How to treat with boric acid. Boric acid: application in the garden and in the garden

Boric acid is not only a stimulant for the formation of the ovary, but an excellent fertilizer for the garden. It is used for many crops: potatoes, tomatoes, cucumbers, raspberries, strawberries and so on. Therefore, if you find a bag of leftovers in your stocks boric acid, do not rush to throw it away, but feed your green pets.
With a deficiency of boron in garden and garden plants growth points die off, ovaries fall off, leaves dry up and roots die. With such symptoms, fertilizing with boric acid can help.

Boric acid for garden plants

On the side shoots of raspberries, the bulk of the crop is tied.

Boric starvation in raspberries is manifested in the fall of the kidneys in early spring. As a result, lateral shoots are not formed and the yield of plantings drops sharply.

With such symptoms, it is useful for plants to give outside root dressing boric acid solution (10 grams per 1 liter hot). Generally speaking, throughout the season, every 10-15 days it is good to feed raspberries alternately with a solution of urea (10-15 grams per 10 liters of water) and a solution of boric acid.

Boron is abundant in organic substrates like manure, compost and humus. Therefore, where they are applied on a regular basis, there is no additional need for boron fertilizers.

Boric acid is also used in foliar applications with micronutrients. different types currants and gooseberries. For 10 liters of water, 5-10 grams of potassium permanganate, 2-3 grams of boric acid and 30-40 grams of blue vitriol. Each substance is mixed with water separately, then the solutions are combined and sprayed garden shrubs in June-July.

With a lack of boron, the apple tree has a weak fruit set and tissue corking. The leaves grow small, dense, and the shoots branch strongly. The problem can be corrected by applying borax (400 grams per mature tree, preferably in autumn).

Boric acid for tomatoes

Tomatoes are sprayed with a solution of boric acid to stimulate fruit set. This operation is carried out in the phase of partial opening of flowers on the second inflorescence.

To prepare a solution, 1 gram of boric acid is dissolved in 1 liter hot water. Tomato bushes are abundantly moistened from a garden sprayer in the morning or evening hours.

Boric acid is also effective in combating late blight. To this end, it is bred and used in a slightly different way. You can read about this in the article "".

Boric acid for cucumbers

Boric acid and other trace elements are added to the second dressing of cucumbers, which is carried out during the period mass flowering plants. To do this, for 10 liters of water, use 1 liter of cow's or horse manure(0.5 liters), 0.5 grams of boric acid, 0.4 grams of manganese sulfate, 0.1 grams of zinc sulfate.

With the help of this drug, education is also prevented. In this case, the solution is prepared in exactly the same way as for processing a tomato garden (1 gram of boric acid per 1 liter of hot water). Spraying is carried out in quiet, dry weather in the morning or evening.

Boric acid for strawberries

Spraying strawberries with boric acid promotes better fruit set and improves their quality (berries are smooth and beautiful).

The first leaf treatment is carried out in early spring (at the very beginning of growth) with the following composition: 40 grams of urea, 10 grams of iron sulfate, 15 grams of boric acid, 20 grams of citric acid and 1 teaspoon of iodine per 10 liters of water.

To prepare the solution, dilute the urea, citric acid and boric acid in different dishes, bring the volume of liquid to 10 liters and add iodine at the end.

Good result gives an alternative recipe: for 10 liters of water, take 1 teaspoon of potassium permanganate, boric acid, copper sulfate, iodine and baking soda.

During flowering and fruit set, it is useful to spray strawberries with a 0.15% solution of boric acid (1/3 teaspoon per 10 liters of water). In total, 1-3 such sprayings are carried out.

Boric acid for potatoes

Boric acid is used to prepare a solution for soaking seed tubers, as well as for root and foliar top dressing of adult bushes.

For soaking planting material 10 grams of superphosphate, 0.2 grams of potassium permanganate, 1 gram of boric acid, 1 gram of copper sulfate and 0.2 grams of Kornevin are diluted in 5 liters of hot water. The tubers are dipped into the solution for 20-30 minutes before planting. The same nutrient composition is moistened with sawdust intended for preplant germination of potatoes.

The first spraying of the potato field with boric acid is done at the beginning of budding and then repeated 2 more times with an interval of 10 days. To do this, 2 grams of copper sulfate and 10 grams of boric acid are taken per 10 liters of water.

