I can re call "Sound of Music " .all the children climbed on the trees and sitting on them and singing and waving.
I think this is a new innovation for orchids growing here.
Because the hard wood is very very expensive due to carpenter work and its very rare.Therefore we think twice when we use wood for orchids. And due to heavy rains woods decay without delay.
Some people mount them on live trees like coconut or mangoes but do not cut them .
Some people use these cement posts for dendrobiums too.
I am sorry we do not have winter season here. I never happen to think about it.
And for that you can use 4 foot posts planted on cemented pots . Those are movable.
Thank you and to your wife. She can have posts full of flowers in her living room.
Another suggestion is can use those concrete posts horizontally and dens grow on them without any ceiling .
Okay.
