Single leaf yellowing?

[spinrah]

Thanks Roberta.
Sorry, I should clarify - I shouldn’t have said “breaking down.” What I meant was that the bark is starting to hold more moisture so I don’t want to leave it soaked in water as I had before. But the bark chips themselves are okay. Not the best quality, but they seem to be doing fine.

Here are some photos of the roots inside the pot. This is 4 days since watering. I would typically water it when it looks a little more dry than this (maybe tomorrow).

By the way, this was a grocery store purchase so the roots have looked pretty much like this since I got it - not too great but viable!
