Eggshell itself is a natural fertilizer that can be used during composting to increase calcium in the soil. It is best to wash the eggshells, dry them, crush them into powder, and then sprinkle them into the soil, which will slowly increase the nutrients in soil.


For those who like to grow peppers or tomatoes, it is very important to add some eggshell powder to the soil. Because these plants are susceptible to fungal diseases once they are deficient in calcium, they can even cause flowers to fall and fruits to rot.

To do this, encircle roughly crushed layer of eggshells around the plants that are sensitive to such pests.

This will also help in healthy growth of tomato plant and develop its resistance to diseases, especially against blossom end rot occurs due to lack of calcium.


5. Eggshell potted

Eggshells can also be used as delicate containers. After the top part is broken, the egg white and yolk is clean out, wash with water properly, and dry. At the bottom of each half shell, do a small hole, for drainage. Fill it with meager amount of soil and sow seeds.
