A vial of iodine for disinfecting cuts and abrasions is probably in the first-aid kit for everyone. But experienced gardeners know that feeding with iodine can help strengthen seedlings, accelerate fruit ripening, and fight disease.
Many discoveries are made as a result of accidental coincidence during idle idleness. They say that an apple helped Newton to become truly outstanding, and Archimedes would not have shouted his famous “Eureka!”, If he had not decided to soak in the bathroom.
According to one legend, iodine was invented by a cat. Its owner, Bernard Courtois - a French chemist and pharmacist - decided to play with his pet. But the cat suddenly jumped into the test tubes, breaking them. The contents of the tubes mixed up, rising into the air in the form of a violet vapor and immediately settling. This was iodine.
And although we are accustomed to using it to disinfect broken knees or garden cuts, iodine is much more multifunctional and can be successfully used in garden beds both for feeding plants and for fighting diseases. The main thing - do not exceed the dosage and remember that not all plants benefit from iodine.
Iodine is necessary for the normal course of a number of biological processes. When applied to the soil, its effect is somewhat similar to the action of nitrogen fertilizers. In addition, it works as an antiseptic, destroying a number of harmful microorganisms. Iodine can be useful for cabbage, cucumbers, tomatoes, eggplants, and garden strawberries.
To 3 l of water add 1 drop of iodine and, having carefully mixed, water the seedlings under the root. Feeding is carried out no more than once. Iodine helps young plants to get stronger and more successfully resist diseases.
