That Keiki looks promising. I know it must've stopped all root growth. Just wait and don't let it die. It will start really good root growth in a few weeks.

So, by mid November, all the flowers were gone. I had it hung on my window blind for a few more weeks. only misting every morning as I had been doing. (although I was wondering if it would have absorbed any since there were no living roots at all) I did any way.

Then the first week of this month, I took it off the blind, cut off all the dead and dry roots, cleaned it wth water, choped up into four big and not so big pieces, and put them in a clear plastic case.

I even ordered some high quality sphagnum moss to use as bedding material for these chopped up canes.

Then I totally forgot about it until today as I was reorganizing kitchen cabinet (dark and warm but dry).
I took the plastic box out and took a close look at the canes.

Lo and behold! There was one tiny new growth emerging and two more coming on the same cane.
The other parts have small swelling on a few of the nodes. This is quite something! I guess I will name this plant, Tough Pink.

I'm not sure if I should move it to a moist sphagnum moss setting or leave them as they are. I'm afraid of fungal attack on delicate little growths.
Does anyone know if placing these in a physan 20 dilution will harm the little growth?
Maybe I should have done it before the little growths appeared. hmmm not sure how to proceed now.

By the way, the two keikis are still alive, but not doing aynthing. I believe they will stay like that until the spring when the weather gets warmer.

It may take a very long time to actually get recognizable plants but just wait. mist daily and that's it. Use some super thrive if you have around as well. The same happened to me. If you are successful with this, you'll be rewarded by many new plants.

It looks like this dendrobium truly deserves the name Tough Pink

Two of the little growths are turning into little green plantlet. I see the leaves and roots forming already.

This particular hybrid has a great potential as far as flower production.
The store I got this plant from back in August had two, one of which I brought home.
The other one was too expensive for me, but it was spectabular with many pbs, a few of which had keikis growing their own flower spikes. It was quite the show. I should have taken pictures.

Now that I have three little growths going and I have two bigger keikis, I will throw the other chopped up canes.

I think your Keikis need to be in a much smaller pot for now. 2 inch pot max. Dens like to be very root bound. It also allows the media to dry quicker. I'm afraid if you leave them in the larger pot they will rot like the parent plant did.

I was able to revive no id dendrobium by putting rootless cane into ziploc bag with moist sphagnum. It was in warm place but not very bright light. I was opening bag every day to let some air in and to pick on the progress. Cane still had some leaves, they quickly yellowed and fell off in the bag. Keiki appeared after two weeks close to the base of old cane. I waited until it had some roots and planted into chc still attached to the old cane.Now keiki is fattening up and looks pretty good with lots of roots, but it is still attached to an old cane.
Your old canes have no roots and leaves, but don't remove keikies from them , plant them together.
Good luck.

Terri- They are not in a pot if you look at the pictures.
They are simply placed inside an empty plastic box. nothing will rot in that empty dry box. lol

orchideya- I'm not sure if you read all the posts in this thread, but I've had this dendrobium hanging with no roots for months. leaves all turned yellow and fell in november. now I see the little growths emerging from the cane. I meant to place them on moist moss but I somehow never got to do that. I just threw them in an empty box and they are just surviving on their own.
quite amazing to me. what life is...
They are really small at the moment but growing roots (one or two very small start on each) already.
I agree with you on leaving the small plantets on the old cane. They are just so small and I dont' want to hurt them. lol

I was referring to post #10 in this thread with the 3 pictures of the Keikis in clay pots.

Your Dendrobium is in the section Phalaenanthe, and is somewhat drought tolerant hailing from Australia, or areas near there.

It is naturally a lithophyte, rarely growing as an epiphyte.

It normally does have a seasonal wet/dry cycle, but most people don't observe it in cultivation (and apparently it still does fine).

That should kind of explain the durability of your Dendrobium.

It looks like a D biggibum hybrid. These appreciate a dry period during winter and drop their leaves. You may get lucky trying to sprout with the mature bulbs however dead sections at the bases usually spells death for the psuedobulb. The Keikis will produce flowering size plants within 2-3 years so good luck with the keikis.
