need to sprinkle the soil around the seedlings. Nexion (0.1%) diluted in 0.5 liters of solution can be used for young plants.

A sign of downy mildew there are white spots on the feathers of onions, they begin to increase with time, and a gray patina appears. The cause of this disease is high humidity. To combat this disease will help:

  • Eighty percent kuprozan.
  • Ditan M-45.
  • Bordovskaya one-percent mixture.

To protect the plant from diseases you need:

  • Early planting bulbs.
  • Time to remove weeds.
  • Periodically water and feed the plant.
  • Collect and remove damaged crops.

The purpose of preplant processing

If you use seed purchased on the side when planting in the spring, it is necessary to process it. You can not be 100% confident in the quality of the sevok purchased on the market. What exactly give such events? Processing allows you to:

  • increase the germination rate
  • accelerate the growth of bulbs and feathers
  • prevent rotting and mildew,
  • protect against pests,
  • prevent early boom
  • increase the amount of the crop.

Types of treatments

What is the way and how to handle onions before planting in the spring? There are different ways. You can use several of them at once.

  • First onions sorted.
  • After that, you can warm it in a dry heat.
  • A positive result will give soaking onions in warm water or salt solution.
  • Soaking in an antiseptic (potassium permanganate and other means) is necessary.
  • Before planting, they harden the seeds and process them with a growth stimulator.

Land for planting onions also needs to be shed with the same solutions that were used to process the seed. For the beds you need to choose the right place.

What are the bulbs sorted and heated for?

Processing onions before planting start by sorting it. Seeds need to sort and remove the bulbs that have rotted or began to turn black, and disassemble the rest by size. Large, medium and small bulbs are planted separately, which facilitates care.

The onions are heated so that it gives a lush feather and it happens as quickly as possible. The growth of the onion arrow is delayed. At the same time, the procedure helps to get rid of at least partially the pathogenic microflora. For heating, use short-term baths in hot or warm water, which alternate with cold. The higher the temperature (the maximum allowable is 70 ° C), the less time the soaking process should take.

Some do not use water for this.and a microwave. Onions are placed inside on a platter and switch on the average power mode for 2 minutes. You can warm up sevok and raising the temperature in the room. At 40 ° C it should be 7-8 hours, at 30 ° C - 10-12 days. For small bulbs, the time of heat exposure can be slightly reduced, and for large ones, on the contrary, it can be increased.

Treatment against diseases and pests

Before soaking, cut the tips of the bulbs with scissors so that the disinfecting effect is maximized. What is soaked onions before planting? Most often for processing use a solution of potassium permanganate, salt, copper sulphate and saltpeter.

When preparing a solution of potassium permanganate is used proportions 1gr. crystals per liter of water. Observing this dosage, you can prepare any volume of the composition with potassium permanganate, depending on the needs. For disinfection, it is enough to process the bulbs for 20-30 minutes. To dry them after this is no longer necessary, you can immediately plant.

A saturated solution of table salt (3 tablespoons per 5 liters of water) will protect the plants from damage by the stem nematode. Salt is dissolved in warm water and the bulbs are soaked in it for 10-15 minutes. Land before planting, too, shed saline, but use half the concentration.

If vegetables in your area are often damaged by fungus, treat the bulbs for prevention before planting. solution "Fitosporina". At 10 liters of water take 35 grams. powder and mix thoroughly. In this composition, the bulbs are soaked to half an hour. The same solution spills the soil for planting.

Copper sulfate prevents mildew and rotting. At 1 liter of water consumed 3 grams. crystals of matter. Soak the onion in the solution from 20 minutes to half an hour. The treatment time can be shortened by using water heated to 60 ° C. Do not forget to dip the bulbs in cold water. After treatment with vitriol, the landing can be carried out in 5 hours.

Saltpeter to prepare a solution diluted in the amount of 2-3 grams. on a bucket of warm water. Soaking in this solution has a double effect: it protects against diseases and stimulates growth. Hold the onion in it for 20-30 minutes, and then use this solution to fertilize the soil.

