I planted an Elberta peach tree in spring of 2017. It was much smaller then - about 4 ft. tall and probably not much over 1/2" in diameter. It grew well last year but this year it has really taken off! It's now at least 8 feet tall (and putting on height fast) and is probably 2" in diameter at the base. (Augusta, GA, by the way.)

I pruned it shortly before this spring, doing my best to select what could serve as 4 limbs of an open-vase structure. But, as you can see, one of the lower branches not only became *extremely* vigorous, it has also grown at a fairly steep angle to the main upright.

If the low, steep crotch is ultimately going to have to go - since it might eventually split the tree once it's all larger and bearing fruit - would it be better to go ahead and take it off NOW so the tree can devote what remains of the growing season to putting more size on the main upright and laterals?

Or would it be better to leave it for now and let the tree get through this entire growing season before pruning again? That branch that forms the right side of the steep crotch is the most vigorous part of the plant right now - although it's growing all over.

Also, I've left two fruits on the tree at this point. Should I take them off before they grow any further?

I'm a first timer at this, so I'd appreciate any other advice for pruning any experienced peach growers would care to offer! Here's one more photo, in case it's helpful. And THANKS for reading!
