Propagating Japanese Cherry trees
I have a few weeping cherry trees (Prunus kiku-Shidra-Zakura) that to maintain their form I need to prune. Ideally I would like to propagate them using these cuttings.
From what I have read they can only be rooted via air layering or softwood cuttings. It is too late for the latter (though I could wait till spring). Has anyone airlayered successfully or rooted cherry from hardwood cuttings?
