Q: What is the best thing to plant Phalaenopsis orchids in?
If you are in an area that is very cool or gets lots of rain, I would suggest you plant them in a mixture of charcoal, pebbles, and tree fern bark. This way your 'phals' can withstand the rain (not the sun) and still survive as the water just runs right through the medium. Be warned, though, that with this medium, one has to water often.
The alternative choice is spagnum moss; this is the medium with which most people have a problem. In this case, feel the moss and when it is 3/4 dry you water again.
