Fill a pot with a potting soil similar to the original potting soil. Aeonium does well in a commercial potting mix for cacti and succulents, or a pot filled with one-third coarse sand, one part regular potting soil and one part pumice.
Break or cut a rosette from a healty aeonium plant. Leave at least 1 inch of stem attached to the rosette.
Set the rosette aside in a shady spot until the break forms a callus -- about two or three days.
Plant the rosette in the prepared container, with the woody stem in the soil and the rosette above. The stem will grow new roots.
Place the pot in partial shade or filtered sunlight and normal room temperature. Avoid hot, direct sunlight, which will kill the plant.
Water the potting soil lightly after planting. Thereafter, water aeonium on the same schedule as the parent plant. Allow the soil to dry slightly between waterings, and never allow the soil to become soggy.
