Deeewd, just ask Sir Bot's how batshit I went when he restored them!
:slaps: :roflcry: .... they are as critical as adjectives in a text-world, IMO!
.... Shweet! I shall festoon your thread with odd beauty then,...
...LOL! Noods, I still am not sure what you mean by stems and branches... Many orchids have neither! ( well, at least the body of the plant... flower spikes can have them-- later I'll talk about and show the two main growth patterns in orchids, and you'll see what I mean).... Big fat fleshy leaves,.. sounds like a Phalaenopsis (got a pic?)...new leaves emerge at the crown, one atop the other,..flower spikes and root emerge from the sides,...These are true epiphytes, and those fat roots like being in the air as well and in media,...is it a lower/lowest leaf? If so, likely it's just shedding older growth-- normal,... if it's a high up, a prime one, likely it's rot,... orchids are usually great at dumping bad leaves before the rot spreads, but it's okay to cut it at the base, and let it dry and seal for a few days,... sulphur powder/spray would be fine on the exposed cut to help! What's it potted in? Root rot is the #1 killer,... I see lots of cheap sphagnum moss these days, instead of the course bark (more $),... this is okay for younger plants and those in that optimal nursery environment, plus they get transplanted regularly, long before media rot sets in... and that's the problem with home env. conditions with that moss... tends to hold too much water too long, poor draining, smothering... recipe for eventual root rot! As for what to feed them, honestly, I've never used that much organic type stuffs with them, at home or at the nursery... I think because of the enhanced biological activity, it tends to decay the media much faster, and can take the roots with it...so using synth. nute's is preferable for them,... for epiphytes and their kin, the usual microbial relationships are different than with other true soil terrestrial plants,.. no soil herd per se growing on bark, or rocks, etc.,... they are many that cannot survive in a pot, and must be mounted on something... So, let me know what it's planted in, and pick up some orchid food, something balanced for this type orchid... Grow More makes good stuff, yellow 20-20-20,... LOL! or, continue with the experiment! pH is fine, but really hard water can cause mineral build up burn after a while,...occasional transplanting will be needed,.... I have several, cloud forest types, that would croak in a week with even modestly hard water, others can endure quite a bit! Orchids often defy generalizations, the whole family is rife with exceptions, such is their diversity....:slaps: -taxonomy is a nightmare!
*** Okay, let's see what's in the photo stash here already,... thank you Noods, I hope you enjoy!
Dendrichilum spp.--> zillions of tiny flowers
One of my true prizes! Cleisocentron merrilianum
roflcry: whadd I tell'ya about their names!) ... blue, for some odd reason, is the rarest color by far in orchids,... though lately I'm seeing dyed ones-- Phals'-- of blue and other phony colors! :no: this here's the real deal!
