Answer: Sounds as though your tree isn't getting adequate water or nutrients during development of the fruit. Pecan trees need deep soakings during the spring and summer months when growth and fruit production are at their highest. Your tree might need a little boost in the form of fertilizer, applied in the early spring, after growth begins. There are fertilizer stakes available, or you can broadcast granular 12-6-6 at the rate of one pound per inch of trunk diameter. Rake it into the soil lightly and then water well.
Hope your pecans are nice and plump next season!
