Overwatering is the number one cause for pothos leaves turning yellow. It’s an easy mistake to make because pothos is a tropical plant, so you would think it needs a lot of water to survive.
Pothos can be very forgiving if you forget to water it for a couple of days. But if the plant goes without water for too long, especially in a bright, dry room, the leaves will gradually turn yellow.
Root rot is the most common disease for pothos plants. It is caused by several species in the Phytophthora and Rhizoctonia genus.
Like all potted plants, pothos needs regular feeding throughout the growing season. If the soil is poor in nutrients, its growth will become stunted, and the plant will eventually die.
