Ok, have to ask, what is wrong with pear trees? Seems they would be good to have out there for the wildlife, if not personal consumption.
These are not your normal pear trees. These are demon spawn off a neighbor who has about 25 Bradford pears along his fence. As mentioned already, they have thorns that will go through a tractor tire and they will absolutely take over a area if not controlled. I despise them with a passion. The only benefit I've seen them have is rabbits seem to like the bark.
I would welcome actual pear trees. I'll most likely plant some in the future. I've got crabapples, American and Chickasaw plums, elderberry, indigo bush, sumac and American hazelnut all planted on my property along with 2500 short leaf pines. It's a weekly battle with the hybrid decorative pear trees. Just when I think I've got them all, I'll be going along and there'll be one head high and I'm left wondering how in the neck did I not see it.
