I have this Exbury azalea that would seem to lend itself well to broom style, but I have never attempted a broom before. I've done some research and it seems like you still need an upright leader, with branches around the periphery. Looking at this image, please indicate which branches you'd keep, and which you'd cut to best facilitate a broom style. It has inverse taper, but oh well. Let me know if you need close up pics from various angles. Thanks for your help!
