As a result of a previous question, I've decided to repot my Phalaenopsis orchid in bark once the blooms fall off. I understand that tree bark makes a better medium than the moss it's currently growing on. In addition, I have no way of knowing how long it's been since the plant has been repotted.
Do I need to buy a specialty bark medium designed for orchids or can I use bark from the cedar trees in front of my house?
(I'm not opposed to spending a bit of cash on this plant, but I do like the idea of reusing materials that are at hand if possible. Seems like a waste to get a bag of tree bark when I have more than I can use already.)
