What is this growth?

I got this No ID Oncidium about 5-6 weeks ago. The flowers died several days after I got it. Anyhow, this second spike has remained and seems to not be growing. I repotted it right after the flowers died.

What is the spike? A keikei or flowers?

That certainly looks like a spike.

Oncidiums are generally picky about re-potting; and can take a while to settle into their new homes. The spike may just atrophy or it may not. Just monitor it closely.

Looks definitely like the flower spike. The re potting when in spike may have slower it's growth, you should not usually repot when your orchid is flowering or in spike, do it after. Also, I see bulbs seems shrank, which means it would use some longer water soaking for them to plump again.

definitely a spike!

Well I hope it doesn't whither away. Unfortunately, the plant was in dire need of repotting. One of the pseudo bulbs was rotting from the top down and it looked like the plant was planted too low because a few of the bulbs were half buried. So I ended up having to slice off the bad bulb and then while repotting I found that another pseudo bulb had been completely folded underneath and was well into rotting territory.

The bulbs have looked like that since I got it. I have soaked him, and generally I don't water unless the dowel stick comes out dry. I ran out of bark during the repotting because I thought I had a another bag so he is now in sphagnum moss.

Because the repotting was traumatic I don't want to switch until I see growth. Does this need more watering or once the bulbs have shriveled do they remain as such.

PS the pic is upside down because it refuses to cooperate.

Howdy
must be patient with oncids in that their new roots come after a new growth has begun, and is about 1/3 to 1/2 grown. Moss was okay in this situation.

I've seen much worse recover.
Be patient, and attentive.
Have fun

Pbulbs help the plant retain energy. As the plant develops new growths, the parent bulb will use its stored energy to nurture these new growths. It will shrivel and stay that way. Oncidium like to fill its pot to the edges, but they don't like to have too much pot, so the recommendation is to pot half a size larger.

Once your plant gets over a dozen Pbulbs and you do not want to continue increasing pot size, you could divide the plant and get two or more plants. The guideline for dividing a plant is that each plant you end up with should have at least three Pbulbs--as these will help the new plant establish itself.

Depending on your plant's culture and your environment, soaking a newly potted plant is a good thing to do. Once it is established in the pot, you might consider allowing the plant to come to almost dry, then water it again. In the winter season, I have allowed my plants to come completely dry, but I have a room humidifier that circulates moisture and an oscillating fan to create air movement. I do this to ward off the three orchid horsemen of death: too wet, too cold, and stagnant air.

posts don't mean anything, most of those are because I love browsing other people's photos of orchids and commenting on those I like
