What and why is it growing on my Nobile Type Dendrobium

[Sandra75]

My Dendobrium flowered back in May-June. I thought it was going to reflower again but this doesnt look like flowers.

How do I have so many new growths on a single cane?

Is this a good thing? It did spent the whole summer outsite.

A lot of mine do this too. Personally, I think they look a bit untidy so I wait until their roots are well developed, twist them off the parent and pot a bunch up together. I either keep them or give them away to friends once they’re established. You can also leave them on the parent and they’ll eventually bloom there too.

Just to answer your questions, yes, I think this is normal and the growths are keikis. They’ll all eventually put out roots.

I let the roots get to at least two inches before separating them and I’ve found separating them via twisting rather than cutting causes less trauma to both the parent and the keiki. So far, the keikis I’ve separated have bloomed in year two.

My personal taste is a bit different - since keikis can also flower, I lean toward an untidy plant with a chance of more flowers. (But then, my yard is a bit of a jungle, too) So there is no "right way" on this. Just enjoy the flowers, leave the keikis or separate them as makes you happy! But they are normal.

Isn’t the excessive growth of Keikeis due to too much water and fertiliser over winter?

My understanding is these nobile types require a dry winter if you want flowers. Keeping them growing through winter leads to abundant keikeis and few flowers.

In plants that can grow keikies, but normally don't, their formation is often an indication that something is amiss with the culture - it can be a secondary means of carrying on the genetics.

As the OP is in the northern hemisphere, the winter rest thing isn't in the thinking yet.

I am not a grower of dendrobiums, but the yellow color of the cane seems off to me. Hopefully others will chime in with more knowledge.

Sandra, can you give us more info about your cultural parameters, such as the light levels, potting medium, frequency of watering and feeding, etc.?

It caught my attention too...by this time you should have new growths already.
Do you have them?

No, I barely fertilize in summer. It had tones of flowers in spring. This is why I asked if this many in a single cane is normal.

My plant stayed out all summer. At some point it had direct sun light but now sun is lower it doesnt get direct sun light. Its in sphagnum moss now in large pot. But i got small bard and smaller pot to repot. I water when top sphagnum moss is drie. Nothing much. Now its home due to the keikis...not sure how cool I get can plant to. And theres no new growths, just the keikis on that single cane.

What can the yellow-ish colour be a sign for?

No new growths, just even a sign of new growths. Just those keikis.

[rbarata]

The yellowing of the cane is a sign that it is almost finished. After that it will dry and die.
I suspect the keikis, as Ray sugested, are replacing the new growths, i.e., that's the way the plant found to leave its descent because it seems to be dying.

The cane might take a while to die...until then, keep it in a humid and warm place too see if the keikis' roots start to grow rappidly.

There is another technique that I would try if the cane dies faster than expected. See the vids bellow:

Is it the cane thats dying off or my whole Dendrobium?

Makes sense now why so many keikis on a single cane
Do I have to water more often now that the cane has those keikis?

[rbarata]

Is it the only cane?
