There's a daylily farm that I make a road trip to every year, that also peddles a variety of perennials. During my visit yesterday, I found that they had surprise lilies (Lycoris squamigera), which have been on my Want List forever. I know it's not the best time to dig them while their leaves are green, but this place is over a hundred miles away, they only sell on-site, and I can only get there once a season.
I got a really great deal on them, they dug them, and I brought them home. Today (I got home very late last night) I planted them in temporary containers, and, not knowing what to do, left the now drooping leaves on them.
How can I ensure that they will survive and grow? Should I have trimmed the leaves off? Let them dry out and plant them in autumn? What can I do to give them the best chance?
