House plants bring life and beauty to our indoor spaces, but keeping them healthy and thriving can sometimes be a challenge. Fortunately, there’s a simple, natural solution that can help your house plants flourish continuously: eggshells. This everyday kitchen waste can be transformed into an effective and eco-friendly fertilizer. Here’s how you can use eggshells to boost the health of your house plants.

Benefits of Using Eggshells

  1. Nutrient-Rich:
    • Eggshells are packed with calcium, which strengthens cell walls and supports overall plant health.
    • They also contain small amounts of potassium and magnesium, essential for plant growth.
  2. Eco-Friendly:
    • Utilizing eggshells reduces kitchen waste and reliance on chemical fertilizers.
  3. Soil Improvement:
    • Eggshells help improve soil structure and drainage, promoting healthier root systems.

Materials Needed

  • Eggshells (from raw or cooked eggs)
  • Mortar and pestle or blender
  • Container for storage
  • Watering can

Step-by-Step Guide

  1. Collecting and Preparing Eggshells:
    • Rinse the eggshells thoroughly to remove any residual egg white or yolk.
    • Allow the shells to dry completely, either by air-drying or placing them in a low oven for a few minutes.
  2. Crushing the Eggshells:
    • Once dry, crush the eggshells into a fine powder using a mortar and pestle or a blender. The finer the powder, the more quickly it will release nutrients into the soil.
  3. Storing the Eggshell Powder:
    • Store the crushed eggshells in a sealed container until you’re ready to use them.
  4. Applying Eggshell Fertilizer:
    • Mix with Soil: When repotting plants, mix a few tablespoons of the eggshell powder into the potting soil. This helps incorporate calcium and other nutrients directly into the root zone.
    • Top Dressing: Sprinkle the eggshell powder on the soil surface around existing plants. Lightly scratch it into the top layer of soil to help it integrate better.
    • Watering Solution: For an immediate nutrient boost, steep a handful of crushed eggshells in water overnight. Strain the mixture and use the eggshell-infused water to irrigate your plants.

Additional Tips for House Plant Care

  1. Light:
    • Ensure your plants receive the right amount of light for their specific needs, whether it’s bright indirect light or low light conditions.
  2. Watering:
    • Water your plants consistently, allowing the soil to dry out slightly between waterings to prevent root rot.
  3. Humidity:
    • Many house plants thrive in higher humidity levels. Consider using a humidifier or placing a tray of water near your plants to increase humidity.
  4. Regular Feeding:
    • In addition to eggshell fertilizer, feed your plants with a balanced, water-soluble fertilizer during the growing season to ensure they receive all necessary nutrients.


Using eggshells as a natural fertilizer is an easy, cost-effective way to help your house plants flourish continuously. By incorporating this simple practice into your plant care routine, you can provide essential nutrients, improve soil health, and promote robust growth. Say goodbye to chemical fertilizers and hello to vibrant, thriving house plants with the help of this natural, eco-friendly solution.
