How to Use Pistachio Shell Powder in the Garden

1. Natural Soil Amendment
Mix the powder into garden soil to improve aeration and structure, especially in compacted soil.

2. Slow-Release Minerals
Pistachio shells contain trace minerals like calcium and potassium that break down slowly and enrich the soil over time.

3. Pest Deterrent (Light Use)
Sprinkle a thin layer around plants—sharp particles may discourage crawling pests like slugs and snails.

4. Compost Booster
Add the powder to your compost pile to increase carbon content and balance green materials.

• Apply sparingly—this is a supplement, not a fertilizer replacement

• Works best mixed into soil rather than left on the surface
