Boric acid how to make a spray solution. Boric acid for plants use in the garden

Without fertilizer, not a single plant will actively grow and develop. Today the choice of organic and mineral compositions for cucumbers, tomatoes and trees in the garden is so large that sometimes you forget the simplest fertilizers that you can do yourself at home. Boric acid just needed for plants, so it has found wide application among experienced gardeners.

What is boric acid

Boron plays a key role in the development of flowers, trees and shrubs, promotes normal photosynthesis, improves metabolism and synthesis of substances. Boric acid is one of the most inexpensive boron compounds that is widely used in the manufacture of fertilizers. In appearance, this acid is an odorless powder with a pronounced color. It can be used in the garden as an effective mineral fertilizer for lush flowering fruit crops, seed germination, .

Boric acid for spraying plants

Boron compounds must be used on forest soils. Such nutrition is especially important in swampy areas with a high content of carbonates or on acidic soils. Acid is also used in areas with black soil.

Signs of a lack of boron in the ground are clearly visible on tomatoes. If you see a lot of new shoots from the root, the stems are very weak and the fruits brown spots, then you need to feed the soil with boron, and even better, pre-soak the seeds in an acid solution.

Healthy vegetables after fertilizing with boron powder

Boric acid for plants application found very wide, so you can buy it to prepare a solution and increase yields. you can grow delicious and environmentally friendly vegetables and fruits if you take care of them properly.

Boric acid has found its acceptance in many areas human life. She not only bury sore ears, she is also a powerful poison for cockroaches, bedbugs and ants.

In addition, technical boric acid is effective fertilizer, which is often used in horticulture and vegetable growing. On the appearance resembles transparent scales that do not have a characteristic odor and color.

Now they began to forget about its properties a little, since a lot of modern means for plant nutrition. This drug was in demand because of its availability, effectiveness and ease of use.

Composition and purpose

The main element of this acid is boron. It has a positive effect on plant growth, accelerates metabolic processes, normalizes the work of nitrogenous compounds, increases the level of chlorophyll.

Boric acid as a fertilizer is used for:

• . berry plants,
• . potato,
• . tomatoes,
• . cucumbers,
• . pepper,
• . legumes,
• . sugar beets, etc.

This drug is an effective growth stimulant. Therefore, it is used in the process of germination seed material. Boric acid is also used as a fertilizer for indoor plants. It promotes long flowering of plants, develops their growth and protective properties.

This drug is also capable of:

• . normalize the amount of boron in the soil,
• . increase the number of fruits
• . increase the resistance of plants to sudden changes temperature regime,
• . improve frost resistance
• . stimulate the plant to form a new ovary,
• . accelerate the processes of restoration of the stems and root system of the plant after transplantation or hilling,
• . improve the taste characteristics of fruits,
• . increase sugar levels in tomatoes, corn, beets and fruits.

For what soils is this preparation used? The use of boric acid as a fertilizer is due to the fact that its composition can radically change the characteristics and functions of the soil. She is excellent remedy for plants that germinate on:

• . chernozems,
• . sod-podzolic soils,
• . gray soils,
• . flattering soils,
• . marshy soils.

Soil with high acidity works great in team with boric acid. You can fertilize plants in such soil after the soil has gone through the liming process.

The use of acid in vegetable growing

Sometimes farmers cannot understand - why do cucumbers or tomatoes stop fruiting so quickly, or why do leaves on vegetables dry out quickly? These and many other signs may indicate that there is not enough boron in the soil.

It is necessary to remember several features that appear in plants that have a lack of boron in the soil:

• . leaves and stems are stunted,
• . the process of root rot begins,
• . plant grows slowly
• . leaves begin to curl and dry quickly,
• . young leaves fall off quickly
• . dry and brown rot can be seen on the plant,
• . the roots of the plant suffer from hollowness or bacteriosis,
• . shedding of the ovary begins,
• . a small number of fruits are observed,
• . on the fruit plants leaves acquire a bluish bloom.