Acceleration of growth

So that the onions grow quickly, you can take additional measures. Fertilizers and special growth stimulants can affect it in this direction.

Instead of industrial fertilizers, you can take a solution of ash, which will saturate the bulbs with potassium and at the same time act as a prophylactic against diseases. After all, ash is a powerful natural antiseptic and prevents the development of rot. The working solution is prepared from 5 liters of water and 250 gr. ash. It is enough to hold the bulbs in it for about 10 minutes, then they are dried for 2-3 hours in air.

A famous growth stimulant is drug "Epin-Extra". One capsule per five-liter bucket of water with a temperature of 45 ° -50 ° is enough. Soaking time is 15 minutes. The same purpose will serve the drugs "Biostim" and "Silk". Their required concentration is indicated on the packaging. Stimulant growth is treated only seed, which is planted in the spring. If the bow is intended for planting in the winter, such treatments are not carried out.

Seed treatment

In the middle and northern latitudes, onions are planted with small onion bulbs last year to get full round bulbs. To the south, by planting seeds, you can get a fluffy feather first in one season, and then a large mature turnip. Do I need to process the seed before sowing? Undoubtedly, to increase their germination.

For starters, put them in a bowl and pour a strong solution of salt (3 tablespoons per 1 cup of water). After a few minutes, the plate is shaken. Part of the seeds will remain at the bottom, and some will float to the surface. Emerged seeds can also be planted, but the shoots of them will appear later.

After sorting the seeds in this way, they are washed separately and then dried. Before landing you can repeat all the same procedures, as with small bulbs: soak in saltpeter and potassium permanganate, copper sulphate solution. The secret of uniform sowing is mixing onion seeds with river sand or sawdust just before planting.

Preparation and soaking onions in potassium permanganate

The correct name for a substance that is commonly referred to as potassium permanganate is potassium permanganate, or potassium permanganate. It is very effective in combating bacteria and viruses, and is easy to obtain at the pharmacy, although soaking seeds in potassium permanganate does not guarantee that all harmful microorganisms will be destroyed. Those pathogens that manage to penetrate the seed, can survive after such treatment. But the risk of a disease is still reduced, so this treatment is very important.

The main rule of soaking seeds in a solution of potassium permanganate

But here one important rule should be remembered: when preparing the solution, it is necessary to observe the correct dosage of the active substance, even if the seed material is soaked with brine. What to say about potassium permanganate! The fact is that an excess of the active substance can harm not only the microbes, but also the seeds themselves, and then they will definitely not be able to ascend. And so that the effect of the solution is not in vain, it is worthwhile to soak the seed set immediately before planting. Then the bow is much more likely to climb.

Methods for soaking onions in potassium permanganate

There are three ways of soaking, and it is difficult to say which one is better to use. All of them differ in the concentration of the solution and the time of soaking the bulbs.

In the first method, a more concentrated solution is used, and the seed treatment time is reduced. Here the concentration of potassium permanganate is 1%. That is, per 1 liter of water accounts for 10 g of potassium permanganate. If it is not possible to weigh the powder using scales, then it can be measured using a teaspoon. 1 tsp without top holds 6 g of potassium permanganate. The powder dissolves in tepid water, and the bulbs are soaked in it for 45 minutes.

The second option involves the use of a weaker solution, in which only 3.5 g of the substance is dissolved in 1 l of water. In this case, it will take longer to place the onion sets in potassium permanganate before planting. In a similar weaker solution, the seed material is aged for 2 hours. Although the solution is inferior in impact, it is less likely to harm the seeds. But many gardeners when planting prefer to use the first method, with a stronger mixture. According to their reviews, it saves all germs and all viruses more reliably.

But the third method is used in relation to onions only when there is a suspicion that it is infected with powdery mildew spores or other dangerous diseases. Such a solution is very strong, but can also harm seed material. It is used only in the event that without him the seam does not rise. In a similar solution, 20–25 g of potassium permanganate fall into 1 liter of warm water. Warm water is thoroughly mixed with the added potassium permanganate salt. The resulting mixture is obtained dark beet color. In her onions are kept no more than 20 minutes.

