Stem rot strikes again?

It looks as though stem rot has taken another Phalaenopsis from my collection this week. Recently, the plant has been dropping leaves, but these were yellow. Nothing out of the ordinary, I thought it was part of a natural process. This morning, when I was checking the orchid over, a green leaf came away in my hand. Not good.

Dealing with stem rot on a Phalaenopsis orchid

Occasionally Phalaenopsis orchids may fall foul of a type of rot. There are many different types that can affect orchids, but this time, we appear to be dealing with stem rot.
