Dried out new growth on Psychopsis Mariposa 'Mountain'
Turns out there was one victim from my 3-week absence after all. The new growth on my Psychopsis Mariposa looked a little dryish on the edges when I first got home, and it completely dried out within a few days later. When I unpotted the orchid, I saw that none of the new roots have taken--very few short roots remained, and their tips are blackened. This is not the look of a plant in recovery.
I'm almost ready to just chuck the plant. After all, my Psychopsis Mendenhall is growing and blooming beautifully. Do I need two Psychopsis plants in my limited space? Perhaps a final fungicide treatment is in order. Otherwise, I think I'll just water the plant as usual, with no special treatment (and let it either die or recover on its own).
