The ground was frozen here this morning. They hibernate in our sunroom till about April and start to sprout. I water them once every 2 weeks during the winter. They are in leaky pots with a pan below them so they are never sopping wet. In the summer when they are growing fast they get watered everyday, but the extra water leaks out the bottom outside.

I'm curious what the larger plant is beside the healthy stevia. Looks like a tree sapling? Could that be pulling too much water/nutrients away from the stevia?
I'd consider transplanting the healthy stevia into its own pot. Use fresh soil, in case there was a soil borne disease that got to the wilted ones.
