Sometimes, it happens that the leaves of tomato plants turn yellow. And since we know how worrying this can be, today we present to you all the possible causes of the yellowing of the leaves of these plants. Discover without delay the factors that are at the origin of a tomato with yellow leaves and the possible treatments according to the experts.
Here’s What Can Cause Yellowing Tomato Leaves
Tomato with yellow leaves: why and what to do? Here is the advice of the experts
To be able to treat your tomatoes with yellow leaves, you will first need to find the cause. In fact, according to the experts at Gamm vert, it is not only diseases that can cause yellowing of the foliage, but also parasites, some “cultivation errors in watering or fertilizer”.
In fact, Gerbeaud specialists explain that it is “from the disappearance of chlorophyll”, a phenomenon called chlorosis. This can be due to “asphyxiation of the roots due to excess water, water stress caused by insufficient water supply, cold snap or soil that is too chalky”according to them.
This is due to improper watering, most often
Although yellowing leaves can be a cause for concern, I would like to tell you that it is a very common problem that many gardeners have encountered at least once.
Now we’ll take a closer look at the most important thing, that is, all the possible remedies to cure a tomato plant with yellow leaves.
Watering
Since improper watering is one of the most common causes of yellowing tomato leaves, it stands to reason that the first thing to do is adjust the water supply.
These plants need regular, but not abundant, watering.
In fact, according to experienced gardeners, these plants “do not need large amounts of water ». In reality, tomatoes require regular, but not abundant, inputs. You also have to be careful not to soak the plants. Ensuring good drainage of the soil is another key element for having healthy tomatoes. Otherwise, you risk rotting the roots, a condition that leads to asphyxiation of the latter.
Tomato plants must be watered well, as they are susceptible to rot.
On the other hand, sometimes tomato leaves turn yellow due to severe lack of water. In this case, the leaves hang down, turn yellow and dry out. To save your plants, water immediately and copiously, waiting for the water to drain if you are growing them in pots.
Deficiency
To find out if it is a nutrient deficiency that can also cause yellowing of the foliage, experts recommend starting by observing the leaves and then doing a soil test. This way, you will know if it is nitrogen, phosphorus or potassium that is lacking and then make amendments and rectify the problem.
Sometimes when yellow leaves have black or brown spots, it can be a sign of calcium or manganese deficiency.
Nutrient deficiencies may also be a cause.
Yellow leaves with very green veins, however, are a characteristic sign of chlorosis, caused by a lack of iron, magnesium or nitrogen.
And soil analysis is the best solution here to find the origin of the problem.
Diseases/parasites
Yellow leaves can also be caused by a disease or a parasitic infestation. This is the case with the ToCv virus, virosis, mosaic, the spider mite which is a mite that attacks tomatoes, verticillium wilt (here, we also notice a rolling of the leaves), alternaria which attacks not only the leaves, but the fruits as well.
If it is a disease or pest infestation, know that there is not much that can be done to save the affected plants. That is why experts strongly recommend taking action upstream to eliminate any risk. All you have to do is properly maintain your tomato plants.
