I also have 2
Den delacourii (section Stachyobium). They’re both doing ok so far.
Can you post pics of your
Den delacourii?
Mine grows in pretty bright conditions - I would have to say the brighter end of moderate indirect.
I have them potted in small coconut husk chips. These can be grown mounted or potted, btw. Doesn't really matter.
During dormancy, they don’t get watered much. I don't really water them heavily until I see new roots. I let them dry out completely between watering.
I grow them indoors. Doesn’t get warmer than 80 F right now. Also doesn't get that cold in here because I can't tolerate indoor temperatures below 70 F
. These can take temperatures down into the 40's F at night in actuality. If you want to grow it warmer than a low of 40's F, it's fine too.
Mine will probably bloom by mid to late July or something. When they do, I'll post.
