Correct use of boric acid for spraying tomatoes

Correct use of boric acid for spraying tomatoes


Caring for cultivated plants on the garden plot is not limited to planting and harvesting. The main thing is timely watering, protection from diseases and plant nutrition for growth and increased yields. Tomatoes, like other crops, are very sensitive to fertilizers and respond with abundant flowering, increased ovaries and rich fruiting. Boric acid is one of the unique dressings. It not only provides tomatoes with such an indispensable trace element as boron, but also effectively fights late blight of tomatoes when spraying.

What is the processing of tomatoes with boric acid for?

For normal development and optimal fruiting, plants need a lot of nutrients. The uniqueness of boron lies in the fact that it helps to take from the soil all necessary micro and macro elements.

Boric acid is a white crystalline powder that has no taste or smell, easily dissolving in warm water. Boron is a part of many ready-made fertilizers, primarily used for seedlings, as it improves its nutrition, more complete absorption of nutrient organic and mineral substances from the soil, thereby creating a good base for further plant development.

Vegetables and fruit crops absorb much more boron than, for example, cereals. Therefore, it is successfully used to process or feed cucumbers, potatoes, beets, strawberries, grapes, pears and apple treesin the greenhouse and in the open field.

Boric acid is very effective in combating late blight, Moreover:

  • actively affects the flowering of plants, enhancing it;
  • promotes the formation of ovaries and prevents them from shedding;
  • prevents tomatoes from rotting with excess moisture;
  • increases the flow of sugar to fruits, seeds.

For tomatoes, boron feeding is especially useful; it is carried out in two ways:

  • foliar spraying of the ground part tomatoes with boric acid solution;
  • watering the bushes with a solution under the root (for tomatoes and cucumbers).

Spraying has a better effect on tomato plants: it stimulates the growth of the root system and stems, improves metabolic processes, the synthesis of nutrients, and increases the level of chlorophyll. All this makes the plant stronger and more resistant to various diseases.

Such feeding is especially useful for tomatoes grown at home - in flower pots or on the balcony, since they are more weakened than ground congeners, requires increased nutrition.

Spraying with a boric acid solution allows you to increase the yield of tomatoes and significantly improve the taste due to an increase in the sugar content of the fruits.

When feeding is carried out

During the entire growing season, feeding is carried out several times. Even before sowing, the seeds are soaked in a nutrient solution for a day. To do this, 0.2 g of powder must be diluted in 1 liter of very warm water - 50-55 degrees (in cooler water, boric acid powder dissolves for a long time and not completely). The seeds are dipped into the solution in a gauze bag so that they do not float to the surface.

Such seed treatment significantly increases their germination, strengthens seedlings, contributing to a more complete supply of nutrients, protects against diseases even in high humidity.

Subsequent spraying is carried out 3 more times:

  • during bud formation;
  • during the period of mass flowering;
  • at the stage of the beginning of fruiting.

Between dressings must pass at least ten days... If the plants reacted well to the first treatment, it is advisable to carry out subsequent ones, and if not, it is better to refuse and not water with this type of fertilizer.

The ready-made solution for spraying (see the recipe below) should be sprayed from a spray bottle directly onto the leaves, stems, buds, flowers and fruits of tomatoes. Such feeding much more efficientthan watering at the root, as it ensures the rapid absorption of boron by the plant. The result is noticeable already literally on the second or third day after treatment.

Spraying tomatoes should be carried out exclusively in the morning, evening or in cloudy weather to avoid direct sunlight during the treatment period, otherwise the plants get burned and may dry out.

Such a simple and cheap way will help to harvest a rich harvest of delicious sweet tomatoes and improve their keeping quality, which is very important for preserving the harvest.

Signs of a boron deficiency in a tomato

By the appearance of plants, it is easy to determine that they are deficient in boron:

  • upper (but not lower) leaves of bushes turn yellow, curl, become small, deformed;
  • apical shoots gradually die off, since nutrients do not enter the plants;
  • tomato bushes bloom very weakly, ovaries are not formed, a large number of barren flowers, small ovaries fall off.

Treatment of tomato plants should be carried out only with a warm solution of boric acid! Water and soil temperatures must be the same.

Useful properties of boric acid for tomatoes

The tomato is one of the most popular fruits in a vegetable garden or garden plot. It is difficult to overestimate the benefits of boric acid for their nutrition and cultivation. We can say that the future harvest of tomatoes largely depends on boric acid, because it has a positive effect on the entire vegetation process plants:

  • strengthens, nourishes seedlings;
  • activates flowering;
  • increases the number of ovaries;
  • prevents fruit from rotting;
  • promotes the transport of sugar along the stems, increasing the sugar content of the fruit.

