Though some of these branches may appear super-cropped, only one or two had the cell walls pinched before being bent. It's mostly LST using less than 90 degree bends. Those orange 90 degree plant benders I used work well for tall slender branches. They just need to be taped on in order to maintain their hold on the branches that are somewhat slim.
Could you please show a close-up shot of your orange 90 degree plant benders and how it's used?
