Care for the plant as usual during the period after blooming to keep it healthy so it can produce pups. Allow the pups to grow to at least one-third, preferably half, of the height of the mother plant. Pups may put out their own roots, but it's not important that they do, as they root easily.
Hold the pup securely, and use a serrated knife or small saw to cut the pup away as close to the mother plant as possible. Lay the pup aside to cure the stem for 24 hours.
Mix potting soil and perlite in a 50-50 ratio. Fill a clay or plastic pot with the mix to within 1 inch of the top.
Dip only the very bottom of the stem of the pup in rooting hormone, and stick into the pot. Anchor for stability if necessary. Water well and add water to the vase-like center of the plant.
