If we talk about tomatoes, they are recommended to be treated with a solution of boric acid several times during the growth and flowering period in order to increase productivity and carry out simple prevention of diseases, reproduction of harmful insects.
The unique and most important quality of boron for horticultural crops lies in the fact that it allows you to more effectively accumulate useful mineral substances from the soil. In addition, it has long been noticed that after treatment with boric acid, tomatoes become better in taste, as they accumulate more sugars. And these are not all the obvious benefits of using this simple, affordable tool.
Boric acid for tomatoes
It turns out that the processing of tomatoes with boric acid is nothing but another stage of feeding garden crops. Nowadays, when most of the soil is severely depleted, especially its upper layers, the importance of introducing boron into the soil only increases.
Using Boric Acid for Tomato
It is known that feeding with boron namely vegetable crops especially helpful. For comparison, cereals, for example, absorb 10 times less boron than dicotyledonous plants.
And tomatoes, cucumbers with sufficient accumulation of boron significantly increase productivity. In the case of adding boric acid to tomatoes, two methods of feeding are widespread:
- Boric acid solution the whole aerial part of the plant is processed.
- The same solution can be used for root dressing.
Interesting! It is believed that simple spraying of the aerial parts of tomatoes with boric acid is better, since the production of chlorophyll increases, the stem and root become stronger, the plant better resists diseases and pests in general.
In the natural environment, boron in the free state is practically not found. Plants draw this element necessary for their development from salts that are contained in the soil. It has long been known that boron in tomatoes affects:
- flowering productivity;
- reduction in the number of empty ovaries;
- fruit resistance to adverse conditions (in particular, high humidity);
- increased sugar content in fruits;
- reduced risk of late blight of tomatoes;
- Better fruit preservation after harvest.
It is interesting! By the way, boron is found in many fertilizers and in a free state too. But the most common, affordable and simplest treatment is boric acid.
It is also known that boron is very poorly accumulated in the soil, it is easily washed out during rains or irrigation. This must be taken into account, so tomatoes will have to be processed relatively often.
The optimal amount of boron in the composition of the garden culture can significantly improve many internal processes and the synthesis of minerals in general. So, the assimilation of nitrogen from the soil is significantly improved. In the case of tomatoes and cucumbers, boron allows cells to divide faster, which makes the fruits ripen faster and are large.
In addition, boron helps to improve the metabolism of carbohydrates and proteins, affects the efficiency of pollination and fertilization of the ovaries at the time of flowering.
But boric acid can cause significant damage to plants, up to complete death. Malicious effect associated exclusively with overdose. Excess boron causes leaf burns, which quickly begin to dry and fall off. Thus, the whole plant is difficult to tolerate large concentrations of fertilizers based on boron.
This means that it is necessary to carefully monitor the content of the mixtures and apply them in the exact concentration indicated on the package or recommended in the recipe. Also, boric acid should not be used more often than known treatment methods advise.
Signs of a lack of boron
As a rule, it is easy to determine the lack of boron by the appearance of a tomato. Experienced gardeners even more quickly notice the need for boron treatment.
- Firstly, the lack of minerals demonstrates the weakening of the upper part of the bushes.
- When the external environment is especially poor in boron, the upper shoots begin to curl, and in the worst case, dry up and fall off.
- Also, on tomatoes that are not treated on time with a solution of boric acid, many empty flowers are formed.
- At later stages, not only on the leaves, but also on the fruits, dry spots form.
In general, it is possible to understand that a tomato lacks boron even if the plants look weak, stunted, most of them are ill at all stages of growth and weakly take root.
Signs of Boron Excess
On the other hand, any type of top dressing is harmful even when they are introduced too often and plentifully. It has long been noticed that tomatoes can also suffer from an excess of boron. Basically, this is expressed:
- The leaves acquire a glossy sheen - exactly the same as with an excess of nitrogen in the plant or soil.
- Dry spots begin to appear on the leaves, bordered by concentric circles. If you do nothing (namely, water the plant more often and exclude fertilizing), then the entire leaf plate is affected quite quickly until complete dying.
- The leaves do not become flat, but curved in the middle like a dome.
In most cases, an excess of boron does not appear immediately. First of all, old leaves suffer (dry parts appear) or the top of the bush. Only then the rest of the bush withers down to the stem. So the problem can be noticed on time and have time to save the bushes.
Boric acid as a fertilizer and fertilizer for tomatoes
Boric acid is considered to be the easiest option for feeding tomatoes at different stages of growth.
The preference for this tool is given mainly because it is often found on sale, and also has a low price. Moreover, the efficiency of boron assimilation by tomatoes during the treatment with boric acid is high.
The optimal periods of fertilizer with boron for a tomato are the time of growing seedlings, transplanting on open ground, flowering.
An important condition. Spraying the aerial parts of the tomato should be carried out in the early morning, evening or in cloudy weather, since the bright sun in combination with boron can lead to burns of leaf plates, stems, fruits.
Boric acid against pests
Another positive quality from the use of boric acid - pest controlwhich, incidentally, are very fond of tomatoes.
- Boron is used as a poison against ants. It is enough to pour the solution before entering the anthill. You can soak in a solution of boric acid sugar, honey, other sweets that will attract insects.
- A simple spraying of the bushes will help in the fight against aphids and woodlice. It is recommended to breed 1 gr. acid per 1 liter water.
