Why You Should Never Throw Away Eggshells

Why You Should Never Throw Away Eggshells

Stop Trashing Garden Gold!

Eggshells are approximately 95% calcium carbonate, an essential nutrient for plant cell growth. Throwing them away is like throwing away free fertilizer.

Prevent Blossom End Rot

Have you ever grown a perfect tomato only to find a black, rotting spot on the bottom? That is blossom end rot, caused by calcium deficiency. Crush eggshells into a fine powder and mix them into the planting hole when you set out your tomato seedlings.

Deter Slugs and Snails

Coarsely crushed eggshells create a jagged barrier that soft-bodied pests like slugs refuse to cross. Ring your hostas and lettuce with shells to keep them safe.

Seed Starters

Use half-shells as biodegradable seed starting pots. When the seedlings are ready, crack the shell slightly and plant the whole thing directly into the ground!
