Sandi has all valid points!
Jungleboy--You can do that, keep the pothos in water. But long term what is best for the plant is to be in soil. As yours gets gangly you could take cuttings, put them in water with a little hydrogen peroxide added. Let them form roots, keep them a little while that way and then pot. Give another haircut to pothos and do the same. Eventually you will have more than you know what to do with --give them to friends. That way you get the "look" but the plant gets to be planted! Sometimes surviving is not flourishing. Many blessings for a totally awesome August!
