With the yucca plant, your website says strip all but a few leaves and then let it dry out. So, I don't want to place the cut end (or the broken end) in water to encourage root growth? I know with many species that's the plan (like the potato plant). I ask because this seems backwards to me. Don't the roots want to grow before it goes in soil? Is there any particular type of soil it needs? What about root growth hormone, like for the jade plant?
