Application of boric acid for garden or garden. Spraying and top dressing of plants with boric acid
For the normal development of plants, a number ofuseful substances and microelements. One of the most important is boron. It promotes the synthesis of nitrogenous components and positively affects metabolism, increasing the amount of chlorophyll in the foliage. Experts believe that the most accessible and simple compounds of this trace element include boric acid. It is successfully used in complex fertilizers.
The active use of boric acid for garden or garden has many beneficial consequences.
What is this tool? These are colorless, odorless crystals that dissolve rapidly in an aqueous medium.
This tool can be used on varioussoils. Good results after application give gray and brown forest, sod-podzolic soils. Gardeners are also advised to bring this substance to light soils, to chernozem. Required application of boric acid for garden or garden on acid soils, boggy or dark-colored.
This tool helps to increase the number ofovaries, significantly increases yield. After the application of boric acid for the garden or garden actively develops the root system and the stem of the plant. Increases the amount of sugar, improves the taste of fruit.
Boron is a "fixed" element in plants. He can not go from old withering leaves to young ones. Therefore, it is necessary for plants throughout the growing season.
Experts know that all garden crops in different quantities need boron. All of them we will conditionally divide into 3 groups of need:
- small (strawberries, potatoes, beans);
- average (tomatoes, carrots, stone fruits);
- high (fruit trees, beets, cabbage, rutabaga).
Although potatoes and strawberries are referred to a group with a low requirement of this trace element, its deficiency can negatively affect these cultures.
Signs of lack of boron in plants
In supplementary feeding, boron need not onlyacid 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 microelement is not enough, then the potatoes begin to turn yellow, the tubers do not develop, and cracks appear on their surface.
The lack of boron in plants can lead to the development of diseases - brown and dry rot, baketriosis, bulging. The shortage in the soil of this microelement is indicated by such signs:
- the buds wither;
- the stems of plants become curved;
- the points of growth die off;
- leaves of plants become curly, pale;
- there is no flowering.
These signs are especially evident inarid seasons. Many amateur gardeners, harvesting a small crop, are blamed for all 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 use of boric acid is invaluable and quiteis diverse. But one should be careful with this element, because an overabundance can damage a plant, accumulating in fruits, like other fertilizers. Therefore, before you get a positive effect from the use of boric acid for a garden or garden, you should pay attention to the advice of experienced gardeners. The main task is to observe the dosage and apply the drug correctly.
Let's consider such ways of using boric acid:
- stimulation of germination of seeds;
- preparing the soil for planting;
- foliar planting;
- top dressing.
To stimulate the germination of seeds activelyboric acid is used. How to breed this remedy correctly? It is necessary for 1 liter of water to take 0.2 g of powdered product. The crystals dissolve rapidly. In this solution, soak the seeds:
- onions, carrots, beets - for 24 hours;
- cucumbers, cabbage, zucchini - for 12 hours.
How to plant boric acid to prepare the soil for planting or planting? All the same: in proportion to 1 liter of water - 0.2 g of funds. This solution should sow the planting beds. Consumption: 10 l per 10 m2. Then the soil should be loosened and after planting the seeds. This method is used when there is a suspicion of a lack of soil in this trace element.
Foliar supplementation with boric acid is very important. Concentration of the solution: per 1 liter of water - 0.1 g of boric acid. The first spraying is carried out at the bud formation stage, the second one at the flowering stage, the third at the fruiting stage. Sometimes other drugs with boric acid are shared. For spraying in this case, take a smaller dose (5-6 g per 10 liters of water).
Foliar supplementation with boric acid is necessaryconduct in cloudy weather. Experienced gardeners always postpone this procedure for the evening, in order to avoid sunburn. If it is necessary to spray on hot days, you should first water the plant.
Topping with boric acid under the root is usedRarely enough. In this case, you should make sure that the soil does not really have enough of this element. Most often this procedure is used for seedling of flower plants that 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 liter of water. But first, the plant is abundantly watered with plain water to avoid chemical burns.
Remember that boric acid dissolves well inhot water. First of all, you need to dissolve 1 packet of the drug in 1 liter of hot water. After this, the solution should be brought to the required volume, mixing with water at room temperature.
Processing of potatoes
The following factors indicate the lack of boron in potatoes:
- general developmental delay;
- disease of mushroom scab;
- the point of growth is oppressed;
- yellow leaves turn yellow;
- blush cherry, become brittle.
The need for potatoes in boron depends directly on thesoil, or rather, its acidity. Also on this indicator affects the temperature and the ratio of minerals contained in the soil. If an amateur summer resident has exceeded the norm during the introduction of nitrogen and potassium, then the plant's need for boron significantly increases. If the dose of phosphorus fertilizer has been increased, the demand decreases.
If the first signs of potatoesdamage to the scab, you need to use boric acid with the calculation of 6 g per 10 liters of water. To prevent this disease, it is necessary to spray the potato tubers at the stage of the appearance of the first shoots.
