Dendrobium Lost All Leaves / Keiki

[King_of_orchid_growing:)]

I have doubts that this Dendrobium is a deciduous Dendrobium. If it is a deciduous one, it is not one that goes fully deciduous, but rather, it would be considered a "semi-deciduous" Dendrobium.

It looks a lot like a Dendrobium hybrid that is either in the section Phalaenanthe or section Spatulata.

Dendrobiums in this section are predominantly epiphytic Dendrobiums.

If it is in section Spatulata, then it would be considered an "evergreen" Dendrobium. Should it be within this group of Dendrobiums, your Dendrobium is not healthy. If you want to know what a healthy looking Dendrobium in the section Spatulata looks like, as an example, here's a pic of my Dendrobium tangerinum, notice the canes are not shriveled looking:

If your Dendrobium belongs to the section Phalaenanthe, then it is semi-deciduous, and some canes will drop all of their leaves, while others will still retain them.

Again, the canes should not be looking shriveled for these types of Dendrobiums either. Especially during the summer, when they are in active growth.

Dendrobiums in this section actually do have a rest period during the winter, although, people tend to ignore it in cultivation with this group of Dendrobiums.

What's more is that a good portion of Dendrobium species in this section are actually lithophytes, not epiphytes. They can be grown in a mix of some small grade bark with some granite pebbles.

Please post a pic of the roots to your Dendrobium. I really doubt that your Dendrobium has a strong enough root system to support it. Being that it is summer in the northern hemisphere, (summer is practically when all Dendrobiums are in active growth), it should be very clear which roots are dead, and which ones are alive and still growing. You should really be seeing green root tips on a large number of the roots on this orchid already, signifying that the roots are actively growing. During this part of the year, (summer), there should be no confusion whatsoever as to which roots are alive or dead.


The Dendrobium in your pic doesn't look like a "Nobile type" of Dendrobium to me. There are no physical characteristics that I can see, where it screams "Nobile type".
