I learned the hard way not to keep a prayer plant in an unglazed pot. It allows the roots to dry out too much and then its' not happy. Is it cold outside too?
Just wondering your location if you are in the north, south, etc, and if you could take a photo higher up so we could see the top of the soil that would be great. If that is the only stem, I don't know at this point what I would recommend for a fix.
