Boric acid for the garden or. Boric acid – application for plants

Two chemical elements - orthoboric acid and iodine, in combination give a good result when spraying tomato flower ovaries. In addition, when processing the vegetative mass of adult plants, tomato bushes begin to actively grow foliage, and the fruits acquire a rich color and are characterized by a high sugar content. Experienced gardeners who have used the mixture on their plots note an increase in tomato yield by two to three times after spraying.

Advantages

Being important minerals that ensure the active growth of tomatoes, boric acid and iodine, interacting in pairs, have the following advantages:

improvement of nitrogen metabolism in plant cells;
increase in the number of fruits;
active growth of vegetative mass;
improving the absorption of micro and macro elements;
increased sugar levels in fruits;
increasing the immunity of tomatoes;
increasing the resistance of tomatoes to pathogens and infections;
ripening of the crop ahead of schedule;
increasing endurance in adverse weather conditions.

Flaws

There are practically no disadvantages when processing elements. The main thing is not to harm the tomatoes with excess fertilizing, which will cause deformation of the fruits in the plants. It should also be remembered that increased formation of ovaries will require additional application of fertilizers to the soil.

Indications for use

The combined product of two elements not only increases the number of ovaries on tomatoes. A solution of iodine and boron is also successfully used for:

stopping the growth of tomatoes due to sudden temperature changes;
rotting and death of fruits due to lack of boron in the soil;
characteristic symptoms of late blight;
the appearance of depressed dark spots of Alternaria macrospores on the fruits;
the presence of the infectious disease anthracnose on the foliage and fruits;
curling and drying of the lower leaves of tomatoes due to white spot damage;
damage to tomato foliage with chlorotic round spots due to the attack of pathogenic bacteria cladosporiosis;
the presence of gray rot on the stems of tomatoes;
infection by the pathogenic fungus septoria;
infection of tomatoes with powdery mildew;
the appearance of mosaic virus stripes on tomato foliage;
the appearance of brown flat spots in the lower part of tomato fruits due to blossom end rot.

Recipes

To get the maximum benefit from spraying tomatoes with a duo of two elements, treatments should be carried out three to four times during the entire growing season. The interval between spraying should be at least 12 days. If the tomatoes react poorly to fertilizing with elements, stop processing.

Working solutions with boric acid and iodine can be stored without losing their qualities for 25-30 days. Therefore, unused liquid can be successfully stored in a place away from sunlight.

Whey with iodine and boric acid

A combined environmentally friendly product, the use of which will improve the quality of fruits, increase productivity, and plants will actively increase vegetative mass.

Preparation:

add water and 1 liter of whey to a 5 liter container;
Heat the mixture over a fire to a temperature of + 60 degrees;
cool the liquid, add 15 drops of iodine, 1 tablespoon of boric acid;
Spray with the prepared solution in the evening once every 12-15 days. Start processing at the moment of formation of the first flower clusters.

Wood ash with iodine and boric acid

A good addition to the two components is wood ash, which contains a large amount of trace elements and minerals. And, being a natural alkali, wood ash will contribute to the death of pathogenic microorganisms.

Preparation:

Add water and 1 cup of wood ash to a 3-liter container;
leave the liquid for two days, strain;
Dilute 15 g of boric acid with 250 ml of hot water, pour into the strained ash infusion, add 15 drops of iodine;
Carry out spraying from the beginning of the tomato growing season once every 15 days.

Potassium permanganate with iodine and boric acid

Potassium permanganate steamed with iodine neutralizes the effects of infectious microorganisms and is a natural repellent against many insect pests. It also contains magnesium and potassium. These elements are necessary for the normal development of tomatoes.

Preparation:

add hot water, 1 tablespoon of boric acid, 1 g of potassium manganese to a 10-liter container;
drop 20 drops of iodine into the cooled solution, add 3 tablespoons of sugar;
carry out spraying before the formation of flower ovaries once every 12-15 days.

It should be noted that when spraying with the solution, it is necessary to carefully treat the lower part of the tomato leaves. After all, plants absorb nutrients through stomata, holes on the inside of the leaf.

Metronidazole with iodine and boric acid

By adding tablets to the two components, whose action is aimed at destroying pathogens, you can not only increase the number of tomato ovaries, but also protect the plants from being affected by many diseases.

