I don’t know about peaches but ‘round my way the cider apple farmers spank the living daylights out of their high density dwarf trees. They get grubbed up and replanted in under a decade. Fruit trees have a naturally short lifetime but mega yield modern species are something else — the arboreal equivalent of a 40 day broiler.

Ironically, there’s a century year old perry tree at the top of the valley.
