Why the leaves of the plants turn yellow and how to fix it

In this post, we explain how to solve the problems of our plants when the leaves turn yellow.

The yellowing of the leaves is a common problem in the plant kingdom. In this post, we explain what the main reasons why the leaves of your plants suffer from yellowing are and how to solve it easily and simply. Anyway, you can get other tips by visiting landscapers Falmouth.
Causes of yellowing:

It is true that the leaves tend to turn yellow and dry by the life cycle of the plant itself. But that’s not a problem; it’s the end of that leaf’s life cycle. However, on many occasions some leaves that should be green begin to turn yellow. These causes can be different:
Excess sun exposure

When a shade plant has a direct exposure to the sun or excess luminosity. It is something that can happen to shade plants like the giant spathiphyllum. The solution is very simple, as you need to reduce the exposure by placing each plant in its place, sun plants in well-lit places and shade plants in shady places or protected from light.

Yellowing due to lack of iron

When the plant does not find enough iron in the soil because the pH of the soil does not match what the plant needs. Plants that are acidic can absorb iron if the soil is acidic. If the plant is not in these optimal conditions, ferric chlorosis occurs, which we have already mentioned on other occasions. Gardenias, hydrangeas, gerberas … can suffer from chlorosis.

Yellowing due to lack of nitrogen

The growth factors of plants are nitrogen, phosphorus and potassium. Nitrogen gives greenness and growth, phosphorus and potassium help the roots and flowering. For example, the Melissa, which is a very vigorous plant, being in a very small container has already exhausted all the nutrients and therefore its leaves begin to change color, this indicates lack of fertilizer.

How to solve these problems:

For excess exposure the solution is simple, that’s to avoid excess sun exposure.

Why the leaves of the plants turn yellow and how to solve them


Incorporating specific products with irrigation or in the form of balls that we will incorporate as a fertilizer on land. Also contributing iron chelate to irrigation water will provide the iron that the plant needs to perform photosynthesis.

Lack of nitrogen
It implies lack of nutrients for the plant, so the solution is to provide nutrients with liquid fertilizer or substrate.

Remember, that yes, not all plants that have yellow leaves something happens to them. There are plants whose color is yellow, but usually, if we see that they change color is an indicator that something may be happening.

We hope these tips help you to have your green plants, healthy and vigorous.
