Since you're new to cloning, as I am, I would recommend trying several different methods. You might find they all work very well and boost your confidence levels. Right now I'm experimenting with some different methods..
1) Branches with several nodes in wet ProMix, ends had been dipped in rooting powder, kept with a clear bag over the top for 3-4 days for moisture control. Just removed the bags today..
2) Branches with several nodes, bottom node trimmed and placed in cups of water
3) Some of the trimmings from (2) are also placed in water
4) A couple of leaves (only the leaf and about 2" of its stem) placed in some kind of flowering foam, they come in green bricks you can cut easily with a knife, cut to fit jars that I fill with water. I noticed that these dehydrate very fast because of the surface area of the foam, so I cut up some pieces of white/black plastic and placed them on top of the foam around the stem white side up.
Only the first one (1) look like sorry plants, but the tops are still pointing up.. I'm on day 5. The rest are only on day 2, but are still firm and rigid and look healthy.
