Has anyone ever grown this particular type of den.? I bought one today; the canes are nice and fat, very healthy looking...it was potted in something that looke lie a coconut shell or maybe some kind of rope? The roots are growing straight down through it and when I repotted it I thought about using orchid bark and leaving that other 'thing' with it and allowing the roots to keep growing or should I remove it? Thanks guys for any help!
