I'm having trouble with my dioscorea hemicrypta and dioscorea sylvatica. The caudexs on them have gone soft and spongey. I believe this is because I was watering them/got rained on when they were trying to go dorment.
Is there any chance for recovery?

Slim. Just keep dry and in Sun. Also some powered sulfur could help. It should not lower the ph to where it is unhealthy for the plant. Try not to handle. Some how it knows and don't like to be. Too small to cut off and would ruin the plant. It is what happens to me alot of the time.
