Eggshells are an inexpensive and useful resource that often end up in the trash after making breakfast. However, they are actually an incredibly versatile material with a wide range of uses around the home and garden. First of all, eggshells are an excellent fertilizer for plants. They are rich in calcium, which promotes strong growth and root development. To use the shells, simply crush them and add them to the soil around your plants – this will help improve the quality of the soil and saturate it with useful micronutrients.
Eggshells can also be used to control pests in the garden. Scattering pieces of shell around plants helps repel pests such as snails and slugs, which do not like the sharpness and texture of the shell.
