To encourage faster growth in Plumeria, provide optimal growing conditions. This includes sufficient sunlight, well-draining soil, and regular fertilization with a balanced fertilizer. Warm temperatures and proper care can stimulate growth. Additionally, protect the plant from pests and diseases that may slow down growth. Pruning the plant to remove leggy or weak growth can also redirect energy to new growth and encourage faster development. Monitor the plant’s progress and adjust care as needed to support its growth.
