I have had such terrible results with roottone, that I always recommend against it. My cuttings dipped in roottone almost always rot and die. However, my success with placing cutings in H2O is greater than 80%. As I stated in my postings in the other thread, if cuttings are placed in H20, it is important to remove all of the big/main leaves, because they require more energy to sustain than the cuttings can provide, AND it's imperative to change the water at least every other day. RichardK is right, that if placed into water, and left alone, the cuttings will rot. But if the water is changed frequently, water from the tap comes out aerated, and the stems are in an oxygen rich solution. I also recommended in my postings, that if you see evidence of rotting at the base of the cutting, it is important to cut or scrape it away.
