Propagating Trumpet Vine by Layering: A Reliable Method

Layering: The Sure Way to Start Trumpet Vine

If seeds fail (some cultivars are sterile), use layering. In spring, select a flexible stem, scrape a 2-inch section of outer bark, dust with rooting hormone, and bury that section 3 inches deep. Anchor with a rock. In 8 weeks, roots form. By summer's end, sever the new plant and transplant to full sun.

This method works for many vines and shrubs. It's simple and highly successful.
