I've read in a few orchid books that you can clone orchids by cutting the stems into 4" sections and placing on top of damp sphagnum.
I've cut a stem of my dendrobium phaelenopsis about a month ago and placed the pieces on a layer of damp orchid mix. The plastic container is closed to maintain 100% humidity. I still see nothing happening.
Has anyone tried this method with any success?
I read that too, I tried never had much success though. I even tried dipping them in rooting hormones and growth hormones none was very effective. I know it is possible though because a guy in my society brought in a den that had toppled over and the cane broke. He threw it under his deck, (as means of disposal I assume) and in the fall when he was doing yard work he noticed that the broken cane (with no roots mind you) was blooming and had a small keiki growing on it as well. He brought it in to our meeting it was very strange to see.
I have done this with variety of nobiles and kingianums. I lay a few layers of expanded clay in a plastic box in a warm place with strong bright light. With a touch of water, 75% success rate. Time frame anything from 4 weeks to 6months and counting for me.
Do a search for STEM propagation in this forum. You'll find great information.
Give it some time and it should pop out some keiki's. May take till it gets a little warmer, or may start sooner. People always give me stem cuttings to propagate cause I seem to do it quite well with many types of dendros. I just set them on my potting bench in the GH. I dip the end in fungicide and lay it on its side, no sphag or water. Sometimes I pin a cane to a slab of tree fern or cork, hang it up high and forget about it.
Thanks for the advice.
I didn't know that they needed a lot of light.
I grow my orchids with CFL's for lighting.
I have now placed my dendrobium cuttings a few inches below a 100w CFL (daylight) and will anxiously wait and hope they begin to grow.
