The benefits and harm of boric acid
Cucumbers are particularly acutely affected by a lack of soil boron in the soil. dry periods. To identify the lack of this element is quite easy by inspecting plants and fruits.
With a lack of boron, the plants develop poorly, there are few flowers and ovaries, the young leaves become dense, and their edges are wrapped down, cork-like spots are visible on the fruits. If the boron deficiency is large, then the flowers and the ovary fall off, and the roots have an orange color.
If even two of the above symptoms are found on the cucumber bed, it is necessary to help the plants and provide them with the missing substance. 
Boric acid for plants with the right dosage will bring indisputable benefits:
- It will be better to develop the root system.
- The intensity of flowering and, accordingly, the amount of the ovary will increase.
- The leaves will be healthy due to the acceleration of the process of photosynthesis.
- The taste of the fruit will be improved by increasing the amount of sugar.
- Shoots will be strong and healthy.
- Fruits are better preserved.
However, boron refers to the feeding that can not be made in advance, just in case. Its excessive content in the soil leads to burn leaves. This is clearly visible on the old and lower leaves that turn yellow, their edges dry and the leaves fall off. In addition, the use of boron-fed cucumbers can harm human health, especially it is dangerous for people with diseased kidneys.
Terms of use
When processing seeds and conducting dressings, it is necessary to observe the permissible concentration of the substance, not exceeding it. Boric acid for cucumbers has found its use in pre-sowing seed treatment and as foliar top dressing. 
Seed treatment
Bor promotes improve seed germination. Processed by potassium permanganate seeds soaked in solution for a maximum of 12 hours. To prepare such a stimulator, 0.2 g of acid powder and 1 liter of hot water will be needed.

If you add 100 grams of sugar to a standard solution of boric acid, it will help attract insects, which contributes to an increase in the number of ovaries on pollinated varieties.
Spraying Cucumber Boric Acid spend not only to increase the ovary, but also to prevent the fall of flowers, in particular, female. To do this, dissolve potassium permanganate and boron powder in a bucket of water - 2 g of each product. The treatment is carried out at the beginning of flowering. If you add another 40 drops of iodine, you get an excellent tool for the prevention of bacteriosis, powdery mildew, root rot. 
Spraying of beds is carried out in windless dry weather, preferably early in the morning or after sunset, and they do it three times per season: during the period when the buds appear, during flowering and when fruiting has begun.
