@lauriebasler , I did not do anything special. I just pushed the pieces down in regular potting soil and I kept the soil moist.
When I amend my soil I use aquarium gravel. I have so much of it because I have so much of it from my aquariums. When the gravel gets old and ugly I put it in a bucket and save it for the garden. Because of our winter moisture of rain, snow, then ice in a matter of days I have to have almost total gravel for the sedum. So I use 80% gravel and 20% soil on top of large rocks.
