I may have mentioned I have begun growing ssome plants mounted now that
I have a greenhouse. Laelia anceps, for one, never seemed happy in a pot
no matter how loosely potted nor in any sort of mix, yet died when
mounted due to my dry conditions. Now they are mounted on cork and
misted 2-3 times a day. Similarly, I have now mounted two schomburgkias
(Laelias in all bu name to me), Onc.onustum, Laelia rubescens (also
never happy in a pot), Epi.parkinsonianum, and two Holcoglossums.

About 10-12 years ago I was trying to collect brassavola species (not
realizing it was virtually impossible to get most of them in the US) and
have stuggled with them ever since. They weren't happy in coarse bark,
fine bark, recycled rubber tire chips, aliflor, or tree fern. They only
wanted to thrive after they had crawled out of the pot and begun to glue
their roots to the outside of the their pots.

I was having a hard time deciding on the right mount for them - treefern
slabs would be too dense and too moist. Cork never seems to hold any
water at all, and sphagnum on it would not allow the open air their
roots seemed to want. I wanted something that would actually hold a
little moisture but truly dry quickly.

Here is the pic of the solution.
