My basjoo looked like withered dead cornstalks as well. In fear of loosing two 4' basjoos I decided to take them out of storage and pull off the dead leaf petioles on the pseudostem. I thought for sure I would have lost a 1' of pseudostem on each plant, but to my amazement no height was lost! The two basjoos look excellent and I am looking forward to seeing new growth in the coming weeks.
I still have one 5' basjoo in my storage room that doesn't look as brown as the other ones did. I will leave this one until spring since the leaves will hit my ceiling if I plant it inside.
My storage room seems to hover around 58 degrees with no growth from the plants. Hope this will bring you some reassurence.
