I was thinking the same thing, if they are budding from the roots then they should be able to propagate from that method. It was weird to not see anyone ever talking about it.
If you ask my therapist and wife, I have enough cuttings. I stand firm in my opposing belief. I have struggled to root cuttings from this plant, although this is a successful air layer.
I was a bit bummed when these lower branches died this spring, but I am happy to see it budding again down low. With that lower left branch gone I lost direction, so here it sits. I very well May replant next season just to see what is going on.
Always always, thanks for sharing your knowledge!!!
