The process of reproduction occurs with green cuttings, air layering, but
the simplest is propagation by offspring i.e extraction of young shoots with
roots.
Cuttings are practiced at the end of summer ;place them in a damp
sandy trench in the open air. The stems of the plant are hollow ,so cut
directly under the leaf node where there should be no voids . Water the
the plants as needed. Grow in any well drained or most drained soil in sun or
shade.
