Just in case anyone was confused about where roots form opn a cutting:


No it wasn't laying horizontal. It was upright in the proverbial 20 oz. cup.

Jon,
 
What kind of cutting was that?
 
Cecil

So if mold has damaged/killed the nodes but the stem is still green, there's a chance of still saving the cutting by making a slit on the stem between the nodes and planting it?

I'm having a lot of trouble with the Capela and Black Madiera cuttings. I really want these to grow. So maybe I'll try this.

The point was, they root where they want to - not that I did anything to encourage this particular growth pattern.

Cecil,

Don't remember, but it is not the first time I have seen this, by any stretch of the imagination.

Sue,

Cut off the top, if it is more than moldy, that is, already decaying, till you get down to good wood, and "replant"

Sue,
I would have been interested in answer to your question "if mold has damaged/killed the nodes but the stem is still green".
I hope someone with horticultural knowledge clarify this point if there has to be a nodes for shoots to sprout from.
It is my observation that shoots need a node to develop where as roots can take place across the cutting.

Good point Akram. I think you may be correct.
Sue

I have never seen vegetative growth from any place other than a node, on a cutting. However, it you severely prune a tree, it will sprout new growth from large limbs. BUT don't know if that growth is from an unused node/bud, or if the plant generates new growth from a non-node cell. Even IF a mature tree does not need a node, I doubt that a cutting has the same ability - it may be a factor of less energy reserves (lack of root mass) or ?
