We planted 3 cleveland select pear trees in our yard in 2020. Each year they have flowered. This year, 1 of them did not. I have fertilized them all evenly. It may be worth mentioning that the one that did not flower is extra low branching. The other two that did flower have branching that starts much higher. I am going to stop fertilizing going forward, but wonder if I should prune the lower branches from the one that didn't flower. Any suggestions would be very much appreciated.
You can remove those lower branches. Here is more on their care:
