After they completely break down on the tree, they really are good and make an excellent paste like a pear apple sauce mix. Here in southern Michigan the biggest problem is with fire blight and some type of canker that infests certain cultivars. So far the Russian cultivars were hit the hardest. The French ,German varieties and seedlings from a plant I found in Michigan at an old nursery are really productive every other year. All grow without insect pests. The deer and turkey eat the fruit in the winter. They love it like persimmons.
