What's with this pear?
I have quite a few fruit trees, including several multi-graft pear trees. On one particular 4-graft dwarf pear tree that is about 5 years old, some of the fruit is misshaped and has some weird exterior cracking. I also had some pears on this tree exhibit this appearance and never get very big or ripe at all. The damage is superficial, and the fruit tastes fine. Still, I'm wondering if anyone can diagnose whether this is some type of disease, or underwatering, or something else. Thanks.