It is also worth knowing - which plants need boron?! The largest number boron require an apple tree, cauliflower, Brussels sprouts, pear, sugar and fodder beet.

The average need for boron is seen in: tomatoes, cherries, sweet cherries, cherry plums, carrots.

Potatoes require the least amount of boron, leguminous plants, parsley, dill, basil, strawberry.

How to dilute the drug?

The instructions for use of boric acid always indicate required amount solution preparation liquids. But before you start processing plants, you need to know that boric acid can cause leaf and root burns. To prevent this from happening, it is necessary to water the plants with ordinary water before processing.

You can also talk about a burn with boric acid:

• . yellow leaves,
• . dry stems,
• . leaves begin to curl inward.

For pre-sowing treatment seed material, boric acid is diluted with water, in the amount of 0.5 g of acid per 1 liter of water. Seeds in this solution are left for 24 hours for: carrots, tomatoes, onions and beets. 12 hours will be enough for cucumbers, cabbage and zucchini.

To prepare a solution of boronic acid, which will be used as a root dressing, use 1-2 g of acid per 10 liters of water. This amount of solution is treated with 10 sq.m. soil.

If you need to spray flowers with boric acid, then this process can only be done at the budding stage. 1 g of boric acid per 1 liter of water.

The instructions for boric acid may also indicate the standards for the preparation of poison for ants. 1 teaspoon of boric acid is diluted with 200 ml of water.

The price of boric acid fertilizer varies from 50 rubles to 85 rubles per 1 kg. In wholesale markets, it is packaged in 25 and 40 kg bags. This drug is very economical, so the average farmer for his beds 1 kg of boric acid will be enough for several seasons.

Boron is a trace element, without which plants cannot fully "breathe", assimilate calcium and synthesize biologically active substances. That is why boric acid is one of the most popular fertilizers among gardeners and gardeners who dream of a rich harvest. In addition, the drug is very effective in the fight against ants, cockroaches and bedbugs.

Boric acid

Boric acid, or H3BO3, is a finely crystalline, colorless, odorless powder. The crystals are small flakes that quickly dissolve in hot (over 70°C) water. The tool is available for use as pure form, as well as in combination with other organic top dressing. Differs in weak acidic properties and minimal danger to humans (class 4, the lowest).

Attention: an excess of boron in plants is harmful to the body - the substance can accumulate in the tissues of a person who eats food overfed with fertilizer and cause serious chronic diseases in him.

In the garden and vegetable garden

Boric acid is widely used in agriculture, however, it can only be useful if correct use. Wetlands, containing a large number of carbonates and too acidic soils.

What's the use?

The main advantages of applying the drug to the soil are:

• an increase in the ovary and, accordingly, the number of future fruits on the plant;
• improving the taste of vegetables and fruits, increasing the level of sugar in beets, tomatoes and corn;
• rapid recovery of shoots, stems and root system after hilling, transplantation and other changes;
• increased resistance to frost and drought, to temperature fluctuations;
• acceleration of growth and development of new shoots;
• increased resistance to disease;
• increase in seed germination, etc.

Signs of a Boron Deficiency

The lack of boron in the soil negatively affects garden and horticultural crops. They react differently to a deficiency of a substance, but it can always be determined visually.

1. The tops of tomatoes die off, and the formation of new stems occurs mainly at the roots. Moreover, young shoots are quite brittle and fragile. The fruits themselves are covered with brown spots in the area of ​​\u200b\u200bthe top.
2. Grapes show a lack of boron in the soil through spots on the leaves. These bald spots gradually grow, which eventually leads to the complete death of the leaf. The ovary either stops developing or completely falls off. Young seedlings may dry out during the first two years.
3. In beets, due to boron deficiency, the leaves first become stained, then they turn black, the disease affects the fruits. They rot from the inside, become inedible, with rotten flesh.
4. In fruit trees, branches can die, the ovaries fall off, and the fruits deteriorate.
5. Potatoes suffer from fungal scab - the plant slows down in development, its petioles turn red, and the foliage turns yellow.

