Yes, Plumeria can be easily propagated from stem cuttings. Take 10-18 inch (25-45 cm) cuttings from healthy branches, and allow the cut ends to dry for a few days. Plant the cuttings in a well-draining potting mix, water lightly, and place in a warm, bright location. Roots should form within a few weeks to months. Plumeria cuttings root more readily in warm temperatures, so providing bottom heat or a heating pad can accelerate root development. Monitor the cuttings closely, and once rooted, care for them as you would mature Plumeria plants.
