Taking it a step further then. I, for years and years, have used willow for both runner bean and pea sticks in my garden. Each year they bud and leaf even forming roots. I then take them out after harvest, bundle them up and put them away for next year. Last year I was gifted 2 bundles of ash and hazel. They dried out within 4/5 weeks . No chance whatsoever of regrowth. Now maybe young shoots, given a growth hormone might propagate but adult branches, in my opinion. Will not. Jok.
