The benefits and harms of boric acid for plants. Boric acid for plants: how to use it correctly, recommendations for gardeners

How, besides epin, zircon, HB-101, you can cheer up your green pets? It turns out that in home arsenal there are a lot of products that can successfully replace newfangled preparations that can not only facilitate plant care, but also completely replace chemical top dressings or growth and flowering stimulants. And they are good not only for indoor, but also for garden plants.

The most elementary , and not t requiring no tricks - hot shower! Hot water (not boiling water, of course) will not only prevent pests, but good stimulant growth.

Before the procedure itself, all indoor plants should be well watered, after 1-2 hours put in the bath and turn on the shower.

Temperature hot water should be such that the hand endures. Water the plants with a hot stream for one to two minutes. Hot water that has fallen into the pot will help in the fight against soil pests (if they are wound up). After showering, plants should be left in the tub overnight to dry out excess water from glass pots. Hot showers can be done by almost everyone indoor flowers except Saintpaulia. Such procedures begin to be done in February and continue throughout the season. The results will not be long in coming, they can be seen in a week.

Sugar. For top dressing, it is enough to pour one teaspoon of granulated sugar on the surface of the soil in a pot before watering, or water it with sweet water once a week. Two teaspoons of granulated sugar are taken for one glass of water. Cacti adore top dressing with granulated sugar.

Castor oil. Castor oil top dressings are good for stimulating flowering and fruit formation. One teaspoon of castor oil is enough for one liter of water. Shake the solution well before use.

Common Zelenka (brilliant green solution), as well as fucorcin(red liquid), which have a powerful antifungal effect, will help in the fight against fungal diseases. Bulbs of hyacinths, lilies, tulips and other bulbous and bulbous plants in places of damage, as well as scratches and damage to the stems of roses, especially after winter, can be smeared with brilliant green or fucorcin. Scratches and damage, heal and do not rot.

Boric acid . A solution of boric acid is also a stimulant for the formation of buds, ovaries. Boric acid can easily replace the well-known "Ovary" in the garden to stimulate flowering and fruit formation in vegetable crops, for example, in tomatoes, cucumbers, as well as during the formation of heads on cabbage, and even all fruit bushes and trees. Working solution - dilute a sachet of boric acid in two liters of water. Spray the plants with this solution several times per season: before flowering, immediately after flowering, two weeks after flowering, so that the ovary does not fall off.

An effective stimulator of growth and root formation is considered aloe juice. It is good for soaking or germinating seeds.

Succinic acid. Seller in flower shop once he persuaded me to buy succinic acid: they say that this remedy surprisingly stimulates the growth of plants and it is impossible to overdo it.
At home, I diluted 1 g of powder into 5 liters. water, watered and sprayed with a solution of all house plants.

The result was awesome! And it became noticeable after a week:

Marantaceae have released new leaves and shoots.
- I liked the top dressing and begonias: ever-flowering, for example, immediately gave 4 powerful side shoots, flowering intensified.
- The pandanus has new leaves not only at the top, but also from under the leaves of the first, second and third row.
- Aglaonems have released new leaves, some have given babies.
- A good increase in leaves was given by mandarin cuttings, ficuses, chlorophytums, peperomia, alocasia, syngoniums, oleanders.
- prickly pear
At first she was covered with thorns, and then she released 12 lateral segments.
- A stalk of African purslane that has not rooted for a long time has released 2 lateral shoots.
- The Decembrist, agave, Aih-rizon liked the “treat”, the growth of leaves in fat women and crossworts noticeably quickened.

Separately, I want to talk about the use of succinic acid for cacti and succulents. I did not expect rapid growth from them, but I was very surprised when a month later Havortia released 10 children at once.
- The cacti were also happy.

However, I do not advise you to reapply succinic acid to cacti and succulents: a reverse reaction may occur.
Fertilizer should be applied once or repeated no more than once every 2 years.

Properties of succinic acid for plants
Due to the excellent natural utilization of succinic acid in nature, it does not pollute environment. Therefore (and not only) it is often used for plants.
It is an excellent plant growth regulator, improves the absorption of substances from the soil, and also helps plants cope with various kinds of stress.
Succinic acid normalizes the natural microflora of the soil, the vital activity of microorganisms in it.
Treatment of plants with acid increases resistance to adverse environmental influences.
Its use in relation to certain parts of plants, respectively, stimulates growth: root treatment - the growth of roots, young shoots - the growth of new shoots.
Succinic acid is an excellent resuscitator for plants.
It is treated with seeds and cuttings before planting. various plants to improve germination and stability.

