I have no training is propagation I just like to try everything when I get it. I take the rose that has bloomed off to the first set of five leaves. Dead head the rose and I leave two sets of leaves. I do that so I can tell in a couple of days if they are doing. If they are they stay healthy if not they wilt and I promptly pull them out. I just keep close to a source of water and keep them damp. . If they take I smile it they do not it is oh well. Late fall I took a long stem from the pink shrub rose and just stuck it in a pot. I mean this thing was at least two and half feet long. I kept it damp and under a camelia bush and away it went. I planted it earlier this week and it is blooming. I am still trying to get to all the new dirt and mulching I need to do done. I took three smaller stem cuttings at the same time and one died and two are puting out leaves. I like to do things in threes. I just stick anything and keep it damp. It is surprising how many take. I think the secret is just good potting soil and keep it damp. Here is a pic
