You’re Doing It Wrong. How to Properly Use Eggshells as Fertilizer. | May 18, 2025

Eggshells, which most people think of as common kitchen scraps, can actually be a valuable asset to your garden soil. By reusing them, you are not only showing respect for the environment, but you are also providing your plants with important nutrients that are missing from many commercial fertilizers. But are you using them correctly?
If you know how to use eggshells properly, you can greatly increase their effectiveness. Many people throw them away or use them in a way that does not fully utilize their potential benefits. In this article, we present the proper techniques to fully utilize the potential of this surprising garden gem.
Nutrient Power Plant
Eggshells are composed primarily of calcium carbonate, a calcium-rich compound for plants. Calcium is essential for many plant functions, from the formation of cell walls to growth and development. Eggshells also contain small amounts of other important minerals, such as magnesium and potassium.
Why traditional methods are not enough
It may seem sensible to simply throw crushed eggshells into your garden, but that approach limits their usefulness. It can take a long time for unprocessed eggshells to break down and become bioavailable to plants. That delay means your garden won’t immediately benefit from the extra nutrients.
Correct preparation techniques
To fully utilize their potential, here are step-by-step instructions on how to properly prepare eggshells:
1. Clean the bowls
Rinse eggshells thoroughly and allow them to dry to avoid unpleasant odors and attracting pests.
2. Grind into a fine powder
Using a mortar and pestle or food processor, grind the eggshells into a fine powder. This will help the calcium in the soil break down faster.
