Why Does my Fernwood Snake Plant Have Brown Spots?

Updated: December 24, 2022

Snake plants are well-known for their hardiness and resilience, which makes them a popular choice among plant enthusiasts. However, even the most robust plants can sometimes fall victim to common problems like brown spots. If you’re noticing brown spots on your Fernwood Snake plant, don’t panic! This article will guide you through the reasons behind this issue and how to fix it.


Overwatering is the most common cause of brown spots on snake plants. When the soil is excessively damp, the roots can become waterlogged, leading to root rot. This condition restricts the plant’s ability to absorb nutrients and water from the soil, resulting in brown spots on the leaves.

To avoid overwatering your Fernwood Snake plant, ensure that the soil is well-draining, and water only when necessary. You can check if the soil is dry by sticking your finger an inch deep into the soil. If it feels dry, then it’s time to water.


Underwatering can also cause brown spots on snake plants. When a plant is not getting enough water, it will start to shed leaves to conserve moisture. The remaining leaves may develop brown tips or spots as a result of dehydration.

To prevent underwatering your Fernwood Snake plant, ensure that you water it regularly. However, don’t water too frequently as this can lead to overwatering.

Low Humidity

Fernwood Snake plants thrive in humid environments. Low humidity levels can cause the leaves to turn brown and dry out. This condition is more prevalent during winter when indoor heating systems can reduce humidity levels.

To increase humidity levels around your Fernwood Snake plant, you can mist it regularly or use a humidifier. Alternatively, you can group several plants together to create a microclimate of higher humidity.

Pest Infestation

Pests such as spider mites and mealybugs can cause brown spots on snake plant leaves. These pests suck the sap from the leaves, leading to discoloration and a weakened plant.

To get rid of pests on your Fernwood Snake plant, use an insecticidal soap or neem oil. You can also isolate the plant to prevent the infestation from spreading to other plants.


Finally, diseases such as fungal infections can cause brown spots on snake plants. Fungi thrive in damp environments, so overwatering and high humidity levels can create a conducive environment for the disease to spread.

To treat fungal infections, use a fungicide spray and ensure that the plant is well-ventilated to prevent moisture buildup.


1. Can I remove brown spots from my Fernwood Snake plant?

Yes, you can remove brown spots by cutting off the affected leaves using sterilized pruning shears. This prevents the spread of the disease to other parts of the plant.

2. How often should I water my Fernwood Snake plant?

Water your Fernwood Snake plant once a week or when the soil feels dry an inch deep.

3. Can I fertilize my Fernwood Snake plant?

Yes, you can fertilize your Fernwood Snake plant once a month during the growing season using a balanced fertilizer. However, avoid fertilizing during winter when the plant is dormant.

In summary, brown spots on your Fernwood Snake plant can be caused by overwatering, underwatering, low humidity levels, pest infestations, or diseases. By identifying the cause of the problem and taking corrective measures, you can restore your Fernwood Snake plant’s health and beauty.
