Although pistachio shells decompose slowly, they contribute to long-lasting humus that improves soil texture and water retention.
4. Use as a Natural Fire Starter
Thanks to their dense structure and natural oils, dry pistachio shells are ideal for starting fires in your fireplace, wood-burning stove, or outdoor fire pit.
How to make fire starters:

Why they work:
