HELP! Oncidium/intergeneric emergency :(

[rbarata]

These concepts are basic knowledge of chemistry but previously I never though about it very seriously.
But now that I'm facing what seems to be (I hope) nutrients deficiency, this has caught my attention.

Although, as Ray mentioned, there are no information suited to our orchids, this information gives us an idea about how each nutrient can behave.

My point. And, it has been many, many years since I had chemistry (class). 😁

So do I but before going to Uni my study area was chemistry. After all these years I still remember something...not much, but enough for a day to day application.

Probably the same here. I often joke that I have to shake my head sideways to make room for what I'll learn that day. Lol

Hi Princerobby,

With all due respect to the brilliant messages above, I would ignore them all. They didn't read your message very carefully.

1 Your plant isn't getting enough water. I don't know whether this is because it has mostly dead roots, or you aren't watering enough. I suspect the problem is the roots are mostly dead.

2 Some complex Oncidium hybrids can't take much heat. The temperatures you report are too high for some Oncidiums sold at supermarkets and hardware stores. Any chance you have a photo of the flowers? If it's a plant that can't take heat, this is how they die. I think this is the problem with your plant, especially because you have other plants you say are doing OK.

3. So it comes down to which plant this is.

4. With your temperatures, you might consider Cattleya, Dendrobium or Phalaenopsis as easier-to-grow plants.

5. The stuff posted above by other people is critically important, but not to you and not right now.

We went off course at the beginning. Apologies.

I was able to dig up this photo of the flowers from the first day I got it. They're small, about an inch or so in diameter.

And yes, I did find it a little weird that my other 3 oncidiums are doing just fine. One has pseudobulbs that are nice and plump and is actually growing two new growths. The other two are twins, meaning I think they actually came from the same plant. I say that because when I bought them, they were potted together but when I repotted it, the two bulbs actually very easily separated so I was surprised with two new plants instead of one.... but that's a different story haha. But anywho, both those plants have new growths forming as well.

It's just this one plant that seems to be having the exact opposite experience. The other 3 have new growths while this one is starting to shrivel up

As much as I want this plant to live, I just need to know that it wasn't my fault ^^'' Or if it was then how I can avoid it next time

In "orchid life" two months is not very long. If it has been repotted, keep up the watering and let it settle into its new environment ( no more unpotting to peek at roots). The existing pseudobulbs will not plump back up, probably. But in time the plant will produce a new growth that gets is strength from the old until it grows some new roots. Orchids teach patience.

Posting photos from a Google drive doesn't work here. I suggest you look at this thread:
Tips for posting Photos

I did figure out how to see it. It is probably something called Oncostele or Colmanara, which is usually a very tough and easy-to-grow group of plants. I don't know why you're having trouble.

At this point I would try to keep temperatures moderate, and not let the roots dry out. There is a chance it will make a new growth, and slowly recover.

Those who want to see the plant - copy this text, except leave off the letters IMG. Paste the text into a browser URL box and you will see the photo.