Preparation:

Pour hot water into a 3-liter container, add 3 teaspoons of boric acid and 5 metronidazole tablets crushed into powder, cool;
add 1 glass of milk, 10 drops of iodine, 1 tablespoon of sugar to the cooled mixture;
carry out spraying from the very beginning of the tomato growing season once every two weeks.

Adhering to the recommendations of experienced gardeners who sprayed tomato flower clusters with boric acid and iodine, you can not only increase the amount of fruit formation. And also provide tomatoes with reliable protection from adverse factors, doubling the yield.

All spraying should be carried out strictly, adhering to the recommended dosages. Indeed, with an excess of iodine, increased growth of the vegetative mass will occur to the detriment of the fruits, which, due to oversaturation with the element, become deformed and become smaller.
Do not treat tomatoes with cold working solution. The temperature of the liquid that will fall on the flower brushes and foliage of the tomatoes should be at least +24 degrees.
When spraying tomatoes with boric acid and iodine, you should not forget that plants need basic fertilizing throughout the growing season. Three times a season you should fertilize with fertilizer consisting of urea, potassium and superphosphate.
To avoid foliage burns, tomatoes should be sprayed only after sunset. Before processing tomatoes, the soil under the bushes should be well watered.

Proper use and precise dosage of iodine and boric acid allows you to achieve large yields when growing tomatoes. And, thanks to this method, you can do without wasting money on expensive fungicides and complex fertilizers.

Boric acid for plants use. The use of boric acid in the garden. Pharmacy boric acid on a personal plot.

The benefits of boric acid for the garden are enormous and varied. Boric acid can be used on almost any soil, but it is especially necessary on soils with high acidity. Boron helps increase the number of ovaries, helps plant growth, increases the amount of sugar and improves the taste of fruits.

But an excess of boron can also be harmful. Different garden crops require boron in different quantities. The greatest need for boric acid is in fruit trees, cabbage and beets. Less demanding on boron: carrots, tomatoes, salads and all stone fruits. Potatoes, legumes and strawberries have the least need for boric acid.

How to prepare a solution of boric acid. It should be borne in mind that boric acid dissolves easily only in hot water. Therefore, first we dilute the required amount of powder in 1 liter of hot water, and then add the required amount of water at room temperature.

What are the signs of boron deficiency in plants:

at the apple and pear tree: leaves thicken, warp, suberization and darkening of the veins occurs; during acute starvation, the leaves fall off. Rosette leaves are observed - small leaves at the ends of the shoots are collected in the form of a rosette. In advanced cases, the tree tops die off.
at strawberry (strawberry): curvature of leaves and necrosis of edges.
near the grapes: the appearance of chlorotic spots between the veins of leaf blades, which gradually grow, the absence of normal ovaries on the racemes (crushing). A new seedling dies within a year or 1–2 years after planting in a permanent place.
in tomatoes: blackening and death of the growth point of the stem, rapid growth of new shoots from the root, while the petioles of young leaves become very brittle. Brown spots of dead tissue form on the fruits, usually in the apical area.
in potatoes: fungal scab disease, general developmental delay. The growth point is inhibited, which is accompanied by yellowing of the leaves, the petioles turn red and become brittle.
in beets: the heart of the root crop rots, which is caused by a fungal disease - phomosis. Concentric light brown spots with black dots in the center form on the leaves, then the disease spreads to the root crop and its core rots. The cut tissues initially have a dark brown, almost black color; later they dry out, become withered and rotten.

When using boric acid in the garden, you must use it correctly and follow the dosage.

Here are some tips for using boric acid in summer cottages:

Boric acid for plants:

