Your pothos will tell you something’s wrong through some major signs. There will be more subtle leaf changes through to some very obvious signs that’s it’s struggling.

And once you know what to look for you can spot the warning signs and take action before your pothos gets any permanent damage.

So go through the following causes of root rot and use them to help you figure out if it’s the problem with your pothos as well as ways to bring your plant back to health.

Understanding Root Rot in Pothos

Root rot happens when the roots of your pothos don’t get enough oxygen. This is usually down to there being too much moisture.

That excess moisture will encourage fungus to grow and this leads to decaying roots and an unhappy, stressed plant.

Signs of Root Rot in Pothos

Finding your plant has root rot early and treating it quickly can be then difference between a plant you can save and one you can’t. So look out for these signs:

1. Yellowing Leaves

If your pothos leaves are turning yellow, especially the ones lower down the plant, it might be a sign of root rot.

When the roots becomes damaged they can’t take up the nutrients from the soil the plant needs. When the leaves don’t get those nutrients they can respond by turning yellow.

2. Wilting and Drooping

Even if your pothos is getting enough water your pothos can still look droopy and be wilting if the roots are rotting. This happens because the roots can’t absorb water properly.

3. Brown or Black Leaf Spots

Dark spots or patches on the leaves are a sign of a fungus infection that is associated with root rot. The spots can merge with each other and make larger blotches.

4. Mushy or Discolored Roots

Healthy pothos roots will feel firm and look white or tan in color. If the roots are rotting they will turn black or brown and be mushy. They might also smell really bad.

5. Mold or Fungus on Soil Surface

If the surface of your pothos soil has a white or yellow growth on it that is a sign of too much moisture and can lead to root rot.

6. Stunted Growth

If you’ve seen your pothos not growing as well as it was then that could be down to root rot slowing it down because it’s not absorbing the nutrients it needs.

7. Presence of Pests

When a pothos becomes weaker from root rot it makes it more likely to get pests like mealybugs, aphids and spider mites, which are attracted to stressed plants.

Causes of Root Rot in Pothos

Understanding what leads to root rot can help you stop it from happening.

1. Overwatering

Pothos like the soil to dry out between each water. Too much water will keep the soil damp and moist all the time and this will stop the roots from getting the oxygen they need and leading to rot.

2. Poor Drainage

If you’re using a pot that doesn’t have any drainage holes then the water can build up and cause the roots to rot. Heavy soil will also trap the water and cause the same problem.

3. Oversized Pots

But a pot that’s too big will also cause issues. A larger pot means more soil and this holds on to water for longer and can mean you end up overwatering your plant.

4. Low Temperatures

Pothos plants like the temperature to stay between 65 to 80°F (18-27°C). If it’s too cold then that can slow down how it absorbs the water, which will make the soil stay wet for longer and increase the risk of root rot.

5. Fungal Infections

Pathogens like Phytophthora, Pythium and Rhizoctonia grow in conditions where soil is moist and can infect the roots and cause them to rot.

How to Fix Root Rot in Pothos

If you think your pothos has root rot take these steps to save it:

1. Remove the Plant from Its Pot

Take your pothos out of its pot to get a good look at the roots. Be careful not to damage the healthy roots as you do this.

2. Rinse the Roots

Wash the roots under lukewarm water to get rid of the soil. You’ll then be able to see how bad the rot is.

3. Trim Affected Roots

Use scissors or shears and cut away the mushy or black roots. The healthy ones will be white and firm.

4. Disinfect the Remaining Roots

Soak the healthy roots in a solution of one part hydrogen peroxide to four parts water. This helps get rid of any fungal spores that are leftover.

5. Repot the Plant

Fill a clean pot with fresh potting mix. Make sure the pot has lots of drainage holes. And then replant your pothos making sure the roots are spread out and fully covered with soil.

6. Adjust Watering Practices

Once you’ve repotted it water your pothos a little. Let the top inch or so of the soil dry out between each watering so the rot doesn’t happen again.

Preventing Root Rot in Pothos

Stopping rot from happening is always better than trying to cure it. So follow these tips to stop it before it begins:

1. Proper Watering

  • Water your pothos only when the top inch of soil feels dry.
  • Change how often you’re watering based on the seasons – plants will need less water in the cooler months.

2. Use Well Draining Soil

  • Use a potting mix that is designed for indoor plants. Or you can make your own by mixing equal parts of potting soil, perlite and coconut coir or peat moss.
  • Don’t use heavy soils that hold on to too much moisture.

3. Select the Right Pot

  • Always use a pot with lots of drainage holes so the excess water can escape.
  • Don’t choose a pot that is too large as they hold on to more water than the smaller ones.

4. Maintain a Consistent Temperature

  • Keep your pothos in an environment between 65°F and 80°F (18°C to 27°C).
  • Don’t put your plant near any drafty windows or air conditioners.

5. Monitor Humidity Levels

Pothos do best in moderate humidity. If your home is very dry you can mist your plant occasionally or use a humidifier.

6. Inspect the Plant Regularly

  • Check your pothos for early signs of stress or pests. These can make you plant more likely to get rotting roots.
  • Keep a close eye on the level of moisture in the soil so you don’t overwater.

7. Use Fungicide When Necessary

  • If you suspect fungus then use a diluted fungicide on the soil.
  • Always follow the instructions on the label so you don’t harm your pothos.
