Sometimes orchids simply don't do well. Since I have only grown these plants since last summer, and the 9 month old one is the longest I have had one, I wouldn't even venture a cause of your plant's demise. I think everyone deserves a second chance though.
Let's just call this "Paying it forward". I have had plants shipped to me from ATP members, and some of them would not even consider doing a trade or having me pay for even the shipping. There are probably few sites that have the kind of folks that we do here. We are all lucky in that regard.
Oh, you are not only getting my last Eurychone but also my last round cedar mount. I think you will like the mount.