The lack of boron from beets provokesoccurrence of wormhole and core rot. Often the cause of such lesions is fungal disease - phomosis. In this case, concentric light-brown spots appear on the leaves, in the center of which black dots are located. After the disease goes to the root. At the initial stage, the roots of the root tissue are dark brown in color. Later the affected parts dry up and become rotten.
Before planting, soak in a solution of boric acid seeds. It is also necessary to introduce this microelement into the soil, this prevents the appearance and development of phomosis.
If the soil and seeds are properly prepared, in order to get a good harvest, beetroot is sprayed with boric acid on stage 4 of the leaves. As practice shows, the result will be excellent.
The lack of boron in tomatoes also causesvarious 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. On the fruits appear brown spots, the flesh becomes dry. Some summer residents use a solution of boric acid from phytophthora.
For prevention before planting seedsnecessarily soak in a solution. Before planting in the soil, this solution is also introduced. Take care of the foliar top dressing before flowering. The boric acid on the ovary is positive.
To accelerate the ripening and accumulation of sugar, you can re-spray the boric acid in the green fruit stage.
Boric acid for cucumbers is also actively used. This element helps the plant in the process of flowering and ovary.
During the flowering period, experts recommendTo spend foliar dressing a solution: 5 g of a powder on 10 l of water. Sometimes in a solution of boric acid for cucumbers add sugar, this contributes to better pollination.
To improve the ovary, prevent decay of zucchini and zucchini also use a solution: 2 g of the drug per 10 liters of water. They spray the plants.
Use the same solution of boric acid for pepper and eggplant.
Processing pears and apple trees
Signs of a lack of boron from a pear and apple:
- thickening of leaves;
- darkening and cuffing of veins;
- The leaves fall and fall;
- Small leaves at the ends of the shoots are assembled in the form of a rosette;
- the top of the tree dies.
These signs contribute to the rapid drying of flowers, deformation of the fruit on which traces of affected tissues appear.
In the pulp of apples appear light spots, which gradually become brown and turn into a sponge.
To resume the lack of boron will help foliar top dressing (10-20 g per 10 liters of water). Sprinkle evenly the whole crown. The first time - during the blossoming buds, the second - a week.
Processing of grapes
The lack of boron is indicated by chloroticstains between veins on the leaf, lack of good ovaries. On soils with a minimum amount of this microelement, new seedlings die within 1.5 years.
Experts recommend to process grapes at least once during the formation of buds. It is desirable to add zinc salts to the solution, which also have a positive effect on the quality of the crop.
With a lack of this element strawberry leavesbecome dry. To improve the quality of the crop in early spring, you should pour on the planting solution of boric acid and potassium permanganate (per 10 l of water, 1 g of each drug).
Before flowering, it is also advisable to make foliar dressing with a solution: 2 g of boron, 2 g of manganese and 1 glass of sifted ashes per 10 liters of water.
Processing of ornamental plants
This micronutrient promotes rapidthe absorption of calcium and abundant bud formation. Therefore, experienced gardeners, actively use this tool to get a beautiful, flowering garden. During the formation of buds and flowering, foliar treatment is carried out (10 liters of water per 10 g of the preparation).
Cuttings of roses are immersed not for a few minutes in a solution of boron for the prevention of fungal diseases.
Overdose of the drug
Boric acid is referred to the lowest, 4th,hazard class of harmful substances. If it gets on the skin, this drug does not harm the health of the person. The danger is that this element accumulates in the body, because it is slowly excreted by the kidneys.
Boron can be a panacea, and can be a poison forplants. After all, an overabundance of this drug provokes a burn of leaves. They dry out, die and fall off. Symptoms of overabundance of boron in the soil are yellowing of leaves, folding of their edges. Often the leaves become circular in shape.
The high content of this substance in fodder plants provokes the development of serious diseases in animals.
Fight against insects
Boric acid is not only a useful remedyfor plants. This drug can fight harmful insects. Frequently use dry mixtures with boric acid from ants in the garden. In the body of insects this element accumulates and negatively affects their vital activity, which in the future leads to a fatal outcome.
Boron acts on the nervous system of the ant, causingparalysis and further death. When eating the corpses of their fellow humans, other ants also perish. Therefore, to get rid of ants in the garden, boric acid is needed very little.
In order to remove these insects completely, it is necessary to use this mixture within 1 month.
The recipe for bait from ants
There are many recipes using this drug that help get rid of insects. We will consider the most popular:
- Cook 2 eggs for 30 minutes. Get the yolks and grind them with the addition of 0.5 teaspoon boric acid powder. Spread the resulting balls near an anthill or on an ants path.
- 5 g of the above preparation is dissolved in 100 mlhot water. Add 10 g of honey, 40 g of sugar. All stir and pour into a jar. Cover with a lid to allow for small passages. Put the dishes near the anthill.
- 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 an anthill.
