3 new orchids, I don't understand what to do.
Bought these 3 new orchids today at a local trader joes, these are mini orchids, oncidium without a name tag, another oncidium as well, and a cattleya. All 3 looked great in store, when I got home to repot them into bark medium from the moss they were in I realized that the moss was really dry. Orchid roots were also very dried and appear to be dead. I placed them into bark medium mix with some charcoal and perlite. I also watered them and fertilized with 20-20-20 fertilizer, and added superthrive (hormone with vitamin mix).
any suggestions on what I could do?
