I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Your pear tree may still be trying to recover from the initial problem at planting. It is also possible that the soil is staying too soggy wet and the roots are drowning from lack of oxygen. You'll have to dig down a few inches into the soil around the root system and feel it to see if it need more or less water. Fix the soil moisture levels and the tree will have the best chance to recover.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
