The Paradise Plant, scientifically known as Monstera deliciosa, is a popular houseplant known for its lush green leaves and unique perforations. However, sometimes these leaves can develop a curling pattern that can be concerning for plant owners. Understanding the causes behind this leaf curling can help diagnose and treat the issue effectively.

Overwatering and Poor Drainage

One of the most common causes of leaf curling in Paradise Plants is overwatering. These plants prefer a well-draining soil mix that allows water to pass through easily, preventing waterlogged roots. When the roots are constantly saturated, they become deprived of oxygen, leading to stress and curling of the leaves.

To avoid overwatering, it is essential to allow the top layer of soil to dry out before watering again. Additionally, ensure that the pot has proper drainage holes to prevent water retention. If the plant is already showing signs of leaf curling due to overwatering, adjusting the watering schedule and repotting it in a well-draining mix can help alleviate the issue.

Underwatering and Low Humidity

On the other hand, underwatering can also cause leaf curling in Paradise Plants. When these plants do not receive enough water, they struggle to maintain their turgidity, resulting in curled leaves. Additionally, low humidity levels can exacerbate this problem.

To address underwatering, it is important to regularly check the moisture level of the soil by sticking a finger into the top inch or two. If it feels dry, it’s time to water the plant. Furthermore, increasing humidity around the plant by misting the leaves or placing a humidifier nearby can prevent leaf curling caused by dry air.

Temperature and Environmental Factors

Paradise Plants thrive in warm temperatures ranging from 65°F to 85°F (18°C to 29°C). Exposure to extreme temperatures, especially cold drafts or sudden temperature fluctuations, can cause stress to the plant and result in curled leaves.

To avoid temperature-related leaf curling, it is crucial to place the plant in a location with consistent temperatures away from drafts or vents. Avoid placing it near windows during winter as the cold air can damage the leaves. Maintaining a stable environment will help prevent leaf curling caused by temperature fluctuations.

Pests and Diseases

Pests and diseases can also contribute to leaf curling in Paradise Plants. Common pests that affect these plants include spider mites, aphids, and mealybugs. These pests feed on the plant’s sap, causing stress and curling of the leaves.

Regularly inspecting the leaves for any signs of pests, such as webs or tiny insects, is important for early detection. If pests are present, they can be treated using organic insecticidal soaps or horticultural oils. Additionally, practicing good plant hygiene by cleaning the leaves regularly and avoiding overcrowding can help prevent infestations.

Diseases, such as root rot or fungal infections, can also lead to leaf curling. These issues are often caused by overwatering, poor drainage, or unsanitary conditions. To prevent diseases, it is essential to provide proper watering and ensure the plant’s environment is clean and well-ventilated.

Nutritional Deficiencies

Leaf curling can also be a sign of nutritional deficiencies in Paradise Plants. Lack of essential nutrients like magnesium, iron, or potassium can cause the leaves to curl and become discolored.

To address nutritional deficiencies, it is important to provide the plant with a balanced fertilizer specifically formulated for tropical plants. Regularly feeding the plant during its active growing season will ensure it receives all the necessary nutrients for healthy growth and prevent leaf curling due to deficiencies.

Genetic Factors

In some cases, leaf curling in Paradise Plants can be attributed to genetic factors. Some varieties or cultivars may naturally have leaves that curl or twist as part of their growth pattern. While this may not indicate any underlying issues, it is essential to differentiate between genetic leaf curling and curling caused by environmental factors or diseases.

Researching the specific variety of Paradise Plant and consulting with experts can help determine whether the leaf curling is genetic or a result of other factors. Understanding the plant’s natural growth habits will provide valuable insights into its care requirements.


Leaf curling in Paradise Plants can be caused by various factors, including overwatering, underwatering, temperature fluctuations, pests, diseases, nutritional deficiencies, or genetic factors. By identifying the root cause of the leaf curling and implementing appropriate care measures, plant owners can ensure their Paradise Plants thrive with healthy, vibrant leaves. Regular monitoring, proper watering techniques, providing adequate humidity, and addressing any pest or disease issues promptly will contribute to the overall well-being of these stunning houseplants.
