Why Are Your Calathea Zebra Plant Leaves Curling

Calathea Zebra plants are a popular choice for indoor houseplants. They are known for their delicate and vibrant foliage, which can add a touch of elegance to any room. However, if you notice that the leaves of your Calathea Zebra plant are curling, it could be a sign that something is not quite right. In this article, we will explore the reasons why your Calathea Zebra plant leaves may be curling and what you can do to fix the problem.

Root Causes of Curling Leaves in Calathea Zebra Plants

1. Watering Issues

Overwatering or underwatering can lead to curling leaves in Calathea Zebra plants. The roots of these plants are sensitive to water, and if they receive too much or too little, it can cause stress to the plant. Overwatering can lead to root rot, which can cause the leaves to curl and turn yellow. Underwatering, on the other hand, can cause the leaves to curl inward as a way of conserving water.

2. Low Humidity

Calathea Zebra plants are native to tropical regions and require high humidity levels to thrive. If the air in your home is dry, it can cause the leaves of your plant to curl and dry up. In addition, low humidity levels can lead to brown edges on the leaves.

3. Temperature Fluctuations

Calathea Zebra plants prefer warm temperatures between 65-85°F (18-29°C). If the temperature drops below 60°F (15°C), it can cause the leaves to curl and turn yellow. In addition, exposure to cold drafts or sudden temperature changes can also stress the plant and lead to curling leaves.

4. Pest Infestation

Pests such as spider mites, mealybugs, and scale insects can damage the foliage of your Calathea Zebra plant and cause the leaves to curl. These pests feed on the sap of the plant and can weaken it over time.

How to Fix Curling Leaves in Calathea Zebra Plants

1. Watering

To fix curling leaves caused by overwatering, allow the soil to dry out completely before watering again. Make sure that your pot has drainage holes and that excess water is able to drain out. To fix curling leaves caused by underwatering, water your plant thoroughly until water runs out of the drainage holes.

2. Humidity

To increase humidity levels around your Calathea Zebra plant, you can place a humidifier nearby or group it with other plants to create a microclimate. You can also mist your plant regularly or place a tray of water near it to increase moisture in the air.

3. Temperature

To prevent temperature fluctuations from affecting your Calathea Zebra plant, make sure that it is not placed near cold drafts or heating vents. Keep it in a warm area with consistent temperatures between 65-85°F (18-29°C).

4. Pest Control

To get rid of pests on your Calathea Zebra plant, you can use insecticidal soap or neem oil spray. These products are safe for plants and will help kill off any unwanted pests.
