Why Are Your Angelonia Plant Leaves Turning Yellow:
Causes and Solutions

Angelonia plants are known for their beautiful, bright blooms and long-lasting flowers. However, if you have noticed your Angelonia plant leaves turning yellow, it may be a cause for concern. Yellowing leaves can be a sign of various issues that require attention to ensure your plants stay healthy and vibrant. In this article, we will discuss the causes of yellowing Angelonia plant leaves and provide solutions to help revive your plants.

Causes of Yellowing Angelonia Plant Leaves

Overwatering

One of the most common causes of yellowing Angelonia plant leaves is overwatering. When the roots are consistently soaked in water, they become waterlogged, causing root rot. As a result, the plant cannot absorb nutrients effectively, leading to yellowing leaves.

Underwatering

On the other hand, underwatering can also cause yellowing leaves. When an Angelonia plant is not watered enough, it becomes stressed and may drop its leaves to conserve water.

Nutrient Deficiencies

Yellowing leaves can also be a sign of nutrient deficiencies. For example, if your plants lack nitrogen, the lower leaves will turn yellow first. If the deficiency continues, it will spread to other leaves.

Pests and Diseases

Pests and diseases can also cause yellowing leaves on Angelonia plants. For instance, spider mites can suck sap from the leaves, causing them to turn yellow and eventually fall off. Similarly, fungal diseases such as powdery mildew can cause yellow spots on the leaves.

Solutions to Yellowing Angelonia Plant Leaves

Watering

If overwatering is the cause of yellowing Angelonia plant leaves, you need to adjust your watering habits. Allow the soil to dry out slightly before watering again. Ensure that the pot has adequate drainage holes to prevent waterlogging.

If underwatering is the problem, increase your watering frequency. Check the soil moisture level regularly to ensure that it is consistently moist but not waterlogged.

Nutrient Deficiencies

To address nutrient deficiencies in your plants, consider using a balanced fertilizer with equal amounts of nitrogen, phosphorus and potassium (NPK). Apply it according to the manufacturer’s instructions.

Pest and Disease Control

For pests such as spider mites, you can use insecticidal soap or neem oil spray to control them. Fungal diseases such as powdery mildew can be treated with fungicides.
