Thanks, Eric!
I did find... 2 to 4" deep, top with 1 to 2" of mulch. Plant with the top of the crown about 2 to 4" below the soil so that a good portion of the old stems are buried. (Hallson Gardens)
I am going to float them out into a bucket with water and a few drops of superthrive for 30-60 minutes so they get good and hydrated. Then I will plant them at least 3" down but probably closer to the full 4" since I my zone is their northern limit. (This is how I treat peonies and hopefully this works fairly well here.)
