yes, you can air-layer it, but you would have to do it on older woody growth.

very young green stems do not work well for air layers or cuttings.

cuttings usually root pretty easy. keep warm and humid.

one way, is simply by taking a vine and training it along the ground, and putting soil on top a section of it... add a little much or leaves on top so it doesnt dry out.

roots should form soon.