Instructions for preparing spray solution

To prepare the solution, it is necessary to observe some subtleties and follow the instructions for use and use. Dilute boric acid powder (approximately 0.5 teaspoon without top) in a glass of hot water to dissolve it quickly and completely, and then add it to 10 liters of water, stir, and spray the tomatoes with this ready-made solution.

Depending on the purpose of processing, different proportions are used:

  1. To prevent shedding of the ovaries, 1 g of boric acid is dissolved in 1 liter of hot water... After the solution has cooled down, the tomatoes are sprayed with a spray bottle.
  2. To combat late blight add 1 teaspoon of powder to a bucket of warm water and process the plants. To achieve the best result, it is recommended to spray the tomatoes with a weak solution of potassium permanganate a week before, and a week after treatment with boron - a weak solution of iodine.

Treating tomato plantings with boric acid is the most effective and cheapest way to get a healthy and abundant harvest. The main thing is not to overdo it, strictly observe the proportions, and the excellent result will delight you.


Members of the nightshade family prefer fertile, rich soil. With a lack of mineral elements, the yield is significantly reduced. Lack of boron in the ground is fraught with the death of fruits already at the first stage of flowering. The role of the substance in the process of growing tomatoes:

  • improves the access of calcium to the plant
  • participates in the process of pollination
  • ensures the safety of flowers and their development
  • accelerates cell growth
  • essential for the formation of plant cell walls
  • necessary for transporting sugar to developing berries
  • takes part in photosynthesis.

In conditions of boron deficiency, the development and growth of tomato is disrupted, the possibility of a good harvest disappears. Fertilizing tomatoes with boric acid is an essential key to success.


The benefits of iodine for tomatoes

The main property of an alcoholic solution of iodine is instant disinfection. The remedy is often used to cauterize open wounds.

Gardeners have long been using iodine as a fertilizer, but it has gained the greatest popularity among greenhouse owners. It is believed that this pharmaceutical product does not harm either the plant or people.

Iodine is an optional component for plant growth, but its lack negatively affects the development of ovaries and the formation of fruits. Young plants especially need this element.

Signs of iodine deficiency

A deficiency of a substance can be recognized by the following manifestations:

  • plants have thin stems
  • leaves are weak and lethargic
  • mature plants do not enter the fruiting stage
  • a small number of ovaries
  • prolonged ripening of fruits
  • massive damage to seedlings by diseases - root rot, brown spot, late blight and tobacco mosaic virus.

If the lack of an element is not eliminated, plants begin to suffer from a decrease in immunity and, as a result, the development of various diseases caused by pathogens. The tool serves as an additional fertilizing of the soil, helps to accelerate the growth of seedlings and helps to save the harvest in case of disease.

The effect of iodine on seedlings

The active components of the element improve nitrogen metabolism, which makes it possible to fertilize seedlings without the use of nitrate. The pharmaceutical agent is also known for its fungicidal properties: experienced summer residents use it both as a prophylaxis for various diseases and for disinfecting seeds before planting. It has been proven to help fight fungal and bacterial diseases in tomatoes.

Tomatoes react actively to aggressive components of iodine. The effect of fertilizing and spraying is not long in coming - the plants begin to grow rapidly. In addition, the number of ovaries and fruits increases.


In what proportion to spray tomatoes with boric acid?

This supplement is sold in the form of a white powder that dissolves well in water. To get the correct composition, you need to act step by step, as mentioned earlier. With boric acid, a tomato feeding recipe can be used for root watering and spraying. In the second cases, the solution will be less concentrated, so 5 g of powder should fall on 10 liters of water.

Foliar feeding of tomatoes with iodine and boric acid

An excellent combination product that will help increase yields. The procedure is recommended when the bushes have faded and they pass into the fruiting phase. In addition to the fact that processing tomatoes with boric acid and iodine will help improve the quality of the fruit, it will also protect against many fungal diseases.

  1. For a simple solution, dilute 5 g of acid in 200 ml of warm water, and then add 10 drops of iodine there. Dissolve the mixture in 10 liters of cold liquid. Spray with the solution, paying attention to the leaves.
  2. The following composition is safer: dilute 5 g of acid in hot water, and then dilute in 10-15 liters of cold liquid. Spray, and after a week repeat the procedure, but with a different solution: 10 liters of water, 1 liter of milk and 15 drops of iodine.

