How can I successfully propagate a rubber plant in either water or soil?

To successfully propagate a rubber plant in water, cut a healthy stem with at least two leaves and place it in a jar of water. Change the water every few days and wait for roots to grow before transferring it to soil. To propagate in soil, take a cutting with at least two leaves and plant it in a pot with well-draining soil. Keep the soil moist and place the pot in a warm, bright location.
