Eggshells are a common household waste product, often discarded without a second thought. However, these seemingly insignificant eggshells have incredible potential when it comes to gardening and cultivating plants. In this article, we will explore the numerous valuable uses of eggshells in the garden and how you can make the most of this natural resource to boost the health of your plants and soil.
1. Nutrient-Rich Fertilizer
Eggshells are primarily composed of calcium carbonate, which is an essential mineral for plant growth. Crushed eggshells can be used as a natural and cost-effective source of calcium for your garden. To prepare eggshell fertilizer:
Collect eggshells and rinse them to remove any remaining egg white or membrane.
Air-dry the shells until they become brittle.
Crush the eggshells into small pieces or powder using a mortar and pestle or a blender.
Sprinkle the crushed eggshells around your plants or mix them into the soil.
The calcium in eggshells helps strengthen cell walls, promote root development, and prevent issues like blossom end rot in tomatoes. It also adds minerals to the soil, benefiting overall plant health.
2. Pest Deterrent
Eggshells can serve as a natural deterrent 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 cross.
3. Seed Starting Pots
Eggshells make excellent biodegradable seed starting pots. Fill each half-shell with potting soil, sow your seeds, and place them in an egg carton for stability. When it’s time to transplant, simply crush the eggshell and plant the whole thing into the garden. The eggshell will decompose, providing nutrients to the young plant.