For stimulation of seed germination use the following solution: 0.2 g of boric acid is diluted in 1 liter of water. Seeds of beets, carrots, onions and tomatoes are soaked for a day, and seeds of pumpkin, cabbage, cucumbers, and zucchini - for 12 hours.
For preparing the soil for sowing and planting use the following solution: 0.2 g of boric acid is diluted in 1 liter of water. The soil is watered with this solution before sowing seeds or planting seedlings, using a bucket of solution per 10 m2.
For foliar feeding (spraying) prepare the following solution: 0.1 g of boric acid is diluted in 1 liter of water. Three sprayings are carried out (during budding, flowering and during the fruiting period of plants). It is better to do it in cloudy weather or in the evening to avoid sunburn. When used with other microelements, the concentration of boric acid is reduced to 0.05–0.06 g per 1 liter of water.
For root feeding prepare the following solution: 0.1–0.2 g of boric acid is diluted in 1 liter of water. To prevent plant roots from suffering chemical burns, the plants are first watered with plain water. Fertilizing is carried out if there is not enough boron in the soil.
For increasing strawberry yield. To stimulate growth in early spring, pour strawberries (strawberries) with a solution of boric acid with the addition of potassium permanganate (dilute 1 gram of potassium permanganate and 1 gram of boric acid in 10 liters of water). Then, before flowering, we carry out foliar feeding with the following solution (2 g of boric acid, 2 g of manganese, dilute 1 glass of sifted ash in 10 liters of water).
For improving tree fruiting We carry out foliar feeding with the following solution: dilute 10–20 g of boric acid in 10 liters of water. Initially we spray the entire accessible crown - at the beginning of the appearance of buds, after a week we repeat the spraying. It is better to do it in cloudy weather or in the evening to avoid sunburn. This treatment reduces the number of fallen ovaries, increases the resistance of trees to unfavorable conditions, and increases the shelf life of fruits.
For increasing grape yields We treat during the budding period with the following solution: add zinc salts to boric acid (dilute 5 grams of boric acid and 5 grams of zinc sulfate in 10 liters of water) - this helps preserve flowers and reduce shedding of ovaries. And the appearance of high-quality flowers on grapes helps to avoid the problem of grape peas (crushing the berries).
For increasing tomato yields Initially, we soak the seeds before sowing in a boric solution, then we water the beds for planting seedlings with a solution of boric acid. And before flowering begins, spray the tomato bushes with the following solution: dilute 10 grams of boric acid in 10 liters of water. During the heat in the greenhouse, we refresh the tomatoes by spraying them with the following solution: dilute 2 grams of boric acid in 10 liters of water.
For reducing boron deficiency for potatoes(for the prevention of scab disease). Initially, we spray potato tubers during vernalization with the following solution: dilute 10–15 g of boric acid in 10 liters of water and spend approximately 50 ml per 1 kg of tubers. Then we feed the potato bushes with the following solution: dilute 6 grams of boric acid in 10 liters of water and use it per 10 m2 of planting. Boron is best used in combination with other fertilizers (phosphorus), and in their absence, ash can be used. 1 kg of ash contains from 200 to 700 mg of boron.
For getting healthy and tasty beets(to prevent fomosis in beets) before planting, soak the seeds for 10–12 hours in a 0.1% solution of boric acid. At the stage of 4–5 leaves, we carry out one foliar feeding with the following solution: dilute 5 grams of boric acid in 10 liters of water.
For increasing the ovaries of cucumbers, eggplants, zucchini and peppers, spraying plants with the following solution: dilute 2 grams of boric acid in 10 liters of water. We also use this solution for rotting fruits of these fruits.

Boric acid to control ants and other insects:

Boric acid is effective against ants, cockroaches and other insects. Using boric acid, various baits are prepared, which are placed in places where pests are most concentrated, but inaccessible to domestic animals.

Here are some boric acid bait options:

Sprinkling boric acid powder in those crowded places where ants are found is the simplest option, but less effective.
Pour 5 grams of boric acid into half a glass of hot water, dissolve, add a teaspoon of honey and 2 tablespoons to the solution. spoons of sugar. Mix everything, and pour the resulting mixture into a flat dish, which is best placed near ant paths.
Grind 2 egg yolks with 0.5 teaspoon. lie boric acid. Make small peas from the resulting mass and place them in problem areas.
1 table. mix a spoonful of water with 2 hundred. spoons of glycerin, add 1 teaspoon. a spoonful of honey, 0.5 teaspoon. spoons of boric acid and 1.5 table. spoons of sugar. Mix everything, roll into small bait balls. This recipe is good because the bait remains wet and soft for a long time.
3 peeled medium potatoes, boiled in their jackets, 3 boiled yolks, 10 g of boric acid, 1 teaspoon. spoon of sugar. Grind everything and mix thoroughly, roll into bait balls.

Use useful tips about boric acid.

Good luck to you!

Spraying tomatoes with boric acid for the ovary is a mandatory procedure for caring for this agricultural crop. If fertilizing containing boron is not added to the substrate in a timely manner, the flowers and ovaries on the plant may begin to die. How to treat tomatoes with boric acid for ovary - read below.

