Asian Pear Tree
I have an asian peter tree that is at least 20 years old on semi-drawf stock. The tree is espalier across a fence. It produces massive bloom and sets lot of fruit. I thin it very aggressively - 2 pears per spur. Over the past several seasons the ripe fruit is too small to bother with - despite my hard thinning. Perhaps I need to thin even more but is it possible the tree is simply old and tired. Or is it possible I need to provide the tree with supplemental nutrients? Thank you for your response.
I live in eastern Washington County.

Thank you. The tree appears healthy so it appears even more ruthless thinning will be in store it for next spring.
