I've had epiphytes before. Supposedly they don't need watering, but then when I read the instructions, it says I'm supposed to drown it and then let it dry out. Tried that once, and killed it off. So now I've got an epiphyte as a Christmas ornament. It's in a 4" glass ball with open sides, sitting on a little bit of driftwood. Do I water it? Soak it? I guess I don't put it away with the ornaments. How much light/warmth does it need? Do I hang it in the (full shade) window? If it wants warmth, will the window be too cold in the winter? Do I leave it in our (dim) living room?
