Hi My pear tree had an abundance of blossoms this year, and they stayed for quite a while. Many of them have shriveled and died without producing fruit. The tree is (I believe) a Bartlett. It was well established when I moved in 25 years ago. I do not use any spray or fertilizer on it. Also - a few years ago the flavor of the pears was extraordinary, unlike any other. I sometimes wonder why that happened, but it’s not my main question. Thank you!!
