So I planted this terrarium with Selaginella apoda and some moss, and while the moss seems to be doing ok, a huge patch of the selaginella has died, and I’m not sure why.
It was on a north-facing window while I was away for 3 weeks, I came home and half of it was dead. In the last week or so, I tried moving it under a grow light, and it’s just getting worse.
Is it doomed, or can it be saved?
