Spanish moss is not a true moss. It is a bromeliad which goes by the scientific name of
Tillandsia usneoides.
An example of a bromeliad is the pineapple.
Bromeliads are flowering plants, not mosses. Mosses don't produce any kind of flowers at all.
Here's a little tidbit many people don't even think about with pineapples...
The whole pineapple fruit you see in the market comes complete with a new plant. The leaves on top of the yellow fleshy goodness we eat, that's a new pineapple plant you can cut off the fruit and grow for fun. Pineapples don't come from trees people.
I recommend growing the "Spanish Moss" separately from the orchid.
Yes, you heard me right, grow the "Spanish Moss" separately, as in that clump of
Tillandsia usneoides is still very much alive.
Tillandsia usneoides needs fairly high humidity to do well. They also like some air movement, (doesn't have to be too heavy, but a nominal breeze is fine).
Moderately bright indirect light for the
Tillandsia usneoides.
They grow in intermediate to warm temperatures.
Water 1 - 2 times a week.
The flowers are tiny and are yellow-green.
These do not bloom very easily, nor do they bloom frequently in cultivation. But they have cute, fuzzy, grey-green tufts of soft foliage.
This link will show you what the flowers for
Tillandsia usneoides look like:

For the Phalaenopsis, if it is grown in Sphagnum moss, (Sphagnum is the genus name of the moss, and yes, they are considered to be true mosses), then remove the orchid from the pot and change the media out to large pieces of fir bark.
This is what live Sphagnum moss looks like:

Dried and cured Sphagnum moss looks like so:

If it is already planted in bark, just leave it alone until you see that the bark is starting to deteriorate. How you can tell if the bark is deteriorating is when you start seeing little particles of decomposing wood draining out of the pot pretty regularly.

Btw, before I started growing orchids, I was growing bromeliads in the genus Tillandsia.
