How often should I water this houseplant?
Your plant is a pothos plant. You can easily kill these plants by over watering, so when in doubt do not water. Water a pothos plant well, until the water comes out the drip holes in the bottom of the pot, and then allow the top 50% of the soil to dry out before watering again. Over-watering is almost the only way to kill a pothos. Bright yellow leaves indicate that a pothos has gotten too dry before you watered it. This can cause you to lose a few laves but the plant will be fine. New growth and parts of older leaves turn black when a pothos plant is over-watered. This indicates that the roots have stayed too wet and may be damaged. I recommend waiting until the leaves get a little soft and droop just a tiny bit before watering a pothos. Never allow a pothos to sit in water for more than 10 minutes.