- Boric acid can help even against the bear. In this case, 1 kg of grain should be steamed and mixed with a tablespoon of acid. After that, the finished bait is displayed in the garden in different places.
Advice! It is better not to treat the pests on the hottest part of the day in the bright and active sun, because the effect of boron can be the opposite, the drug will have a detrimental effect not only on pests, but also on plants.
How to dilute boric acid for spraying tomatoes
The normal ratio of dissolution of boric acid in water for fertilizer is an no more than 2 gr. active substance per 1 liter hot water (boron dissolves without residue in water from 70 aboutFROM).
When it comes to processing against pests, then the dosage will be effective when diluted from 1 gr. for 1 liter water.
Among other things, there are many recipes for combining boric acid with other substances useful for the growth of garden crops.
Mixtures with iodine have also proven themselves in the processing of tomatoes. Iodine is mainly used to disinfect and enhance the immunity of tomatoes..
The first treatments (at the stage of seedling and the formation of ovaries) do not intersect with the addition of boric acid. But then, when the bushes have grown, tomatoes begin to ripen, you can carry out complex dressing of plants with simple watering under the root.
The mixture is prepared by adding 5 l. hot water 3 kg of wood ash. After this, you need to wait for cooling and pour a complete vial of iodine (10 ml.) And 10 gr. boric acid.
Further, the mixture can not be made in pure form, but diluted in a ratio of 1 to 10 with clean water.
Manganese solution can be used to treat tomato seeds before transplanting.
The solution is prepared from 0.5 g. boric acid powder per 1 liter. hot water (at least above 55Cabout) A drop of potassium permanganate is added to it (about 1 gr.). By the way, it is better to lower the seeds in a bag of gauze so that they do not float.
Soaking time - from 12 to 24 hours immediately before planting.
This technique significantly improves seed germination, tempers future tomatoes and, in a positive way, affects crop yields.
If there is a problem of shedding ovaries on already mature tomatoes, it is recommended to dilute a weak solution of boric acid: 1 gr. for 10 liters warm water. It is noteworthy that with this method of treatment, the sprayer should only fall on the ovaries and the first flower buds, trying not to capture the leaves, the stem.
By the way, this method is perfect for pollinating plants and stimulating better growth in a greenhouse where there are not enough insects for the natural spread of pollen.
If tomatoes suffer from late blightthen boric acid will help here. To do this, dilute 1 teaspoon per 10 liters. You need to roughly understand that in a teaspoon without a slide, about 5 grams. powder. If boric acid was purchased in bags, then usually packing is 10 g. That is, you need to apply half the package.
How to use during flowering?
The treatment is carried out with a spray gun with a small cross section for strong atomization. It is not recommended to get this solution on the green mass of bushes, trying to capture only parts of the inflorescences.
Which solution to use to stimulate the ovaries
When flowering and the appearance of the first ovaries apply, as a rule, weak solutions of boric acid (proportion of about 1 gram. of warm water).
How to use for seeds?
Seeds may be soaked in boron solution (dosage is indicated by the manufacturer on the bag: 0.5 g for 1 liter water) The main condition is to use warm water and withstand seeds in it for at least 12, no more than 24 hours before planting.
How to breed to feed cucumbers
As with tomatoes, a solution of 1- is used for cucumbers.2 gr. boric acid per 1 liter. water.
Attention! There is one difference: in cases with tomatoes, spraying the aerial part of the bush is more effective, and root fertilizer is better perceived by cucumbers.
Dosage, proportions and processing steps
The use of boric acid solution should be no more than once every 10 days. But the processing stages at the growing stage, in general, are many:
- Feeding can be started by soaking the seeds.
- Seedlings are later processed.
- When planting in the open air or in a greenhouse.
- When the tomatoes bloom.
- When tying the first fruits.
- At the beginning of fruiting.
The standard dosage for direct processing of the aerial parts of flowers usually varies in proportions from 1 to 10 grams. warm water.
If fertilizer is applied under the root, then you can breed up to 2 grams. warm water.
Contraindications boric acid use
Boric acid cannot be used:
- On a clear day, except in the morning and evening hours.
- In windy weather.
- With a high content of lime in the soil.
In other conditions, boron is absorbed by plants, but only about 3-10% of its total content in the soil.
Boron does not cause burns or irritation on skin contact.. If the solution gets on the mucous membrane, it is enough to rinse the affected area with plain water.
However, boron can be absorbed by the human body and accumulate in it. Excesses of this substance are excreted difficult and for a long time. From this point of view, when using boric acid it is better to use gloves and not to get on the skin.
- Due to inexperience, gardeners can be too frequent with boron treatments. But this should never be done. Breaks between treatments should be at least 10 days.
- If you use boron for horticultural crops on a hot day, you can burn most of the leaf blades.
- The simultaneous use of boric acid and lime leads to the full use of boron by microorganisms in the ground, and almost nothing gets to the tomatoes.
- You can not increase the concentration of boric acid in the selected mixture for fertilizer. Strictly no more than 2 gr. necessarily hot water per liter.
- Boron is well soluble only in hot water. In cold, it almost completely precipitates.
Boric acid is a universal and effective tool for growing tomatoes on the open ground or in the greenhouse. The main qualities that have made this product popular are its availability, low cost and ease of use.
