What Causes Dragons Tongue Plant Leaves to Curl?

Dragon’s Tongue plant, also known as Dracaena marginata, is a popular houseplant known for its striking appearance and air-purifying abilities. However, many people may notice that the leaves of this plant may curl, which can be a cause for concern. In this article, we will explore the common causes of curled leaves in Dragon’s Tongue plants and what you can do to fix it.

Common Causes of Curled Leaves in Dragon’s Tongue Plants

1. Overwatering

Overwatering is one of the most common causes of curled leaves in Dragon’s Tongue plants. When the roots are constantly submerged in water, it can lead to root rot and other fungal diseases that can affect the plant’s overall health. This can cause the leaves to curl and turn yellow or brown.

2. Underwatering

On the other hand, underwatering can also cause the leaves of your Dragon’s Tongue plant to curl. When the plant doesn’t receive enough water, it will start to conserve its resources by curling its leaves to reduce surface area and prevent water loss. This can make the plant look wilted and unhealthy.

3. Low Humidity

Dragon’s Tongue plants prefer high humidity levels, so when they are exposed to dry air or low humidity levels, they may start to curl their leaves. This is because the plant is trying to conserve moisture by reducing its leaf surface area.

4. Temperature Stress

Temperature stress can also cause the leaves of your Dragon’s Tongue plant to curl. When the plant is exposed to extreme temperatures, either hot or cold, it can lead to leaf curling and other damage. Make sure to keep your Dragon’s Tongue plant away from cold drafts and direct sunlight.

5. Pest Infestation

Finally, pest infestation can also cause the leaves of your Dragon’s Tongue plant to curl. Spider mites, mealybugs, and scale insects are common pests that can affect this plant. They can suck the sap from the leaves, which can cause them to curl and turn yellow or brown.
