Why Are Your Calathea Zebrina Plant Leaves Curling

Calathea zebrina plants are popular houseplants known for their striking striped leaves. However, if you notice your plant’s leaves curling, it can be a sign of several issues that need to be addressed. In this article, we will discuss the reasons why your calathea zebrina plant leaves may be curling and what you can do to fix it.

Overwatering

Overwatering is one of the most common reasons why calathea zebrina plant leaves curl. These plants prefer moist soil but can easily get waterlogged if overwatered. When the soil is too wet, it can lead to root rot, which causes the roots to die off and affects the plant’s ability to absorb water and nutrients.

To fix this issue, ensure that you are not watering your calathea zebrina plant too frequently. Allow the top layer of soil to dry out before watering again. Make sure the pot has proper drainage holes, and water only when the soil feels dry to touch.

Underwatering

Underwatering can also cause calathea zebrina plant leaves to curl. These plants need consistent moisture, and if they don’t receive enough water, their leaves will start to curl inwards. This is the plant’s way of reducing its surface area and preserving water.

To fix this issue, ensure that your calathea zebrina plant is receiving enough water. Water your plant once a week and ensure that the soil is moist but not waterlogged. You can also mist your plant’s leaves regularly to increase humidity levels.

Low Humidity

Calathea zebrina plants are native to rainforests and thrive in high humidity levels. If the air in your home is too dry, it can cause their leaves to curl up and brown around the edges.

To fix this issue, increase humidity levels around your calathea zebrina plant by placing a humidifier near it or placing a tray of water nearby. You can also mist its leaves regularly or group it with other plants to create a microclimate with higher humidity levels.

Temperature Stress

Calathea zebrina plants prefer warm temperatures between 18°C-27°C (65°F-80°F). Exposure to cold drafts or temperatures below 15°C (60°F) can stress the plant, causing its leaves to curl up.

To fix this issue, ensure that your calathea zebrina plant is placed in a warm location away from cold drafts or air conditioning vents. You can also cover it with a plastic bag or cloth during transport on colder days.

Pest Infestation

Pest infestations such as spider mites or thrips can also cause calathea zebrina plant leaves to curl up. These pests feed on the plant’s sap, causing damage to its leaves and affecting its ability to grow.

To fix this issue, identify and treat pest infestations promptly using organic pest control methods such as insecticidal soap or neem oil. You should also isolate any affected plants from other healthy ones to prevent further spread of pests.
