Good evening, I hope all is well on your end! I purchased and planted two peach trees last year. At the time, my goal was to get the roots to thrive and the trees just to grow. This past spring, I pruned as best as I then knew how among the smaller new growth branches, trimming them back by 50%. Nevertheless, I recently started reading the ag extension documents on proper pruning of peach trees (scaffolding, sub scaffolding) and realized one of the trees I purchased was grown with one large upright watersprout that I left in place not knowing any better (see attached photos) because it looked most like a non fruiting tree. My question is whether i should cut this most vigorous “trunk” to try to cultivate a new scaffold branch and, if so, when should I do it? If I need to do it, should I do it now or should I wait until next spring. There are a lot of peaches growing on it and I worry that after already pruning a whole contractor bag worth of leaves it would put a lot of stress on the tree to cut 33% of its leaves off and expose a one inch wide section.
