What bark and moss for phals?

[viviana]

I will be up north for eight weeks and would like to secure my phals in a tree while I am gone. They grow well in a pot with the orchid bark mix. Can I use the Spanish moss as a cradle for the bark and orchid instead of the pot and carefully tie it to a shady crook of a tree? I could not find or order the wooden slatted baskets in time. Thank you.
