we wrap orchid plants with coir and mount them on trees.
We are coir producing country and they make rugs with coir .They can be hanged on trees. I can try on it .As a new idea.
We just plant them on coconut husks and wood charcoal. Now I got your idea!
ACtually, all I did was cut a rectangular piece of coir, put some sphag on it, tied it, put the orchid on it, then another layer of sphag and then tie it again so the plant doesn't fall out. I can send you a pix tomorrow.
