Spider plants are popular houseplants due to their hardiness and attractive foliage. They are known for their long, thin leaves that grow from a central rosette and produce small, white flowers during the summer months. However, sometimes the leaves of spider plants can become curly, which can be a cause for concern for plant owners. In this article, we will explore the reasons why spider plant leaves curl and what you can do to prevent it from happening.


One of the most common reasons for spider plant leaves to curl is overwatering. When spider plants are overwatered, the roots become saturated with water, making it difficult for the plant to absorb nutrients. This can cause the leaves to become limp and curl up. Overwatering can also lead to root rot, which is a serious condition that can kill your spider plant.


On the other hand, underwatering your spider plant can also cause its leaves to curl. When spider plants don’t receive enough water, they begin to conserve moisture by curling their leaves inward. This helps the plant retain as much water as possible until it receives more.


Another factor that can cause spider plant leaves to curl is inadequate lighting. Spider plants require bright but indirect light to thrive. If your spider plant is not getting enough light, its leaves may curl up as a way of protecting themselves from too much sun exposure.

Temperature and Humidity

Spider plants prefer warm temperatures between 60°F and 75°F and high humidity levels between 40% and 60%. If the temperature or humidity level in your home is too low, your spider plant may start to curl its leaves. This is because low humidity levels can cause the leaves to lose moisture quickly, leading to curling.


Finally, pests can also cause spider plant leaves to curl. Spider mites, mealybugs, and scale insects are common pests that can infest spider plants. These pests feed on the leaves of the plant, causing damage that can lead to curling.

How to Prevent Spider Plant Leaves from Curling

To prevent spider plant leaves from curling, it’s important to provide your plant with the right conditions. Here are some tips to help you keep your spider plant healthy and free from curling:

  • Water your spider plant only when the top inch of soil is dry.
  • Make sure your spider plant is getting enough bright, indirect light.
  • Keep your spider plant in a warm, humid environment.
  • Regularly inspect your spider plant for signs of pests and treat them promptly if you find any.

By following these tips, you can help your spider plant stay healthy and avoid curling leaves.


Why are my spider plant leaves turning brown?

Brown leaves on a spider plant can be caused by a variety of factors, including overwatering, underwatering, low humidity levels, or pest infestations. It’s important to identify the cause of the problem to determine the best course of action.

Can I cut off the curled leaves?

Yes, you can cut off curled leaves from your spider plant. However, it’s important to identify and address the underlying cause of the curling to prevent it from happening again in the future.

How often should I water my spider plant?

Spider plants should be watered only when the top inch of soil is dry. This can vary depending on factors such as the temperature and humidity levels in your home. In general, spider plants should be watered about once a week.
