I just dig and wash, then air dry. If you ship in the summer or anytime in the warmer weather then it is importand to make sure they are dry before wrapping and packing. I usually wrap each bunch of daylilies in newspaper and put in newspaper lined box. If I have any lose spaces I stuff with crushed newspapers.
I don't soak them in bleach or anything like that but I don't have rust, thank goodness.
