2. Rich in Minerals
While the shells contain only small amounts of minerals, they contribute trace nutrients like potassium and calcium to the soil as they break down.
3. Improve Soil Drainage
Their porous, lightweight structure helps loosen compacted soil and improves aeration and water movement.
4. Natural Odor Absorber
Dry pistachio shells absorb smells in small spaces, making them useful for closets, shoes, refrigerators, and garbage bins.
5. Non-Toxic Pest Deterrent
Sharp edges and uncomfortable texture discourage cats, snails, and slugs from entering certain garden areas.
6. Eco-Friendly Fire Starter
The shells burn slowly and cleanly, making them excellent for fireplaces or outdoor grills.
7. Natural Scrubbing Agent
Crushed pistachio shells act as mild abrasives for cleaning pots, pans, and surfaces without scratching metal.
8. Perfect for Compost
They break down slowly but add long-term structure and minerals to compost piles.
