Introduction

Why is my moringa turning yellow? Moringa is a highly nutritious plant. It has many health benefits. However, sometimes malunggay may turn yellow. We will explore the reasons behind moringa tree leaves turning yellow.

Why Are My Moringa Leaves Turning Yellow?

Natural Leaf Shedding

It is normal for Moringa trees to shed their leaves during certain seasons. For example, autumn and winter. However, when moringa leaves turn yellow during other times, it may be a sign of an unhealthy tree.

Watering Issues

Overwatering: Moringa plants don't need much water to survive. So overwatering can easily be fatal for them. If a moringa tree gets too much water, it may be yellowing, wilting leaves and even fall off. On the other hand, underwatering can also lead to yellow moringa leaves.

Nutrient Deficiencies

Nitrogen Deficiency: Nitrogen helps sustain foliage and new growth. If a tree does not have enough nitrogen, the leaves may start to turn yellow or become stunted in growth.


Iron Deficiency: Iron is required for moringa trees to produce chlorophyll which helps sustain leaf greenness and new growth. When iron isn't available, it can cause the leaves of the moringa tree to turn yellow. This is especially true in alkaline soils. It can make iron unavailable for the tree to absorb.

Pests and Diseases

Common Pests: This may be a major cause of moringa plant leaves turning yellow. Many common pests can feed on the sap from the moringa plant's leaves. For example, aphids, mealybugs, spider mites and whiteflies. These pests will suck out the vital nutrients which lead to the yellowing of its foliage.


Common Diseases: Powdery mildew, bacterial wilt and root rot are common diseases. You should identify the type of disease. Take proper measures to eliminate it. Seek advice from a qualified horticulturalist if your moringa plant suffers from these diseases.

Environmental Stress

Extreme Temperatures: Extreme temperatures can cause severe damage to a moringa tree. They can lead to yellowing leaves or complete leaf loss. If you keep your moringa trees indoors, they should not get too hot or cold. If you are growing moringa outdoors, be mindful of how long it stays in the sun.


Soil Conditions: Incorrect soil composition can also lead to moringa leaves turning yellow. Without enough nutrition in the soil, a moringa tree will struggle to thrive and its leaves may turn yellow or even fall off.


Sunlight Exposure: Too much sun exposure can cause moringa tree yellow leaves or even die off. When growing your moringa trees outdoors, the area should have some shade during the hottest hours of the day. If you are growing them indoors, don't put them too close to the window.

Root Issues

Root Rot: The roots become too wet or waterlogged due to overwatering or poor drainage. They may begin to rot and cause the leaves to turn yellow.


Root Bound Plants: If your moringa tree is root bound, meaning its roots have grown too big for its pot or container. It can't absorb enough nutrients from the soil. This will cause moringa leaves to turn yellow. In this case, you can repot your plant in a larger container.

Treatment and Remediation

Remedies for Specific Issues

Overwatering Solutions: Reduce the amount of water you give your plants. Watering Moringa plants deeply once or twice a week. Use your finger to check the moisture level of the soil before watering. Avoid getting water on the leaves when watering your Moringa plants.


Another solution to overwatering is to improve the soil drainage. You can add organic matter to your soil. For example, compost or mulch. This makes it more porous and helps excess water drain away.


Addressing Nutrient Deficiencies: Before fertilizing your Moringa plants, conduct a soil test. Determine the nutrients already present in the soil. Fertilize your Moringa plants regularly. Especially during the growing season. Don't over-fertilize. Because it can lead to nutrient burns and cause the leaves to turn yellow.


You can use organic fertilizers. For example, compost or manure. Incorporate mulch into the soil to improve its nutrient content. Moringa trees are sensitive to high levels of nitrogen. So be cautious when fertilizing and follow the instructions on the package carefully.


Pest and Disease Control: Yellowing leaves can also be a sign of pest or disease infestations. You can use natural remedies to control these pests. For example, neem oil or insecticidal soap. Regularly inspect your trees for any signs of pests and address them as soon as possible.


Your trees should have adequate air circulation. Avoid overwatering to prevent these diseases. If your trees do become infected, you can try using natural fungicides or removing affected leaves and branches.


Environmental Considerations: Environmental factors can also contribute to yellowing Moringa leaves. For example, extreme temperatures, high winds, and excessive sunlight. Consider the climate and growing conditions in your area when cultivating Moringa plants.


You can provide sufficient shade for your plants to prevent sunburn. Covering your Moringa plants with a cloth or plastic sheet during the night to protect them from frost. Strong winds can damage moringa leaves. This leads to yellowing and premature dropping. Consider placing your plants in a sheltered area or using windbreaks to protect them.


Root Health Maintenance: Maintaining healthy roots prevents moringa yellow leaves. To ensure healthy roots, avoid overwatering or underwatering your Moringa plants. Overwatering can lead to root rot and nutrient deficiency. While underwatering can cause the roots to dry out and become weak.


Regularly inspect your plants for any signs of damage or disease. For example, browning or mushy roots. If you notice any issues, carefully remove the affected roots. Repot the plant in fresh soil with organic matter. Compost contains essential nutrients and microorganisms. This improves root health and promotes strong growth.

How Long does it Take for Leaves to Recover?

The recovery time for yellowing leaves depends on the severity of the issue. In some cases, simply adjusting watering habits or fertilizing can lead to a rapid improvement in leaf color.


The leaves may take several weeks to fully recover if the issue is more serious. For example, a pest infestation or nutrient deficiency. You should monitor your trees closely during this time. Make note of any changes in leaf color or overall tree health and adjust your care accordingly.

Monitoring Progress and Adjusting Care

After addressing the underlying issue causing the yellowing leaves, continue monitoring your trees. Adjusting care as needed. You can regularly prune your moringa trees to remove any damaged or diseased branches. Proper pruning techniques can improve air circulation and prevent fungal infections.

Conclusion

Why do moringa leaves turn yellow? You should keep moringa leaves healthy to fully reap their benefits. Moringa leaves turning yellow is caused by various factors.
