Rot is also the big killer after their mature plants, bloomed and you want to divide them. I know this from dividing a couple, about 1/3 will die no matter what you dip them in or power them with. I did everything I have been told to do, soak them in Banrot and a couple other rot chemicals, powered them after drying, and let them set 24 hours before planting. This has been my experience with conversions and may be one reason why their so expensive.
