Eggshells, often dismissed as kitchen waste, are gardening gold. Rich in calcium carbonate, a mineral that’s essential for plant health, eggshells offer a sustainable and cost-effective way to enrich your garden.

Eggshells can play a key role in creating a vibrant, sustainable garden. From boosting plant growth to supporting wildlife and improving soil health, they can also boost plant growth. So, the next time you crack an egg, think twice before discarding the shell.

Here are 11 exciting ways to use it around the garden.

In the Compost

Adding eggshells to your compost pile is a simple way to increase the calcium content of your garden soil. This is crucial because calcium is key to strong plant cell walls. Crushed eggshells mix seamlessly into compost, eventually enriching the soil with nutrients that support healthy plant growth.
