Marie-Paule, I am finding that the plants that I have grown from seed, now one and a half years old are starting to take off. I have had a lot of causalities and I have experimented with mixes that include my orchid bark, clivia mix, bromeliad, general bulb, course sand and worsleya mixes. I have found that although they have a similar general appearance and similar looking roots they hate the worsleya mix I use, although worsleya's absolutely thrive in it. They are growing well in a general mix that has at least 80% composted bark which is great as it is much cheaper for me to obtain. I believe they like mostly organic very free draining mixes with plenty of air space and they also will not grow roots into a medium they do not like All this being said I have also found you can have everything right with a pamianthe however when they are young they are still prone to going belly up. I wish you luck and can send you photo's separately if you would like.
