When it comes to houseplants, pothos is a popular choice for its hardiness and ease of care. However, even the most resilient plants can succumb to disease when the environment is not ideal. Pothos diseases include root rot, leaf spot, and blight. Each of these conditions can be caused by environmental stressors such as overwatering, underwatering, poor drainage, or low light conditions.
Root Rot
One of the most common problems for pothos is root rot caused by Phytophthora fungi. This disease is characterized by dark brown to black leaves that do not show signs of blackening on their veins or stems. It can also be accompanied by yellowing leaves all over the plant. To prevent root rot, it’s important to ensure that your pothos has well-draining soil and that you are not overwatering it. If you notice any signs of root rot in your plant, you should discard it immediately as well as any pots used to contain it as sclerotia may cling to them and infect other plants. You may also consider treating remaining plants with a fungicide drench containing pentachloronitrobenze (PCNB) or flutolanil.
Leaf Spot
Pothos can also suffer from leaf spot caused by various fungi including Alternaria and Cercospora species. This condition is characterized by reddish-brown spots on the leaves wich can spread quickly if left untreated. To prevent leaf spot, make sure your plant is getting enough light and that there are no fungal spores present in the soil or environment around your plant. If you see signs of leaf spot on your pothos, you should remove any affected leaves and treat with a fungicide containing copper sulfate or mancozeb.
Blight
Blight is another fungal infection that affects pothos plants and is caused by Pythium species fungi. It causes brown spots on the leaves which can spread quickly if left untreated. To prevent blight from occurring in your pothos plant make sure it has well drained soil and adequate airflow around it at all times as too much humidity can increase the risk of infection considerably. If you see signs of blight in your plant, remove affected leaves immediately and treat with a fungicide containing mancozeb or copper sulfate.
Overall, when caring for your pothos plants it’s important to keep an eye out for any signs of disease such as root rot, leaf spot or blight so they can be treated quickly before they spread further throughout the plant. Make sure they have access to plenty of light and water them regularly but don’t overwater them as this could lead to root rot which could kill off your entire plant!
Identifying Fungus on Pothos
Fungus on pothos typically looks like black, sooty mold and can be found growing on the surface of leaves. It may also be present in the form of powdery mildew, which is white or gray in color and appears as a coating on the leaves. In cases of Phytophthora root rot, fungus may appear as dark brown to black discoloration of the leaves and stems, with the veins remaining unaffected. The fungus may also cause the foliage to yellow and drop prematurely.

Diagnosing Problems with Pothos
If you’re not sure what’s wrong with your pothos, there are a few telltale signs that can help you figure it out. Check the leaves for any discoloration – yellowing, wilting, or brown spots. Inspect the soil around the root of the plant – if it’s damp and soggy, it could be a sign of overwatering. Check to see if the pot has adequate drainage by tipping it over and allowing any excess water to run out. Finally, take a look at how much sunlight your pothos is geting each day – too little light can cause yellowing leaves. If none of these issues seem to be present, it could be a nutrient deficiency – in this case, try diluting some liquid fertilizer into your watering routine for an extra boost.
Treating Fungal Infection in Pothos
To treat fungal infection in pothos, the first step is to discard any infected plants. Do not reuse pots, as sclerotia can cling to the sides and infect the next crop. To prevent further spread of infection, fungicide drenches containing pentachloronitrobenzene (PCNB) or flutolanil can be applied directly to the soil around the pothos. When uing fungicide, it is important to follow all label instructions precisely and take necessary safety precautions such as wearing gloves and a face mask. Additionally, it is essential to ensure that all areas of the plant are treated uniformly and no foliage remains dry. Finally, it is important to monitor the plants for signs of additional infection and apply treatments as necessary.
Reading the Signs: Understanding What Your Pothos Leaves Are Telling You
Your pothos leaves can tell you a lot about the care it’s receiving. Dark, soft spots on the leaves are usually an indication of overwatering, wile light, crisp spots can mean your plant is underwatered. Additionally, if the leaves are turning yellow or pale green and dropping off, this could be an indication of too much direct sunlight or a nutrient deficiency. Lastly, curled or browned edges could mean that the humidity levels in your home are low. By observing the condition of your pothos’ leaves, you can determine what tweaks to make to its care routine so it can thrive!
Signs of Thrips Infestation on Pothos
Thrips on pothos typically appear as small, cream-coloured or black insects with wings. They can be found on the undersides of leaves, where they feed by sucking out the sap. Signs of damage from thrips include discolored spots, silvering of leaves and deformed new growth. In severe cases, thrips can also cause entire leaves to become distorted or brown in color.

