7 Super Effective Ways to Fix Snake Plant Fungus Problem (2021)

Snake plant fungus is one of the most well-known problems with indoor plants of this type. These plants can be infected by a wide variety of fungus, among them:

  • Red spots
  • Brown spots
  • Yellow spots
  • White spots
  • Southern Blight

Please check out the following guide if you are experiencing any of the above issues.

Snake Plant Fungus Causes

The following are reasons why your snake plant catches fungus: 


The plant can certainly be weakened by overwatering, even though it does not cause fungus directly. Weak plants attract a lot of problems more quickly than strong ones. In order to avoid wasting your snake plant, it’s important to not neglect this purpose.

Infrequent Watering

How often do you water your snake plant? Unless it is addressed, it can weaken the plant’s system and attract more problems like this. Consequently, infrequent watering could also be the cause of snake plant fungus.


Generally speaking, Snake plants tolerate tough weather conditions quite well. However, if you expose the plant to such conditions for a long time, it might become weak. In terms of weather conditions, it applies to both sides of the temperature scale. In either case, too much cold, too much heat or too much humidity can harm the plant. Weakening plants can become hosts to many issues, including the common fungus problem.

Overusing Fertilizers

The purpose of fertilizer is to help your plants grow. Our concern is that too much fertilizer will result in amazing growth, which isn’t always the case. Well, that isn’t how things work! Plants will suffer negatively if they are overfertilized. This can even attract fungi and harmful bacteria due to the weakened immune system.

Companion Plants

Snake plants can also get fungus from a companion plant on the patio or in the living room, in addition to natural conditions. It is not at all surprising if your Snake plant gets this disease from another plant since these issues can easily be transferred from one to another. The plant could also be attracted to fungi by that. Now, let’s see how we can fix the fungal problem.

Snake Plant Fungus Treatment

As we proceed with the fixes, keep in mind that it’s not easy to eliminate this issue entirely. Trial and error will be the most effective way for you to determine which technique or method works best.

Take Out Affected Leaves 

You should remove the leaves of your snake plant if you see a fungal infection on them. On the leaves, it could be either a brown spot or a red spot. But removing the affected leaf from the plant seems to be the most effective way to handle the problem. By doing so, you will prevent the fungus from spreading throughout your plant.

Change the Soil

Snake plant fungus can be removed by removing the old soil and replacing it with new soil. The soil removed should not be used for any other plants. Such soil should be discarded completely as it could spread the same issue to other indoor plants. Besides that, you should also rinse the plant with water. The leaves and roots of the plant can be treated by removing the fungus. Once you have changed the soil of your snake plant, be sure to water it thoroughly. Fertilizing the plant is not necessary at the beginning. Plants can be observed for several weeks to see what they grow into. The fertilizer can be fed regularly if it looks good. Once the soil has been changed, it has to be placed in a place with good sunlight and airflow. These two factors are essential for preventing snake plant fungus from reappearing.

Maintain Airflow

Your plants’ growth is heavily dependent on airflow, as discussed above. Additionally, it keeps the leaves and stems of the plant dry. By keeping these parts dry, you are automatically preventing fungal growth on the surface of the plant. The bathroom tends to have high humidity levels, so you should avoid keeping plants there. Keep the plant as close to a well-lit area of the house as possible. The snake plant will also be cleaned of fungus issues when you use this product.

Getting Enough Sunlight

To ensure that the plant receives enough sunlight, you need to place it in a bright place. This is an indoor plant, but it would be great if you could provide it with at least some sunlight. I would recommend placing the snake plant where it can receive a few hours of morning sunlight.

Avoid Watering In the Evening

If you water plants in the evening, the ground will stay wet for an extended period of time.The plant can easily be infected by fungal growth, so that’s not a good sign for you.You can change the schedule if you have been watering the plant in the evenings.


When it comes to fungi issues on indoor plants, fungicides can be quite effective. In my opinion, however, they should not be overused.You may see some exciting results if you use them in moderate quantities.

Neem Oil

I love this one! Your indoor plants will benefit from using neem oil to prevent infections from fungus and bacteria. There are no adverse consequences for the plant and it works pretty much like magic. Try it out and see what happens. For optimum results, you can prepare a dilute mixture of Neem oil and spray it once a week. That said, here are 7 effective ways to get rid of snake plant fungus.
