Why don't my pears get ripe?


I suggest that you try thinning the fruit from the tree in late May or early June. Thin to one pear per spur, and every other spur should have no pears. This makes it easier for the tree to put the necessary energy into each pear. Don't leave any clusters of fruit. Then to eliminate the codling moth worms make one spray with Spinosad in late May, one in late June, and one in late July before picking. If the pears stay on the tree longer make a spray in August too.

I think because of the heavy set you allow on the tree, the excess fruit starts falling early in July. Most pears are best left on the tree into September or October. Once you pick the fruit put them in a cold place, ideally a refrigerator for a month or two. Winter pears all need a cold spell to ripen properly. After being in the refrigerator take a few out and leave them at house temperature when you want them to soften. This usually helps winter pears to soften more uniformly.
