Hey guys, I have some S. Flavas that all of a sudden just started withering away... the tubers do not look dormant they look dead. From my understanding the rhizome is supposed to be whitish inside... they are brown and dieing. Any clue what might be triggering this?? I figured it might be all the rain we've been haveing the last few months flooding the bog and keeping the rhizomes compleatly submerged. any tips??
