Why Are Your Calathea Rattlesnake Plant Leaves Curling

Calathea Rattlesnake plants, also known as Calathea lancifolia, are a popular houseplant because of their unique foliage. The leaves of this plant are long and slim, with dark green stripes that resemble the markings of a rattlesnake. However, one common problem that many Calathea Rattlesnake plant owners face is the curling of their leaves.

If your Calathea Rattlesnake plant leaves are curling, it could be due to a variety of reasons. In this article, we will explore the causes of curled leaves and provide tips on how to fix the issue.

Causes of Curling Leaves

Underwatering or Overwatering

One of the most common reasons for curling leaves in Calathea Rattlesnake plants is overwatering or underwatering. If the soil is too dry or too wet, it can cause stress to the plant, which leads to curled leaves.

To avoid this issue, make sure to water your plant regularly but not excessively. Allow the soil to dry out slightly between waterings, and avoid letting the plant sit in standing water.

Low Humidity Levels

Calathea Rattlesnake plants thrive in high humidity levels. If the air is too dry, it can cause stress to the plant and lead to curled leaves. You can increase humidity levels by misting the plant regularly or placing a humidifier near it.

Temperature Fluctuations

Another reason for curled leaves in Calathea Rattlesnake plants is temperature fluctuations. These plants prefer warm temperatures between 60-85°F (15-29°C). If the temperature drops below this range or fluctuates frequently, it can cause stress to the plant and lead to curled leaves.

Pest Infestation

Pests such as spider mites and mealybugs can also cause curled leaves in Calathea Rattlesnake plants. These pests feed on the plant’s sap and weaken its structure, leading to curled leaves.

Inspect your plant regularly for signs of pest infestation such as webbing or sticky residue on the leaves. If you notice any pests, treat them immediately with an insecticidal soap or neem oil to prevent further damage.

How to Fix Curled Leaves

If your Calathea Rattlesnake plant leaves are curling, there are several steps you can take to fix the issue:

Watering

Check the soil moisture levels by sticking your finger into the soil up to your knuckle. If the soil feels dry, water your plant thoroughly until water drains out of the bottom of the pot. If the soil feels wet, allow it to dry out slightly before watering again.

Humidity

Increase humidity levels around your plant by misting it regularly or placing a humidifier nearby. You can also place a tray of water near the plant to increase humidity levels.

Temperature

Ensure that your plant is in a location with consistent temperatures between 60-85°F (15-29°C). Avoid placing it near drafty windows or air conditioning vents.

Pest Control

Inspect your plant regularly for signs of pests and treat them immediately if you notice any infestation. Use insecticidal soap or neem oil to control spider mites and mealybugs.
