Onions: how and what to process before planting


Garden plants

Hello, dear friends - summer residents and gardeners!
I live in the Dnieper region, which is located in central Ukraine, and in mid-April it is time for us to plant onions in open ground. Before planting, I always treat the seed for diseases and pests using different means.

I have already told you about some of them, but today I will share another method that has a triple effect:

  • protects onions from common diseases and pests, especially from onion flies;
  • feeds the bulbs with iron, preventing the development of chlorosis;
  • facilitates the absorption of nitrogen from the soil by the roots.

Disinfection of sevka

Ferrous sulfate solution

Before processing, I went through the seedlings, threw away all the empty, damaged and sprouted bulbs, and put the ones suitable for sowing in a five-liter eggplant with a cut off top, because this manipulation requires a non-metallic and sufficiently deep container. For processing, I will use ferrous sulfate (Fig. 1.1).

This drug is much milder than, for example, copper sulfate. It destroys the causative agents of fungal diseases and serves as a glandular feeding for the bulbs, stimulating their development.

To prepare a disinfecting solution, I pour two tablespoons of ferrous sulfate into a liter jar (Fig. 1.2), fill them with warm water (50 ⁰C) and stir until the crystals are completely dissolved (Fig. 1.3). Then I fill the sevok with this solution (Fig. 1.4).

To process 1 kg of planting material, 1 liter of solution is required: the bulbs must be completely immersed in the composition. I cover the eggplant with the set with a plastic bag (Fig. 1.6) because of the not very pleasant smell of iron sulfate.

Processing should last at least two hours. During this time, you will need to mix the onions at least once. After the specified period, the solution must be drained, and the onion must be rinsed well under running water. Sevok darkens slightly from the solution, but such is the effect of ferrous sulfate.

Birch tar

The next stage of processing is carried out to protect the set from onion flies and other pests. The active drug is birch tar, which can be bought at any pharmacy, and recently it has been sold in gardening stores. With its specific smell, which persists for quite a long time, birch tar repels insect pests from cultivated plants.

Since tar does not dissolve in water, I will make an emulsion solution out of it: in a liter jar I thoroughly mix 2 tablespoons of liquid dishwashing detergent (Fig. 2.1) with one incomplete tablespoon of tar (Fig. 2.2) and, continuing to stir, gradually add water at room temperature to get 1 liter of the drug (Fig. 2.3). Instead of dish detergent, you can use animal shampoo, liquid soap, or grated laundry soap.

I pour the sevok with the resulting soap-tar solution (Fig. 2.4), cover the eggplant with a bag (Fig. 2.5) (the smell of tar can hardly be considered a scent) and leave it for another 2 hours so that all the onion scales are well saturated with tar. After two hours, I drain the solution, but it is no longer necessary to rinse the sevok with water.

Sowing seedlings in the garden

Preparing a bed for onions

I will plant the processed onions on my new bed-box (Fig. 3.1), the length of which is 6 m and the width is 1.5 m. Since I have mostly loam on my site, to loosen the soil I brought 30 kg to the garden bed for digging sand, adding a few handfuls of professional fertilizer such as Nitroammofoski and 4 liter cans of wood ash, so I will not add anything to the furrows when planting onions.

For convenience, I applied a marker every 10 cm along the long sides of the bed box (Fig. 3.2), and now it became much more convenient for me to make grooves or plant seedlings at the same distance from each other. For the onion, I made grooves at a distance of 20 cm: first, using a building level, I outlined the lines, and then I dug grooves 8-10 cm deep along them.

I shed each furrow thoroughly with water (Figure 3.3) so that the onion would take root faster, and as soon as the water was absorbed, I planted the seed in 10 cm increments (Figure 3.4), covered the furrows with earth and leveled the surface of the bed with the back of the rake. Now I just have to wait for the shoots.

This is how I disinfected my onion set before planting from diseases and pests and additionally fed it with iron. Try my method too, and I wish you all good luck, good mood and rich harvests.

