Why are Tomatoes not Turning Red?

Forget everything, there are only three basic reasons that do not allow your tomatoes to turn red from green.

Before going to the reasons I hope you really are near the cultivation period of this crop, rather than someone who is in a hurry to just cut them out and sell them for profit.

If your tomatoes are reaching their cultivation time, and you still have to pluck those green-looking tomatoes, keep them inside a bag, to wipe them where some will rot to death and some will survive. Then for sure, you need to know what you are doing wrong so, here are the reasons that are not allowing your tomatoes to turn red:

  1. Heat: Tomatoes grow in heat, but when they are exposed to high levels of heat for a longer duration of time, they can go under heat stress. The heat will damage the tomatoes and will not turn them as red as you expected.
  2. Cold: As we discussed earlier how high heat can damage your tomatoes, similarly if the temp is too cold then your tomatoes will not produce carotene, which is essential for the ripening of the tomatoes.
  3. water & fertilizer: if you care a lot for your tomatoes then you may spoil them with all the extra water or fertilizers that you put in them without even knowing. They will focus on growing and expanding rather than using their energies to ripe the old tomatoes first.
  4. Overgrown vines: Tomatoes have a limited supply of energy. If there are overgrown vines that are not cut off at the right time then you may get in trouble. The new growing leaves and vines take up a lot of energy and will not let your tomatoes turn green.
  5. Variety: Choosing a suitable variety is not a big deal. You should keep in mind the weather conditions and how much time you have before the weather changes before cultivation.

What happens is when the plant starts spreading it takes up a lot of energy, due to which rather than focusing on the old tomatoes the plant focuses on applying. Due to this, the old tomatoes are not able to ripe on time.

Cut some of the leaves of the plant

Another way to turn those tomatoes red on the vine is just simply removing some of the leaves of the plant. De-leafing the plant is not really a good option but listen to this. In the mid of autumn when the sun gets really low and does not emit a lot of heat, and your plant is fully grown and has blushing healthy leaves, then your tomatoes are not going to receive enough light to turn red.
