The benefits of boric acid for tomato wilting
The product is mainly used during the flowering period of the vegetable crop, as boron has a positive effect on bud wilting. The element is extremely important for garden plants, so it is a part of many industrial fertilizers, which are sold in specialized stores. The substance has positive effects on tomatoes:
- provides accelerated growth and active bush development;
- promotes rapid absorption of nutrients from the soil;
- normalizes and activates metabolism;
- promotes development of a large number of ovaries and prevents early flower shedding;
- reduces the number of empty blossoms;
- provides fruit retention;
- improves tomato taste and presentation
Boron also has the ability to increase pollination efficiency of the vegetable crop and has a positive effect on the process of ovary fertilization during flower stalk development. This is especially important if tomatoes are grown in unsuitable for them soil or infertile substrate.
Lack of substance causes a depressed state in tomatoes, because of poor immunity, bushes are more often attacked by pests, affected by diseases. With boron starvation the plant grows poorly, the coherence of development processes is reduced. As a consequence, the quality and quantity of the tomato harvest decreases.
How to dilute boric acid for tomatoes
Boric acid is available as a powder, which has no color and no smell. It can be purchased at any drugstore or garden store.
Boric acid aqueous solution for tomatoes is prepared in different ways, all directly depending on the purpose of the fertilizer:
- feeding tomatoes when there is a lack of boron, causing the vegetable crop to grow poorly and bloom sparingly;
- to increase and strengthen the ovaries;
- preventing against fungal diseases.
The preparation is rather difficult to dilute in water, so it should be dissolved in warm liquid, the temperature should be about +50-60 ° C. If the degree is lower, the acid simply will not dissolve, if higher, there is a risk of losing the useful properties, i.e. spraying will not provide the desired effect. You can buy the product at the nearest pharmacy, it costs inexpensive, so every dacha can afford it.
The proportions of boric acid for spraying tomatoes
When preparing the solution, you must strictly observe the proportions, an excess of boron affects tomatoes as bad as its deficiency. The preparation is prepared according to the instructions:
- Heat water (10 liters) in a metal bucket up to 50 °Ñ;
- add 10 g of the preparation (on the base 1 g of boric acid for 1 liter of water);
- mix until the substance completely dissolves.
After the liquid cools down you can water or spray directly. If the solution is used to control phytophthora (a fungal disease), different proportions are followed - one tsp of powder is taken for each liter of water.
How to spray tomatoes with boric acid
Even before spraying tomatoes with boric acid for wilting and active growth, you need to know the rules for treatment. It is important to consider the following:
- spray tomatoes better in the early morning or evening, when the sun is not so bright so that the leaves do not get burned;
- the sprayer should have small nozzles, large drops can harm the tomato leaves;
- all parts of the plant should be treated, this includes the ovaries, flowers, stems and leaves;
- to ensure that the liquid reaches the back of the leaf plate, the bush is tilted slightly during treatment;
- do not treat with too cold a solution, its temperature should be the same as the soil.
Important information! When making a boric acid solution it is important to observe strict proportions. Ignoring this condition often causes the vegetable crop to stop growing and, in some cases, even die.
When to treat tomatoes with boric acid
Treatment of tomatoes with boric acid for wilting is performed three times:
- The first time the procedure is resorted to two weeks after planting seedlings in the open beds or in the greenhouse. The procedure is performed for preventive purposes, it reduces the risk of phytophthora and other diseases.
- The second time it is recommended to water the tomatoes with boric acid for setting during the budding period. This stimulates the plant to produce more inflorescences and form them. Also spraying promotes faster flowering.
- The third treatment of tomato bushes is carried out during the period of active flowering. Boron will have a positive effect on the plant, preventing premature drying and flowering.
Please note: Spraying is carried out taking into account the reaction of the vegetable crop to the solution, if a positive effect is observed, then you can spray tomatoes with boric acid for wilting and further. If the tomatoes react badly, however, the procedure should be abandoned.
What could be the problems
One of the frequent mistakes that leads to problems with tomatoes is the wrong dosage when preparing the solution. An overdose of boron is just as bad for tomato plants as a lack of boron. It is easy enough to identify overdose, as indicated by the following symptoms:
- dark brown spots form on the leaf plates;
- the spots gradually attack the entire leaf, after which it begins to die off and fall off;
- in a neglected form the apex part curls up.
Signs of overabundance of boric acid appear from the lower part of the plant, gradually passing to the top of the tomato bushes. If the problem is not corrected, there is a risk of developing marginal necrosis, the tomatoes in this case simply stop growing.
The situation can be corrected by abundant watering, boron rather quickly washes out of the soil. You should also stop spraying with boric acid in the near future.
Cautions! An improperly prepared solution for watering tomatoes with boric acid for wilting can cause burns if the concentration of the substance is exceeded. If it is not enough, such a spraying will have no positive effect.
Can the same boric acid recipe be used for cucumbers?
Cucumbers, just like tomatoes, are in dire need of boron. It is this substance that determines the number and condition of the ovaries. In addition, the element helps the absorption of calcium and promotes active and proper cell building.
Cucumbers should be given regular spraying with a solution of boric acid in dry summer. This is because in drought the plant simply does not have enough energy to extract boron from the soil. Deficiency of the substance badly affects growth, flower formation, ovaries on the vegetable crop is practically absent. The appearance of bushes also deteriorates, leaves thicken and wrap inside.
The same solution can be used to spray the vegetable crop as for tomatoes. The recommended proportions are 1 gram of powder per liter of hot water.
Boric acid is considered to be an excellent helper for gardeners, the preparation has a positive effect on the growth and development of garden plants, including tomatoes. Spraying the bushes with a properly prepared solution will provide gardeners with a rich harvest even when growing vegetables in scarce soil and unfavorable conditions.
