I have a pear tree in my back yard that was here when i moved in. I dont know much about pear trees except that i remember my grannie had one and that we had the best canned pears. i would like to know more about pruning and getting this tree in the best possible condition so that it can produce better fruit. I noticedafter we moved in that it is producing but it also had some wormd. Some of the pears are good. Also any tricks to keeping squirrels out of the tree?
