How often you need to water Emerald green pothos depends on several factors: room temperature, humidity, light availability, and pot size. There’s not a good one-size-fits-all watering guide for pothos.
If the plant does not receive enough light, its growth will become stunted. At the same time, direct sunlight can burn the foliage. Pothos is a tropical plant, so try to recreate the dappled light it would receive in its natural jungle habit.
Emerald pothos will grow well in most well-draining soil mixtures. You can purchase soil specifically for members of the arum family. Or you can make your own by combining basic potting mix with perlite, vermiculite, or sand.
