To grow a good crop of vegetables, every gardener should know that for This requires high-quality seedlings, weeding beds, timely watering and the destruction of pests. One of the main components of plant care is planting fertilizer. For fertilizer, both organic solutions and chemical preparations are used. Organic fertilizers include mullein, bird droppings and extracts from rotted weeds.But we will look at a substance like boric acid for tomatoes and find out what it is and how to use it.

Boric acid for processing tomatoes

Description of the preparation

This is a chemical that can be found in nature. It is found in mineral springs, hot geysers and the sassolin mineral. Isolated chemically, with a mixture of sodium tetrabonate (borax) and hydrochloric acid, it is odorless. Powder of white or transparent color, upon closer examination, consists of layered flakes. Orthoboric acid is relatively poorly soluble, relative to others, but it is possible to get a suspension of it in hot water.

Caution and personal hygiene are necessary when working with this drug. If ingested orally, in the human body, it can lead to death.Fatal for an adult, is considered a dose of about 15 grams, and for children 4 grams is enough to kill a child. So, when applying it to fertilize plants, you need to be extremely careful.

How to determine the lack of boron in the soil

The most correct, to determine the presence of various substances in the soil, naturally is her chemical analysis. But in a private household, this can be determined by the state of the plants.

  1. If it is noticed that with a green top, the leaves of tomatoes have yellowness.
  2. It often happens that the leaves become stained and curled.
  3. The stalk itself can break, because it becomes fragile.
  4. Flowers of vegetable crops are few in number and do not give an ovary.
  5. The set fruits may, partially or completely, crumble .
  6. The bush becomes ugly curved and there are very few leaves on it.

These signs are sufficient to understand that the soil does not Vatan boron, as can be seen in the video. If everything is left to chance, then the growth point will die, and eventually the whole plant will die.

Advantages of the chemical preparation

Tomato seeds are often treated with a mixture of boric acid with potassium permanganate, in order for the tiny plant to become stronger. This is especially necessary when seeds are planted in containers on the windowsill. The lack of light is slightly offset by the fact that the mass of plants will absorb more organic matter from the soil.If we spray our tomatoes with boric acid, then the risk of infection of dense plantings with late blight is reduced.

When you take it to process tomato seedlings before planting, the seedlings will be strong and will quickly take root. But for this they make up a solution of weak concentration. Fertilizing tomatoes with a warm solution of boric acid is twice effective. It not only fertilizes, but also fights late blight and other plant diseases.

The benefits of using boron

Feeding flowering tomatoes with a solution of boric acid is very useful. It is necessary to process plants for preventive purposes.

It significantly increases the number of flowers in the plant’s brushes. And, practically, all flowers will give an ovary that will not crumble.

  1. Bor increases the resistance of plantings to fungal diseases, and reduces the occurrence of putrefactive processes on leaves and fruits to zero.
  2. Increases the sugar content of the fruits and their taste improves.
  3. With regular and proper top dressing, the ripening time of the crop is reduced.

It follows that if we take boric acid to process tomatoes and cucumbers , spraying with the drug will not only increase the yield, but also collect it earlier than in the beds application of boron.

After transplanting, we are used to water the plants more often than potassium permanganate, for the decontamination of soil and stimulate growth.But using a solution of boric acid to process our tomatoes and adding mullein, we will see that the organics will be more successfully and more fully absorbed by the plant. Weaker seedlings, compared to those that grow in the field, are grown hydroponically or in balcony boxes. Bor will give them a chance to grow strong, give abundant flowering and bear fruit successfully.

When to use boric acid

To improve germination, seeds can be processed

We know that using boric acid solution to treat tomato seeds increases their germination. But if you do not, then all the same tomato seedlings will be viable. But you need to know when you can spray tomatoes with boric acid. So that it is enough for the plants and they do not get burned, it is necessary to correctly determine the timing of plant fertilizer.

You need to start when we see that the condition of the seedlings has worsened, and there are signs of a lack of boron. The first feeding of young cucumbers and tomatoes with boric acid is carried out before the first flowering wave. If it is carried out correctly, then each flower brush will retain all the ovaries. They will be in shape, consistent with the variety, and the skin of each fruit will be smooth and shiny.

