Ah, man, a few trees where over the last few years I had trimmed major branches or multi-trunks and opened up big gaps in the canopy but told myself the adjacent stuff would grow to fill in and this year yeah.

Taking off lower branching also saw to it that root-reserve spring growth was preferentially focused up high, there was one pinnate-leafed one where I found that one branch doesn’t fully block sun and all the parallel ones had been additive, but having thinned them out the remaining ones sent off lateral shoots that are growing to thatch the whole canopy together.
