Eggshells aren't just meant to be thrown away; they can also become a valuable ingredient for making your own natural garden fertilizer. Here's how to turn waste into a calcium-rich amendment for your plants:
1- Keep your eggshells after using them in cooking. Rinse them lightly to remove any egg white residue, then let them dry completely.
2- Once dry, grind them using a mortar and pestle, or by passing them through a coffee grinder. Make sure to grind them into a fine powder for better dissolution in the soil.
3- Spread eggshell powder directly in your garden or mix it with your compost. The calcium in the shells helps strengthen the cellular structure of plants, promoting growth and resistance to disease.
By using eggshells as a garden fertilizer, you reduce food waste while providing your plants with a natural amendment beneficial to their health. In addition, you reduce your costs since commercial fertilizer is expensive.