Dosage of succinic acid
To prepare working solutions suitable for spraying and soaking, 1 g of succinic acid must be dissolved in a small amount warm water. We make a strong solution of succinic acid. The volume of the solution after that cold water bring up to 1 liter. That is, it turned out to be a solution of 1 g per 1 liter - a one percent solution.
Further, to obtain a 0.02% solution of succinic acid, dilute 200 ml of 1% cold water to 1 liter.
To obtain a 0.05% solution - 500 ml of a strong solution is brought to a liter with cold water.

Honey, to be exact. honey solution , is also a powerful biostimulant. It can be successfully used for soaking and germinating seeds, rooting cuttings. Honey solution can be used in the garden during flowering for better pollination and ovary formation.

Honey solution is good to use in bucket traps hung on fruit trees, for the preservation of fruits from pests.

fresh apples. One kilogram of chopped apples insist in five liters of water for two days, and top dressing for all plants is ready. An infusion of fresh apples is especially adored by such plants as Schlumbergera, Zygocactus, Ripsalidopsis.

Milk. For variegated and ornamental leafy plants, regular milk can be used as a top dressing. Working solution: 100 ml of milk is diluted in one liter of water. Such watering is very fond of ferns. Watering with milk water is alternated after 2-3 waterings with plain water.

B vitamins (B 1, B 6, B 12), as well as vitamin C can be used for rooting cuttings, soaking seeds, developing the root system. For a working solution, just a few drops per liter of water are enough.

yeast solution can with great success replace such a root stimulator as heteroauxin. Preparation of a working solution: 100 mg of yeast must be dissolved in one liter of water. In this solution for a day, place the cuttings prepared for rooting. After that, the cuttings must be removed from the yeast solution, rinsed with water and placed for rooting in a mini-greenhouse or a container of water. If you put the cutting into the water to take root, then do not forget to put it there small piece charcoal.

Yeast solution can also be used in the garden. In the spring, when planting, they can water all plants, including roses.

Decoction onion peel is perceived by all plants without exception as a complete fertilizer. With a decoction, you can not only water the ground, but also sprinkle the entire plant for prevention from pests. A decoction of onion peel (it is prepared as for coloring Easter eggs) will scare away aphids, and the infusion (200 g of husk per 10 liters of water) will help save cucumbers from spider mite. Preparation of a decoction of onion peel for feeding plants: pour one or two handfuls of onion peel with one liter of boiling water, boil for 3-5 minutes, let cool. After that, strain the broth and you can use it! It is advisable to use all the cooked decoction of onion peel at a time.

Dried sleeping tea very useful for large varieties tomatoes. Start harvesting used tea leaves now. When planting tomatoes in the prepared ground, throw a handful of sleeping tea. This tool will not only improve the soil, but also serve as a source essential trace elements for large tomatoes. A healthy plant, as we know, is less affected by diseases and pests.

Excellent fertilizer for indoor plants - aquarium water. There are many substances in aquarium water that stimulate plant growth. It is recommended to use aquarium water as top dressing only in spring and early summer, when active growth new shoots and leaves. In the second half of summer, when young shoots and seeds are already ripening, as well as for feeding slowly growing cacti and succulents aquarium water better not to use.

Potato broth can also be used as a top dressing for all plants. Cool the water in which the potatoes were boiled, strain and then dilute it strongly. I tested, it works! Of course, at first I was very afraid, I thought that suddenly the earth in the pots would immediately turn sour, then, nevertheless, I took a chance. Satisfied with the result.

Water used to wash raw meat , can be used as a top dressing for all plants. To feed indoor plants, it is recommended to insist this water for two weeks so that it ferments and becomes suitable for irrigation. I watered the plants in the garden with such water without insisting. Dahlias, which often got water after washing their meat, bloomed much earlier than the others, the bushes were gorgeous, and the buds were dark. So that's checked too.

Decoctions and infusions from other plants are the best suited not only for feeding, but also help to cope with pests.

