I agree. Don't put it in a larger pot or you could have root rot problems. If you feel that the potting media is breaking down, then re pot. Phals seem to respond well to re potting.
I bow to my fellow boarders superior Knowledge - never heard of Trichocentrum, but then I don't grow many Oncidium types. In that case try this for general care AOS | Oncidium
Thank you for the feedback (our dog Sky appreciates your kind compliment, Hedge). I did buy a mule ear bag baby from Lowes when I first fell for orchids almost 2 years ago. I thought that I had killed it in my first clumsy attempts. It is a nice surprise that it made it through.
