Why Are Eggplant Leaves Turning Yellow?
1. Nutrient deficiency

| Solution | Increase fertilizer application to address nutrient deficiency in eggplant leaves turning yellow. |
Nutrient deficiency, particularly the lack of nitrogen, can cause eggplant leaves to turn yellow. Nitrogen deficiency is the most common cause of yellowing leaves in eggplant. When the plant lacks the appropriate amount of nitrogen, it can’t carry out necessary functions such as photosynthesis efficiently. This leads to chlorosis, a condition where leaves turn yellow.
To remedy this situation, you should apply a balanced fertilizer to the soil, particularly ones that are high in nitrogen, phosphorus, and potassium. Regularly check your plant’s soil and water conditions. Overwatering can lead to nutrient leaching while underwatering can prevent nutrient absorption.
Aside from nitrogen, other nutrients like iron, magnesium, and zinc when deficient may also cause the plant leaves to turn yellow. Therefore, using a complete plant food that contains these essential nutrients is recommended. Lastly, the soil pH can affect nutrient availability. Hence, maintaining a soil pH between 6.3 to 6.8 will ensure these nutrients are readily available for plant absorption.
2. Overwatering

Effects of Overwatering on Eggplant Leaves
Overwatering causes root suffocation and decay, which affects the overall health of the eggplant. When eggplant roots fail to hold necessary amounts of oxygen due to waterlogging, they can’t effectively consume nutrients and this deficiency is reflected back on the leaves, causing them to turn yellow.
Solutions to Overwatering
The most effective solution is to adjust your watering schedule. Eggplants need moderate amounts of watering, so don’t keep the soil constantly soaked. Give the plant a good soak and then let the soil dry before watering again. Ensure the chosen spot for your eggplant has good drainage and if grown in pots, it should have drainage holes. This allows excess water to escape and prevents waterlogging, maintaining the health of your eggplant.
3. Underwatering

| Solution | Increase watering frequency to provide sufficient moisture for the eggplant leaves. |
If your eggplant leaves are turning yellow, it may be due to underwatering. Plants, like eggplants, need adequate water to facilitate various biological processes, including photosynthesis and nutrient absorption. Nutrient deficiencies or lack of hydration may lead to discoloration in leaves, including turning yellow.
Providing solutions, the best way to rectify underwatering is by adjusting your watering schedule. Regular, deep watering is recommended for eggplant’s growth. On average, an inch of water per week, including rainfall, is sufficient. However, in hotter, drier climates, you may need to increase the frequency. Avoid watering on the leaves to prevent fungal diseases. Also, ensure your plant is planted in well-draining soil to prevent waterlogged conditions. A layer of mulch around the base of the plant can help retain moisture, reducing the frequency of watering and helping maintain consistent soil moisture.
4. Pests or diseases

When it comes to pests and disease, these can infest an eggplant and cause significant symptoms, such as yellow leaves. Specifically, pests such as aphids, spider mites, leafminers, and beetles can sap the plant’s vital nutrients, leading to discolouration and leaf wilting. Diseases like Verticillium and Fusarium wilt can also cause yellowing.
The first step to remedy this problem is detection. Carefully inspect the eggplant’s leaves, stems, and surrounding soil for signs of pests. If pests are identified, treatment can involve methods like washing the plant with a mild soapy solution, using natural predators, or applying pesticide according to the product’s instructions.
In terms of disease, if the problem is a type of fungal infection, removing and discarding infected parts of the plant is paramount, as these fungi thrive in moist, cool conditions. Ambience plays an essential role in the vitality of the plant, so providing proper watering practices and ensuring good air circulation and sunlight for the eggplant are beneficial in preventing disease. Lastly, crop rotation is advisable to minimize the chance of disease return.
5. Excessive heat or sun exposure

|---|---|
| Solution | Provide shade or move the plant to a cooler location to prevent excessive heat or sun exposure. |
Excessive heat or sun exposure can stress eggplant plants, leading to their leaves turning yellow. This occurs because the intense light and heat can damage the plant cells, disrupting photosynthesis, and causing chlorosis or yellowing of the leaves.
To combat this problem, it’s important to provide the eggplant plant with adequate shade during the hottest parts of the day. Homemade or bought garden shades can be very useful for this. Furthermore, ensure that the plants are well-watered to prevent dehydration. However, be careful not to over-water as this could lead to root rot which can also cause the leaves to yellow. Mulching around the base of the plant can help retain soil moisture and keep the roots cool.
In addition, you might want to consider planting your eggplants in an area of the garden that receives less direct sunlight, or has partial shade during the hottest parts of the day. With these measures in place, your eggplant’s leaves should regain their vibrant green color in no time.
6. Aging or natural leaf senescence

| Solution | Prune off yellow leaves to promote plant health and encourage new growth. |
When eggplant leaves are turning yellow due to aging or natural leaf senescence, it means that the plant is progressing through its natural life cycle. Senescence is the process where cells age and eventually die, which commonly results in yellowing or browning of leaves. In eggplants, this phenomenon is usually observed in older, lower leaves.
To manage natural leaf senescence, there’s no particular action needed, as this is part of the plant’s growth and maturation process. However, good overall plant care can help ensure the plant remains healthy. This includes regular watering, fertilization, good soil health, and adequate sunlight exposure. No treatment is required for natural senescence, but removing the yellow leaves can help the plant divert its nutrients and energy to new growth and fruit production.
7. Environmental stress

|---|---|
| Solution | Provide adequate water, nutrients, and temperature control to mitigate environmental stress on the plant. |
One major reason for eggplant leaves turning yellow is nutrient deficiency, particularly a lack of nitrogen. Nitrogen plays a pivotal role in photosynthesis, a process plants use to transform sunlight into energy. Without sufficient nitrogen, the leaves may lose their green pigment and turn yellow, leading to reduced plant vitality.
The solution to this problem is to fertilize the plants appropriately. This can be done by adding a nitrogen-rich fertilizer to the soil. It’s important to follow manufacturer instructions when applying fertilizer to prevent over-fertilization, which can be as detrimental as under-fertilization. Another good practice is to regularly test your soil to ensure it contains the right balance of nutrients for your plants. For a more organic approach, incorporating well-rotted manure or compost into the soil can also help replenish nitrogen levels.
