Eggshells, don’t throw them away: soak them in hot water and see what happens

Eggshells are often thrown away, but they are a valuable resource for your garden. With the right preparation, they can improve soil quality and support strong plant growth.

Why Eggshells Are Good for Plants

• Contain about 93% calcium and small amounts of nitrogen and other minerals

• Support root development and strengthen plant cell walls

• Help balance soil pH when used in moderation

• Can improve soil structure and deter certain pests when used as mulch

Preparing Eggshells for Use

1. Wash and dry the shells to remove egg residue and prevent bacteria or fungus.

2. Dry for at least 24 hours before using.

3. Crush into small pieces or grind into a fine powder for better absorption.

Ways to Apply Eggshells

• Fertilizer: Mix crushed shells into soil or sprinkle around plant bases.

• Mulch: Spread larger pieces around stems to help retain moisture and reduce weeds.

• Compost: Add to compost piles to increase calcium content.

• Water infusion: Boil shells in water, let cool, and use the mineral-rich water for irrigation.

Extra Tips

• Avoid adding large amounts at once, as this can make soil too alkaline.

• For faster results, grind shells into a powder before applying.

• Use boiled shell water within 24 hours for maximum nutrient benefit.

Using eggshells in these ways recycles a natural resource and gives plants a steady supply of essential minerals. Over time, this can lead to healthier growth and stronger harvests.