Important: excess boron in the soil threatens plants with foliage burns. It turns yellow and curls, and then die off.

Instructions for use

Plants need boric acid in different ways - this must be taken into account when feeding. processing of decorative and fruit crops should last the entire growing season, at the time of budding and fruit formation. The proportions of boron for plants are very different.

For potatoes

Processing potatoes with boric acid can be done in 3 stages. When the tubers are sprouted and ready for planting permanent place, they can be sprayed with a 0.5-1% solution of the drug. Bushes should be treated with a spray gun over the leaf, using a 0.1% solution, and in the event of the appearance of mushroom scab, dilute 6 g of boron per 10 liters of water and feed the potatoes.

For cabbage

When 2 true leaves appear, the cabbage is treated with the following composition: 2 g of boron per 1 liter of water. It is recommended to repeat the procedure during the period of tying heads and at the time of their filling. So you can prevent the occurrence of gray rot, achieve greater density heads and increase yields.

For tomatoes

When peduncles are formed in tomatoes, but the buds are still “sleeping”, it is necessary to dissolve 10 g of boron powder in 10 liters of water and produce foliar top dressing.

For cucumbers

Cucumbers "respond" to top dressing big amount ovaries and a rich harvest. For foliar top dressing, use 5 g of the product per 10 liters of water. The procedure is carried out before flowering, and then repeated during the ovary period. If you add a couple of potassium permanganate crystals to the solution, you can get an excellent drug that fights powdery mildew.

For strawberries

Experienced gardeners claim that thanks to boric acid, strawberries become tastier and sweeter, and crop yields increase. To treat plants during the period when flower stalks are formed, dilute 5 g of powder in 10 liters of water and spray the bushes.

For indoor plants

Profuse bud formation lush bloom and a high content of chlorophyll in the leaves of indoor plants occurs after the introduction of boric acid into the soil, namely, under the root of the flower. To do this, use 0.2 g of powder per 1 liter of water. If the plant needs spraying, 3 times less acid is added per liter of water.

Ants fight

Boric acid is an excellent tool in the fight against ants. Once in the body of an insect, the drug destroys it nervous system causing first paralysis and then death. Within a month, you can get rid of the entire colony of insects in the house, including even the uterus and individuals that never leave the anthill.

There are several ways to fight: you can simply sprinkle the anthill with powder, or you can prepare a solution of 100 ml of water, 5 g of borax and 1 tablespoon of sugar / honey. Pour into a saucer and leave on the trail of insects. You can also make balls from 2 egg yolks and 0.5 teaspoon of boric acid. Lay out on the trails and near the nest.

Conclusion

Precise observance of proportions is the first rule in the use of boric acid, regardless of the form in which it is used. An inexpensive, but very useful powder is able to “make” flowers fragrant, berries and fruits ripen faster and become sweeter, and vegetables “sick” less and delight summer residents with a bountiful harvest.

For the normal development of plants, a number of useful substances and micronutrients. Boron is one of the most important. It promotes the synthesis of nitrogenous components and has a positive effect on metabolism, increasing the amount of chlorophyll in the foliage. Experts believe that boric acid can be attributed to the most accessible and simple compounds of this microelement. It is successfully used in complex fertilizers.

The active use of boric acid for a vegetable garden or garden has many beneficial effects.

What is this remedy? These are colorless, odorless crystals that quickly dissolve in the aquatic environment.

Useful qualities

This tool can be used on various soils. Nice results after application, they give gray and brown forest, sod-podzolic soils. Gardeners also recommend applying this substance to light soils, to black soil. Mandatory use of boric acid for a vegetable garden or garden on acidic, swampy or dark-colored soils.

This tool perfectly helps to increase the number of ovaries, significantly increases the yield. After the use of boric acid for a vegetable garden or garden, it is actively developing root system and plant stem. The amount of sugar increases, improves taste qualities fruits.

