I have many cuttings now in all phases of rooting. I found the some do better than others. I am being luck with cuttings I put in a plastic tub lined with moist newspaper. I cut some styrfoam in strips and use them for shelving the cuttings, then I put another blanket of wet newspaper over the cuttings and close the box, lid is tight (these boxes come with greens for salad) I put the box leaning over the heating vents and rotate the box to get warm from both sides. I inspect them often and adjust as I think they need. The cuttings stay semi moist, as nothing is toughing the wet paper, except from the top, which dries up quickly.. the steamed up moist seem to ve working well. Once they grow little eyes, I move them to moss and have a heating coil on them - yeah.. a lot of handling... I also started others that were very long inside of tall water bottles, they appeared to be 2-3 y.o.with secondary growth, so I imagine I would get a head start by not cutting the secondary growth. I did not do the newspaper... I dipped them in hormone and planted them in the tall bottles. I lean the bottles sideways, so I can rotate them. I have new growth on these, same age as some in the plastic box. the box has roots and no leaf - so I am assuming some rooting is forming in the bottles. Love these experimenting.
