What Causes English Ivy Plant Leaves to Curl?

Updated: March 25, 2022

English Ivy is a popular houseplant that is loved for its visual appeal and easy maintenance. However, at times, the leaves of the plant may start to curl, which can be a cause for concern for many gardeners. In this article, we will explore the various reasons why English Ivy plant leaves may curl.


Overwatering is one of the most common causes of curling leaves in English Ivy plants. When the soil is waterlogged, it restricts the flow of oxygen to the roots, which can lead to several problems, including curled leaves. This is because the roots are not able to take up nutrients and water effectively, leading to stress in the plant.


Underwatering is another common cause of leaf curl in English Ivy plants. When the soil dries out too much, it can cause the leaves to curl as a way of conserving moisture. The plant may also start to wilt and show signs of stress.

Low Humidity

English Ivy plants require high humidity levels to thrive. If the air in your home or office is too dry, it can cause the leaves to curl up as a way of conserving moisture. This is especially common during winter when indoor heating systems can dry out the air.


Pests like spider mites and aphids can also cause English Ivy plant leaves to curl. These pests feed on the sap in the leaves, which can cause them to curl and become distorted. It’s important to check your plants regularly for any signs of pests and take appropriate action if you notice any.


Diseases like bacterial leaf spot and powdery mildew can also cause leaf curl in English Ivy plants. These diseases are often caused by poor growing conditions like overwatering and low humidity levels. If you suspect that your plant has a disease, it’s important to take action quickly to prevent it from spreading.

Nutrient Deficiencies

Nutrient deficiencies can also cause English Ivy plant leaves to curl. For example, a lack of nitrogen can cause the leaves to turn yellow and curl, while a lack of magnesium can cause the edges of the leaves to curl up.

Temperature Stress

Extreme temperatures, both hot and cold, can cause stress in English Ivy plants, which can lead to leaf curl. It’s important to keep your plants away from drafty windows and doors and maintain a consistent temperature to prevent stress.

Overall, there are several reasons why English Ivy plant leaves may curl. By understanding the causes, you can take appropriate action to prevent it from happening.

Can I mist my English Ivy plant to increase humidity levels?

Yes, misting your English Ivy plant is a great way to increase humidity levels. You can also place a humidifier near the plant or set it on a tray of pebbles filled with water.

How do I treat pests on my English Ivy plant?

You can treat pests on your English Ivy plant by using an insecticidal soap or neem oil. It’s important to follow the instructions carefully and treat your plant regularly until the infestation is gone.
