The main reasons why tomatoes blush


The uneven color of the tomatoes is not a signal about the disease of the plant, but speaks of errors in the care of tomatoes. To find the essence of the problem, it is necessary to understand how tomato ripening occurs.

Tomato ripening

The development of tomatoes consists of two stages: in the first stage, the growth and formation of the fetus occurs, in the second stage, over the course of 3 weeks, the resulting fruits begin to acquire a red or brown hue.

  2. Uncomfortable temperature. Improper adherence to the temperature regime, or rather the elevation of the mark plus 35 degrees, will provoke a stop in the production of a natural pigment - lycopene. Lycopene and makes tomatoes red.
  3. Bad light. Inadequate exposure to sunlight, due to too dense planting of tomato bushes. As a result, the ripening of the fetus is disrupted, leading to uneven color.
  4. Lack of nutrients. The reason for the shortage is the improper implementation of feeding, that is, with an excess or deficiency.
  5. Busy loads of fruit. A common reason for inexperienced growers. An improperly formed bush, on which there is an excess of stepson and brushes and forms the very congestion. The result is a large number of fruit brushes and a tomato bush unable to provide each tomato with nutrients.

If an error is detected, you should immediately take measures to eliminate it. The quality of the crop directly depends on the correct care of the plant. We propose to consider in more detail how to correct the situation.
