This is a discussion on In-home growing: thin-leaved dendrobiums & renanthera within the Genus Specific forums, part of the Orchid Culture category; I have not done well with a few dendrobiums I've tried: Den sulawesiense x glomeratum, ...
I have not done well with a few dendrobiums I've tried: Den sulawesiense x glomeratum, Den mingle's sapphire, and Den laevifolium all got too dry and gave up on me. The first two, I tried early on, and now I'm a better orchid-carer, but I can't find those exact hybrids being sold anywhere to test them again. I got a Den laevifolium a few months ago, though, which did not work out. I think I've stabilized a little Haraella retrocalla that wasn't doing well by moving it from seedling bark into sphagnum, and now I'm feeling like trying again with some more delicate dendrobiums -- looking at maybe a Den lawesii and/or a Den sulawesiense. I got a super cool tip here about growing Aerides in clear pots and keeping an eye on the condensation levels inside the pot, so I'm wondering if anyone has similar tips about these kinds of dendrobiums.
Secondly, renanthera? Can these be grown well without soaking them? There's no way I'll probably ever do that. But -- you can laugh at this -- I had an extraordinarily compelling dream in which I found some kind of deep red-orange renanthera in full bloom, hidden away on top of a shelf in my apartment and now I want to get one. . . if I might be able to grow it.
My conditions: I have a humidity tray and a grow light in my living room. I mist heavily daily and water through the pots intermittently. Cattleya and oncidium types generally do really well for me, and everything else kind of bleeds out from that center.
My den laevifolium is a fairly recent addition to my collection, but I read that it should not dry out completely...I have been doing that and it seems quite happy..we'll see if it blooms! It is under lights. Another den that was recommended to me for my conditions is den sulcatum.
Harella likes to grow moist, and so I bet yours will do better in its new media. My harella came mounted on a stick, with just a bit of spagh, and it gets a soak every morning, and then hung back in the kitchen window. It has bloomed several times.
I've not tried renanthera...but since they are related to vandas, I am betting they'd like that "put the basket" in the neck of a vase trick...so that they get humidity at the roots w/o being soaked. They surely are pretty!