Infusion of wormwood increases the immunity of plants, helps to cope with rust on the leaves of pelargonium, stock roses, lavaters, roses, and is also used in the fight against aphids, various caterpillars and other leaf-eating insects. Preparation of working solution: wormwood can be used in dry and fresh, pour cold water and let stand for 1-3 days. Used without dilution. This infusion is very effective in the spring.

You can hold the infusion of wormwood for two weeks, let it wander. Such an infusion is recommended to be diluted ten times. It can be used for watering and spraying indoor and garden plants.

As has long been observed, some garden plants possess not only healing power, but also restrain the onslaught of pests. For example, gypsophila and l avant prevent the attack of aphids and ants on neighboring plants, marigold and calendula protect neighboring plants from nematodes and other underground pests, garlic kills fungal and viral diseases, including powdery mildew. Therefore, infusions and decoctions of these plants have exactly the same power and can be used with great success as biological pest and disease control agents.

Nettle infusion increases the immunity of plants and is also used as a complete top dressing for all plants. Nettle infusion is prepared according to the same principle as wormwood infusion. You can insist nettles in water for a day or three and water the plants with this infusion, or you can wait until fermentation begins. In order not to stink so much, you can add a little borax to this infusion. After fermentation, strain the nettle infusion, dilute with water at a concentration of 1:10. Such herbal infusions are good to do outdoors in summer. And the herbs are in abundance, and the house does not smell. To combat aphids, you can spray the plants with undiluted nettle infusion.

Nettle infusion is a natural and versatile complex with micro- and macroelements, which surpasses all chemical growth stimulants in its effect on plants.

Infusion comfrey can be used as top dressing in the second half of summer, when plants need a lot of potassium to prepare for winter.

Making an infusion of comfrey is similar to making an infusion of wormwood or nettle. Comfrey infusion can be used for all plants, but it is especially useful for plants that need a lot of potassium and a little nitrogen for full development. Spraying with comfrey infusion over the leaves very quickly removes the signs of potassium starvation. In the infusion of comfrey, the main nutrients - nitrogen, phosphorus and potassium are in such a proportion of 3:1:7.

A decoction of horsetail will help not only strengthen plant tissues, help to cope with rust on the leaves, powdery mildew, spider mites. Horsetail can be used both fresh and dry. Preparation of the working solution: Pour the grass with cold water and leave for a day. After that, boil the infusion with horsetail, let it cool, strain into a glass or plastic bowl. A decoction of horsetail can be sprayed on both indoor and garden plants. A decoction of horsetail can be added to water for irrigation. Against the spider mite, for a lasting effect, it is necessary to carry out repeated sprayings with a decoction of horsetail.

Valerian juice. Grind fresh valerian herb, add a little boiled or rain water, squeeze. The resulting valerian extract, pour into a glass container and store in the refrigerator. The container with valerian extract must be shaken well before use. It is enough to add only 30 drops of such an extract to a bucket of water. It is recommended to water and spray all plants, including orchids. I myself have not experienced it yet, but they say that this is truly a "magic remedy". Why not HB-101, which is sold for big money?

Such extracts, infusions, decoctions can be made from almost any plant and in any combination.

To make the plants bloom even more beautifully, during the budding period
fertilizer needs to be applied.
I am my flowers when they begin to form buds,
I water it with castor oil.
From this plant bloom more magnificently and longer,
and flower heads get bigger
and richer color.
Here's what you need to do.

Fill a liter plastic bottle
settled water room temperature
and add 1 tsp of castor oil to it.
Then screw the cap on tightly.
and shake the contents thoroughly.
Castor oil should be broken down into tiny fractions
and mix with water. If castor oil is not stirred well,
then it can burn the roots of the plant.
Be sure to check what happened.
Then immediately, until the castor oil has risen
water surface, water the flowers.
If they bloom once a year, then one such top dressing is enough.
If the plants bloom constantly,
then you need to feed them with castor oil once a month.

Boric acid is a microfertilizer for plant nutrition during the growing season. Timely top dressing can give rapid growth of young shoots. It improves the nutrition of the ovaries and increases their number. In addition, boron is able to protect plants from many diseases.

Plant diseases caused by boron deficiency:
. heart rot in root crops;
. heart rot in beets;
. hollow stem of cauliflower;
. hollowness of root crops;
. brown rot in cauliflower;
. scab on root crops;
. fruit pulp necrosis.

