Ursula, wonderful Epi longipetalum x Laelia lundii. I love it. What a strange growth pattern on that Dendrobium. I can see why you bought it.
Ken, there are so many different types of Dendrobiums that I could not give you a blanket answer. Let me just say that I grow most of mine in baskets, not pots and I agree with the mix recommended by Tarev for most of them. Other types do very well mounted on wood.
