I for sure didn’t intend to single you out, but in general thought you were in the “let it go” chorus. Not that I’m against growing a dual trunk if it’s managed appropriately, but just pointing out I would almost never settle for the shape of tree the poster in that thread shows, over the tried an true method of a single low spreading tree w/ one trunk. And you are hearing it from someone who considers peaches a long term “annual”, not a perennial (so I’m not looking for peach trees in the super long term).
