In drought, cucumber seedlings most often suffer from a lack of boron in the soil. Timely inspection of garden crops will help detect a lack of this element.

Boron deficiency negatively affects plant development:

  • an insufficient number of flowers and ovaries is formed;
  • the structure of young leaves becomes dense;
  • vegetables become corky.

If the flowers and ovaries begin to fall off, and the roots turn orange, boron deficiency has reached a critical level.

Attention! Boron deficiency causes both all of the above-mentioned obvious problems, and also reduces the resistance of cucumbers to fungal infections, for example, dry rot, bacteriosis, brown rot.

If there are at least a couple of signs of boron deficiency, cucumbers need to be urgently processed with this element.

Using boric acid in the right dosage will bring many benefits to plants:

  • The development of the root system will improve.
  • The number of ovaries will increase by increasing the flowering intensity.
  • The process of photosynthesis will speed up, as a result the leaves will become healthier.
  • The sugar content in the fruits will increase, which will have a positive effect on their taste.
  • The shoots will get stronger.
  • The shelf life of the fruit will increase.
