Plant your pothos in a pot with drainage holes, and use a well-draining potting mix. If your container doesn’t have drainage holes, the excess water will build up at the bottom of the pot.
Always let the soil in the pot dry to a depth of 2 inches before watering your plant. If you’re using containers 8 inches wide (approximately one US gallon) or bigger, allow the soil to dry to a depth of at least ⅓ of the pot’s height.
Your watering schedule will change throughout the year depending on several factors. And if you use a strict routine, you’re more likely to overwater or underwater your plant.