Application of boric acid:

Plants need to be sprayed regularly. Before flowering, during flowering and during fruiting, when the fruits reach normal sizes. The optimal dosage is 20 g of fertilizer per 10 liters of water. It is this ratio that brings the best result.

Seed germination will improve if treated before sowing. It is enough to soak the seeds in this solution for 12 hours. Seeds of carrots, onions or beets are soaked for a day. The seeds are then dried and sown.

Boric acid solves many problems of fruit plants. Protects against diseases, increases yield by 20-25% and increases sugar content. This makes the fruits tastier and sweeter. In addition, processed berries will not rot or crack from excessive moisture.

Fertilizers must be applied when the fruits have reached their norm, so that microelements can only affect the composition of the pulp.

Presowing seed treatment with boric acid:

Soaking seeds in a solution of boric acid, prepared at the rate of 0.2 g of the drug per 1 liter of water (or -2 grams of boric acid per 10 liters of water.) - renders positive influence for seed germination. Can be used together with other trace elements. Seeds of carrots, tomatoes, onions, beets are soaked for 1 day, cabbage, cucumbers, zucchini for 12 hours.

Pre-sowing treatment of seeds with a complex of microelements:

Mix 1 liter of water, 0.1-0.3 g of boric acid, 0.5-1 g of potassium permanganate, 0.5-1 g of ammonium molybdate, 0.3-0.5 g of methylene blue, 0.1-0 .5 g blue vitriol, 0.2-0.5 g of zinc sulfate. The solution should be prepared as much as is needed to completely submerge the treated seeds. After processing, they are dried and sown.

Main entry:

They are applied to the soil before sowing seeds or planting vegetable seedlings, fruit crops and flowers at the rate of 2 g of fertilizer (previously diluted in 10 liters of water) per 10 m2, followed by loosening.

Top dressing:

It is carried out with a solution prepared at the rate of 5 grams of boric acid per 10 liters of water (or 1 gram per liter). Moreover, first dissolve the drug in a small amount of hot water, then add required amount cold water up to the norm. The first spraying is carried out in the budding phase, the second - in the flowering phase, the third - during the fruiting period. Boric acid treatment of fruit and berry crops gives an increase in yield by an average of 20-25%. When combined with other trace elements, the concentration of boric acid is reduced to 0.05-0.06%, i.e. 0.5-0.6 g / l is used.

In addition to boric acid, granular boron superphosphate (18.5-19.3% phosphorus and 1% boric acid) or double boron superphosphate (40-42% phosphorus and 1.5% boric acid) are used for plant nutrition.

For feeding berries:

Some gardeners add boric acid to a bucket of water with a pink solution of potassium permanganate at the tip of a knife, mix everything thoroughly and use it to feed strawberries and raspberries in early spring.

Such top dressing not only helps to increase the yield, it also improves the taste of the berries.

In addition to the above, boric acid is used as a component of a complex nutrient solution for soaking seeds before planting: two handfuls of onion peel are poured with a liter of boiling water and mixed with a pre-prepared ash solution in a 1: 1 ratio. For 1 liter of such a solution, add 1 gram of manganese, 0.1-0.3 grams of boric acid and 5 grams of baking soda.

Insect control:

Boric acid is also effective in the fight against insects. With its help, you can get rid of cockroaches and ants. When there was nothing in stores other than dichlorvos, many housewives used boric acid. It was much more efficient and convenient. There was no unpleasant smell, and besides, boric acid is completely harmless to both people and pets.

How to deal with ants:

Why is it so difficult to get rid of ants, because they are very sensitive to poisons? The poison only kills worker ants that are outside the nest. And this loss is quickly replenished, and the number of ants increases again and again.

However, using a simple bait using boric acid can destroy the entire colony. The poison acts slowly, and the ants have time to convey the poisonous substance to other ants.

The bait is very easy to make. 4 teaspoons of sugar are added to one glass of boric acid solution. Pieces of cotton wool or tampons are moistened with a solution and left near the anthill. Periodically changing the moistened pieces, you need to wait until the ants disappear.