Foliar feeding of tomatoes with ash and boric acid

Wood ash, which contains many useful minerals, is an excellent additive. In addition, it is an excellent tool for pest control. For spraying, ash and boric acid for tomatoes are mixed as follows:

  1. In 200 ml of hot water, you need to dilute 10 g of boric acid.
  2. Mix 2-3 liters of water and 1.5-2 liters of wood ash separately, and then stir well. Pour the prepared acidic solution there and bring the volume to 10 liters.
  3. It remains only to add 10 ml of iodine and mix everything thoroughly. The ready-made composition is best used for root feeding, but spraying of bushes is also possible. 1.5-2 liters should be consumed per bush. Repeat the procedure once a week.

Top dressing of tomatoes with boric acid and potassium permanganate

Manganese has a myriad of benefits that are essential for vegetable crops. It is an excellent protection against pests and diseases, and also contains potassium and magnesium, which are beneficial for plants. Processing tomatoes with boric acid and potassium permanganate can be carried out according to the following scheme:

  1. In a slightly pink solution of manganese, dilute the acid, the amount of which should be on the tip of the knife. Apply the prepared product before flowering, which will increase the yield and enhance the taste of the fruit.
  2. There is another option for spraying: mix 10 liters of water, 2 g each of potassium permanganate and boric acid, and add 1 teaspoon of iodine and 1 tbsp. ash.

Boric acid, iodine, potassium permanganate, milk for tomatoes

This complex feeding combines several useful products at once, thanks to which it is able to increase the number of ovaries on tomatoes and leaves, and also protect them from diseases. For tomatoes, boric acid is combined with milk and other components in a certain proportion.

  1. Dissolve 1-1.5 g of acid in hot water, but not in boiling water. Then add the manganese on the tip of the knife. The result should be a dark pink solution.
  2. Add 200 g of homemade milk or 250 g of commercial milk. In the next step, pour in 1.6 cubes of iodine with a syringe.
  3. The last component is urea, which should be taken 1 tbsp. spoon. Mix everything thoroughly, and then dilute the resulting solution in 10 liters of water. It remains only to spray.
  4. You can do the treatment with such a tool 2-3 times per season. The whole plant should be sprayed.


How to properly prepare a solution

To make the solution useful for plants, adhere to the established proportions and follow safety rules.

Proportions

Mix boric acid powder, sugar and water: 2 tbsp. l. boric acid and 2 glasses of sugar for each glass of water. Sugar will attract pests including ants and cockroaches, while boric acid will kill them.

Advice! Use hot water to dissolve the acid quickly.

Recipes

Boron has disinfectant properties. In the fight against late blight, gardeners use an antiseptic solution to treat bushes: 10 g of the drug are dissolved in 10 liters of hot water and 20 drops of iodine are added. The solution is sprayed onto the stems and leaves.

Folk remedies will saturate plants with potassium and help get rid of bacterial and putrefactive diseases, such as black leg, root rot. Take 2 g of boric acid, 1 tbsp. l. urea, 2 g of potassium permanganate, half a glass of ash, dilute in 10 liters of water and water the plants. Potassium permanganate will help sterilize the soil from harmful flora, ash deoxidizes the soil well.


The role of boron in the growing season of tomatoes

During the growing season of tomatoes boron:

  • takes part in the construction of the cells of the walls of the vegetable
  • controls the supply of calcium to the plant. A lack of this element can cause a disease such as apical rot.
  • positively affects the growth of each part of the tomato, as it is responsible for the process of growing the tips of stems, leaves, and also roots
  • affects the rate at which new cells appear
  • controls the process of transporting sugar from ripe tomato points to developing
  • helps the growth of fruits, the laying of new buds, and also contributes to the successful pollination of plants
  • takes part in the process of photosynthesis.


Tips from experienced gardeners

During the preparation of solutions, do not exceed the dosage of the drug. Observe the frequency of spraying. Follow these tips to get a good tomato crop:

  • top dressing is effective regardless of the type of soil on which the vegetable crop grows
  • dilution rule - boric acid dissolves only in warm water
  • do not use an alcohol solution of a medicine for feeding
  • perform unscheduled treatments at the first sign of boron deficiency.

Subject to all the rules and instructions, gardeners note the active growth and development of tomatoes. Seedlings adapt faster in open and closed ground. Fruiting is accelerated - 7-10 days earlier than the date specified in the description of the variety.

Top dressing is carried out regularly throughout the growing season. With proper care, the vegetable crop does not lag behind in growth, blooms well and bears fruit before the onset of the first frost.
