I don't know if it is the rest period or root rot surfacing. As I have
one that had root rot and the stems went brown and collapsed like they
seem to do with the ones I still have (which are still flowering now or
reflowering t be more accurate).

So I'm puzzled... would this be root rot or rest period? How to tell
the difference between the 2? I would cut the bulb but I don't know
which colour is supposed to have a healthy one. Yellow? White? Brown?


I never cut into my Glox bulbs so don't know what color they should be.
Watering should be slowed and the plant allowed to dry off and die down when
you see the flower production come to a stop and the leaves look yellowish
and worn. I called it their rest period and let them be for a few months,
then repotted them and put them in a sunny west window to start another
cycle. Here's a website covering this beautiful plant. I don't grow them
anymore due to space limitations indoors.
