I've tried repotting it, trimming off the dead roots,
cutting off the "bad" parts of leaves, and spraying it with anti-fungals
(physan 20 and neem) but it hasn't perked up yet. It hasn't grown at
all in a while and it just keeps getting worse. The places I trimmed the
leaves have turned brown and the whole plant is looking unhappy with
dried out leaves. Any suggestions or is it just a matter of time before
the plant dies?

Thanks for any advice!!
