Why Does my Dwarf Snake Plant Have Brown Spots?

Updated: December 6, 2022

Dwarf snake plants, also known as Sansevieria trifasciata, are a popular indoor plant choice due to their low maintenance and air-purifying properties. However, if you’ve noticed brown spots on your dwarf snake plant’s leaves, it can be a cause for concern. In this article, we’ll explore the common reasons why your dwarf snake plant may have brown spots and how to fix them.

Overwatering

Overwatering is the most common cause of brown spots on dwarf snake plants. These plants are drought-tolerant and only require watering every two to three weeks. When they receive too much water, the roots can become waterlogged and lead to root rot. This condition causes brown spots to appear on the leaves, which can spread quickly if not addressed promptly.

To fix this problem, ensure that you’re not watering your plant too often. Allow the soil to dry out completely before watering it again. Check the soil moisture level by inserting your finger about an inch deep into the soil. If the soil feels moist, wait a few more days before watering again.

Underwatering

Underwatering can also cause brown spots on dwarf snake plants. When these plants are not watered enough, they will begin to droop and develop brown spots on their leaves. This is because they require a consistent amount of moisture to thrive.

To fix this problem, ensure that you’re watering your plant regularly. Stick to a schedule of watering every two to three weeks or when the soil feels dry to the touch. You can also mist your plant’s leaves with water to provide additional moisture.

Low Humidity

Low humidity levels can cause brown spots on dwarf snake plants as well. These plants thrive in environments with high humidity levels and can suffer from dehydration if the air is too dry. This can lead to brown spots on the leaves and cause the plant to wilt.

To fix this problem, increase the humidity levels around your plant. You can do this by placing a humidifier near your plant or by misting its leaves with water. You can also place a tray of water near your plant, which will increase the surrounding air’s moisture content.

Pests

Pests, such as spider mites and mealybugs, can cause brown spots on dwarf snake plants. These insects feed on the plant’s sap, causing it to turn brown and die.

To fix this problem, inspect your plant regularly for signs of pests. If you notice any, remove them by wiping the leaves with a damp cloth or spraying the plant with insecticidal soap.

Fungal Infections

Fungal infections, such as anthracnose and leaf spot, can cause brown spots on dwarf snake plants. These infections are caused by fungi that thrive in warm and humid environments.

To fix this problem, remove any affected leaves and improve air circulation around your plant. Ensure that your plant is not overcrowded and receives plenty of sunlight. You can also treat your plant with a fungicide to prevent the spread of the infection.