Not everyone understands that spraying homemade tomatoes with boric acid for ovaries is necessary if you want to reap a generous harvest. Very often, during the cultivation of this agricultural crop, the gardener seems to adhere to all the necessary rules and, nevertheless, is faced with yellowing of the leaves, weak flowering, and also the fall of the ovaries.

There are also frequent cases of tomatoes being infected with late blight, a dangerous fungal disease. Even if you decide to spray the plant with strong chemicals, the tomatoes may still remain lethargic and will not bear fruit very actively. The reason lies in the lack of boron in the soil.

It is simply necessary to treat growing tomatoes with boric acid for the ovary, and this procedure should not be a one-time procedure. The thing is that boron is a very useful substance for the development of tomatoes, but this component does not accumulate in the soil. At the same time, it is intensively consumed by the plant. There is only one way out: to feed the agriculture yourself.

Of course, boron is present in various nutritional mixtures. However, for full results, experts recommend using boric acid. Why is it remarkable, and why should you spray your garden plant with it? There are several key reasons for this:

the flowering phase of agriculture becomes much more intense - more flowers and ovaries are formed on the bushes;
Regular use of such an effective remedy strengthens the plant’s immunity. It becomes much more resistant to various fungal diseases - late blight, powdery mildew, etc.;
if the humidity in the greenhouse or garden is excessively high, adding boron to the soil helps prevent a putrefactive reaction;
Boric acid for tomatoes is also necessary for the ovary because it perfectly stimulates the supply of sugar to the fruit. As a result, ripe tomatoes turn out tasty in autumn, with a characteristic sweetness;
use boric acid to ensure that your crops absorb other nutrients without any problems.

What’s interesting is that if you adhere to a certain frequency in feeding your tomatoes with boric acid and at the same time observe the required dosages, you will be able to harvest from your garden about two weeks earlier than expected.

When to treat

You need to spray tomato bushes more than once if you want to achieve a certain result. It is better to fertilize several times so that the growing season is quite productive. Tomatoes need to be processed in the following steps:

wait until buds appear on the plant. This is the optimal time for the first spraying with boric acid. It is advisable to carry out the procedure before the buds open;
if you already know very well what boric acid is for tomatoes, it is recommended to spray the ovary during the flowering period of the crop;
the third stage of spraying is necessary during fruit ripening.

The use of boric acid is necessary for the ovary of tomatoes. The main thing is not only to follow the dosage, but also to understand at what time spraying the crop will only bring benefits, and when it is better to wait with such fertilizing.

How to make a solution

Many gardeners prefer to use this product in powder form. Thus, the first application of this fertilizer into open ground can be carried out at the stage of planting the plant. However, be prepared for the fact that the effect will not appear soon, since this agricultural crop absorbs the powder substance very slowly. To quickly achieve results, it is best to feed tomatoes by watering or spraying.

The standard dosage assumes the following proportions: 10 g of boric acid is diluted in 10 liters of water. Experts recommend staying at this dosage. This concentration of the substance will have a beneficial effect on the intensity of agricultural development and will not cause any harm to the health of those who are going to consume ripe fruits.

Spraying instructions

Having decided on the periods most suitable for processing tomatoes and the optimal concentration of the substance, you can thoroughly prepare for processing. All that remains is to figure out how to use boric acid to set tomatoes.

There are several ways to recharge, but it is best to focus on spraying. This technique does not require any specific knowledge: the product must be distributed evenly so that all the leaves and shoots of the tomato are thoroughly soaked in the solution.

Please take into account the following point: boron crystals must be completely dissolved in water, otherwise the plant may get burned during the spraying process. Therefore, it is best to dilute boric acid in hot water. Wait until the nutrient composition cools down, and then feel free to use it to feed the plant.

Side effects

Boric acid is very useful for tomato ovaries. If you do not want to prepare the nutrient solution yourself, it can be purchased in ready-made form at the store. It is not difficult to dilute the composition with water at home, but observe the dosage carefully. Side effects will become a reality if you add too concentrated a solution to the substrate (excess boron in the soil can even harm the plant).

Video “Processing tomatoes with boric acid”

From this video you will learn how and why to treat tomatoes with boric acid.

What are the benefits and harms of boric acid? Its use in the garden and vegetable garden is very wide. Boric acid can be used as a mineral fertilizer, a stimulator for seed germination, for lush flowering of ornamental plants and increasing the yield of strawberries, potatoes, beets and other vegetables. Boric acid can be used to protect plants from disease and scattered around the area as an ant repellent.

