Eggshells are a common household waste product that is often thrown away without concern. However, these seemingly insignificant eggshells have incredible potential when it comes to gardening and plant growing. In this article, we’ll look at the many valuable uses of eggshells in the garden and how you can make the most of this natural resource to promote the health of your plants and soil.
1. Nutrient-rich fertilizer
Eggshells are primarily composed of calcium carbonate, an essential mineral for plant growth. Crushed eggshells can be used as a natural and inexpensive source of calcium for your garden. How to prepare eggshell fertilizer:
Collect the eggshells and rinse them to remove any remaining protein or membrane.
Air dry the shells until they become brittle.
Using a mortar or blender, crush the eggshells into small pieces or powder.
Scatter the crushed eggshells around your plants or mix them into the soil.
The calcium in eggshells strengthens cell walls, promotes root development and prevents problems such as blossom end rot in tomatoes. It also adds minerals to the soil, which benefits overall plant health.
2. Pesticides
Eggshells can serve as a natural repellent against certain garden pests. The sharp edges of crushed eggshells can help protect your plants from crawling insects like snails, slugs and caterpillars. Scatter crushed eggshells around the base of your plants to create a barrier that these pests are reluctant to overcome.
