Yellow leaves on plants

Plant leaves may turn yellow when something in their development is not going well. Among the most frequent causes that cause yellowing of the leaves we find the light, the fumes, the lack of fertilizer, the heat, the lack of water, some plants.

Let's keep in mind that some leaves have a certain yellow hue naturally, as is the case with Croton. It may also happen that some leaves turn yellow sporadically when an ordinary life cycle is ending. In some cases it happens that if in the summer a lot of water has been watered, the soil is impoverished, and if it is not fertilized with some nitrogen-rich fertilizer, the leaves turn yellow and fall.

Another cause is excess salt, in this case the yellow color may be accompanied by brown spots. This is very common in species such as hydrangeas and azaleas or in some varieties of ferns, which are very susceptible to the water components with which they are irrigated.

If you notice that your plant has yellow leaves it will be necessary to know the causes before taking any action. For that, each particular copy must be analyzed. If you do not have any pests or diseases, the plant may have an iron deficiency or chlorosis.

When a plant lacks iron, chlorosis appears, that is, that the plant does not have enough chlorophyll that generates a yellowish pigmentation in the leaves and stems. When manganese is lacking, a similar symptom appears, only that in these cases the leaves besides yellow appear with spots.

If you want to correct the lack of iron it will be necessary to use nitrogen rich fertilizers. In the market there is an important variety of products that return the green leaves, their absorption is very effective and fast.
