Are you wondering why does my snake plant have brown spots? If so, then you’re not alone. More and more people who have the popular low-maintenance houseplant in their homes are asking this exact question. 

While the cause isn’t always immediately clear, what is known is that often times it can be addressed with a few simple changes to your care routine. 

In this post, we will take an in-depth look at why brown spots may appear on your snake plant and how best to remedy them.


What causes brown spots on snake plants?

Brown spots on Snake Plants can be caused by a variety of factors, including environmental stress, inadequate watering practices, pest infestations, nutrient deficiencies, and fungal diseases. 


Environmental stress 

This is one of the most common causes of browning leaves on Snake Plants. 

This type of stress can occur due to excessive light exposure, extreme temperatures, low humidity levels, and improper ventilation. 

To prevent this type of damage from occurring, ensure that your plant is placed in an area with plenty of indirect sunlight and that the temperature remains between 65-75 degrees F. 

In addition, increase humidity levels around your plant and make sure that the area is well-ventilated. 


Inadequate watering practices 

Generally speaking, it is important to water your plants thoroughly. But not excessively as this can lead to root rot or other issues. 

Be sure to let your soil dry out between waterings and avoid saturating the roots.


Pest infestations 

Common pests include mealybugs and spider mites which feed off the sap inside leaves causing them to become discolored or damaged over time. 

To prevent this problem from occurring, regularly inspect your plant for signs of pests and spray with an appropriate insecticide if necessary. 


Nutrient deficiencies 

This can lead to discoloration in Snake Plants as certain nutrients are required for healthy growth and development. 

If a deficiency occurs, it may show up as yellowing or browning of the leaves. 

This may indicate that the plant needs more fertilizer or iron supplements, such as iron chelate products.


Fungal diseases 

It may also be responsible for brown spots on Snake Plants which often appear as dark patches or spots on foliage surfaces. 

The best way to combat this type of disease is to reduce the moisture content around the plant and prune it properly. Or relocate them to a place with better air circulation.

In addition, the use of fungicides may help control further spread if necessary.

However, be sure to check any labels prior to use for safety precautions for use around edible plants.


Should you cut brown spots off snake plant?

It is not recommended to simply cut off brown spots, as this will not solve the underlying problem causing them. 

If you are unsure of the cause of your Snake Plant’s brown spots, it is best to diagnose and treat the issue before pruning. 

If it is a pest or disease problem, treating it directly can prevent further damage and scarring. 

Pruning may help improve the appearance of your Snake Plant. But cutting off the affected leaves could spread whatever caused the issue in the first place and lead to further damage.



This article has provided some insight into why your snake plants have brown spots. So you can take action accordingly and make sure your plants remain healthy. 

Naturally speaking, prevention is better than cure. Avoid growing your snake plants near windows, use soil with an appropriate drainage rate, and feed them properly, so that they can last for many years.