After the first flowering wave, fruit set begins and a mass of flower brushes is formed, up to 12, on one plant.Then it’s time to treat the tomatoes with boric acid a second time. Spraying the tomato with boric acid for the ovary will help preserve all the fruits and the plant will not weaken. Boron helps the movement of juice, inside the stem, which carries a huge amount of sugar, and other nutrients, to the fruits.

The third time the tomato is treated with boric acid is when the fruits are full and begin to stain. This will help the plant to fully maintain the crop and prevent the development of diseases. It is very disappointing when the tomatoes are already reddening, but at the same time, spots of rot on the fruits appear. But in order for the foliar and root dressing of the tomatoes to bring results, you need not to overdo it. you must correctly follow the recommendations for the preparation of solutions. First you need to heat the water because the crystals do not completely dissolve in cold water. Instructions are always available on the packaging of the drug, where the table contains a prescription for the preparation of solutions. A solution is prepared, and then, after cooling, liquid is added in the proportions necessary for a certain treatment.

To preserve all the ovaries, 1gr boric acid for spraying tomatoes is dissolved in a liter of very hot water. To protect the plant from phytophthora, add a teaspoon of the powder to hot water.Before this, in a week, to improve the action of boron, one can spray the plantings with weak potassium permanganate. After boron, again after seven days, a weak solution with iodine is used in the garden. If a finished preparation is purchased, then it can only be diluted to the desired concentration and used.

How to process tomatoes

How to spray tomatoes with boric acid so as not to harm the fruits? Topping tomatoes with a solution of boric acid should be done according to the rules.

  1. The first treatment of tomatoes with boric acid is carried out when the bushes are just formed, before flowering.
  2. If the flowers are pollinated, then it is forbidden to spray tomatoes with boric acid, it is better to fluff the trunk area with ash.
  3. With a weak solution, they feed the bushes when watering, which also brings a positive result if foliar fertilizing methods cannot be used.
  4. Boron concentration cannot be exceeded because its excess in the soil can destroy plantings.
  5. Before spraying tomatoes with boric acid for the second time, it is necessary that at least 10 days pass.
  6. If the condition of the plants worsens after treatment, then it is necessary to postpone the procedure or stop it altogether.

Listening to the tips and observing the development of vegetable bushes, you can find out whether to spray tomatoes with boric acid now or wait a bit.When and how to sprinkle tomatoes with boric acid, for growth or for a better ovary, tomatoes can be found on the websites by reading the table of contents.

Spray only on a calm day

When it is better to spray the tomatoes with boric acid, it also depends on the weather. On a rainy and windy day, you need to refrain from such a procedure. The solution will be blown away from the leaves and the concentration on different bushes will be different. And if the rain will wash off the boron, then yes, fertilizer will occur, but only in the form of watering. And the concentration of boron will be much less necessary for our vegetables.

For the setting of tomatoes, boron treatment will help if carried out before flowering.

Spraying iodine, plus potassium permanganate, this is a necessary procedure before applying boron. If planned treatments do not bring benefits, then the norm for subsequent ones depends on the condition of the plants. You can use foliar top dressing such as spraying your tomatoes with boric acid if you see that the leaves curl and fall off.

Precautions for working with

The main thing when working with chemicals This is what safety rules must be followed. Before you dilute the solution and apply it in horticulture or for the garden, you need to protect yourself.To protect a person, it is necessary to prepare:

  • a respirator;
  • rubber gloves;
  • an apron.

They are especially useful in a greenhouse where cucumbers and tomatoes are grown. There, the solution fumes have a high concentration and can breathe on the mucous membranes when breathing, causing irritation and burns. Why risk your health in vain?

The suspension is prepared outdoors in warm weather. The solution is poured, poured into spray guns, the face is protected using glasses and a respirator.If the treatment is carried out at home, then it is necessary to protect animals from getting the drug on them. For both humans and animals, one-time exposure to the respiratory tract will be unpleasant, but if it is reintroduced, it becomes life-threatening. Boron is poorly excreted and tends to accumulate in it.


Tomatoes and soluble boric acid, together with iodine, for their fertilizer can provide a large and tasty fruit crop. Different proportions are needed, both for root dressing, and in order to spray the plants. We told how much and what is needed to successfully grow a crop and protect it from late blight. They answered the question about how to process our tomatoes with a boron mixture, and how tomatoes and concentrated boric acid interact.Therefore, using this drug, we will be sure that we will get an abundance of delicious products to the table.
