How to CORRECTLY Extract Calcium from Egg Shells for Healthy Plants

Introduction

This tutorial will guide you through the correct method of extracting calcium from egg shells to promote healthy plant growth. Simply crushing egg shells and adding them to your soil is not effective, as they take 2-5 years to break down. Instead, we will explore a more efficient approach to provide your plants with the essential calcium they need.

Step 1: Collect and Clean Egg Shells

• Gather used egg shells from your kitchen.
• Rinse the shells thoroughly to remove any egg residue, which can attract pests.
• Allow the shells to dry completely. This can take a few hours or overnight.

Step 2: Bake the Egg Shells

• Preheat your oven to 200°F (about 93°C).
• Spread the dried egg shells on a baking sheet in a single layer.
• Bake for 10-15 minutes. This will sterilize the shells and make them easier to grind.

Step 3: Grind the Egg Shells

• Once cooled, transfer the baked shells to a blender or food processor.
• Blend until you achieve a fine powder. This can take a few minutes; stop occasionally to stir the mixture for even grinding.
• Ensure there are no large pieces remaining, as these will not break down quickly in the soil.

Step 4: Incorporate Calcium Powder into Soil

• Mix the ground egg shell powder into your soil or potting mix before planting.
• Use approximately 1-2 tablespoons of powder per planting hole or per pot, depending on the size.
• For existing plants, sprinkle the powder around the base and lightly work it into the topsoil.

Step 5: Monitor and Maintain Soil Health

• Water the soil after adding the egg shell powder to help it integrate.
• Monitor your plants regularly for signs of calcium deficiency, such as blossom end rot in tomatoes.
• Reapply the calcium powder every few months if needed, especially during the growing season.

Conclusion

By following these steps, you can effectively provide your plants with calcium through properly prepared egg shells. This method ensures that the calcium is readily available to your plants, promoting healthier growth and improving yields. Consider keeping a supply of egg shell powder on hand for ongoing plant care. Happy gardening!
