Have you ever wondered why tomatoes turn black at the tip? Unveiled the arcane. We only anticipate that it is not for lack of water. Here’s the real reason.

Why do tomatoes turn black at the tip

It will also have happened to you to witness the deterioration of the quality of a tomato. You will have seen that these vegetables often turn black at the tip. Why does this happen? It is not the fault of the lack or poor watering.

How to best care for tomato plants

Impossible not to love the tomato. Its strong but sweet flavor at the same time, is appreciated by the palates of gourmets from all over the world. Italy is among the nations that most produces, imports and exports abroad these tasty fruits that are consumed especially in summer.

Tomato harvest

If you have the opportunity to grow a tomato plant in pots or in the garden, we advise you to do so: if you follow some tips you can enjoy this inedible and tasty garden product throughout the summer season.

But how do you care for a tomato plant? There is some information that you must necessarily know. To make it grow well and to have many fruits, you must:

  • water the plant every other day;
  • bury it in moist and drained soil so that the roots take root well;
  • expose it in a very bright area;
  • prune it frequently by cutting the buds that come out under the leaves and the stem;
  • Feed the soil with natural fertilizers if you notice that your plant is struggling to grow.

You realize that your tomato plant is not growing in the right way not only if it produces few fruits but especially if the latter begin to color the tip of black. Why does this phenomenon occur? No, it does not depend on the lack of water.

Why do tomatoes turn black at the tip

You may have noticed that not all tomatoes are the same. Of course, there are different varieties that define the shape, color and flavor of the fruit.

Surely, however, there is something that unites all tomatoes regardless of variety: the black color that often appears on its tip. What is this curious phenomenon? Why does this happen? Let’s answer these questions.

Black tomatoes at the tip

The main reason why tomatoes turn black at the tip is this: calcium deficiency that is scarce among the nutrients of the soil. The absence or too low quantity of this nutrient necessary for fruiting, is manifested by necrosis on the lower part of the fruit (the tip, to be clear) and with an internal rot that makes the tomato clearly inedible.

Having established this, we can therefore exclude that the black color at the tip does not depend on the lack of water. At least not totally. We need to make a specification in this regard too.

Plants to grow healthy and strong must absorb calcium which is present in a well-fertilized soil. All the nutrients the plant acquires them through the roots which in turn absorb them from the substrate of the soil in which, among the various nutrients, calcium is also found.

What happens if you water a tomato plant too much or too little? There are two consequences:

  • if you overwater the plant, its roots drown and are not able to absorb the most important nutrients such as calcium;
  • If you water the plant too little, the roots do not grow and cannot absorb nutrients and therefore also calcium.

That’s why it is more correct to say that tomatoes turn black at the tip because they cannot absorb calcium as they should, but also due to incorrect irrigation.

Can I fix this? The answer is yes. In what way? Integrating calcium into the soil. Supplementation can take place either through fertilizing the soil with supplements that contain this essential nutrient for the plant, or using natural ingredients.

Milk for example, which is a drink rich in calcium, can help the plant absorb the right amount of this nutrient. Pour 250 ml of milk into a liter of water and water the soil and leaves of the tomato plant.

You can also use powdered milk if you prefer. In this case you will need to spread a generous amount on the substrate and then proceed with watering the plant.

According to some studies, however, there would also be other causes responsible for the so-called apical necrosis, namely the too sudden growth of the plant that has received excessive nitrogen integration or poor water drainage.

The solution to solve all these problems is therefore to nourish the soil with natural calcium supplements but above all to pay attention to irrigation: the so-called water stress must be avoided.
