What is the best potting mix for a Phalaenopsis Orchid?

I have one in moss which seems to always be slightly moist, and one in bark that seems to always be dry. the one in the bark is turning dark green from the bottom... it seems dead.

What is the best potting mix for a Phalaenopsis Orchid?
Spagnum moss alone holds too much water and will eventually rot the roots.



We use equal amounts of fine-grade tree fern and charcoal plus some perlite or lava rock.



You can purchase ready made orchid mix at garden centers which works fine.



See source for more suggestions.
Reply:the long fibered sphagnum moss is the current favored media for phaels.

it should be allowed to get toward the dry side between waterings.

the bark media is fine if you are doing better with the orchid in moss feel free to change over.

either of these media will break down over time and it is important to rejuvinate when they start to break down. Do this preferably when the orchid is in active root growth phase and take care not to damage the roots,

they don't have to all be under the surface.



what is turning green?

if it is the bark itself .....%26gt; either the bark has been kept too wet, it is draining thoroughly, the bark is old and rotten.
