Why Are My Cilantro Plant Leaves Turning Yellow?

Updated: April 3, 2022

Cilantro, also known as coriander, is a popular herb used in many dishes worldwide. It is easy to grow and maintain, making it a favorite among gardening enthusiasts. However, yellowing of cilantro plant leaves can be a cause of concern for growers. In this article, we will discuss the possible reasons for cilantro plant leaves turning yellow and how to prevent it.

Lack of Nutrients

One of the most common causes of yellowing leaves in cilantro plants is a lack of nutrients. If the soil lacks essential nutrients such as nitrogen, magnesium, or iron, it can lead to yellowing or discoloration of the leaves. To prevent this, make sure to fertilize your cilantro plant regularly with a balanced fertilizer. You can also add compost or other organic matter to the soil to improve its nutrient content.

Overwatering

Overwatering is another common cause of yellowing leaves in cilantro plants. When the soil is too wet or waterlogged, it can lead to root rot and other fungal diseases that can damage the roots and cause the leaves to turn yellow. Make sure to water your cilantro plant only when the topsoil feels dry to the touch. Also, ensure that the pot or container has proper drainage holes to prevent waterlogging.

Pests and Diseases

Cilantro plants are susceptible to various pests and diseases that can cause yellowing of the leaves. Aphids, spider mites, and whiteflies are some common pests that can infest cilantro plants and cause damage to the leaves. Fungal diseases such as powdery mildew and downy mildew can also lead to yellowing of leaves. To prevent this, make sure to inspect your cilantro plant regularly for any signs of pest infestation or disease. Use organic pest control methods such as neem oil or insecticidal soap to control the pests. For fungal diseases, use a fungicide recommended for cilantro plants.

Environmental Factors

Environmental factors such as temperature, humidity, and light can also cause yellowing of cilantro plant leaves. Cilantro plants prefer cool temperatures between 50-70°F (10-21°C) and high humidity levels. Exposure to direct sunlight or heat can cause the leaves to turn yellow and wilt. Make sure to keep your cilantro plant in a cool and shaded area with proper ventilation.

Conclusion

Yellowing of cilantro plant leaves can be caused by various factors such as lack of nutrients, overwatering, pests and diseases, and environmental factors. By identifying the cause of yellowing, you can take appropriate measures to prevent it and ensure the health of your cilantro plant.
