Hi ! I was wondering if anyone could help me out.Here`s the question: do I need to use bark medium from a store or I could take some bark from some dead trees I have in my garden? I heard that some people use that bark from their own garden, but they put it firs in the owen for 10 minutes. Since I can`t find any medium for orchids here in Belgrade, I am hopping that this could be the way to repot my Phal when the time comes. Just one more question: does it need to be bark from a decidius or from a conifer tree? Thanks!!
