Hello catttan. Thank you for your reply. I must say that here in southern California (U.S.A), I am able to give it the conditions it needs when it comes to water and temperature. Unfortunately, I feel that when it comes to the growing medium - I'm at a loss. I have a Den. Hainanense which has bloomed every year since I bought it, and Im under the assumption that the two need similar growing conditions. I once read an article saying that Den. Hancockii was a ground dwelling orchid, and it made me wonder if the reason my orchid wasn't doing well was because of the growing medium. For this reason, I wanted to ask around to see what growing medium would be best for this orchid. On one side, I'm loving this orchid because it's challenging me. On the other side, I'm getting frustrated, because I want to see it thrive and not just barely survive. Thanks for taking the time to reply and for your ideas.
