The only Orchid that I don't water outside is the one in a tall glass cylinder. Once in a while I take it outside, flood the pebbles in the bottom with water and then turn it on its side and let the water run out.
Last year's bloom.
I keep thinking about taking it out of the glass container and repotting in a regular orchid pot in orchid medium. I wonder if after all these years of confinement it might die of shock? Or would it take hold and start to grow?
