Why Tomatoes Don't Turn Red: 3 Most Likely Reasons
22.07.2024 19:08
Sometimes summer residents find themselves in a situation where the tomatoes they lovingly grow just don’t want to blush, and there are several reasons for this.
We suggest that we figure out what this might be connected with.
Inappropriate temperature
The best temperature for ripening tomatoes is a consistently warm temperature of 18-29 degrees Celsius.
Too high a temperature (above +32 degrees) damages the fruits, which do not ripen properly, and too low a temperature (+10-15 degrees) slows down the ripening process - in such conditions the fruits will not be able to fully reveal their taste and color.
Fertilizer error
Tomatoes need a balance of nutrients to produce the proper color and ripen properly.
If there is not enough nitrogen and phosphorus, the tomatoes will turn yellow and remain unripe, while an excess of fertilizers is fraught with excessive vegetative growth of tomatoes, which does not allow them to fully reveal their taste and color.
Lighting
Lighting plays an important role in the ripening process of tomatoes.
Tomatoes need a certain amount of sunlight to initiate photosynthesis, which produces the sugars needed for fruit development and ripening. Insufficient light can slow down or disrupt this process.
The optimal time for tomatoes to ripen is at least 6-8 hours of direct sunlight per day.
