Can you overwinter dahlias? I live in Southeast Alaska and have 24 plants in my flower box coming up to my main entry to the house. I would like to replant them next year if I can get them through the winter months. Thank you.
The key is to let them dry before you store either on paper or a wire dust with fungicide for extra safety and place them in a dry box or paper sack with dry sphagnum moss you get at the garden center. Keep them dry and plant back out in the spring.