During the summer, you can also carry out one top dressing with a solution of boric acid under the root. To do this, 2 grams of this substance is diluted in 10 liters of hot water and 1 liter is spent for each potato bush.

Boric acid for other vegetables

Celery root and turnips will grow large and tasty if you treat the plants with boric acid.

Root celery is sprayed with a solution of this drug in the phase of 4-5 true leaves. The solution is prepared at the rate of 2 grams of boric acid per 10 liters of water.

Turnips are fed leaf by leaf with the same solution 2-3 times during the growing season.

To improve the quality and size of heads cauliflower sprayed with a solution of trace elements in the seedling phase and water the plants under the root before setting. In both cases, the following recipe is used - 2 grams of boric acid and molybdenum ammonium per 10 liters of water.

Boric acid is a useful and affordable fertilizer that increases the yield and quality of fruit and vegetable products.

And how do you apply boric acid on the site? I’m sure I didn’t remember all the ways to use it.

Pharmaceutical boric acid contains 17% boron - an indispensable trace element for any plant. We will learn how to properly use the drug in the garden and flower garden, so as not to harm the plants and our own health.

The benefits of boric acid in the garden

In medicine, boric acid is used as an antiseptic. The substance is used in industry, photography and jewelry.

Gardeners have long learned to use boric acid at all stages of growing plants, from soaking seeds. Boron accelerates the metabolism in the plant, increases the production of chlorophyll, and improves tissue respiration. After the introduction of boron on fruit and berry crops, the number of ovaries increases, the fruits become sweeter and tastier.

Boron in the plant does not flow from old leaves to young ones, therefore it is required during the entire growing season.

The lack of boron in the soil is noticeable in dry weather. Plants that lack an element stop growing upwards. The development of lateral shoots, on the contrary, is enhanced. On young foliage, the veins turn yellow, appear yellow spots. The leaves become smaller, wrap and fly around. The fruits are deformed. With a lack of boron, potash fertilizers are worse absorbed.

Top dressing with boric acid is useful on any soil, even on black soil. They are especially important after liming acidic soils.

Boric acid in the garden is used as a disinfectant seed and for feeding adult plants. For soaking seeds 2 gr. funds are diluted in 1 liter of water and incubated for 24 hours. Seeds of pumpkin and cabbage are soaked for only 12 hours.

Different plants need boron to varying degrees:

strongly need - cabbage, beets;
need medium - greens, most vegetables;
need a small degree - legumes, strawberries, potatoes.

Although potatoes and garden strawberry can do with a modest amount of boron in the soil, the lack of a trace element affects crop yields.

The leaves of the potato die off, the peel of the tubers becomes rough, cracked, dead patches appear on the pulp. If potatoes are grown on acidic, podzolic, limed soil, be sure to root-dress the seedlings with boric acid - this will completely eliminate the scab.

Solution preparation

Do not dissolve the drug in cold water. In order not to heat a large volume of liquid, use a little trick. First, dissolve in a liter of water heated to 70-80 degrees, required amount acids. Then pour the mother liquor into a ten-liter bucket filled with cold water.

The drug is released in pharmacies in sachets of 10 gr. If 1 g is required, the contents of the sachet should be poured onto a flat surface and carefully divided into 10 equal parts.

Foliar top dressing is carried out in the evening or in warm cloudy weather, using a fine sprayer. Plants are sprayed until drops begin to flow to the ground. Potatoes and strawberries can be watered under the root.

Boric acid analogues

IN garden shops you can buy modern fertilizers with boron:

Green Belt– packing on 10 gr;
Mag Bor- contains calcium, magnesium and boron, packing 100 gr;
Kelkat Bor– packing on 20 kg.

Ant breeding

The tool is used in household for removing cockroaches. In the garden with it, you can get rid of ants. For insects, boric acid is a contact-intestinal poison. Accumulating in the body of an insect, it stops working nervous system and leads to paralysis. The simplest use of the product is to sprinkle the powder at the entrance to the anthill.

Bait preparation:

Mix ½ teaspoon of acid with two boiled egg yolks.
Roll into pea-sized balls and place next to the anthill.

