You make a cut 2-4 inches below the leaf area & allow to air dry. Apply 0.1% IBA (rooting hormone) Stick in well drained soil Keep soil damp & mist foilage will take 20-60 days to root,
The remainding stem in the pot should break a bud or two & continue its growth. Could also cut the remainding stem in4 inch pieces. lay on side & keep soil damp.

These are commonly sold in stem sections containing a node. When laid horizontal in moist soil, growth starts from the node and soon makes a plant. Al

Thanks.
