Failure of pecans to fill out can be due to poor soil nutrition, pests and diseases that cause leaf loss (e.g. scab, fall webworm), poor pollination, and/or drought. We do not have a pecan specialist at the University of Maryland Extension.
Why are there no pecans?
Failure of nuts to fill is caused mainly by insect and disease damage to leaves and an inadequate number of leaves. Drought also causes failure to fill, if it occurs late in the growing season. In many years lack of pollination causes the greatest loss of nuts.

How often should you trim a pecan tree?
Annual pruning is the most recommended method, which means you should never have to prune too much in one go.

Why are my pecans falling before they are ripe?
There could be several reasons, including plant physiology (pollination, nutrient requirement, canopy load), environmental stresses (drought, excess water), diseases (scab, powdery mildew, etc.) and insect pests (pecan weevil, twig girdlers, etc.).
Why are my pecans black inside?
Black pecan kernels are caused by stink bugs. While the pecans are small with soft shells, stinkbugs penetrate the shell and inject a chemical into the pecan which causes the pecan to decompose in that area.
Should pecans be soft or crunchy?
Soft pecans are not good and should be discarded. Pecans with an air gap in their cross section will not storage as well or as long as a full meaty nut. One reason for pithy pecan nut meats could be likely due to a fungal infection called “pecan scab”.

How do you increase pecan production?
Pecan trees grow best in well-drained sandy loam soil. Sandy soils will need to be fertilized often to maintain productivity, as nutrients will quickly leach through the large soil pore space of sand. Low fertility and an inadequate amount of zinc can limit nut production.
Which states produce the most pecans?
