For the most success, only propagate plants during the growing season (spring and summer). The 3 most common methods include:  Top Cutting - Count a few nodes or inches down from the bottom of the plant's top leaf line and cut the stem. Pot the cutting directly in soil or keep it in a vase of water until roots sprout. Stem Cutting - Follow the same method as with top cutting, but include several inches of stem in your cutting. Plant these in soil or keep them in water until roots sprout. Rhizome Cutting - Dracaenas that naturally spread via underground rhizomes, like snake plants, can be easily propagated by separating new plants that sprout from the rhizomes. Simply identify an individual rosette, break it off at the root, and keep it in water until new roots sprout.
