Take each stem and remove the bloom. Take of the bottom sets of leaves off and make a fresh cut on a diagonal. Dip the stem in a rooting hormone of some kind. Place the cutting in a clear plastic cup, with a hole in the bottom, of potting soil and put it outside in morning sun. Keep it moist but not soggy wet. And wait. It can take anywhere from 4 to 8 weeks to root. You will be able to see roots through the clear cup when they grow.