" Strawberry

Timely and proper nutrition- pledge good harvest strawberries. She should receive fertilizer at least three times a year: in spring, at the beginning of the growing season, in summer, during flowering and in autumn, before preparing for winter. But, for some reason, most gardeners ignore this milestone top dressing during the flowering period of strawberries - after all, it is then that she needs additional strength. In this review, we will consider how to feed strawberries during flowering with boric acid and iodine.

Nutrients Needed by Strawberries all year round. This is especially true when it is grown in the same place for many years in a row. Additional feeding is especially important during the flowering period, since the entire crop depends on how the ovaries and inflorescences are formed.

The main purpose of feeding is to restore balance nutrients in the soil. Choice the right fertilizer depends on many factors such as:

Soil composition.
Weather.
plant condition.
Plant age.

During the flowering period, strawberries are actively developing and require special attention, care and concern. Exists a large number of special mineral fertilizers, but folk remedies for fertilizer, such as ash, boric acid, manure, herbal infusions, iodine, chicken droppings, are still popular.

Agrochemicals should not be used during flowering, as they can accumulate in berries and subsequently cause poisoning in humans.

Agrochemicals are fertilizers of chemical or biological origin that are used to nourish plants, soil, and also to control pests. Their improper use in excess dosages can cause more harm than good.

During the flowering period, strawberries are best fertilized with organic matter in the root or root method. Root top dressing- the solution is applied to the soil, and foliar - the bushes are irrigated from above with nutrient compounds.

Top dressing during flowering should be done only with one type of fertilizer and once.

Apply all fertilizers only in a diluted form and strictly adhering to the proportions. With all the safety of the funds, you should try not to fall on the flowers and berries as much as possible - spray only the stems and leaves, the lower ones are best. Fertilizers should be applied to moist soil - the next day after heavy rain or watering and during daylight hours.

If strawberries are fed during flowering, then big harvest large and tasty berries are guaranteed, because it is during this period that the greatest susceptibility to fertilizer is.

Boric acid for feeding strawberries during flowering in spring

Feeding strawberries with boric acid during flowering improves the nutrition of the ovaries and increases the plant's resistance to adverse weather conditions, as for potatoes and tomatoes. The fruits become sweeter and denser, so that they do not crack from moisture. Boric acid works best as a fertilizer on soddy-podzolic and peaty soils.

Boric acid is an antiseptic that is sold in a pharmacy and has a release form: solution or powder. Usually, recipes indicate the dosage of boric acid in grams, and if you use an alcohol solution, then you need to determine how many milliliters of the solution are 1 gram of boric acid. There is no standard, since solutions are produced with different boron content. If powder is used in gardening, then it must first be dissolved in a small amount of hot water.

Boric acid has no color, no taste, no smell - this is its danger, because it refers to poisons and its overdose can only be determined by the negative consequences.

Strawberry - perennial, requiring bright sun, rich and moist soil, in which mold and fungi often start. They negatively affect the taste and quality of the fruit, and in order to prevent this, it is necessary to treat its bushes with a solution of boric acid.

Signs of a Boron Deficiency

Strawberries are treated with boric acid even when it lacks boron - an important trace element required for normal plant life. This is expressed in the fact that:

Leaves dry along the edges.
The plant becomes lethargic even with good watering.
The leaves are deformed and crumble.

To feed strawberries, take 1 g of boric acid and 1 g of potassium permanganate per 10 liters of water. Plants should be watered with this solution only at the beginning of flowering, or after the plant has ceased to bear fruit.

Fertilizer Recipe

Also effective recipe such a root dressing: 2 grams of boric acid, 2 grams of potassium permanganate and 1 cup of ash are dissolved in 10 liters of water - it has double effect, since ash is an organic potassium phosphate fertilizer.

Use water that is not chlorinated, but purified by boiling or a filter, and it is also necessary to carefully adhere to the dosages so as not to harm the plant.

Boric acid as a fertilizer contributes to the supply of oxygen to the roots, it improves metabolic processes and improves the quality of potassium penetration from the soil into all plant fibers, which affects the shelf life of fruits.

To prepare a solution for irrigation you need to take 1 sachet of pharmacy boric acid (10 grams) and dilute it in 30 liters of water. It is necessary to process with this solution according to the already known rule - on the lower leaves.

