Got a noid oncidium a few years ago at trader joes - one of my first orchids - it was probably the plant that kept me going in orchids as it bloomed profusely every year while other orchids either died or simply did not bloom for me
Was turning in to a nice sized plant when last spring for some unknown (to me) reason it went down hill fast.
No good roots and every part of it dying.
I was left with 3 hopefully good enough pbulbs - I put plant, pot and all in an old fish tank with damp peat and within a couple months had new growth starting.
First pic - the 3 hopefully good enough pbulbs
(the rotten looking parts have been there since the near death experience and have not gotten any worse)
Second pic - last years growth/pbulb
third pic - a spike!
This is the first orchid I have been able to 'save' once it started going downhill - and really didn't expect it to bloom this year - so am very happy!
