If you have harvested pecan nuts prematurely, then it is likely that their moisture content would be high. You’d need to dry the pecans in the shell completely so that you can crack them open easily.

Pecan trees thrive abundantly in the South US, especially in the catchment area of the Mississippi River. Pecan tree grow to a height of nearly 80-100 ft and appear striking and magnificent owing to their thick canopy. The trees are cultivated extensively in the Southern US, chiefly because of their seeds or nuts that taste delicious.
