So my major tree-trimming lesson for this year is that spring growth (from overwinter root reserves) causes long, adventurous solo shoots but summer growth (from locally collected sunlight) causes bushier fractal growth, but available water is a limiting factor in both cases.
So in areas with rainy springs, after you thin out a canopy it’s important to keep the tree watered through summer so the holes opened up are filled in by adjacent branches poofing out rather than just new spring-growth branches from lower down.
