Thank you, Henry.
This summer I took 10 cuttings of my favorite, unpatented and impossible to buy HT mother.
I used rooting hormone.
However, of the 10 cuttings, only 2 made it. This is a mother that I want to have 20 plants of, so improving my cutting success rate is an important goal.
The article is not an easy read. But looking at the tables, rooting percentage was not very much affected by the number of nodes inserted into the rooting medium, or the number of leaflets on the cutting that is rooted. Did I understand this accurately?

I came away from that article with the idea that light intensity was the most important variable.
My comment: This would have to be balanced with the other conditions of an individual’s experiment. For example if one used the classic mason jar approach high light intensity could result in high temperature thus cooking the cutting.
On my web page I reference this article: Hortus USA: Ideas for Propagation
In tests in my yard I found that I obtained a much higher percentage of rooting from the cuttings that were placed very close to my soaker hoses that were turned on automaically every day for an hour.
For an important hard to root rose I use layering.
Hello Henry!
I was unable to open the link in the original post, however I was able to open the link you posted after Cathy’s question.
Would you re-post the original article…just give me the title/author/source and I’ll be able to find it through the A&M system.
Thanks so much!
