Ludisia Discolor growing media? Repot?
 

Do you think I should re-pot?

I've just been given a recently-propagated ludisia discolor (jewel orchid). The plant is small, about 5" high with 4 leaves that are about 1.5" long and ¾" wide. (4 cm x 2 cm)

I've read online that this orchid should be grown in soil. However, it is currently growing in 100% sphagnum moss. The moss is loosely packed. I have read that jewel orchids like warmth and humidity, but I'm wondering if 100% sphagnum is maybe too much moisture. Should I repot into african violet mix (which I've seen suggested online), or a mix of soil and sphagnum? Or just leave it as is.

Loosely-packed sphagnum has always been my "go-to" for those.

I suggest that you stop thinking in terms of "too much moisture" for any orchid, and think instead about "too little air".

Loose sphagnum is no issue until it starts to break down and no longer be "loose".

I grow it in SH

In nature they grow in loose leaf litter under trees, not in soil. A lot of "terrestrials" are like that. They will often crawl across the surface of moss or other light, airy media. Soil is too dense/not enough air.

Don't soak the sphagnum. Just run water briefly over the top so it winds up a little moist.
