Most people throw away eggshells without realizing how important they are!


Eggshells are a common household waste that is often disposed of without much thought. Yet, these seemingly small eggshells hold tremendous potential for gardening and plant growth.

In this post, we’ll explore the various benefits of eggshells in the garden and how you can harness this natural resource to improve the health of your plants and soil.

1. Nutrient-rich Fertilizer: Eggshells are mostly made of calcium carbonate, a mineral essential for plant growth. Crushed eggshells can serve as a natural and cost-effective calcium source for your garden. Here’s how to make eggshell fertilizer:

– Collect eggshells and rinse them to remove any protein residue or membranes. Air dry the shells until they become brittle.
– Crush the eggshells into small pieces or powder using a mortar and pestle or a blender. Spread the crushed eggshells around your plants or work them into the soil.

The calcium in eggshells strengthens cell walls, promotes root development, and helps prevent blossom end rot in tomatoes. It also introduces minerals into the soil, improving plant health.

2. Pest Control: Eggshells can act as a natural deterrent against some garden pests. Crushed eggshells have sharp edges that can protect your plants from crawling insects like snails, slugs, and caterpillars.

Spread crushed eggshells at the base of your plants to create a barrier that these pests are reluctant to cross.

3. Seed Starting in Eggshells: Eggshells make excellent biodegradable seed containers. Fill each eggshell half with potting soil, sow your seeds, and place them in an egg carton for stability.

When it’s time to transplant, simply crush the eggshell and plant the whole thing in the garden. The eggshell will decompose, providing nutrients to the new plant.

4. Soil Amendment: Eggshells contain traces of magnesium and potassium along with calcium. When crushed and incorporated into the soil, they improve its structure while providing essential nutrients to your plants.

Over time, this can lead to healthier and more productive gardens.

5. Compost Addition: Eggshells are an excellent addition to your compost pile. Their calcium content neutralizes the acidity of many kitchen scraps, leading to a more neutral pH in the compost.

Calcium also aids in the decomposition process, enriching the final compost with beneficial elements.

6. Natural pH Regulator: If your soil is too acidic, crushed eggshells can help raise its pH level. This is particularly useful for plants that prefer a more alkaline environment.

By incorporating eggshells into the soil, you can provide your plants with a more balanced and suitable growing environment.

7. Tomatoes and Peppers: Eggshell treatments are particularly beneficial for tomatoes and peppers. The calcium prevents blossom end rot, a common issue with these plants.

Mix crushed eggshells into the planting hole when planting or transplanting to provide a continuous source of calcium during the growing season.

Don’t underestimate the value of eggshells in gardening. These seemingly insignificant breakfast remnants can be a great resource for enhancing the health and productivity of your plants.

Eggshells are nutrient-rich and act as pest deterrents; they have numerous applications in the garden. So, next time you crack an egg, think carefully before discarding the eggshells.

Give them a second chance in your garden, and your plants will thrive thanks to the natural benefits of these sometimes overlooked treasures.
