I have a small quince tree in my yard. I can tell you that quince trees are about as hardy as the skin on the fruit itself is. I don’t know how the tree has survived this long. It’s bent over with its roots partly out of the ground. I feel guilty when I don’t use it but that tough skin is really hard to work with. When I do manage to get it peeled and cubed, I cook it with apples and raisins in brown sugar and water. Sometimes I make something resembling applesauce with it in the food processor. It’s tasty but I hate the work I have to go to to make it. I would willingly give the quince away if I could find someone who wanted them.
