Hey Brion, I would probebly use some fiber twine for tying up plants in the garden. I got some at lowes or wally world for a buck. And still have tons left. I used it to old my anubias in place on the driftwood untill the roots could really take hold. After a month or so the twine roted in two and by that time the roots had taken hold. My concern with epoxy would be that it could damage the plant. But I have no experience trying it that way.