Boric acid - what is it?

Boron is one of the most important microelements in plant life. It normalizes the synthesis of nitrogenous substances, improves metabolic processes and increases the chlorophyll content in the leaves. Boric acid (H₃BO₃) is the simplest and most accessible boron compound. Boric acid is widely used in various complex fertilizers. It is a colorless crystalline substance in the form of flakes, odorless, easily soluble in water, acidic properties are very weak. If the amount of available boron in the soil corresponds to the norm, productivity and shelf life of fruits increase, and the overall resistance of plants to unfavorable conditions increases.

Boric acid: beneficial properties for plants

The use of boric acid helps to increase the number of ovaries on fruit and berry crops, stimulates the formation of new growth points of stems and roots, sugar content and taste of fruits.

With a lack of boron, the roots are inhibited and sometimes rot, the plant's conducting system develops poorly, the supply of nutrients is difficult, and the plant lags behind in development. Lack of boron stimulates the development of diseases - hollowness, bacteriosis. With boron deficiency, the growth point may die, and plant pollen is sometimes unable to germinate. The lack of boron is especially noticeable in dry years. And the amateur gardener, often complaining about the meager harvest, does not understand that the reason is a lack of boron. Apple trees especially require a lot of boron.

Boron in a plant is a “fixed” element - it does not pass from old, dying leaves to young ones and is required throughout the entire growing season of the plant. To use boric acid correctly, it is necessary to take into account the boron needs of garden crops. On this basis they are divided into 3 groups:

High: apple, pear, cauliflower and Brussels sprouts, beets, rutabaga.

Medium: tomato, carrots, salads, stone fruits.

Small: herbs, beans, peas, potatoes and strawberries. Although potatoes and strawberries belong to the third group, least dependent on the amount of boron, the lack of this element seriously affects these crops.

Boric acid: harmful properties in case of overdose

Boric acid belongs to the lowest, 4th class of hazardous substances. It does not harm humans if it comes into contact with the skin, but can accumulate in the body since boron is slowly excreted by the kidneys.

Excess boron in the soil is dangerous: it provokes burning of the lower leaves, drying out of the leaf edges - the leaves turn yellow, die and fall off. Symptoms of excess boron: dome-shaped leaves, curling of their edges inward, general yellowing of the leaf. Old leaves are the first to suffer. High boron content in forage plants leads to severe chronic diseases in animals.

Boric acid for ants and other insects

Boric acid as a garden insecticide is used more often as a contact preparation against cockroaches and ants, but also has an intestinal effect. Dry baits with boric acid act as contact-intestinal poisons, while wet baits act mainly as intestinal ones. The combined effect manifests itself gradually as it accumulates in the insect’s body. For example, when using boric acid, cockroaches die 8-12 days after the start of use.

Boric acid is effective against ants due to the fact that it affects the functioning of their nervous system. Once eaten, it causes serious disturbances, which after a few hours lead to paralysis and death of the insect. Even if the brothers eat the remains of an ant killed by boric acid, the same fate will await them: a very tiny amount of poison is enough to kill one ant. The simplest application is to sprinkle boric acid powder in places where ants are most often found or at the entrances to an anthill.

The option of using soft and liquid baits gives better results. When using such means, the ants eat the bait themselves and take it to the anthill, then their relatives will feed on the poison. Unfortunately, it is not possible to quickly remove ants with boric acid. Usually the process lasts at least 2-4 weeks. But this method is effective even when the anthill is located outside the site. Remember that the bait should be inaccessible to pets and beneficial insects.

Boric acid: ant bait recipes

*Pour 5 g of boric acid into half a glass of hot water (100 ml), dissolve, add 10 g of honey (teaspoon) or jam and 40 g (2 tbsp) sugar to the solution. Mix the mixture and pour into a flat container, which is best placed near ant paths. Cover the top from the rain with a piece of plastic.

* Grind 2 egg yolks with ½ tsp. boric acid, make small balls (the size of a pea or smaller) from the resulting mass and place them in key places.

*1 tbsp. mix a spoonful of water with 2 tbsp. l. glycerin, add 1 tsp. honey, 1/3 tsp. boric acid and 1.5 tbsp. Sahara. Mix everything thoroughly and roll bait balls from the mixture. This recipe is good because the bait remains wet and soft for a long time.

