I know how to rescue Phalaenopsis from the brink of death - put them in live sphagnum moss and they'll come good 90% of the time. Other struggling orchids often do well if taken out of their pot and mounted instead...

But I don't know how to rescue ailing Cattleya seedlings, and haven't had much luck. Mounting them often speeds their demise, as does watering...and not watering! Are there sure-fire techniques I don't know about for resuscitating troubled young Cattleyas?

Thanks
