Daylilies are very forgiving. You can dig them spring, summer and early fall. If you are going to ship some, make sure you wash all the dirt off the roots first, let them dry a bit, cut the foliage back to three or four inches, wrap in newspaper, and ship priority mail on a Monday or Tuesday to make sure they don't sit on a postal truck over the weekend.
Daylilies prefer to be shipped, bare root. Hope this answers your question.
