Mounting on a tree & dividing plants

[BURR]

I want to move a lot of my Orchids to trees.

I am running out of fence to hang baskets on because everyone keeps giving me new Orchids.

So two questions:

I understand I can just cut down beside the main stem and then mount or plant this bunch of roots. I’m talking about plants with roots growing out the top and sides. I need to do something.

To hang them on a tree should I put half a coconut against the roots as a cover?