Manganese processing onion beds

If you dunk the bulbs with potassium permanganate, you can get rid of most of the viruses, fungi and bacteria that have settled in them. But it is necessary not only to soak the seed material, but also to treat the soil with the help of solutions of the same type. And if it is not worth treating the soil with salt, it is recommended to make potassium permanganate. Such a solution not only allows you to get rid of various fungi and viruses that have settled in the soil, it also supplies it with manganese, which is necessary for the normal development of plants. But in order for watering such a solution to be beneficial, it must be carried out according to certain rules:

  • In the spring, only a very weak solution of potassium permanganate is used to fertilize and disinfect the soil. To do this, in a 10-liter bucket of water dissolves 5 g of potassium permanganate. Water should be warm, and the crystals of potassium permanganate should be completely dissolved.
  • You need to water with the help of a watering can, evenly distributing moisture over the garden bed. Moreover, it is necessary to process the top layer of soil in which the onion will be planted. According to many gardeners, one watering can lasts for 6-8 square meters. m beds.
  • Watering is carried out for 2 weeks before planting, in order to feed managed to soak into the soil and disinfect it. If you pour the earth in the spring sooner or later, the effect will be incomplete.

Features of the impact of potassium permanganate on the soil

Regardless of whether the area has been treated, it is recommended that seed be soaked in a solution of potassium permanganate in the spring. Onion processing with potassium permanganate before planting is also done in order to get rid of harmful fungi and microbes. If soaking sevok and treat the soil with a similar solution, then diseases will be more difficult to hit the beds.

Processing with potassium permanganate should be combined with fertilizing with nutrient solutions and using substances such as copper sulfate. The combined effect of vitriol and potassium permanganate on the soil almost leaves no chance to pathogens of many diseases.

But it should be remembered that potassium permanganate oxidizes the soil, so it is used to make alkaline soils neutral. It is possible to treat the soil with manganese salt, and then neutralize its effect with the help of liming. It is not recommended to combine the solution of potassium permanganate with nitrogen-containing fertilizers, since in this case the acidity of the soil increases by an order of magnitude. Sevok, planted in a similar soil, will not be able to germinate normally. His bulbs will begin to rot and deteriorate almost from the first day of planting. But here you can neutralize the negative effects with ordinary ash or cement dust.

Spraying onion beds with potassium permanganate

Potassium permanganate is cheap, but at the same time it is a measure of an effective fungicide that allows you to get rid of a number of harmful fungi. And it is not necessary to soak young sevok only in its solution. You can still spray water with manganese salt. Especially well this remedy helps against peronosporoza, or, as it is also called, downy mildew. This fungus badly damages the bulbs and ruins the onion feathers, and soaking them in the solution, of course, will not work, so you have to resort to spraying with potassium permanganate solution.

This solution is made with an even lower concentration than for watering the soil. 3 g of potassium permanganate is taken and dissolved in a 10 liter water bucket. Then tepid water is thoroughly mixed with the salt of potassium permanganate, and onion sprinkled with fungi or diseases is sprayed with it. And it is necessary to spray everything very carefully: the leaves should be completely covered with moisture, the soil should also become wet. Spraying is done 3 times for 1-1.5 weeks.

Here is what those who have tried this method in practice say about the results:

“Some site owners are beginning to argue that treatment with potassium permanganate is ineffective. But if you soak the seeds in a solution of potassium permanganate, then diseases have very few chances. And spraying the bed with a solution of the same potassium permanganate is very effective against powdery mildew. Severe and neglected infections will not be able to stop such treatment, but it is quite capable of curing the disease at an early stage. And in principle, there is no better prevention than spraying plants and soil with potassium permanganate. ”

Conclusion

Processing onions before planting with potassium permanganate is a long and painstaking process. But if they try to neglect, then it will not be possible to get a harvest. That is why experienced gardeners are engaged in such preparation in advance. And this preparation is always bearing fruit, in the literal and figurative sense.
