I was given a vanda orchid about a month ago. It does not have blooms, and appears to be potted in a charcoal like substance. A little while ago, one of my cats knocked the orchid pot over, spilling the potting medium. I then noticed that all the vanda's roots seem shriveled. It has no healthy roots at all. What can I do? Shall I re-pot it into the same charcoal substance, or should I use corks? I saw a suggestion about corks on one of the other forums. I am very concerned about theses dry and shriveled roots. HELP!
