share 32

Gardening is a rewarding and therapeutic hobby that allows you to connect with nature, watch your efforts bloom, and enjoy the fruits of your labor. To cultivate a thriving garden, you need to provide your plants with essential nutrients. While there is a wide range of commercial fertilizers available, they often come with a hefty price tag and potential environmental concerns. Fortunately, you can turn to a natural and sustainable alternative: eggshell fertilizer.

Eggshell fertilizer is a DIY method that harnesses the power of crushed eggshells to provide valuable nutrients to your plants. By grinding eggshells into a fine powder, mixing them with water, and applying the mixture to your garden, you can enrich the soil with calcium and other minerals. In this article, we will explore the benefits of using eggshell fertilizer and guide you through the simple process of creating and applying it to your plants.

The Benefits of Eggshell Fertilizer

  1. Rich in Calcium: Eggshells are predominantly composed of calcium carbonate, which is a vital nutrient for plant growth. Calcium helps to strengthen cell walls, reduce the risk of diseases, and improve overall plant structure.
  2. Slow-Release Nutrient: Eggshell fertilizer provides a slow-release source of calcium, ensuring that your plants receive a steady supply of this essential mineral over time.
  3. pH Balance: Calcium carbonate can help buffer soil acidity, maintaining a healthy pH level for your plants to thrive.
  4. Pest Deterrent: The sharp edges of crushed eggshells can deter certain garden pests like slugs and snails, keeping your plants safe.
  5. Sustainable and Cost-Effective: Eggshell fertilizer is an eco-friendly solution that repurposes kitchen waste and saves you money on commercial fertilizers.

How to Make and Apply Eggshell Fertilizer

Materials You’ll Need:

  • Eggshells
  • A mortar and pestle, coffee grinder, or food processor
  • A container for storing the crushed eggshells
  • A spray bottle (optional)


  1. Collect Eggshells: Start by saving and rinsing eggshells after cooking or baking. Allow them to air dry to remove any residual moisture.
  2. Crush the Eggshells: Once dry, crush the eggshells into a fine powder. You can do this using a mortar and pestle, a coffee grinder, or a food processor. Ensure the shells are ground into a consistent, fine texture.
  3. Store the Eggshell Powder: Keep the crushed eggshells in a container with a secure lid. This way, you can easily access them when needed.
  4. Mix with Water: When you’re ready to fertilize your plants, take a few tablespoons of the eggshell powder and mix it with water. You can either pour this mixture at the base of the plant or strain it and transfer it to a spray bottle for more even distribution.
  5. Application: If you choose to spray the mixture, apply it directly to the leaves and soil around your plants. For base application, pour the mixture around the root zone, avoiding contact with the leaves.
  6. Repeat as Needed: Apply the eggshell fertilizer every few weeks or as required, depending on the specific needs of your plants.


Eggshell fertilizer is a natural, cost-effective, and sustainable way to boost the health and vitality of your garden. By repurposing kitchen waste and providing your plants with essential calcium and other minerals, you can witness your garden thrive while minimizing the use of commercial fertilizers. Plus, the added benefit of deterring garden pests makes it an even more attractive choice. Give eggshell fertilizer a try, and watch your garden flourish with the help of this secret ingredient from nature.
