I have flagged the callery pears on my placeI would give grafting a shot. I would also try planting a crab and another pear nearby to see if that would pollinate them. I think I had the same thing happening on my land with wild apples. I had no fruit and didn't even know I had wild apples trees. I had my land 20 years, 10 years ago I started planting some dolgo and then every year since a few more apples,pear, and crabs. I'm not sure what happened I think it was a combination of sunlight from tsi, and possibly the crabs and apples now pollinating the wild trees, but the wild apple/ crabs are popping up all over and they are really producing the fruit. Doing way better than my grafted trees.
plan to graft with some Keiffer scions from my orchard
Little to lose in terms of time or effort
who knows? Might even work1
