What are the names of the two dahlias in pic??? How are your dahlias doing presently? When will you start to dig them and divide the tubers?

"Ruthann" is in the foreground and that is "Summer Night" behind her. Summer Night bloomed like crazy by the end of Summer. Its dark color makes the other dahlia colors in an arrangement pop right out. I started cutting stalks last week and began digging yesterday. In my experience, I've found that by cutting the stalks and then waiting several days before digging, it is easier to see the eyes. Sunday night was our first hard frost.
