Si tu jacaranda is yellowIt is normal that you are worried about it, because the presence of this color on the leaves is usually a symptom that something is not quite right.
To ensure that your tree is in optimal condition, let's see what could be causing this yellowing of the leaves and what can be done to correct it.
What could be happening if the jacaranda is yellow?
If you have such a tree in your garden, even if you are growing in pots, it is sure to be the star of the space, because no one can resist its showy lilac flowers.
Therefore, when the leaves take on a yellowish color, it is normal that we want to solve this as soon as possible and, to do so, we have to know what is happening.
Biotic factors
They are related to the living organisms that influence the ecosystem that makes up your garden. That is, with insects and mites.
There are various species of insects such as aphids, mealybugs or scales, which feed on the sap of this tree. This contributes to its weakening and one of its main symptoms is the yellowing of the leaves.
The Mites, on the other hand, can cause similar damage. If they are acting on your tree, the leaves can turn yellow and fall off prematurely. The problem is that these arthropods are microscopic and you won't be able to detect them with the naked eye.
Diseases
When the jacaranda is yellow, it is not unusual for the cause to be a disease caused by fungi (in most cases), bacteria or viruses.
The mushrooms They can infect roots, trunk and leaves, and give rise to a wide variety of symptoms, including yellow leaves.
Brianda bacteria, its incidence on jacaranda is less common than that of fungi, but when they act we can see leaf spots and chlorosis.
In the case of a viral infectionIt is normal for leaves to turn yellow and for spots to appear on the leaves.
Abiotic factors
Abiotic factors are: components of an ecosystem that do not have life, but they influence the living beings that are part of it.
Among the most common we can highlight:
Nutritional deficiencies
When the jacaranda does not have enough iron, iron chlorosis may occur. This phenomenon can be identified because the leaves remain green, while the tissue between the veins turns yellow.
However, chlorosis also occurs due to a lack of other essential nutrients such as nitrogen, magnesium or manganese.
Water stress
Un excessive risk It rots the tree's roots and makes it difficult for it to absorb nutrients from the soil, a phenomenon that can lead to yellowing of the leaves.
La drought It can also be the culprit of your tree's poor appearance. If this is the case, you will notice that the leaves not only change color but also fall off prematurely.
Environmental conditions
Jacaranda leaves can turn yellow if the tree is exposed to:
- Extreme temperatures.
- Excessive sun exposure.
- Pollution.
Physiological disorders
The leaves go getting old over time and it is normal for them to lose color. This is a completely natural process and should not be a cause for concern.
Treatments when the jacaranda is yellow
Once we are clear about the cause of this phenomenon, it is time to remedy it.
To see if we are dealing with a pest, we recommend that you carefully examine the front and back of the leaves to detect the presence of insects. If the problem is them, apply a specific insecticideIn this case, we recommend starting with an organic product and, if that doesn't work, moving on to a chemical one.
If there are no insects, we will look for diseases. Fungi, bacteria and viruses cause discolouration of the leaves, but also other symptoms such as the appearance of dark spots. If you suspect an infection, apply the appropriate product to heal the tree.
If you are not applying a good watering schedule for your tree, it is more than likely that the cause of its condition is water stress. If you have overwatered Let the ground dry completely. On the other hand, if you have overdone it with the lack of watering, do a deep water supply, but without flooding.
If none of the above works, nutritional deficiencies may be the cause. To correct them, apply a foliar or soil fertilizer.
In addition to applying the appropriate treatment, do not forget to remove yellow leaves. This allows the tree to focus on healthy leaves and also prevents the spread of diseases.
What you should also do if your jacaranda has shown signs of not being as healthy as it should be is to improve its growing conditions. Make sure it receives enough sunlight to meet its needs, water it regularly and fertilize it during the active growing season.
Prevention is better than cure
In order to prevent your tree's leaves from turning yellow, the best thing you can do is to apply good prevention that includes:
- Proper irrigation, make sure it is deep, always allowing the soil to dry slightly before watering again.
- A specific fertilizer for trees.
- A well-drained soil.
- A regular pruning to remove dead or diseased branches and promote air circulation.
- Inspect the plant regularly in search of pests or diseases.
- A warm and sunny atmosphere. If your area experiences frost, protect the jacaranda from frost and also from prolonged exposure to wind.
If your jacaranda is yellowing, you know that you are dealing with a problem that can be solved if you apply the necessary care. Be patient, though, because the recovery of the trees can be somewhat slow. Apply “first aid” and then let nature do its part, and in no time your tree will be spectacular again.
