You can easily grow pearls and jade pothos in water. You only need a jar, tap water, and liquid fertilizer. Choose a healthy stem with three or four nodes and cut with a sterile blade. Then clear away the leaves nearest the cut part of the stem. Your pothos mustn't have any leaves sitting underwater because they will rot. Once you have all the cuttings in the jar, add a few drops of liquid fertilizer. You should plan on changing out the water every two or three weeks. Or at least until the water becomes brackish.
