Plants can be successfully propagated in either soil or water first and then soil. In either case, the potting soil has to be sufficiently porous, the pot small, and the soil must be maintained with the right balance between water and oxygen around the roots.
When making the transition, it is the new roots (not the leaves) that must be barely covered with a damp, soilless, peat-based potting mix with added perlite to increase porosity. Do not use regular garden soil. Use a pot that is just barely large enough to accommodate the roots and enough potting mix to barely cover them. Try to keep that potting mix damp but not wet so that the water-grown roots can make the transition to soil.
