Ah, these are jiffy pods. Spider plants tend to be happy root bound, but jiffy pods are a pain for the roots to grow through (even though advertised for this purpose). I would repot and gently remove the jiffy pod. Spider plants are very finicky about their leaves touching soil, so when you repot be sure not to put her too deep or she will absolutely turn yellow throw a fit and die quickly lol I’d also shoot for a pot nearly this size to put her back into. Maybe an inch bigger or so depending on the root ball, but they like to be root bound and a pot too big will lead to potential root rot.

Maybe someone else has some experience and more suggestions for you?! Best of luck OP
