Do Not Rush to Throw Away the Eggshell — You Can Make an Effective Fertilizer from It

The humble eggshell is a highly effective fertilizer for a variety of plants. Whether you’re growing flowers, lettuce, currants, carrots, cherries, or onions, eggshells can be a natural, eco-friendly way to nourish your garden. You can either crush the shell into a fine powder or make an infusion to feed your plants.

How to Prepare Eggshells for Fertilizing

To create your own eggshell fertilizer, start by grinding the shell. You can use a meat grinder, hammer, or coffee grinder to break the shell into small pieces or powder.

• Powdered eggshell helps deacidify the soil and can be directly applied to garden beds during planting. If your soil is particularly acidic, you can use up to 1000 grams of powdered eggshell per 1 m². However, this amount may be excessive for some soils, so apply it selectively.
• Shredded eggshell can also help protect plants from pests like wireworms, nematodes, and roach larvae. To use this method, scatter the crushed shells over your garden beds before winter.

Eggshell Infusion for Plant Feeding

For an even more effective fertilizer, you can create an eggshell infusion:

1. Infuse the powdered eggshell by pouring boiling water over it and letting it sit for a week. During this time, make sure to cover the container with a lid.
2. The resulting infusion will be cloudy and have an unpleasant smell, which is normal. Before use, dilute the mixture with water at a ratio of 1 part infusion to 3 parts water.

Alternatively, you can use a simpler method by pouring 500 ml of powdered eggshell into 3000 ml of boiling water. Let it sit for a day, then filter the solution and refill it with water for a second infusion.

How to Collect and Store Eggshells

To make your eggshell fertilizer, follow these simple steps:

1. Rinse the eggshells with water to remove any leftover egg residue.
2. Crush or grind the shells as described above.
3. Store the prepared shells in a cardboard box until you’re ready to use them in your garden.

By using eggshells as a natural fertilizer, you’re providing your plants with calcium, minerals, and other nutrients, all while reducing waste. Happy gardening!