Boric acid - good feeding for fruit trees, berries, vegetables and flowers. Boron is involved in the most important life processes of garden and horticultural crops. Fertilizer is sold both in solution format and liquid boric acid, both of these forms are used for plants.

For plants, the correct absorption of calcium, the synthesis of the necessary substances and root respiration are vital. Boron contributes to all this. Professionals apply fertilizers based on it during the entire growing season about 2-3 times. The widespread use of boric acid in horticulture and horticulture is due to the low price of top dressing, ease of use and versatile spectrum of action. Seeds soaked in an acid solution germinate better, seedlings grow faster, and seedlings become stronger. The number of ovaries increases, the plants produce more fruits.

Why is boric acid useful for plants?

Boric acid powder dissolves in water heated above 70 degrees. Grains that do not dissolve in colder water can cause burns to plants. As a result, more often used foliar top dressing sprayer having the "drizzle" mode. The treatment of plants with boric acid is carried out in the evening without strong wind and expected rain. This gives:

increase in the quality of ovaries;
increasing the sugar content of fruits without the use of basic dressings;
extending the shelf life of the crop.

We have already found out that boron is necessary for all plants, and figured out what benefits it brings. But the individual need for a trace element varies from culture to culture. Boric acid as a fertilizer should be strictly dosed for the following groups of plants:

Most of all, beets, cabbage and pome fruits need to be fed. fruit trees. All these crops, depending on the type of soil, are fertilized with a solution with a concentration of 1 to 10 g per 10 liters of water.
Most vegetables, herbs, berry bushes and stone fruits moderately need boron. After processing, the yield of these crops will increase slightly, so you can immediately apply, which contains boron.
Fertilizing herbs and legumes with boric acid is extremely rare. This mainly happens before sowing or in the case of severe boron starvation.
Potatoes and strawberries need little boric fertilizer, but with a lack of this trace element, they immediately fall ill. The application of top dressing is carried out before planting. If the petioles of the leaves began to break and turn red in the potatoes, mushroom scab is found, then spraying a 0.9% solution of boric acid will be the salvation. Strawberries are sprayed with a solution of boric acid mixed with manganese and ash extract.

Boric acid for seedlings

Often summer residents feed seedlings with boric acid of crops such as tomatoes, cucumbers and peppers. This is necessary for the full growth of the plant stem, improving the taste of the fruit. Spraying is carried out at the time of the appearance and blooming of the buds. Two recipes of solutions have proven themselves best:

To spray tomatoes, dissolve 10 g of powder in 10 liters of water heated to 75 degrees. Wait for the solution to cool and apply as usual.
Boron-iodine solution is considered more effective. To prepare it, you will need 10 liters of hot water, 5 grams of boric acid and 5 drops of iodine. In addition to the main benefits, this fertilizer warns plants well.

Boric acid - application in the garden

The use of boric acid in the garden is not limited to spraying plants. Experienced gardeners use fertilizer in the following cases:

As seedbed preparation. In this case, 0.01% to 0.1% boric acid solution is used.
As a seed growth stimulant. 20 mg of boron are dissolved in 1 liter of water. Seeds of tomatoes, beets and carrots are soaked for a day in a solution, and cucumbers, zucchini and cabbage for ½ day.
The most popular remedy for chlorosis is boric acid, the use for garden plants in the spray form is carried out both as planned and in case of a detected boron deficiency.

Boric acid in horticulture

In the garden, apple trees, pears and grapes suffer the most from a lack of boron:

In an apple tree with a lack of a microelement, the leaves become thicker and warp. The veins darken. And the fruits begin to suffer "internal corking of apples". Light spots appear in their pulp, which then darken and resemble a sponge. The rind swells and deforms.
In pears, the leaves also thicken and darken. The flowers of the plant dry quickly and the fruits are deformed. The situation will be saved by double spraying with boron solution (10,000 - 20,000 mg per 10 liters of water). The first time top dressing is applied before blooming buds, repeat the procedure after a week.
In grapes, a lack of boron is manifested by progressive chlorosis and peas, that is, small ovaries on the hands. Boric acid in the garden for grapes is used together with zinc. For 10 liters of water, 5 g of boric and zinc sulfate are taken.

