Colocasia

From: MJ Hatfield <oneota at ames.net> on 1997.10.27 at 20:21:59(1515) I dug my Colocasias (bought simply as Elephant Ears) only to find that two out of four had tuber/rhizome(?)rot. There was nothing on above ground growth to indicate any trouble. The rot was much like what ate one of my Amorphophalluses last year. What might this be? And is the only future preventative to plant them in sterile soil in pots rather than in the ground? I am particularly curious because I have had Sclerotium rolsii (Southern blight) show up in my yard and it has hundreds of host species. (ISU Plant Pathology says that it is rare this far north) A.rolfsii seems to attack a plant right at the crown at soil level so I doubt that this tuber rot is a result ot it. Please, tell me anything. Thanks. MJ Hatfield
