Q: I have a rather large peach tree that doesn’t produce very well. I didn’t prune it properly at the beginning so it’s about 15 feet tall with lots of branches and doesn’t have an open center.
A: A short trunk with widely extending branches and an open center is the ideal shape for a peach tree but it is not absolutely required. You might get a few less peaches when a tree is lrft unpruned but nothing drastic. You could open up the center by pruning the trunk down by four or five feet. This would leave a relatively tall trunk but there should be limbs below that point that will spread wide in the future. Keep an eye on the spot where you did the trunk pruning. You will probably have to remove new sprouts from that point every winter.