*3 medium boiled potatoes in their jackets, 3 boiled yolks, 10 g boric acid, 1 tsp. Sahara. Grind the peeled tubers and yolks, add boric acid and sugar to the mixture. Mix thoroughly again and roll the resulting dough into balls.

It is important to remember that increasing the amount of boric acid in the bait does not increase the effectiveness of its use - the ants will die before reaching the anthill, and the colony will simply raise other worker ants to replace it.

Boric acid: ways to use it in the garden

Preparing the soil for sowing and planting. Boric acid solution: 0.2 g of boric acid per 1 liter of water. Before sowing or planting seedlings, water the planting beds with a solution, consumption 10 liters per 10 m2, loosen and only then sow the seeds. This method is used as a preventive measure when a boron deficiency is suspected in soils.

Foliar feeding. Boric acid solution: 0.1 g of boric acid per 1 liter of water. The first spraying is carried out in the budding phase, the second - in the flowering phase, the third - during the fruiting period of the plants. When added together with other microelements, the concentration of boric acid is reduced to 0.05-0.06% (5-6 g of the drug is diluted in 10 liters of water).

Root feeding. Boric acid solution: 0.1-0.2 g of boric acid per 1 liter of water. It is used only in cases of severe starvation or a clearly known lack of boron in the soil. Plants are pre-watered with plain water to avoid chemical burns to the roots. Usually used on seedlings of flowering plants growing on soddy-podzolic soils or in a mixture of peat and sand.

Boric acid dissolves easily only in hot water! Always first dilute the sample (bag) in 1 liter of hot water, then bring it to the required volume with water at room temperature. Carry out foliar feeding (spraying) in cloudy weather, and preferably in the evening, to avoid sunburn. On hot, dry days, water the plants well beforehand.

Boric acid for strawberries

Signs of boron deficiency in garden strawberries: curvature of leaves and necrosis of the edges. Fertilizing with boric acid significantly increases the yield and improves the taste of the berries. In early spring, plantings are watered with a solution of boric acid with the addition of potassium permanganate (1 g of potassium permanganate, 1 g of boric acid per 10 liters of water), consumption - approximately 10 liters per 30-40 bushes. It is useful to carry out foliar feeding with a solution of boric acid (5 g per 10 liters of water).

Before flowering, when the plants have put out their buds, apply foliar feeding with a solution (2 g of boric acid, 2 g of manganese, 1 cup of sifted ash per 10 liters of water). Make an extract from the ash in advance: pour a glass of ash with a liter of boiling water and leave, stirring occasionally, for a day, then filter through cheesecloth - and the infusion is ready.

Boric acid for apple and pear trees

Signs of boron deficiency in apple and pear trees: leaves thicken, warp, suberization and darkening of the veins occurs; during acute starvation, the leaves fall off. Rosette leaves are observed - small leaves at the ends of the shoots are collected in the form of a rosette. In advanced cases, the tree tops die off.

In pear, rosette leaves are characterized by rapid drying of flowers and deformation of fruits, on the surface of which pits and areas of damaged tissue appear.

For apple trees, boron deficiency results in a disease called internal apple suberization. Light spots about 1 cm in diameter appear in the pulp; later they turn brown and become like a cork or sponge. Dry spotting and crusty spots affect the surface of the fruit, which becomes swollen and deformed.

Foliar feeding (10-20 g of boric acid per 10 liters of water) sharply increases fruit formation. It is held in the evening, before sunset. Spray evenly the entire accessible crown. The first time is at the beginning of the buds, the second time is after 5-7 days. This treatment sharply reduces the number of fallen ovaries, which gives an increase in yield by 25-30%. The resistance of trees to unfavorable conditions and the shelf life of fruits increase.

Boric acid for grapes

Signs of boron deficiency in grapes: the appearance of chlorotic spots between the veins of the leaf blades, which gradually grow, the absence of normal ovaries on the grapes (peas). A new seedling dies within a year or 1-2 years after planting in a permanent place.

Even a single treatment during the budding period increases the yield by more than 20% due to the preservation of flowers and less shedding of ovaries. Many people wonder why grapes have small berries. This phenomenon is called peas. The appearance of high-quality, fertile flowers helps to avoid the problem of grape peas.

