I just take the cutting as described, clean knife/razor, cut at 45% angle, not too many leaves or too big, dip it into bit of rooting compound , make a hole in small cup of good dirt with pencil, stick cutting in and tap dirt around it...then take old big plastic coke bottle, cut top off and make a "dome" leaving the cap off....creates a nice humid atmosphere.....keep it watered and in medium sunlight and in week or so get roots on most all of them...then transplant to bigger container....maybe just lucky but works well for me and pretty simple to do.
