Boron is a valuable microelement that significantly affects the quality of fruits.
According to the expert of the online publication Belnovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh , you can understand that tomato bushes lack boron by their appearance.
If you see that the top of the foliage dries out, but the side shoots continue to grow, this is one of the signs of a lack of boron. Sometimes in this case, the top dries out completely.
On the fruits you can see dry spots that are brown in color.
A lack of boron is also indicated by the fact that flowers fall off during the flowering period.
Very often in such a situation the flowers have an irregular shape. On the bushes you can often find so-called "double" inflorescences.
In addition, tomato leaves curl and gradually become lighter, and the fruits become small.
In this case, it is worth considering feeding with boric acid. In addition, other useful substances should be included in its composition.
For example, many summer residents advise boiling 10 liters of water with the addition of 2 liters of ash, and after the liquid has cooled to 60-70 degrees, 1 teaspoon of boric acid and 30 drops of iodine are added here.
For one plant you will need 0.5 l of the resulting mixture.
