My coworker has had this plant since 2016. Itâs never been repotted as far as I know and used to be a lot bigger with a separate off shoot that died. Should I just repot it and hope for the best? Havenât looked at the roots yet, kinda worried they might be trashed (there is no drainage hole in this pot). Also, there is some white stuff on top of the soil, what is this? Thanks!
