I had some spare cuttings and did not want to devote lot of time to them. A zip lock bag 1/2 full of my ordinary rooting mixture(perlite, vermiculite and coir), slightly moist. Bury the cuttings in the mix, closed the bag and put in a bottom drawer. A few weeks later one of them has roots. The other has produced stems and leaves, but no roots. A little while longer. It's nothing new, but this method appeals to the loafer in me. I have to re size the photos before posting.