Identifying Fungal and Bacterial Infections in Plants
The most reliable way to tell if a plant is suffering from a fungal or bacterial disease is by closely examining the signs and symptoms of the plant. Fungal diseases are typically characterized by discoloration, spots, or lesions on leaves, stems, and/or fruits. These spots can range in color from yellow to brown and may also have an associted texture such as a powdery appearance. Additionally, fungal diseases often cause wilting or drooping of foliage and may also produce fruiting bodies such as mushrooms or conks. On the other hand, bacterial diseases usually manifest as spots with a distinct yellow halo around them and canker-like formations on stems and branches. Additionally, bacterial diseases can cause wilting or drooping of foliage as well as noxious odors due to certain species of bacteria producing toxins. Ultimately, a diagnosis should be made by a trained professional in order to accurately diagnose whether the plant is suffering from a fungal or bacterial disease.
Signs of Dehydration in a Pothos Plant
A dehydrated Pothos will typically look limp, droopy, and its leaves may start to brown. The soil will be completely dry and the plant may appear wilted or shriveled. The leaves may also feel brittle or papery to the touch. If you suspect your pothos is dehydrated, it’s important to give it a thorough soak-watering as soon as possible.
Effects of Too Much Sun on a Pothos Plant
A Pothos with too much sun will show signs of sunburn on its leaves. These sunburns appear as brown spots, usually on the variegated parts of the leaves. The spots are permanent and unfortunately cannot be healed, so if you want to get rid of them, you may have to trim off the affected leaf.
Signs of Overwatering in Pothos
To tell if your Pothos is overwatered, the first thing to check is the soil. If it feels soggy and waterlogged, this is a sure sign that it has been overwatered. Other signs include soft leaves that are wilting (even after watering), brown tips on new growth, mushy stems, brown or mushy spots on leaves, and smelly or moldy soil. If you notice any of these signs, it’s important to take action right away. Reduce the amount of water you give the plant and allow the soil to dry out more between waterings.

Appearance of Fungal Infection on Plants
A fungal infection on a plant can present with a variety of symptoms, depending on the type of fungus and the severity of the infection. Generally, common signs of a fungal infection include discoloration and wilting of leaves, leaf spots, blotches or rotted spots on fruits, powdery mildew on leaves, cankers or galls on stems and branches, abnormal growths or deformities on stems or roots, white cottony growths on the underside of leaves, and stunted plant growth. In severe cases, entire parts of the plant may die off as a result of the fungal infection.
Identifying Fungus on Plants
Fungus on a plant typically appears as rings or spots of brown on the leaves. These spots usually start out on the underside of the leaves, but they may eventually spread to both sides. The leaves can also yellow or fall off prematurely if they are brushed or rustled. In some cases, you may see white or gray fuzz on the leaf surface around the spots, which is called a fungal growth.
Distinguishing Fungal Leaf Spot from Bacterial Leaf Spot
To distinguish fungal leaf spot from bacterial leaf spot, it is important to look for visual cues. Fungal leaf spots commonly appear as small, circular spots with fringed edges and a dark center. Bacterial leaf spots are typically characterized by an irregular shape and often have yellowish margins or halo-like rings around them.
In addition to visual inspection, one can also use a moist chamber test. Place the leaves in a moist chamber and inspect them after two to three days for fungal structures such as little black dots in the lesions. Bacterial lesions tend to be ‘water-soaked’ or ‘glassy’ before they dry up when placed in a moist environment.
It is important to note that both types of leaf spot can be treated with fungicides or antibiotics, depending on whch type of disease is present.
The Benefits of Wiping Pothos Leaves
Yes, you should wipe the leaves of your pothos plant with a damp cloth. Dust accumulates quickly on their broad leaves and can interfere with photosynthesis. It also makes the plant look unsightly. Wiping down the leaves regularly will help keep your pothos looking its best and ensure that it is getting all the light it needs to stay healthy.

Removing Damaged Pothos Leaves: Is it Necessary?
Yes, it is important to remove damaged pothos leaves. Doing this will help the plant focus its energy on healthy new growth. To remove the leaves, simply use clean scissors or pruning shears to make a clean cut at the base of the leaf stem. If the leaf stem is thick or woody, you may need to use a knife to help you make a smooth cut. It is important to remember that you should never tear off damaged leaves as this can damage the plant and leave it vulnerable to infections or other diseases.
Do Pothos Prefer Climbing or Hanging?
Pothos are a naturally vining plant, so they prefer to climb upwards. They enjoy reaching for the sunlight and growing vertically. When grown indoors, pothos plants can be trained to climb up trellises, walls, shelves, rafters, or other installations. For hanging plants, some cultivars of pothos feature long trailing vines that look great in a hanging basket or macrame wall hanger.
Conclusion
In conclusion, pothos plants can become infected with a number of diseases, such as Phytophthora root rot and overwatering or under-watering. Signs of these diseases include yellowing leaves and brown spots on the leaves. To treat and prevent these diseases, it is important to properly water and provide the rght amount of sunlight for your pothos plant. If you think your pothos may be infected with a disease, consider using a fungicide drench containing PCNB or flutolanil. Finally, discard any infected plants and do not reuse pots, as sclerotia often cling to the sides of pots which can infect other plants.
