The most common cause of yellowing leaves among Pothos plants is improper soil moisture, particularly overwatering. You should water your Pothos when the top 25% of the soil in the pot is dry. The soil should remain damp, but not soggy. In the winter, you can allow your plant to dry out a little more between waterings, but be sure to increase the humidity around your plant with regular misting or by using a humidifier.

If you allow the soil of your Pothos plant to dry out completely, you may notice its leaves becoming limp, droopy, and turning brown. To prevent this, ensure the soil remains moist but not wet. Additionally, Pothos plants thrive in a humid environment. You can increase humidity by misting the leaves regularly.

If your Pothos plant appears unhealthy, such as droopy or wilted, it requires some simple care. Start by removing any dead or damaged leaves. Check the soil moisture level, and add water if necessary. However, if you have been watering frequently and the soil is soggy, allow it to dry out completely. In case you are worried that the plant might not survive, take a few cuttings from its healthy growth to propagate into new plants.
