Most people throw away eggshells without realizing how crucial they are!

Eggshells are a popular home waste item that is frequently discarded without consideration. However, these seemingly small eggshells hold enormous potential for gardening and plant growth. In this post, we’ll look at the several benefits of eggshells in the garden and how you can use this natural resource to improve the health of your plants and soil.

1. Nutrient-dense fertilizer. Eggshells are mostly made up of calcium carbonate, a mineral required for plant growth. Crushed eggshells can serve as a natural and inexpensive calcium source for your garden. How to make eggshell fertilizer:

Collect the eggshells and rinse them to remove any residual protein or membrane. Air dry the shells until they are brittle. Use a mortar or blender to break the eggshells into small bits or powder. Scatter broken eggshells around your plants or incorporate them into the soil. Calcium in eggshells reinforces cell walls, promotes root development, and helps to avoid tomato blossom end rot. It also adds minerals to the soil, which improves plant health.

2. Pesticides. Eggshells can act as a natural repellant for some garden pests. Crushed eggshells have sharp edges that can protect your plants against crawling insects such as snails, slugs, and caterpillars. Scatter crushed eggshells at the base of your plants to form a barrier that these pests are hesitant to cross.

3. Sow starter pots. Eggshells make great biodegradable seed containers. Fill each half-shell with potting soil, sow your seeds, and set them in an egg carton for support. When it’s time to transplant, simply smash the eggshell and place the entire thing in the garden. The eggshell decomposes, providing nutrients to the new plant.

4. Soil Improvement. Eggshells contain trace levels of magnesium and potassium, as well as calcium. When eggshells are crushed and incorporated into the soil, they strengthen its structure while also providing essential nutrients to your plants. Over time, this can result in healthier, more productive gardens.5. Compost Additive
Eggshells make an excellent addition to your compost pile.

Their calcium presence neutralizes the acidity of many kitchen wastes, resulting in a more neutral pH in the compost. Calcium also aids in decomposition and enhances the final compost with beneficial elements. 6. Natural pH regulator. If your plant soil is overly acidic, crushed eggshells can help raise its pH. This is especially useful to plants that prefer a more alkaline climate.

By putting eggshells into the soil, you can provide a more balanced and appropriate growing environment for your plants. 7. Tomatoes and Peppers
Eggshell treatments are especially beneficial for tomatoes and peppers. The calcium prevents blossom end rot, which is a typical problem with these plants. When planting or transplanting, mix broken eggshells into the planting hole to provide a consistent source of calcium throughout the growing season.
