a short note on s.cropping: the main 'trick' is learning how to crack the cambium(inner skeleton),without breaking the vascular ring(sap vessels). pinching and twisting, or repeated bending to-and-fro(less stressfull), without snapping the damn thing, and cussing your brains out! it takes practice to know just how far to push 'em; but it's definitely an essential skill.
