Hi all, please help with my problem. I bought this Cattleya cutting with no roots two weeks ago. When I bought it, the whole orchid was really green and healthy and I did not see even a little black spot. Last Friday, I noticed all the eyes became black. The black color seems to be spreading now. I already removed the covering of all the eyes so I am sure it is not the cover. I am not sure if it was because of watering but I was really careful with watering or maybe virus or bacteria? What can I do to save this or it can't be saved anymore because the black started from where the root grows and I just have to throw it away or cut it into individual bulb starting from the healthy tissue? Please help. Thank you all in advance.