Iodine - an indispensable tool for the care of strawberries, recipes and recommendations

Iodine is a well-known antiseptic, which is usually used for domestic purposes: disinfection of wounds and cuts. But it turns out that its use in the garden can protect against many diseases, such as the appearance of late blight, rot, powdery mildew and not only.

To get a good harvest of strawberries, iodine must be used as a fertilizer, because thanks to this:

increases plant immunity they become more disease resistant
happens more efficiently budding process;
increases number of ovaries;
improved security and fruit keeping quality;
productivity increases, and the fruits become large and tasty.

Solution preparation, proportions

Iodine is a trace element that is found in many microorganisms and its presence in strawberry bites depends on whether it is present in the soil and groundwater if not - you need top dressing. Its lack is determined by such external signs - delayed fruiting, rotting of the ovaries, the appearance of powdery mildew, gray rot.

The safe limit of iodine concentration in a plant is 0.1 mg per 1 liter of water - in terms of this, this is 20 drops for root dressing and 10 drops for spraying.

For root fertilizer it is better to do warm solutions and to increase efficiency, add wood ash. Such an enriched liquid should be poured 500 ml under one bush to get the desired result.

For the yield and quality of fruits, it is necessary to treat plants with iodine during the flowering period. It is best to carry out this procedure in cloudy weather, or at night, as iodine is in duet with bright sun able to burn the leaves.

For root fertilizer, you can use the following solution: 1 glass wood ash pour 2 cups boiling water - leave for 2 hours. Add to this tincture 2 grams of potassium permanganate (not a solution, but crystals), 3 grams of boric acid, 10 drops of iodine and pour 10 liters of warm settled (necessarily dechlorinated) water. The principle of the fertilization process: 1 250 ml glass under one bush.

The only drawback of pharmaceutical iodine is that it is practically unable to enrich the soil. That is, they can only fertilize strawberries, and to enrich the soil it is better to use mineral fertilizers with iodine, but not during flowering, but in spring.

Strawberries must be fertilized during flowering and this should be done only with organic and proven means. Iodine and boric acid are safe and effective means - the main thing is to adhere to the dosages and recommendations for use, and then the strawberries will delight you with a rich harvest of tasty and sweet berries.

Foliar top dressing of beets with boric acid

BO3H3 - easily digestible by plants chemical compound boron, known as boric acid, is widely and successfully used in garden plots. It is an odorless white powder and is sold separately or in complex top dressing at any gardening store.

The use of boric acid in the garden

The impact that boric acid has in the garden is not exaggerated. It has been experimentally proven that due to the introduction into the soil:

the number of fruit set increases;
the emergence and growth of young shoots is accelerated;
the amount of sugar in ripe fruits increases.

The use of boric acid in the garden improves the absorption of nitrogen, which increases the yield and resistance of crops to frost and drought by 25%.

Boric acid in the garden is applied throughout the entire vegetative process, as it is not transmitted from the grown stems to the young and constantly requires renewal. Plants on marshy soils are especially in need of boron, with high content carbonates. Also, the element is necessary in soil with high acidity after it has been deoxidized with lime or other alkali-containing substances.

Be careful with boric acid!

The use of boric acid in the garden is safe in strictly specified proportions, but with its excess in the soil, the plants experience a burn of the lower leaf plates, the edges of which turn yellow and die.

Boric acid for the garden - methods of application

Boron must be dissolved in hot water. After the solution is diluted with cold water to the desired amount.

The element is used not only as a fertilizer, but also as a stimulant. To accelerate growth, the seeds are soaked in 0.2 g of boron, diluted in 1 liter of water. Seeds of tomatoes, beets, onions and carrots are left for 24 hours, cucumbers, cabbage, zucchini - for 12 hours. If there are a lot of seeds, then they are sprinkled with boron and talc (1: 1).

For the prevention of boron deficiency in the soil when seedbed preparation, the beds are watered with boron solution (1 liter per 1 sq.m.), loosen and start sowing.

For spraying on summer period use a sprayer that forms a foggy cloud. foliar top dressing carried out on both sides of the sheet only in the evening or in cloudy weather. For best result add 1-2 grams of manganese.

Root top dressing with boron is carried out only if necessary!

Root watering (on average - 0.2 g of boron per 1 liter of water) is carried out only with a clear boron deficiency. Before irrigation with bromine, the plant is watered to avoid root burn. This procedure is effective on sod-podzolic soils or sandy-peat soil.

