Dens with no roots

[aries23]

My dens had no good roots so I trimmed the dead ones off and bagged them with a moist paper towel. After a few weeks I was going to trash them yesterday because I saw white fuzzy mold and smelled horrible. I decided to check them out anyways. So on one that still had green leaves started to grow a green root. The other one lost it leaf and turned yellow. So while I was triming more dehydrated pieces at the bottom by mistake I removed the root how disppointing !! I wonder if this plant will give me more roots or not? I cleaned them nicely and see if this will happen again!

Just my 2 cents about this...

I think that you have to aim on new growths, not on new roots on the existing canes. The chance you get new roots on existing canes is small as I found out myself.

What kind of Dendrobium are we talking about?

This is what I did with a Dendrobium kingianum. Made multipe cane divisions from the plant as I wanted new growths. The more divisions, the more new growths was the thought behind it. It worked. I layed the divisions (without roots) on barely damp Sphagnum moss and waited months for new growths and new roots on the new growths. When the roots were a bit longer I potted it up in moss (normally I only use plain bark) and kept it moist again (but very airy!).
Den's don't dry out very rapidly and if you make sure it's in the shade the canes can survive without being watered for a long time.

I overwatered my first Dendrobium Phalaenopsis type and it lost almost all it's roots. I potted it up in the smallest pot I could find and made sure it couldn't wiggle in it's pot by using a stalk and cable ties. I only sprayed the surface of the medium once in a while but I don't think it did much for the plant. It produced a new growth and when that one started roots I kept spraying the surface. After my experience with the Den. kingianum I prolly should have done the same with this plant (but I didn't know better).

Both Den's now have several new growths and are filling their pots with roots.

Den's are pretty hard to kill. As long as the canes are alive you can nurse this plant back to health, but it could take a while before it flowers well for you. The Den. kingianums only had 1 spike on each plant, despite it had lot's of new growths. The Phal. type Den. did better and bloomed from several spikes but that one wasn't in the disastereous shape the kingianum was when I purchased it from eBay.

To be honest, that little kheiki (if it's a kheiki) may be hard pressed to survive. There's a greater chance that it may not make it than survive.

Time will tell. Keep it around and see.

I Agree with Blueszz, you can nurse it back to give you new growth. I would however not seal the bag completely so there is some air circulation to help prevent fungus.
Good luck.

Do not put it in a bag. It depends on what kind of Dend. you got!
Phal, Lautoria and Antelope type are warm grower and frequently send out new roots from existing newest cane.
If your Den is nobile or formosum type, you have to wait till next growing season when new growth came out. That will be your only way of getting new roots. Bare in mind the new cane maybe a little smaller, but should recover back to blooming with in two season. They are harder to kill than the above type, b/c they goes into winter rest anyway so.
