I didnt go too deep on the stems. Barely exposed the white. More like really really really light green. I think I messed up with making the openings of the containers too small... I had all sorts of trouble getting em in there. Lotsa bruising during the install. By the 3rd one, I had it kinda figured out.
Next time will be better for sure.
After reading this tread, i wanted to try...

I scraped slightly the branch with my thumbnail and I banded with a Riot Root cut in half

Bended with some cellophane

Hope this works.
Lightly scratching it won't work. You have to remove more material than that, all the way down to the white latyer all the way around the branch. I had a bunch of failed attempts this summer from not going deep enough on the branch.
