I have a handful of Kieffer pear trees I purchased from Lowes a couple years ago. I didn’t prune them at planting, but after a year I tried to shape them with a central leader style. Most have 4-5 branches all the same size starting around the same spot. I keep reading different things with pear trees. Some say prune to central leader, some open center, some leave them alone for a few years then prune. What is the best bet? They all look like the central leader was cut when I bought them from the store. I hope I really didn’t mess them up already. A few I didn’t have high enough fencing for and deer ate most of the side branches. I have since protected them, but now the trees look worse than when I planted them. Any advice would be appreciated.
