While doing grafts for my recent grafting project, I came to my bag of A.s. 'Aureum - Full Moon' scions and remembered reading somewhere that A.s. 'Aureum' is "difficult to propagate". I find that odd, as it seems like any other shirasawanum as far as growth habit, quality of the scions, etc. etc. So exactly WHY is it difficult to propagate? Do the grafts not take? Are they more succeptible to fungal attack? Or is it just a slow grower, and that makes it "difficult" to turn a profit?? :-) Anyone have any insights? Thanks!
