Thank you, I've been worrying about what to do with them. I didn't know if I should dig them out again, but I'll try leaving them in the pots, dry. I left an A.paeonifolius in a pot and it disappeared, leaving some dry flaky stuff.
By the way, I once lived in the Pioneer Valley; it is such a great place to live. The Lyman plant house has to be one of the nicest places I've ever seen.
