Remove the leaves from the bottom half of the cutting, dip it in rooting hormone, and insert it in a moistened potting mix. Place the pot in a warm, bright area and cover it with a plastic bag or a glass jar to maintain humidity. The cuttings should root in about four to six weeks. Once rooted, remove the covering and move the plants to a brighter location.
Layering
Another method of propagating Mussaenda arcuata Lam. ex Poir. var. pubescens Wernham is layering. This method involves bending a low-hanging branch to the ground and burying a portion of it in the soil. Once the branch is secured in the soil, it should be kept moist.
