What Works For Me
As you can see I use small pots to root my cuttings, 1.5" for Miniatures & Dwarfs, 2" for the rest. The pots once filled with cutting mix, are then stood in a saucer of water until wet. I then make a hole with a dibber, into which the cutting is placed. Firm the compost around the cutting with fingers, and of course ensure it has a label. When the cutting dries out it is stood in a saucer of water until sufficiently wet. I do not personally believe in spraying cuttings whilst rooting.
This is what I do to some of the problem Angels. I take a 2.5" pot, put some cutting mix in the bottom, then place a 1.5" pot in the middle and fill in around the sides with the mixture firming as I go. Any compost that gets in the middle pot is emptied out. Place the cuttings in between the 2 pots, firming in around each one. As you can see in the photo this works well as all are rooted. I removed a cutting so the inner pot could be seen.
