Re: dis-mounting orchids
I'm hoping the orchid experts here will chime in, but I'll give my 2 cents.
P. grobyi can be moved to a new mount easily -- it seems to grow new roots readily. I've split mine, and I just yank a growth off and tie it down onto a mount.
Other genera can be much more finicky -- some of the non-terrarium orchids (Cattleya) I grow will not recover unless repotted only in a couple-week-long window each year.
I think I could turn and live with animals, they are so placid and self-contain'd.
