How can you determine the health of your pecan tree

It can be. Photos will help me to confirm what is going on. This can be due to age, or fungal infections.
I don't know if your area is "boggy" or if you are far enough away from overly wet soil, but this would be a big factor in the health of your pecan. Wet soils can lead to severe infections for trees that are not designed to handle it.
