Do I need to dig up tubers in winter in So. Cal?
Hi, Dahlia-lovers. I am curious about growing them in Los Angeles. From what I've read, you're supposed to dig up the tubers in the fall and replant in the spring. Is that only necessary where the ground freezes? Since the ground does not freeze where I live, can I just leave them in the ground all year and will they come back in the spring? I realize that it would be good to dig up every few years, to divide, but otherwise....?
Thanks for your help!