Boron is a "fixed" element in plants. He cannot go from old withering leaves to young ones. Therefore, it is necessary for plants during the entire growing season.

Experts know that everything horticultural crops need boron in varying amounts. We will conditionally divide all of them into 3 groups of needs:

• small (strawberries, potatoes, legumes);
• medium (tomatoes, carrots, stone fruits);
• high ( fruit trees, beets, cabbage, swede).

Although potatoes and strawberries belong to the group with a low need for this trace element, its deficiency can adversely affect these crops.

Signs of boron deficiency in plants

Not only acidic soils, but also soils with high humidity. The lack of this substance in plants affects in different ways. Corn and potatoes practically do not need additional application. But if this trace element is not enough, then the leaves of the potato begin to turn yellow, tubers do not develop, and cracks appear on their surface.

A lack of boron in plants can also lead to the development of diseases - brown and dry rot, baketriosis, and bulging. The following signs indicate a lack of this microelement in the soil:

• the kidneys dry up;
• plant stems become crooked;
• growing points die off;
• plant leaves become curly, pale;
• flowering is absent.

These signs are especially pronounced in dry seasons. Many amateur gardeners, when harvesting a small crop, blame it on the lack of moisture, and not the lack of essential trace elements in the soil.

Ways to use in the garden and in the garden

The benefits of boric acid are invaluable and quite diverse. But you should be careful with this element, because an excess can harm the plant, accumulating in the fruits, like other fertilizers. Therefore, before you get a positive effect from the use of boric acid for a garden or vegetable garden, you should pay attention to the advice of experienced gardeners. The main task is to observe the dosage and apply the drug correctly.

Consider these methods of using boric acid:

• stimulation of seed germination;
• soil preparation for planting;
• foliar planting;
• top dressing at the root.

Boric acid is actively used to stimulate seed germination. How to breed this remedy correctly? It is necessary to take 0.2 g of powdered agent for 1 liter of water. The crystals dissolve quickly. Seeds are soaked in this solution:

• onions, carrots, beets - for 24 hours;
• cucumbers, cabbage, zucchini - for 12 hours.

How to dilute boric acid for sowing or planting? Everything is the same: in proportion to 1 liter of water - 0.2 g of the product. Planting beds should be shed with this solution. Consumption: 10 l per 10 m2. Then the soil should be loosened and then the seeds should be planted. This method is used if there is a suspicion of a lack of this microelement in the soil.

Boric acid is very important. Solution concentration: per 1 liter of water - 0.1 g of boric acid. The first spraying is carried out at the stage of bud formation, the second - at the flowering stage, the third - at the fruiting stage. Sometimes other drugs with boric acid are used together. For spraying in this case, take a smaller dose (5-6 g per 10 liters of water).

Foliar top dressing with boric acid should be carried out in cloudy weather. Experienced gardeners always postpone this procedure for the evening to avoid sunburn. If you need to spray on hot days, you should first water the plant.

Top dressing with boric acid under the root is used quite rarely. In this case, you should make sure that the soil really lacks this element. Most often this procedure is used for seedlings. flower plants, which grow on a mixture of peat and sand or sod-podzolic soils. The solution is prepared using 0.1-0.2 g of the drug per 1 liter of water. But first, the plant is abundantly watered with plain water to avoid chemical burns.

Remember that boric acid is highly soluble in hot water. First of all, it is necessary to dissolve 1 sachet of the drug in 1 liter hot water. After that, the solution should be brought to the desired volume by mixing with water at room temperature.

Potato processing

The following factors indicate the lack of boron in potatoes:

• general developmental delay;
• fungal scab disease;
• the point of growth is oppressed;
• leaves turn yellow;
• petioles turn red, become brittle.

The need for potatoes in boron directly depends on the soil, or rather, its acidity. Also, this indicator is affected by the temperature and the ratio of minerals contained in the soil. If an amateur summer resident exceeded the norm during the introduction of nitrogen and potassium, then the plant's need for boron increases significantly. If the dose was increased phosphate fertilizer- the need is reduced.

