Cut a 3-inch piece of top growth from the plant for each cutting.
Remove the leaves from the lower half of the cutting.
Dip the cut end of the stem in rooting hormone.
Fill a small pot with equal parts coarse sand and peat moss.
Make an indentation in the center of the sand-peat moss mixture, using a pencil. Push straight down, about 1 1/2 inch deep.
Insert the cut end of the stem into the indentation and pat the soil mixture to firm around the cutting.
Water the container to moisten the soil without making it muddy. Cover the pot with a clear plastic bag to create a greenhouse effect. Position the plant in indirect sunlight and keep the soil moist.
Remove the plastic bag after the cutting develops roots. Test the cutting every couple weeks by giving it a gently tug. Once roots develop, it will hold onto the soil.