Boric acid for indoor flowers

Boric acid for flowers is useful in that it enhances root system and flowering plants. Treatment with a solution (1 g of product per 1 liter of water) is carried out several times per season: before and immediately after flowering, then after 14 days and, possibly, so that the ovary does not fall off. Violets and roses respond positively to boron top dressing. With severe chlorosis - yellowing or whitening of the leaves, dying off of the buds and cessation of root growth, if the leaves thicken and bend easily, the fertilizer is applied once.

How to dilute boric acid for spraying plants?

We figured out the basic rules for the use of summer residents of boric acid. Let's summarize important points solution preparation process:

Boric acid is diluted in a strict proportion indicated on the instructions from the manufacturer.
The water temperature must be at least 70 degrees. In cold water, undissolved particles will remain, burning the leaves and roots.
You need to spray only with a spray gun in the “drizzle” or “wet fog” mode. Droplets of fertilizer on the leaves are undesirable.

In the garden first-aid kit of each summer resident should be inexpensive and effective remedy- boric acid, the use for plants of which is practically unlimited. Subject to the dosage and regimen of fertilizers, your garden and vegetable garden will be pleased with a rich harvest of delicious, sugary fruits, and the front garden will delight the eye with abundant long flowering.

» Tomatoes (tomatoes)

Care cultivated plants in 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, as well as other crops, are very sensitive to fertilizers and respond abundant flowering, increase in ovaries and rich fruiting. One of the unique dressings is boric acid. It not only provides tomatoes with such an indispensable trace element as boron, but also effectively fights late blight of tomatoes when sprayed.

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

Boric acid - crystalline powder white color, having no taste and smell, easily soluble in warm water. Boron is part of many ready-made fertilizers, primarily used for seedlings, as it helps to improve its nutrition, more complete absorption of nutrient organic and mineral substances from the soil, thereby creating a good basis 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 apples in greenhouse and open field.

Boric acid is very effective in the fight against late blight, Besides:

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

For tomatoes, top dressing with boron is especially useful, it is carried out in two ways:

foliar spraying of the ground part tomatoes with a solution of boric acid;
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.

This top dressing is especially useful for tomatoes grown at home - in flower pots or on the balcony, since they are more weakened than ground relatives, require enhanced nutrition.

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

When to feed

For the entire growing season, top dressing 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). Seeds are dipped into the solution in a gauze bag so that they do not float to the surface.

This seed treatment is increases their germination, strengthens seedlings, contributing to a more complete intake of nutrients, protects against diseases even at high humidity.

Subsequent sprays are carried out 3 more times:

during the formation of buds;
during the period of mass flowering;
at the stage of fruiting.

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

The finished solution for spraying (see recipe below) should be sprayed from the spray gun directly on the leaves, stems, buds, flowers and fruits of tomatoes. Such top dressing much more efficient than watering under the root, as it ensures the rapid absorption of boron by the plant. The result is already noticeable literally on the second or third day after treatment.

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

So 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 crop.

Signs of boron deficiency in tomatoes

By appearance Plants are easy to determine that they are deficient in boron:

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

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

Useful properties of boric acid for tomatoes

Tomato is one of the most popular fruits in the garden or garden plot. The benefits of boric acid for their nutrition and cultivation cannot be overestimated. We can say that the future crop of tomatoes largely depends on boric acid, because it positively influences the whole process of vegetation plants:

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

Instructions for preparing a spray solution

To prepare the solution, you must 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 with this ready solution spray tomatoes.

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

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

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

It often happens that cultures stop developing, the leaves become brittle and wrinkled, flowers do not form, and the fruits turn out to be small and deformed. This indicates boron starvation of plants, and in order to cope with this, it is necessary correct application boric acid.

After treatment with boron, the roots of the plant are supplied with oxygen, calcium enters all the fibers of the plant, the volume of chlorophyll increases, and metabolic reactions are accelerated.

Spraying seeds before planting, stimulate their germination.

Plants are able to consume boron only in the form of a solution - boric acid.

After fertilizing tomatoes and crops in the garden, yield increases by 1/3, taste qualities are improved, the shelf life of fruits is extended.

Mechanism of action

The trace element boron, getting into the plant, accelerates biochemical processes, helps to saturate it nutrients. Acid is most often used as a spray, since boron ions in plants tend to migrate very slowly.

