Trace, I have typically in the past either laid them on the top of the medium (different for everyone, but fast draining) or root pretty shallow. I keep my cuttings in baggies(freezer size) and mist them, if you see any condensation, open the bag for a while, this will cause them to rot. Mine have taken a few weeks, be patient, as long as they look healthy, give them a chance.

Hope this helps
