The snake plant would be a serious candidate for the title of the hardest houseplant. Snake plants can endure low light, dehydration, and insects. However, even the most resistant plants can contract illnesses that hurt their growth and attractiveness.
Brown spots are among the leaf diseases that affect snake plants most frequently. Brown patches on snake plants are often caused by fungi, bugs, and inadequate watering. Extreme sunlight exposure, cold, and fertilizer overuse can worsen this issue. Apply a fungicide with a copper base and a natural or synthetic pesticide to eliminate the insects.
This post will discuss ways to prevent diseases from spreading to your snake plant and why brown patches appear on the plant.
What Factors Cause Brown Spots On Snake Plants?
Many things can cause brown spots to appear on your snake plant. Poor treatment is the root cause of improper irrigation or fungus problems.
Snake plants can develop reddish-brown lesions on their leaves due to fungi like southern blight and red leaf spots. Brown areas that are soft and squishy will develop and start to secrete a sticky brown liquid.
Another infection that results in brown, wet spots on plant leaves is rust, while bacterial leaf spots are another.
In more detail, let’s examine the three fungi that could be the source of your snake plant’s browning leaves.
A Red Leaf Spot
A red leaf spot is to blame if your snake plant develops crimson or brownish-red blotches. High humidity levels and warm temperatures encourage the formation and spread of this disease. Snake plants with the Southern Blight fungus infestation are displaying brown patches.

As the snake plant assaults the root system, it will start to turn yellow and brown. You risk losing your snake plant if you don’t take action.
Snake plants may not be susceptible to this, but it can still result in rust-like brown blotches on the leaves. Rust is caused by fungi of the Heterobasidiomycetes subclass infecting living plant tissues, especially leaves. Rust fungi migrate from one plant to another after absorbing the sap since they do not feed on decaying organic substances.
Snake plant rust frequently starts on the leaves first and can destroy the entire plant if it is not properly treated.
What Best Ways to Avoid Fungal Issues?

Like red leaf spots, rusts can be treated by removing the affected component. To stop the rust from spreading further, you should also eliminate any diseased leaves still on the ground and restrict your contact with water.
Treatment for Bacterial Leaf Spot
This disease manifests as water-soaked spots that eventually turn brown and is brought on by Pseudomonas spp. or Xanthomonas spp. There is no recommended pharmacological therapy for this illness. The greatest remedy has been mechanical therapy or removing the affected area.
Because the illness can be transferred by splashes of water and damp air, it is best to use caution when watering contaminated clothing.
Infestation of pests
Mealybug and spider mite infestations can affect snake plants. These pests eat the sap from the leaves, which causes stress and the development of brown patches.
