Again Kevin, WOW!.....550 plants. Do you plan on coming back to the states to live? What about all your plants? I'd have a hard time leaving them, really.
Yes, I cut back the roots on the one orchid whose name, I have no clue. It's huge and was completely root rotted. The plant itself looks healthy but the roots were disgusting. Soggy, practically falling away on their own when I touched them, limp. I carefully removed all the bark and cut the roots up to maybe, 1/2". The one thing I didn't do though which I later found out I should have done is rinse them under water and use a root stimulent but they were so water logged, perhaps it was best that I didn't? Is there something you suggest I do before I have to call paramedics?
I can't get over 550 plants. That would be a sight to behold.