Fertilizer is used for many crops:

Potato tubers are processed before planting. It is necessary to secure the culture from scab disease.
Tomatoes are recommended to be sprayed during the period of the appearance of flowers and the formation of buds. Thanks to processing the number of ties will increase, and the sugar content, taste properties will improve, and the size of the fruit will be larger.
Beets can be fertilized to increase yields.
Apple and pear trees are sprayed to increase the yield and reduce the fall of the ovaries.
For strawberries, this fertilizer is necessary for better fruit formation, a set of sugar content, as well as protection against gray rot.
Grapes after spraying will have much more ovaries than without it.
The rose will bloom longer, the buds will become larger, and fungal diseases will not appear.
Gladioli also will not get sick with a fungus, they will increase the number of bulbs.
Dahlias, thanks to boron, will become larger. Therefore, there will be a need for a garter of flowers.

The use of boric acid in the garden and vegetable garden

Fertilizer use on all types of soil and for most horticultural and fruit crops. If you feed them in a timely manner, then fast growth and reinforcement guaranteed.

For complete dissolution, boric acid must be diluted in one liter of hot water. After cooling, bring the solution to the right amount by adding water.

Application for fruit trees

In apple and pear trees there should be high concentration boron. But you can’t oversaturate them, otherwise lower leaves may get burned.

To process trees, you need to breed 15 grams of powder per 10 liters of water. You need to spray the entire crown at sunset twice: during the opening of the buds, then a week later.

Use on vegetables and tomatoes

For tomatoes, it is better to use the solution during the appearance of ovaries and the formation of green fruits. 10 grams of acid diluted with 10 liters of water.

Cucumbers are treated with a solution of 5 grams of boric acid and 2 grams of manganese sulfate per 10 liters of water.

Pepper is fertilized three times during the growth period on moist soil at the rate of 1 gram for 10 liters of water.

Beets are fed in the phase of the appearance of 5-6 leaves, then after 2 weeks. On the 1 gram take 10 liters of water.

Application on beds with berries

Timely fertilization with boric acid improves the growth of berry crops, helps them become strong, increases fruiting, preserves the crop and gives resistance to negative conditions as well as pests and infections.

Before planting strawberries, the material must be kept for 2 days in a solution, for the preparation of which 0.2 grams powder is consumed per 1 liter hot water.

Strawberries are fed 3 times:

In early spring 1 gram of potassium permanganate and 1 gram of boric acid must be diluted in 10 liters of water. Then you need to shed the roots of the plants, it is enough for about 35 bushes.
Before flower formation it is necessary to spray the berry crop. For the preparation of fertilizer, 5 grams of boron powder is taken per 10 liters of water.
During the flowering period, strawberries can be sprayed or shed its root system nutrient solution. For this 1 glass wood ash you need to fill in 2 liters. boiling water, stir and let it brew for 2 hours. Then add 3 grams of potassium permanganate, 3 grams of boric acid, 1 tablespoon of iodine and 8 liters of water there.

To enrich raspberries and strawberries with nutrients in early spring, you can take a bucket of water with a pink solution of potassium permanganate, add boric acid to the tip of a knife, mix everything thoroughly.

Safety measures when working with the tool

It is believed that this fertilizer in a small amount will not harm a person. But while working with him, you need to use special clothing, gloves and a respirator. Upon completion, wash your face and hands thoroughly with soap and water.

Fertilizer can ignite easily, so it is unacceptable to leave it in the fire zone. It is recommended to close the packaging well and use a dark and cool place for storage.

Compatibility with other drugs

Boric acid is compatible with many fertilizers. The main condition, when preparing a solution with other substances, the concentration of the powder must be halve.

First aid for poisoning

Boric acid, getting inside a person, can provoke nausea, vomiting, diarrhea, rash, redness. In case of accidental ingestion of fertilizer into the stomach, you need to drink several glasses of water and induce vomiting.

If she got on open area skin, its necessary wash with soap.

An experienced gardener who timely finds signs of starvation with boron in horticultural crops will definitely feed them with boron. The use of boric acid is beneficial for all plants. Indeed, thanks to its action, the harvest is rich, the taste of the fruit improves, and the shelf life is extended.
