Too late to dig up in Zone 5?
I thought I posted this already but I guess not. My dahlias were frosted in Early November and cut down 2 weeks ago. With one thing and another (and another and anotherÂ) I did not get them dug yet. I am in Zone 5 Chicago. Temps have dipped below freezing many times so far, and then back up.
Is it too late? Will they be dead?
