I did some reading around the forum about Pear Leaf Blister mites, and want to make sure I have this right.
I only see them on one limb of the tree which was grafted last year. The rest of the tree currently has marble sized E pears (unknown) on other limbs. I am guessing the grafted variety (Ubileen) is more susceptible to these pests.
Will the same limb be susceptible next year, meaning I need to spray that limb with Lime Sulfur spray (or maybe they will just not return naturally)?
Given where we are in the season, do I understand correctly: remove the affected leaves and don’t worry about any treatment?.. or should the leaves be left to help that graft from last year grow? I might have to remove most of the leaves on the graft.
