I've been over-wintering Blue Javas for 3 years now. Main thing to remember is to keep them DRY. Also, I Never over-winter below 50 degrees F. That may be why they're yellowing & going limp. Anyway, that's what mine do when they get too cold. If ya left the leaves on, they will slowly die over the winter. Main thing is to check the corms & make sure they dont have any soft spots. I leave mine in pots of dry dirt so I'm not familiar with the bare-root method. But from what I've read, here at the org, dried roots won't keep the corm from coming back to life in the spring.
If anyone else does bare-root over-wintering, please join in on this thread
