Lots of people grow epiphytic plants, but most of them are grown in pots, simply because that's the way we are used to growing houseplants. However, that is not the way most of these plants grow in nature. Though they might grow on rocky outcrops or even electrical and/or telephone wires, the vast majority will be found growing in trees. Why not mount some of your epiphytes, so that they grow the way they do in nature?
