Picked up my first dendrobium last night. The tag says den sugar, but cant find anything on that so i dont know. It has buds on it and what would i do to keep everything going smoothly with it? Also there is a black spot on one of the canes. Does anyone know wht it is and what can be done?
Is that black spot soft? It might be just the sheathy material that envelopes the canes blackened a bit (possibly from trapped moisture). If it's not soft, I'd just keep an eye on it to make sure it's not spreading.
