Problem with Trichotosia dalatensis (Eria dalatensis)
 

I got the species five months ago. It's mounted on cork bark: temperature 75 - 88 F; humidity 65 - 80; watering once a day. Recently, the plant doesn't look happy: its leaves turn to yellow and become rotten one by one. What should I do? Any ideas? :(

Increase air movement, and a little less watering. I haven't had good luck with this hairy genus, but they sure are interesting! Do you have pics of the plant in trouble?

Hi, Mahon,

Thanks for your reply. :) I'm so glad with your suggestion about watering and air circulation. Here are the pictures I took this morning:

About 20 leaves have dropped within a month.

I found some online reference about Trichotosia dasyphylla:

Temperature: Cool - Intermediate (15-27°C)
Humidity：50-70%
Light: Low
Water: Evenly Moist
Season: Spring - summer

Growing: Mounted on tree fern, cork or hard coconut husk suits this miniature species as well as high humidity, good air circulation and constant year round water.

:scratchhead:

Yeah, this is one of those weird ones in this genus! ;)
It just looks like the plant needs to be a bit drier. The moss may retain too much water, which can slowly rot the plant. Overall, the plant looks like it's definitely going to live if the conditions are changed a little. :) Increase air circulation as much as you can, and if you have a cool spot in your greenhouse, stick it in there.

Thanks for your reply. I'm going to water it less and give it more air circulation, only to see what will happen to it. Thanks again.

Who sells those? I'd like one.

Trichotosia dasyphylla is now a rare species even in its habitats.
In 2005, it (in spike) was available from Oak Hill, but not now.

Due to various environmental reasons, Trichotosia dasyphylla is listed as an endangered species in China, Viet Nam and several other habitat countries. The relevant purchases out of those countries are difficult.
