This is my first post. Unfortunately I can't post a picture yet, but I'll give as much information as possible.
In the past six months my phalaenopsis has grown three beautiful aerial roots. I bought this plant in the beginning of 2012, so I thought it was time to repot it. Shortly after (maybe a week) I noticed one of the roots starting to look funny. As I'm writing this and comparing one root to another, it seems like the sick one is retaining water. I watered a couple days ago, and the other two are all silvery. Any ideas what might be causing this?
Root turnover in plants. Roots are fairly short lived, and go through a life cycle. As long as not all are turning brown and dying... the nice silver ones are the young healthy roots.
