On the subject of Paphs...

[Fairorchids]

I have grown Paphs for close to 45 years. I find that most people. who claim that thy can't grow Paphs, are not watering them enough.

Currently I grow in a greenhouse, there I use:
2" & 3" pots: Moss/bark-Charcoal mix (65-25-10%)
4" & up: Bark/Charcoal/Perlite mix (80-15-5%)

And, I do not allow them to go dry between waterings. I keep seedlings continuously moist, and larger plants are watered heavily once a week in the winter, and twice a week spring/summer/fall.

Light dose of fertilizer every two weeks spring/summer/fall, and once a month in winter.
