Iodine for cucumbers in a greenhouse is a good and affordable alternative to expensive industrial fertilizers and chemicals that prevent the disease of this plant. Many adherents of agriculture and horticulture have already appreciated the benefits of this simple universal remedy and have successfully used iodine to increase the yield of vegetables.

Unconventional "garden" use

A 5% alcohol solution of iodine can be found in every pharmacy. For many, it is a discovery that this effective antiseptic can be used to combat and prevent a variety of plant diseases. But those who have at least once experienced recipes with iodine in the "garden" business, begin to use it to process almost all garden crops: from tomatoes and eggplants to potatoes and strawberries.

Benefits of using iodine in gardening:

  • allows you to increase the fruiting period of plants;
  • stimulates seed germination, stem growth and flowering;
  • increases productivity;
  • increases the content of vitamin C in vegetables;
  • promotes the rejuvenation of the lashes;
  • increases the number of ovaries;
  • suppresses fungal infections (peronospore, phytophthora) in the early stages of development;
  • activates the vitality of plants.
