They may just be too young, about 20 years now.
Or they may be the wrong combo. Pecan trees are each either M/F -- male flowers before female flowers --, or the opposite, F/M. In order for trees to set fruit, there needs to be both F/M and M/F trees mixed together in the area, so that the female flowers can receive pollen from male flowers.
As far as I know, I have the only two pecans in the area. They may be of the same type. Pecans will cross-pollinate with Hickory trees, but my one hickory tree is too small. Pecans will not cross-pollinate with Black Walnut or Butternut trees.
