i had about 50 seeds i started back a the first of this year , as they grew i moved each to a 3inch pot. had them on my porch where i watered them as they needed it . have leaves about 3 to 5 inches . about a month ago some looked as if they were starting to die. i keep all together and continued to water . we are expecting lows this weekend in the low 30s so i started moving them inside. the dead ones i removed from their soil just to look at them. the roots are whitesh and strong , the bulb is hard but the leaves are either gone or dead. the bulbs are about the size of a large kernel corn .. my question can these be put up and saved for replanting next year , your thoughts.