If the first signs of scab damage appear on the potato, it is necessary to use boric acid at the rate of 6 g per 10 liters of water. To prevent this disease, it is necessary to spray potato tubers at the stage of the appearance of the first shoots.

Beet processing

A lack of boron in beets causes wormholes and core rot. Often these lesions are caused by fungal disease- phomosis. At the same time, concentric light brown spots appear on the leaves, in the center of which black dots are placed. After the disease passes to the root crop. On the initial stage on the cut, the tissues of the root crop have a dark brown color. In the future, the affected parts dry out and become rotten.

Before planting, seeds should be soaked in a solution of boric acid. It must also be applied to the soil to prevent the appearance and development of phomosis.

If the soil and seeds are properly prepared, to obtain good harvest it is enough at the stage of 4 leaves to spray beets 1 time with boric acid. As practice shows, the result will be excellent.

Processing of tomatoes

Lack of boron in tomatoes also causes various diseases. Young leaves and branches begin to grow only from below, the base turns black and becomes brittle. In other words, the tomato turns into a bush. Brown spots appear on the fruits, the pulp becomes dry. Some summer residents use a solution of boric acid from phytophthora.

For prevention, before planting, the seeds must be soaked in a solution. Before planting, this solution is also introduced into the soil. Care should be taken to carry out foliar feeding before flowering. Boric acid has a positive effect on the tomato ovary.

To accelerate the ripening and accumulation of sugar, you can re-spray with boric acid at the stage of green fruits.

Cucumber processing

Boric acid for cucumbers is also actively used. This element helps the plant in the process of flowering and ovary.

To improve the ovary, prevent rotting of zucchini and zucchini, a solution is also used: 2 g of the product per 10 liters of water. Plants are sprayed with it.

Use the same boric acid solution for peppers and eggplant.

Pear and apple processing

Signs of a lack of boron in pear and apple trees:

• leaf thickening;
• darkening and corking of the veins;
• leaves warp and fall;
• small leaves at the ends of the shoots are collected in the form of a rosette;
• the top of the tree dies.

These signs contribute to the rapid drying of flowers, deformation of fruits, on which traces of affected tissues appear.

Light spots appear in the pulp of apples, which gradually turn brown and turn into a sponge.

Foliar top dressing (10-20 g per 10 liters of water) will help restore the lack of boron. Spray evenly throughout the crown. The first time - during the opening of the buds, the second - a week later.

Grape processing

The lack of boron is evidenced by chlorotic spots between the veins on the leaf, the absence of good ovaries. On soils with a minimum amount of this trace element, new seedlings die within 1.5 years.

Strawberry processing

With a lack of this element, strawberry leaves become dry. To improve crop quality in early spring a solution of boric acid and potassium permanganate should be poured onto the plantings (for 10 liters of water, 1 g of each drug).

Before flowering, it is also desirable to carry out foliar top dressing with a solution: 2 g of boron, 2 g of manganese and 1 cup of sifted ash per 10 liters of water.

Processing of ornamental plants

This microelement contributes to the rapid absorption of calcium and the abundant formation of buds. That's why experienced gardeners, actively use this tool to get a beautiful, blooming garden. During the period of bud formation and flowering, foliar treatment is carried out (10 l of water per 10 g of the preparation).

Rose cuttings are immersed for several minutes in a boron solution to prevent fungal diseases.

drug overdose

Boric acid belongs to the lowest, 4th, hazard class harmful substances. In case of contact with the skin, this drug does not harm human health. The danger lies in the fact that this element accumulates in the body, because it is slowly excreted by the kidneys.

Boron can be a panacea, and maybe a poison for plants. After all, an excess of this drug provokes a leaf burn. They dry out, die and fall off. Symptoms of an excess of boron in the soil are yellowing of the leaves, folding their edges. The leaves often take on a round shape.

The high content of this substance in fodder plants provokes the development of serious diseases in animals.

