Moth Orchid: Difference between rot and natural leaf falling?

[JJC18]

Hi All,

Thank you for all of the help on my last thread on possible crown rot.

Is there any easy way to tell if leaves are falling off from stem rot or being dehydrated? Should the edge of the fallen off leaf be all yellow instead?

I noticed some black splotches in the area leaves have come off and wondered if that is normal or is that something else.

So far most of the leaves have fallen off from my trimming of what I thought to be rotting roots/repot but would like to know if there was any stem rotting.

It doesn’t seem like I can do that much anymore but hope that the crown is still good for regrowth. All advice is appreciated.

Thanks,

J
