I’ve known people who successfully use the ice cube method. I think it’s just a short cut to keep droplets from getting into the creases of the leaves and causing crown rot, but it’s not an ideal one. Orchids like their water to be room temp. I just get a decent trickle of water going from my kitchen tap and allow it to drain through the container while I hold the pot under the stream for a few minutes, once every two weeks. If you do get droplets on the leaves, it’s very important to dab them off with a paper towel. After watering, make sure the container drains as thoroughly as possible, to avoid root rot. I press a paper towel to the hole in the bottom.
Mine has never minded being moved, and I turn it every few days to get even light. Don’t give orchids direct light; it freaks them out. They love strong indirect light, though. East-facing windows are best, but north or south are ok too if you’re careful about positioning.
I’m not advanced enough to teach you about feeding or transplanting – eagerly awaiting further answers for these tips. I think I need to transplant mine soon, and I haven’t fed it since I got it last year. I have also read that they like being misted, but I’ve always been too afraid of potential crown rot from accumulation in the leaf creases to try – does anyone know about how best to mist?
