Dear Bulb Enthusiasts, I thank all who provided advice on overwintering dahlia tubers. I carefully dug the plant out [this was easy as I had planted it in a 6 in. pot with plenty holes in the bottom and buried the pot to the rim]; cut the stem at 6 in.; let in dry for several days in my shed; and now have it inside to further dry before storing it for the winter as recommended. Only, the elongated roots radiating from the crown are a bit soft or spongy, the same for the roundish bulges below it [I don't know how the latter are called]. Is this normal, or am I doing anything incorrectly? As further info, we had a good frost [-2 C ; 29 F] - not a freeze - two days before I uplifted the plant, but the ground did not freeze. I'd be grateful for any advice. Sincerely, J. Denys Bourque Saint-Jacques, NB CANADA US Zone 4 ; Canadian Zone 3a
