Hello,
English is not my native language, so sorry for spelling errors.
I'm trying to propagate my Dendrobium Nobile White. On 16 November I have cut 2 old pseudobulbs into smaller pieces and put them in flower foam. 1 of the pieces has sprouted a keiki and I hope that some others will follow.

16 November, cutting and putting the pcs of the pseudobulb in the small greenhouse.



I had 15 pcs and a lot of hope.



27 Januari, the first keiki is a fact.



It's now 5 Februari and it grew a lot.

I hope the rest of the cuttings will follow.
Any advice of info on this methode of multiplying Dendrobiums?

Have fun.

I have never seen this done! It sure looks very promising!
How much do you water this set up?

The big green block is used in flower arranging (cost about 1 or 2 €) and you make it wet and it keeps wet a long time. Then it's up to checking it every month or two if it's still a bit wet. It doesn't need to be soaking wet but just wet enough to keep the humidity high. The water is not needed for the cuttings. You can also use moist spaghnum moss and lay the cuttings on the moss, but this green block is cheaper then moss. A must is sealing the ends of the cuttings with wax from candles to prevent intrusion of bacteria and fugi and loosing moisture from out the cuttings. Just melt the was, dip the ends in it a bit and ready.

Thanks! This is something to consider !

What is actually happening Chris is that you are awakening old flower spikes that did not bloom before OR you are creating new plantlets, "keikies", to form along the pseudobulbs. It is a novel approach and I have never heard of it being done this way. Looks like you will have some success. I believe keikie means baby in Hawaiian.

But in terms of growing Dendrobium nobile, species or hybrids, and getting them to bloom properly is to water them like crazy and fertilize often when in active growth. Then once you see the 'terminal leaflet form', you cut way back on fertilizer and reduce watering a little. Once you see that terminal leaflet form, some growers used to think that cooler nights would help produce more flowers. That is a myth that Florida growers debunked. In the Naples area, friends of mine, rarely have a cool night. They believed that cutting back on fertilizer once the new bulb is mature coupled with reduced water does the trick.

I saw it happen this way somewhere on youtube and decide to try it. If you've not flowered spots on the bulbs, I think they will flower, then you've to rip of the flowers.
Also, I only saw it been done with the Nobiles.
My Dendrobiums bloom every year and I keep watering and fertilizing continiously once every week. The potting mix is half mid size bark and half spaghum moss. Keep the air flowing and keep the roots humid. But I will certainly try to cut down the furtilizer once the new bulbs mature and try to reduce water with a few of them as test.
Thanks for the info.
Below some pics from, I think, last year.

Oh my! 💕💕This is very pretty!

Oh, you are very welcome Chris.
