My snake plant (mother- in- law tongue) is approx. 12 inches tall & looks healthy except one of the stalks has a 4 " crack in it. What caused it and will it affect the future health of the plant? I would like to start new plants from cuttings from my grape ivy, spider plant, pothos & split leaf philodendron. Will I have the same results by dipping the cutting in root powder & then plant or putting the cuttings in water until roots are formed and then plant in soil?
