What causes brown spots on pothos?

Too much light

One of the most common problems that pothos owners face is brown spots on the leaves.

There are several possible causes for this, but the most likely culprit is direct sunlight.

Pothos plants are native to tropical rainforests, where they grow in the dappled light beneath the canopy of taller trees. They are not adapted to bright, direct sunlight, and their leaves will often scorch when exposed to too much light.

If you notice brown spots on your pothos leaves, try moving it to a location with filtered light or dappled shade. In most cases, this will solve the problem.

Overfertilization or under fertilization

The cause of brown spots on pothos can vary depending on the particular situation. In general, one of the most common causes of brown spots on this plant is insufficient or excessive fertilization.

If your pothos is not getting enough nutrients, for example, it may begin to deteriorate and develop patches or lesions that appear brownish.

On the other hand, if you are over-feeding your plant with too much fertilizer, this can also lead to problems such as the browning and curling of the pothos leaves.

To prevent and treat these issues, be sure to monitor your plant’s growth carefully and use fertilizers wisely according to manufacturer recommendations.

Pests, diseases and infestations:

Brown spots on a pothos plant are usually caused by one of three things: pests, diseases, or infestations.

Pests, such as aphids and spider mites, can damage the leaves of a pothos plant and cause brown spots.

Diseases, such as powdery mildew and leaf spot, can also cause brown spots.

Finally, infestations, such as mealybugs and scale insects, can suck the nutrients out of the leaves, causing them to turn brown.

To Treat brown spots caused by pests or diseases, it is important to identify the specific problem and then choose the appropriate treatment.

For example, if the brown spots are caused by spider mites, you may need to use a pesticide. If the brown spots are caused by powdery mildew, you may need to use a fungicide. If the brown spots are caused by scale insects, you may need to use an insecticide.

In most cases, brown spots caused by infestations can be treated with a systemic insecticide.

Systemic insecticides are absorbed by the roots and then travel up through the plant to kill the insects feeding on the leaves. This type of insecticide is very effective at treating infestations and preventing brown spots.


brown spots on the leaves are a common problem that can occur due to a number of different factors.

One of the most common causes of brown spots is underwatering. When the plant doesn’t receive enough water, the leaves will begin to brown and dry out.

This is often exacerbated by low humidity levels, which can cause the leaves to lose even more moisture. If you notice brown spots on your pothos, check the soil to see if it is dry.

If it is, water your plant thoroughly and mist the leaves with water regularly to raise the humidity levels. With proper care, your pothos should soon recover from its brown spots.

There are several possible causes of this problem, but one of the most likely culprits is low humidity. Pothos thrives in high humidity environments, so if the air in your home is too dry, it can cause the leaves to turn brown.

To fix this problem, you can try increasing the humidity around your Pothos by placing it on a pebble tray or using a humidifier. The ideal humidity levels for pothos are 20-30%.

Phytophthora Root Rot

Phytophthora root rot is a disease that can affect pothos plants, causing brown spots and other symptoms along the surface of the leaf.

This disease is especially common among cuttings of pothos, and it can be easily spread through stagnant water in the root zone or high levels of moisture in the air.

As the disease progresses, it can be seen moving from the petiole to near the leaf base, and eventually spreading to the leaf tip.

The best way to prevent and treat this condition is to isolate any infected plants, taking care to provide ample space, well-drained soil, and proper watering techniques.

You might have to kill the plant to save your other plants from getting this disease.

Natural Browning

As your pothos matures, it will go through a process called natural browning.

This is when the leaves of the plant turn brown and dry out, eventually falling off.

Natural browning is a normal part of the plant’s life cycle and is nothing to be concerned about.

However, if your pothos is showing signs of other problems, such as pest infestations or disease, this might be exacerbating the problem and should be addressed.

Water quality:

Pothos are some of the hardiest plants around, making them perfect for those who are new to gardening or who may not have easy access to high-quality water.

These versatile plants can tolerate both tap water and well water, but it is important to be aware of the levels of chlorine, salts, and fluoride in these two types of water.

If the tap water has very high chlorine levels, an accumulation in the plant can result in scorched-looking tissue along the margins, tips, and between veins.

However, with low chlorine levels and a proper fertilization routine, pothos can be healthy and beautiful for years to come.

So, if you want a low-maintenance plant that will thrive despite potential challenges from your tap water supply, consider adding pothos to your home or garden today!

How to treat brown spots on pothos

Care routine:

Brown spots on pothos can be frustrating, but there are a few things you can do to care for your plant and prevent further damage.

First, make sure you’re only watering it once a week – any more than that and you risk overwatering, which can lead to brown spots.

Second, check the top of the soil every day to see how moist it is; if it’s too dry, give your pothos a little extra water.

Lastly, only feed your plant during the spring and summer months – too much fertilizer can burn the leaves and cause brown spots.

Surroundings of the plants:

Brown spots on pothos can be caused by a variety of factors, including too much sun, too little water, or pests. However, the most common cause of brown spots is low humidity.

Pothos thrive in humid environments, so it’s important to keep the humidity level around 20-30%.

If the air is too dry, the leaves will start to turn brown and eventually drop off. In addition to maintaining high humidity levels, it’s also important to keep the temperature between 70-90F.

Pothos prefer a warm environment, so if the temperature drops too low, the leaves will turn brown and die.

Lastly, pothos needs bright but indirect light to thrive. Too much sun will scorch the leaves, while too little sun will cause the leaves to turn yellow.

Infestation, pests and diseases

If you notice any signs of browning on your pothos plants due to pest infestation or disease, it is important to take action quickly to prevent further damage from occurring.

The first step is to go through your plants carefully and look for any insects or fungal growths.

If you spot any pests or mold spores, you should treat your plants with a natural pesticide or organic fungicide to eliminate them.

There are several ways to get rid of bugs on your pothos plant.

You can mix dish soap with water and cover your plant with it. The soap will not allow the bugs to stick to the surface.

Bug spray is another option. If you spray the plant, any bugs near it will die.

Rubbing alcohol is also a way to get rid of bugs. Just dip a cotton swab and rub it on the leaves.

If one plant is diseased, keep it away from all the others to stop it from spreading.

There are several ways to get rid of diseases on your pothos plants- one option is to use a fungicide. This will attack fungal infections before they grow.

Prune the leaves:

There are several different ways to treat brown spots on a pothos plant.

The most common treatment involves pruning the affected leaves, as this will prevent the fungus or bacteria from spreading to other parts of the plant.

Leaves that are significantly brown or dead should be cut off close to the stem, and any leaves that show early signs of browning (such as yellowing or wilting) should also be trimmed.

After pruning, it is important to dispose of the affected leaves in a way that will prevent the spread of disease, such as by putting them in a plastic bag and disposing of them in the garbage.

Once you have pruned the leaves, you should also take measures to improve the growing conditions of your pothos plant.

This may involve increasing the amount of humidity or light, as both of these factors can help prevent brown spots from occurring.

Repot your pothos plant:

If your pothos plant is showing signs of brown spots, it might be time to repot it. Repotting a pothos is a simple process that can be done in a few easy steps.

  • First, remove the plant from its current pot and gently rinse off all the soil.
  • Next, select a pot that is slightly larger than the original pot and fill it with fresh soil.
  • Place the plant in the new pot and cover it with soil, making sure to pack it down firmly.
  • Water the plant well and place it in a sunny spot; within a few weeks, you should start to see new growth.
