Here is an excellent resource for you. Suggest reading entire propagation instructions before proceeding though. I've used this method rather successfully. Good luck!
I had no idea this could be done. And even with the miniatures. I broke right now but I'm thinking about this August when about the last of the miniatures show up at lowe's.
I rooted some seven sisters this year. Took clippings dipped in rooting Harmone put in wet sand mix with Perlite to help hold moisture. After about two weeks I dug rough hole planted the cutting sand and all with potting soil I use liguid molasses and Fish Emulsion. Water good when you plant then depending on the weather (ours has been wet)water about twice a week after they get started. I water everyday at first if dry weather.