Insect control

Boric acid is not only useful tool for plants. This drug helps fight harmful insects. Often use dry mixes with boric acid from ants in the garden. This element accumulates in the body of insects and negatively affects their vital activity, which subsequently leads to death.

Boron acts on the nervous system of the ant, causing paralysis and further death. When eating the corpses of their fellow ants, other ants also die. Therefore, to get rid of ants in the garden, very little boric acid is needed.

In order to remove these insects completely, it is necessary to use such a mixture within 1 month.

Ant bait recipe

There are many recipes using this drug that help get rid of insects. We will consider the most popular:

1. Boil 2 eggs for 30 minutes. Take out the yolks and grind them with the addition of 0.5 teaspoon of boric acid powder. Scatter the resulting balls near the anthill or on the path of the ants.
2. Dissolve 5 g of the above preparation in 100 ml of hot water. Add 10 g honey, 40 g sugar. Mix everything and pour into a jar. Cover with a lid to leave small passages. Put dishes near the anthill.
3. 1 teaspoon of sugar, 3 egg yolks (boiled), 10 g of dry boric acid, 3 boiled potatoes. All grind and mix. Make small balls and put near the anthill.

For gardeners, boric acid is an excellent tool to help grow plants. The tool increases productivity and activates the formation of ovaries on plants. In this case, the main thing is to know exactly what the use of boric acid for plants should be.

Why is boric acid useful for plants?

The use of boric acid in growing plants has certain advantages.

The substance has the following positive effects on plants:

• growth stimulation;
• increase in the volume of chlorophyll;
• increasing the rooting ability of seedlings;
• strengthening bushes;
• ovary activation.

When spraying plants with a solution of boric acid, it is possible to increase the survival rate of plantings under adverse conditions. weather conditions, at the time of a dive or when diseases and pests appear in plants. Also, the substance increases the sweetness of the fruit, which makes the harvest tastier.

It is very difficult to harm plantings when using boric acid, which is why the remedy is recognized by most gardeners as the safest. However, you can also overfeed the plants with boric acid, in which case the leaves will take on a domed shape (their edges will be bent down). Eating a crop supersaturated with boron is also not healthy, which is important to consider. Boric acid for plants is a mandatory fertilizer, which, like everything else, should be used in moderation.

Signs of a lack of boron in garden and garden plants

It is possible to determine that a plant is experiencing boron deficiency by a number of signs. It is not difficult to notice them even for a novice gardener. The deficiency in the soil of a substance is evidenced by some changes that occur with crops.

• The leaves of the trees thicken significantly, and their deformation occurs. Seals are usually in the form of spots. Gradually, the leaves turn yellow and die. If the boron deficiency is particularly severe, then the whole top of the tree may die off. Spots form on the fruits, and tubercles in the upper part.
• If boron deficiency occurs in grapes, then spots develop on its leaves, in areas between the veins, which gradually spread to the entire sheet plate and lead to drying out. Falling of the ovary may also occur. When young shoots do not receive enough boron, the probability of their death in 2-3 years is high. This process looks like gradual fading vines.
• Tomatoes react to a lack of boron by dying off the tops. At the same time, a large number of new shoots appear closer to the root, which are particularly brittle.
• It is not uncommon for potatoes to suffer from a deficiency of a substance. Most often, during starvation, the plant is affected by scab of a fungal nature. The bushes are far behind in development, their leaves begin to turn yellow, and the petioles, in turn, turn very red. The phenomenon occurs when hyperacidity soil or excessive use of potash and nitrogen fertilizers.
• Beetroot reacts to a deficiency of a substance by developing phimosis. At the beginning of the disease, only the leaves of the culture suffer, on which dried spots form. Further, the disease spreads to the root crop - it begins to rot from the inside. On its section, a black flabby core is visible. There is no such beet.
• Flowers with a lack of boron in the soil begin to lay small buds, and the intensity of the color of the flowers is significantly reduced. Perennial crops gradually wither, and annuals wither ahead of schedule.
