air layering

Air layering is a horticultural technique used for plant propagation. It involves inducing a plant to grow roots on a stem while it is still attached to the parent plant.1

This method is particularly useful for plants that are difficult to propagate through other means, such as grafting or budding. In air layering, a branch or shoot is wounded or girdled, and then enclosed in a moist medium like sphagnum moss or soil. Once roots develop on the enclosed section, the branch is severed from the parent plant and transplanted to grow as an independent plant. This technique was practiced by ancient civilizations like the Egyptians and Greeks.21
