If they're shuttering this farm because peaches are no longer profitable, why would someone else pay for these trees?

Unfortunately it’s way more economical to chip them over spaying out a full sized tree then meshing and wiring it, lifting the heavy thing with roots and soil onto a flat bed for one off transplant - every step requires heavy diesel fueled equipment. Plus, older trees have higher risk of dying and you really need to do it in the winter.

It’s actually cheaper just to buy new fruit tree stock and you can get better quality (ie flavorful varieties vs mass farmable ones). Source: worked at an ornamental tree farm, done the math in spreadsheets and have planted peach trees in my yard as well - once loaded a trailer wrong and did a 180 in a loaded flatbed with trees, which went all over the interstate.
