I have great luck with growing all my orchids but these two:
Phrag. wallisii (species - 'Dutch Treat x sell)
Phrag. Jason Fischer (Mem Dick Clements 'Rocket Flash' 4N x besseae 'Cow Hollow II' FCC/AOS.
They are potted in bark and the medium is kept moist. They spent the summer outdoors and have yellow-green colored leaves, no root rot, and get plenty of light. What am I doing wrong? They get rain water for moisture and are fertilized weakly. I'm at wits end as to why these two refuse to respond.
