I tend to sound like a broken record on the subject of rooting cuttings. I prefer the Forsyth Pot method. (Lots of information all over the internet.) I use Vermiculite as the medium and, after the cuttings have formed roots, I do not remove any Vermiculite that adheres to the roots. Just plant the rooted cuttings in your preferred type of planting medium and...no problems yet.
I first learned about this method from zuzu'spetals when I was a member of PlantSwap.net:

By the way, the originator of this method...his surname was Forsyth...not Forsythe. And of course, he was Scottish.