Why is it necessary to process onions with potassium permanganate

While seasoned landowners reap an excellent harvest, budding growers face the challenge of shooting onions and cannot grow strong heads. Why is this happening? Perhaps the secret lies in the correct preparation of the planting material? And this is true, because not everyone knows that the treatment of onions with potassium permanganate before planting helps to protect the sown product from death. Want to start getting a great harvest by saying a tough "no" to fungal diseases? Then rather read the review, because it reveals the secrets known only to a select few farming masters.

Processing onions with potassium permanganate before planting


Preparatory operations before planting onions

Before processing onion sets before planting in spring, you should have information on possible onion diseases. In this case, one must not forget what kind of disease is common in the personal plot. If there is no such data, then you can go the other way. To do this, the set is determined in hot water, at a temperature of + 45-50 ° C, for up to 10-15 minutes, after which the bulbs are immediately placed in cold water for the same time. After that, the bulbs are placed in a solution of complex mineral fertilizers for 3-4 hours. Only then are the bulbs planted in open ground.

Spring processing of onion sets before planting from diseases and pests involves disinfection to reduce the risk of disease. Potassium permanganate is widely used for disinfection, or rather a solution of potassium permanganate. In order to get a working mixture, you will need to dilute 1 g of potassium permanganate in 1 liter of water. The onions are dipped in this mixture for 20-25 minutes. For such events, copper sulfate is also suitable, in a ratio of 3 grams per 1 liter of water.


In both autumn and spring, it is recommended to treat onions with tar before planting, which will protect the plants from onion flies. Birch tar bought in a pharmacy is diluted in water (1 tbsp. L. In 1 liter of water) and placed in it for three hours.

After soaking in any solution, dry the bulbs before planting.

Etching in potassium permanganate

To protect against diseases, onion sets are soaked for two hours in a rich purple solution of potassium permanganate before planting. Such a solution is prepared from 5 liters of water and 1.5 g of crystals. After processing, the planting material is dried.

Soaking in baking soda

To prepare a solution of baking soda for processing onions, you will need 0.5 liters of warm water and 0.5 tsp. soda. In a soda solution, the seedlings are kept for two hours, after which they are dried and planted in the ground.

Fitosporin treatment

Compared with potassium permanganate and soda, Fitosporin is a more effective remedy that can protect plants from many diseases. Therefore, today most gardeners prefer soaking onions before planting in Fitosporin.

In specialized stores, the drug is sold in the form of a powder or paste. It should be diluted and used strictly according to the instructions attached to Fitosporin. It is very important to know that the solution is being prepared at least 2 hours before use. They can not only process the planting material, but also water the soil before planting.


Why process onions

Many gardeners plant onions in the ground without any processing, and they get a good harvest. The question arises, why waste effort, time, money, since he will grow up anyway? If the plot is large, the crop rotation is observed, the harvest is satisfactory, and you have grown the sowing from seeds yourself and are sure of its quality, pre-planting preparation can be omitted.

But pre-processed onions will give a greater yield, spending time preparing them in the spring, in the summer you will less likely to break out arrows, fight pests and diseases. We cannot predict the weather conditions, even an ideal planting plant can get sick in rainy weather, and pests will move from neighboring beds.

If you are not sure about the planting material, there is no way to observe the crop rotation, but you want to get a good harvest, it is imperative to treat the onions before planting for diseases.

How to eliminate yellowing of onion feathers due to lack of nitrogen?

This is a fairly common reason leading to lodging and yellowing of the feather; it can be eliminated by fertilizing the bed with nitrogen-containing preparations:

  • Urea
  • Ammonium nitrate.

You should not get too carried away with the introduction of nitrates, so as not to cause an active increase in green mass and not to slow down the formation of bulbs. To process the onion with organic matter when the feather turns yellow, you can prepare your own liquid fertilizer containing not only nitrogen, but also other nutrients important for plants:

  1. Rainwater is poured into a container (basin, bucket, barrel, etc.), exposed to the sun.
  2. Green grass is laid (preferably without seeds), hay, food waste of plant origin.
  3. Sugar, old jam is added to speed up the fermentation process.
  4. The mass is periodically stirred until it ripens (the appearance of a characteristic odor).

A liter of the resulting mixture is added to a bucket of water, the beds are watered on the moistened earth with an interval of 7-10 days.
