Water propagation. Finally. Roots! Make sure the stem is completely dry and healed before putting into water, 3-5 days. If you put it in water when the cut is still fresh, it will absorb too much water and rot. Place succulent in water. Distilled water is best but tap is fine. I use tap myself. ☺️ Water should cover about 1/4" stem only, never the leaves. Keep it somewhere in bright shade. Not direct sun, but not darkened shade. In my experience, I usually see tiny roots form in 4-5 days.
