Orchids like the slow release of water from ice cubes, but not the cold. I didn’t know you couldn’t just water them like normal if they’re planted in orchid bark (you have to soak/drain them). Mine died of dehydration even though I watered it frequently. But I’ve since planted all mine in sphagnum moss, and that helps a lot so long as you don’t over do it. I’ve had a lot of success with this and have gotten mine to rebloom several times!
