I mounted my first 2 plants. I am sort of experimenting and I have 1 sick plant and 1 healthy plant. Both are Phals. One was rotten when I bought it and all of the roots are gone except for 1 tiny root that is new and about 5mm long. I mounted them both on cork bark with sphagnum underneath for moisture retention. So here are my questions:

1) I have read much on "dunking" the plants for watering. Does this mean the entire plant, including the leaves? I have, so far, been watering them in the basal/root area only.

2) The phal without roots: is there a product I should use, a hormone or something, to stimulate root growth?

Thanks, in advance, for your help!
