I have two Ludisia discolor that are growing out of their pots. Previously I have potted them in a mixture of standard orchid mix (bark,etc.) with peat moss, vermiculite, and some charcoal. They have done well but is there a better mix?
When I bought mine, it was in pure shag. I repotted it into a third potting soil, a third pearlite, and a third peat moss. I've also tried sphag and pearlite 1:1. All three seem to work well.
