What Causes Earth Star Plant Leaves to Curl?

Updated: September 23, 2022

Earth star plants are stunning, low-maintenance houseplants that require little attention to thrive. They have broad, paddle-shaped leaves that often curl inward. While this can be a natural occurrence, sometimes it can indicate an issue with the plant’s environment or care. In this article, we’ll explore some of the reasons why earth star plant leaves curl and what you can do to prevent it.

Natural Causes of Leaf Curling

Phototropism

Phototropism is the growth movement of plants in response to light. Most plants grow towards the light source, but earth star plants have a unique growth pattern. Their leaves grow outward from the center of the plant and curl inward towards the soil. This is a natural response to gravity and helps protect the plant’s delicate growing tips from damage.

Drought Stress

Earth star plants are native to arid regions and are adapted to survive long periods without water. During times of drought, their leaves will curl inward to reduce the amount of surface area exposed to the sun and conserve moisture. If your earth star plant is displaying curled leaves, it may simply be in need of watering.

Environmental Causes of Leaf Curling

Low Humidity

Earth star plants prefer high humidity levels between 50-60%. If the air in your home is too dry, their leaves may start to curl inward. To increase humidity around your plant, you can mist it regularly or place a humidifier nearby.

Temperature Stress

Earth star plants thrive in temperatures between 60-75°F (15-24°C). If they are exposed to temperatures outside of this range, their leaves may curl inward as a sign of stress. Keep your plant away from air conditioning units, heating vents, and drafty windows.

Care-Related Causes of Leaf Curling

Overwatering

While earth star plants are adapted to survive drought conditions, they are susceptible to root rot if overwatered. If the soil around their roots is constantly saturated, their leaves may curl inward and turn brown. To prevent overwatering, allow the soil to dry out between waterings.

Underwatering

On the other hand, if your earth star plant isn’t receiving enough water, its leaves may curl inward as a sign of stress. To prevent underwatering, make sure to water your plant thoroughly whenever the soil feels dry to the touch.
