Why Are My Chamomile Plant Leaves Turning Yellow?

Updated: June 30, 2022

Chamomile is a beautiful and fragrant herb that has been used for centuries for its medicinal properties. It is also a popular plant to grow in gardens, but sometimes chamomile plants can experience problems, such as yellowing leaves. If you are experiencing this problem with your chamomile plant, don’t worry, there are several reasons why this might be happening and solutions to fix the issue.

Reasons for Yellowing Leaves in Chamomile Plants


One of the most common reasons for yellowing leaves in chamomile plants is overwatering. Chamomile plants require well-draining soil and should not be watered excessively. Overwatering can lead to root rot, which can cause the leaves to turn yellow and eventually die.


On the other hand, underwatering can also lead to yellowing leaves. Chamomile plants need regular watering, especially during hot and dry weather conditions. If the soil becomes too dry, the leaves will start to wilt and turn yellow.

Nutrient Deficiency

Yellowing leaves can also indicate a nutrient deficiency in the soil. Chamomile plants require a balanced amount of nutrients, including nitrogen, phosphorus, and potassium. A lack of these essential nutrients can cause the leaves to turn yellow.

Pests and Diseases

Pests and diseases can also cause yellowing leaves in chamomile plants. Aphids and spider mites are common pests that attack chamomile plants, causing damage to the foliage. Diseases such as powdery mildew and botrytis can also cause yellowing of the leaves.

Solutions for Yellowing Leaves in Chamomile Plants


Proper watering is essential for healthy chamomile plants. Ensure that the soil is well-draining and water the plant regularly during dry weather conditions. Avoid overwatering, as this can lead to root rot.


If your chamomile plant is experiencing nutrient deficiencies, you can fertilize it with a balanced fertilizer. Follow the instructions on the packaging and ensure that you do not over-fertilize, as this can cause damage to the plant.

Pests and Diseases

If your chamomile plant is affected by pests or diseases, it is essential to take action immediately. You can use insecticidal soap or neem oil to control pests such as aphids and spider mites. For diseases such as powdery mildew, you can use a fungicide to prevent further damage to the plant.