Fertilizing vegetables with boric acid

On various horticultural crops the deficiency of one or another element manifests itself in different ways. For each plant grown in certain conditions it is necessary to observe a strict dosage so as not to destroy the plant. For top dressing with boron, in the presence of signs of shortage, watering with a solution is used, and for prevention, only spraying.

Feeding tomatoes with boric acid

The lack of boron in a tomato is expressed in the following signs:

oppressed black points of growth;
brittle young stems;
brown spots on tomatoes.

Foliar top dressing of tomatoes with boric acid (10 g of boron per 10 l of water) is carried out during the ovary and at the stage of formed green fruits to improve taste and stimulate rapid growth.

Top dressing of tomatoes with boric acid can be carried out at the fourth leaf stage with a mixture of 0.5 g of boron, 10 g of superphosphate and 8 g of potassium chloride per 10 liters of water. On average, this amount of the mixture is enough for 200 bushes.

Processing tomatoes with boric acid and iodine is suitable for protection against late blight from June 15. Dry leaves are sprayed with a weak solution of potassium permanganate; after 7 days - with a boron solution (1 g per 10 liters of water), and after another week - with a weak 1% solution of iodine.

Preventive treatment of tomatoes with boric acid in the greenhouse is carried out once a month by spraying with boric acid. Take 2 g per 10-liter bucket. Boric acid can be replaced with Borax. If signs of a lack of boron are found, the treatment is carried out with a more concentrated solution - 10 g of boron per 10 liters of water.

Feeding cucumbers with boric acid

Boron deficiency in cucumbers can be recognized by the following signs:

yellow edge on the sheet plate;
longitudinal yellow stripes on ripe fruits;
cessation of growth;
tie death.

Foliar top dressing of cucumbers with boric acid is carried out three times during the growing season complex fertilizers: Kelkat Bora, Bor-Mag, Green Belt - according to the instructions.

Spraying with a mixture of 5 g of boric acid and 2 g of manganese sulfate on open field at intervals of 14 days prevents the fall of the ovaries, and increases the yield. In greenhouses, such treatment of cucumbers with boric acid is carried out twice a month.

To increase the fruiting time at the flowering stage, cucumbers are sprayed with a mixture of 0.5% potassium chloride, 5% superphosphate, 0.1% magnesium sulfate and 0.03% boron in equal proportions.

Boric acid for cabbage - application

Boron deficiency in cabbage is manifested in the formation of a hollow head. In color, you can observe such signs as:

vitreousness - transparency of inflorescences;
deformation of the heads;
rusty inflorescences;
bitter taste.

Fertilizing cabbage with boric acid with manganese sulfate is carried out three times: during the formation of buds, during flowering (if there are 5 leaves) and fruiting (10 g of manganese sulfate and 1 g of boric acid per 1 liter of water). Boron makes the head more dense and increases the yield.

Top dressing of cauliflower with boric acid and molybdenum (2.5 g per 1 liter of water) is carried out at the 4-leaf phase to accelerate the maturation of the heads for a week.

Boric acid for peppers - application

The lack of boron in pepper manifests itself in the following signs:

small deformed leaves;
cessation of growth of shoots and roots;
falling flowers and ovaries.

Pepper fertilizer with boric acid is carried out three times during the growing season and only on moist soil in the proportion of 0.1 g per 1 liter of water.

Top dressing of beets with boron

Boron deficiency in sugar beet is expressed in the development of apical ulcer and heart rot ( gray rot inside the fetus). At the dining room - internal wormholes with the smell of decay.

Top dressing of beets with boric acid is carried out 2 weeks after the first fertilization at the stage of 5 leaves with a solution of 1 g per 10 liters of water. To strengthen the leaf plate, spray it with a mixture of 15 g of potassium chloride, 5 g of boric acid and 1 tbsp. l urea (urea).

Outcome

Proper use of boric acid in the garden will speed up the ripening of fruits, improve their taste and protect against diseases. Having determined the lack of boron from the photo and description of external signs on plants, you will be able to start fertilizing in a timely manner and save the crop from death.

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 leaf plate and lead to drying. 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 a general gradual wilting of the vine.
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.