Taking into account the characteristics of the grapes, add zinc salts to boric acid (10 liters of water, 5 g of boric acid, 5 g of zinc sulfate).

Boric acid for tomatoes

Signs of boron deficiency in tomatoes: blackening and death of the growth point of the stem, rapid growth of new shoots from the root, while the petioles of young leaves become very brittle. Brown spots of dead tissue form on the fruits, usually in the apical area.

As a preventive measure, soaking seeds in a solution of boric acid (0.2 g of the drug per 1 liter of water) for a day, or in a solution of microfertilizers containing boron, helps well.

Before planting seedlings, add boric acid or boron-containing fertilizers to the soil (not necessary on cultivated soils). Do not forget about foliar feeding before flowering (10 g of boric acid per 10 liters of water).

You can use foliar feeding of the same concentration in the green fruit phase to accelerate the ripening and accumulation of sugars in the fruits.

Boric acid for beets

Signs of boron deficiency in beets: the heart of the root crop rots. This is caused by a fungal disease - phomosis. Concentric light brown spots with black dots in the center form on the leaves, then the disease spreads to the root crop and its core rots. The cut tissues initially have a dark brown, almost black color; later they dry out, become withered and rotten.

Before planting, soak the seeds for 10-12 hours in a 0.1% solution of boric acid.

Apply boron to the soil to prevent fomoz. With properly prepared soil, to obtain healthy and tasty beet roots, it is enough to carry out one foliar feeding at the 4-5 leaf stage (5 g of boric acid per 10 liters of water).

Boric acid for ornamental plants

Boron helps speed up the absorption of calcium and abundant formation of buds.

For foliar feeding, use a 0.1% solution of boric acid (10 g per 10 l). When foliar feeding with boron together with other microfertilizers, the concentration of boric acid is reduced by 2 times (0.5 g per 1 l). The solution is sprayed on plants in the budding and flowering phase.

Roses. Spring spraying with a solution of boric acid in a ratio of 10 g per 10 liters gives very good results. To prevent fungal diseases, rose cuttings are immersed for 2-3 minutes. into a solution of boric acid (20 g per 1 liter of water).

Gladioli. A solution of boric acid (2 g per 10 liters of water) is used to feed gladioli in the phase of 3-4 leaves and during the flowering period to obtain larger corms.

Dahlias. Spraying with boric acid mixed with potassium permanganate (5 g + 2 g per 10 liters of water) has a beneficial effect on the development of flowering plants. Fertilizing is done 2-3 times before mass flowering in the evening with an interval of 15-20 days.

Howbuy boric acid: modern fertilizers with boron

Previously, boric acid could only be purchased in pharmacies. But now, easy-to-use boron fertilizers and packaged boric acid are available in garden centers.

It is convenient to use the drug for foliar feeding and when preparing the soil. Bor-Mag . Packaging 15-20 g (about a box) goes for 10 liters of water (per 2-3 m2).

Boric acid (B-17.5%) with brand Green Belt in a convenient 10 g package from Technoexport, it is well known to many. The drug contains boron, which is necessary for plants throughout the growing season.

Water-soluble fertilizers Pokon with boron can be found everywhere. The green bottle with a yellow cap is a long-time partner of many plant lovers: ficus, cacti and succulents, orchids, roses, palm trees, citrus fruits, flowering and ornamental foliage plants. They are quickly absorbed by plants through the leaves and root system and act immediately.

To get friendly shoots and healthy, strong seedlings, use complex fertilizer "Weaving for indoor flowers and seedlings" containing boron. It is enough to dissolve one small sachet in a two-liter bottle of water - and the resulting solution is ready for use.

For foliar feeding of apple trees, instead of boric acid, its sodium salt - borax - can be used in the same proportion. But for other crops, the sodium contained in borax is undesirable. Complex fertilizers with microelements, such as Fertika Lux . The fertilizer will be useful in February-April when feeding seedlings, in May-July for feeding plants in open and closed ground, in January-December for fertilizing flowering indoor and balcony plants.

To apply boric acid to the soil, it can be replaced with boron-phosphorus or complex fertilizer (application rate - according to the manufacturer’s recommendations). Pay attention to the wide range of fertilizers for root and foliar feeding "Intermag - Vegetable Garden" various crops: cabbage, tuberous, bulbous, flower, potatoes, tomatoes, cucumbers, strawberries and raspberries and even orchid plants.
