How can I successfully propagate Dracaena fragrans plants?

To successfully propagate Dracaena fragrans plants, you can use stem cuttings or air layering methods. For stem cuttings, take a cutting from a healthy plant and place it in water or soil to root. For air layering, make a small incision in a healthy stem, wrap it in moist moss, and wait for roots to form before cutting it off and planting it. Keep the new plant in a warm, humid environment with indirect sunlight to help it grow.
