12 Causes of Brown Spots on Pothos (And Treatment)

Below are the causes of the Brown Spots on Pothos and also the ways that can help you in treating these issues. They are as follows:

Causes of Brown Spots on Pothos

Phytophthora Root Rot

Phytophthora root rot is a common problem for pothos plants. One of the Causes of Brown Spots on Pothos is root rot. This disease is caused by a water mold that attacks the plant’s roots, causing them to rot.

The fungus can also spread to the stem and leaves of the plant, causing them to turn brown and wilt. Phytophthora root rot is most often caused by overwatering or flooding, but it can also be caused by poorly drained soil or exposure to high humidity.

Treatment for this disease includes removing affected leaves and stems, improving drainage, and increasing air circulation around the plant.

Direct Sun Exposure

If you notice brown spots on your pothos leaves, it is likely that the plant is getting too much direct sun exposure. It is one of the other Causes of Brown Spots on Pothos.

While pothos plants can tolerate some direct sun, too much can cause the leaves to become scorched or burnt.

If you see brown spots and/or leaves that are starting to turn yellow or brown, move your pothos plant to a location with less direct sunlight.

Lack Of Humidity And Harsh Drafts

If you notice brown spots on your pothos leaves, it is most likely due to a lack of humidity and/or harsh drafts. One of the Causes of Brown Spots on Pothos is the lack of humidity. Pothos plants thrive in humid environments and need high humidity to prevent their leaves from drying out and turning brown.

If you live in a dry climate or your home has central heating or air conditioning, consider investing in a humidifier to increase the humidity around your pothos plant. You can also try misting your plant with water daily or placing it on a pebble tray filled with water.

In addition to increasing the humidity, you also need to make sure that your pothos plant is not exposed to drafts from doors or windows. These drafts can cause the leaves to dry out and turn brown. If you suspect that drafts are the cause of the brown spots, move your plant to a different location in your home where it will be protected from drafts.

Lack of lighting

Brown spots on pothos leaves are most commonly caused by too little light. Pothos is a low-light plant, so it does not need direct sunlight to thrive.

However, too little indirect light can cause the leaves to develop brown spots. If you notice brown spots on your pothos leaves, try moving the plant to a location with some light.

Brown spots can also be caused by the lack of sunlight. If your pothos is in a location where it gets direct sunlight, try moving it to a shadier spot. If the brown spots are severe, you may need to cut off the affected leaves.

Pests

Pests and disease can also cause brown spots on pothos leaves. Insects like mealybugs and spider mites can suck the nutrients out of plants, causing the leaves to turn brown and die. One of the Causes of Brown Spots on Pothos is the Pests. Powdery mildew is a type of fungus that appears as white powder on the leaves of plants.

It can also cause brown spotting on pothos leaves. If you think pests or diseases are to blame for the brown spots on your pothos, treat the plant with an insecticide or fungicide according to the label directions.

Sunburn

Sunburn is a common cause of brown spots on pothos leaves. If your plant is in a spot that gets direct sunlight for more than a few hours each day, it may be susceptible to sunburn. Brown spots will appear on the leaves as they scorch from the sun’s rays.

To prevent sunburn, move your pothos to a spot that gets indirect light or filtered sunlight. If you think your pothos is getting too much sun, move it to a shadier spot. If the brown spots are small and dry, they will eventually fall off on their own. If the brown spots are large and wet, you can cut them off with a sharp knife or scissors.

Another type of fungus that can appear on pothos is black sooty mold. This fungus is usually caused by aphids or mealybugs feeding on the plant.
