A fair point Kevin and nature does influence the way I mount. As one of the most obvious examples, when I mounted some Sarcochilus australis earlier this year (reputedly difficult to grow) I attached them to a live prickly current bush (a natural host) and grew them in a breezy position in the hope that this more natural setup would maximise my chance of success. I guess instead of truly growing this species, it's probably more accurate to say it grows in my backyard
