The yellowing leaves may turn into a nightmare for many farmers. They can gradually become all yellow, or yellow only on the edges, with a tendency to brownish. Each of these conditions of yellowing of the leaves represents a potential danger to the health of our plant. In this article, I will present why is my plant turning yellow and how to fix it?
Sometimes it can be a disease that affects only the leaves. It arises and spreads on the plant since the fundamental chlorophyll photosynthesis occurs in the leaves. This is not the only case: yellow leaves can also be a symptom of deficiencies and diseases affecting the stem or roots. The leaves then turn yellow due to a lack of other nutrients.
The case of autumn yellowing of the leaves is different. In autumn, the leaves dry naturally. For this reason, their appearance and their color change until the fall in winter.
Why is my plant turning yellow?
If your plants turn their leaves yellow, they may be telling you something, it is a common problem in plant care, and it can be due to various reasons. The most common are:
Iron chlorosis (lack of iron ) for any of these reasons, if it lacks essential nutrients, such as iron, your plant will end up being affected. The lack of iron is one of the common reasons why the leaves can look yellow. When this occurs, the symptoms begin to be noticed on the younger leaves and on the outer part of the leaf.
Excess moisture. Excessive watering or leaving the pot puddled to absorb the water will yellow the leaves and dry the tips or even cause all the leaves to fall off.
The low temperatures can also cause yellow leaves and air currents in plants.
Yellow leaves from excessive watering
Especially beginners tend to give more water than is necessary.
Plants suffer from yellow leaves due to too much water: the risk is to weaken the roots or moisten the soil too much and not allow the right nutritional intake.
The roots are real transfer channels from the soil to the plant, so they must always be preserved from water stagnation and diseases such as root rot.
Another very frequent case of yellow leaves occurs when the leaves are wet during watering. It is always recommended to wet only the ground and to always keep the leaves dry, except, of course, the natural morning dew.
Yellow leaves due to environmental factors
In addition to nutritional deficiencies, several environmental factors can cause yellowing of the leaves.
Among these, the most common are:
Lack of sunlight. Plants placed in shady areas can suffer from yellow leaves, or in any case, from withered or dull-colored leaves. This occurs due to the reduced production of chlorophyll. The solution is to move the plants to a sunny area.
Dehydration. Even infrequent or inadequate watering or leaving the plant with the soil dry for too long can dry out the roots and weaken the leaves. Water is the most valuable asset for chlorophyll photosynthesis.
Wind exposure. The strong wind tends to weaken the leaves, especially the younger ones. This is why it is useful to repair the plant or move it to less windy areas.
How to fix yellow leaves on plants?
A contribution of iron chelate will return the necessary nutrients to the plant and will promote the creation of chlorophyll.
Reduce watering by waiting until the substrate is almost dry before watering again.
Avoid waterlogging. If the plants are in pots, check that the drainage is adequate, drill several holes if necessary for the plant to evacuate excess water or change it to a larger pot.
Know the pH of the soil to correct it.
Remove leaves that are completely affected, as they will not turn green again and will attract plants.
If the reason is excessive cold, appropriately.
Avoid excess chemicals, instead use other products that are ecological, such as Neem extract.
Find out if your plants are annuals and if they are already at the time of drying, or if they are deciduous and lose their leaves naturally by the time of year they are.
