Potting medium for hippeastrum epiphytes?
Besides h.aulicum, which species are regarded as epiphytic, and what potting mediums have produced the best results for you? There doesn't appear to be a concise listing of this information.
I have year-old seedlings of h.aulicum that started well in a 'parfait' of scoria and perlite plus some organic potting material, but are ready to repot now. I'm inclined to use either orchid bark, or straight scoria in a terra cotta pot.
What have you used for evansiae, iguazuanum, parodii, neopardinum, etc?
